At November 17, 2021, The Honorable Dale Nally, Associate Minister of Natural Gas and Electricity, presented Bill 86, the Electricity Law Amendment Act, 2021 (ESAA), in the Legislative Assembly of Alberta. With the ESAA, the Government of Alberta (the Government) is taking action to modernize an Alberta electricity system in transition. The rapid evolution of technology, including that related to energy storage and renewable energy production, as well as a number of recent decisions and investigative reports from the Alberta Utilities Commission (AUC ), have all contributed to the changing landscape of electricity generation, transmission and distribution in Alberta.

The government appears to recognize these challenges and opportunities, saying the ESAA “will help build investor confidence in the Alberta power grid and support a modern and innovative power system.” More precisely, the ESAA proposes to

  • Create a new regulatory framework specifically for energy storage;

  • Allow unlimited self-supply and export; and

  • Introduce the planning of the distribution system.

To achieve these goals, the ESAA will amend the three main laws governing Alberta’s electricity grid: Alberta Public Utilities Commission Act, the Electricity Utilities Act (EUA) and the Hydraulic and Electric Power Act (HEEA).

The changes to the ESAA will be accompanied by changes to other regulations, and possibly new regulations, and the government intends to have the ESAA promulgated at the same time as the related regulations come into force, d ‘by the end of 2022.

The changes will create new opportunities for companies in the electricity generation and storage sector. Many details still need to be worked out, especially in new or amended regulations, and companies in the power sector need to stay informed and active in government relations and up to date with AUC and Alberta Electric developments. System Operator (AESO).

Although the ESAA has not yet passed first reading, for convenience we refer here to the proposed amendments in the ESAA as changes that will occur.

ENERGY STORAGE

Grid-scale energy storage, largely battery energy storage, is in the early stages of growth in the Alberta market. Alberta’s first grid-wide battery storage project, TransAlta’s WindCharger battery storage project, did not come online until the end of last year, and most projects in Energy storage have so far been offered as part of larger power plants. Both AESO and AUC are adapting to this new technology, with an ongoing commitment to the AESO energy storage roadmap and AUC having recently created a new section of its rule. 007, which details the information that should be included in different types of AUC applications. , applicable to battery storage facilities.

The new arrangements for energy storage in the ESAA will provide a framework for these existing processes of regulatory change. This new framework creates a completely new and distinct category of energy facilities for which AUC approval is required, energy storage facilities. The legislative framework for energy storage facilities will largely parallel the existing framework for power plants. The new AUC rule 007 requirements for battery storage facilities may guide the type of information required for energy storage facility applications under the ESAA, but the AUC may also develop a new section of rule 007 more directly in line with the implementation of ESAA.

Owner of the transmission and distribution network Ownership of energy storage

ESAA will allow Distribution Facility Owners (DFOs) and Transmission Facility Owners (TFOs) to own energy storage and recoup the costs of that ownership, but only in limited circumstances. These limitations will tend to prioritize competitive public procurement.

First, if DFOs and TFOs choose to own energy storage, the costs and expenses of that storage will be recoverable in their tariffs, but it is not clear whether this will be on a flow-through or capitalized basis – This is not yet the case. to be determined. In addition, it is not clear whether DFOs and TFOs that own energy storage will be able to sell electricity from that storage to the grid.

In addition, DFOs in particular will only be able to own energy storage facilities if that property is approved by the AUC. The AUC can approve such a request only in limited circumstances that encourage competitive procurement of non-wired services prior to or in lieu of DFO ownership of energy storage facilities, in most cases.

TFOs will not be subject to a general ban on owning energy storage facilities. However, only energy storage facilities that are part of the needs identification documents requested by the AESO and approved by the AUC will be part of the transmission lines under the HEEA, placing a large part of the decision-making for the development of energy storage based on the transmission network on the AESO.

SELF-SUPPLY AND EXPORT

Self-supply is currently prohibited by the interpretation of the AUC of the EUA and the HEEA, with the exception of designated industrial systems that generate electricity as part of an integrated industrial process, of certain municipal sites, micro-generation installations of less than 5 megawatts (MW) and gas-generating flares.

ESAA will remove this ban, allowing any market player to produce electricity, consume part of this electricity on site and sell electricity to the grid via the Power Pool. This can create opportunities for electricity users to more economically meet their own electricity needs while exporting to the grid when they generate excess electricity or when it makes sense to do so.

However, self-supplied market participants will have to pay a fair and reasonable portion of the costs of the transmission system, as determined by AESO in its tariff. These costs will be billed directly to market participants who are connected to the transmission system and to DFOs with self-supplied customers. The ESAA will allow but will not require the AESO to charge this tariff on a gross basis over all generation and consumption of electricity by a self-supplied market participant, and not just on what the participant to the market consumes and exports to the network.

The ESAA will also confirm that industrial systems continue to be able to self-supply and export, and that industrial systems will not have to pay the new tariff covering self-supply.

The self-provisioning changes in the ESAA reflect many of the findings of the Do-It-Yourself Sourcing and Exporting – Alberta Utilities Commission Discussion Paper published on June 5, 2020 and, as shown here, how self-supply and export will be treated financially will ultimately be determined in a future AESO tariff proceeding.

PLANNING THE DISTRIBUTION SYSTEM

Related to issues of energy storage and self-supply, but also with broader implications, the ESAA will place an obligation on MPOs to prepare distribution network plans, assuming the Minister leads the preparation of these plans in the regulations, and the obligation to make decisions on “non-wired services” as part of their decisions regarding the construction, modernization and improvement of the electrical distribution system.

To align with this new obligation, the ESAA will grant the Minister the power to make regulations regarding the plans of the electrical distribution system, including with respect to their objectives and goals, the information that must be included, as well as than their timing, frequency and sharing. Much of the impact of ESAA in terms of distribution system planning will be determined by these regulations.

CONCLUSION

While the changes to the EESA will affect both transmission and distribution networks, they address many of the concerns raised by the recent Final report of the distribution system survey published on February 19, 2021, which addressed the regulatory and economic challenges of distributed energy resources, including energy storage and self-provision. However, the Distribution System Survey, while concluding that self-sufficiency issues, including the contributions of self-sufficiency market participants to transportation costs, were a “primary issue”, also noted that there were positive opportunities to be seized through the integration and appropriate pricing of distributed energy resources (Distribution System Survey, paragraph 258). ESAA is starting to capitalize on these opportunities, but many ideas such as value-added pricing, prioritization of wireless alternatives, and integrated system planning have yet to be addressed.

Ultimately, the development of a modern electricity grid capable of effectively achieving the intended policy objectives will require the contribution and commitment of all electricity stakeholders. As the AUC stated in the Distribution System Investigation Report, “The continued evolution of the electricity system will require thoughtful planning and actions on the part of the distribution utilities, the Commission and the Commission. other stakeholders ”(Distribution System Survey, paragraph 497). We will continue to monitor developments in this area.

A new report from the International Energy Agency (IEA) projects that India is expected to add 121 gigawatts (GW) of electricity to its current capacity from clean energy sources by 2026. The agency predicted an 86% jump from its current capacity of 154.9 GW. The report says renewable energy could account for nearly 95% of the increase in electricity capacity worldwide over the next five years.

The ability to generate electricity from solar, wind and other renewable technologies is set to accelerate over the next few years, with 2021 set to set a new all-time record for new installations. , according to the report, taking into account a drop of 44%. in renewable facilities in 2020 in India due to the lockdown and supply chain disruptions caused by Covid-19.

“Renewable energy growth in India is exceptional, supporting the recently announced government target of reaching 500 GW of renewable energy capacity by 2030 and highlighting India’s wider potential to accelerate its transition to clean energy, “IEA Executive Director Fatih Birol said in a statement.

The report predicted a 16% increase in power wind and hydroelectric power generation, while solar remains the engine of renewable electricity growth, with its capacity additions expected to increase by 17% in 2021 to reach a new record of nearly 160 GW.

The report also highlighted the critical challenge facing distribution companies (DISCOM) in India, stating: “Government financial support in 2020 has resulted in a downward trend in overdue payments in the first quarter of 2021, thereby improving corporate finances. Following the second wave of restrictions, their total payment arrears started to rise again in the second quarter of 2021. As a result, they are postponing the finalization of the wind and solar PV PPAs while seeking to renegotiate downward the prices of the already existing contracts. awarded through competitive tenders. “

At the recent COP26 summit in Glasgow, India announced that it would meet 50% of its energy needs through renewables by 2030, increasing its non-fossil energy capacity to 500 GW during the same period and increasing the carbon intensity of its economy. up to 45 percent.

The report also says that if the government steps up clean energy production, it could put the country firmly on track to meet the 2030 goals.

“Governments can further accelerate the growth of renewables by addressing key barriers, such as licensing and grid integration issues, issues of social acceptance, inconsistent policy approaches and insufficient remuneration. High financing costs in the developing world are also a major obstacle, ”the report says. Noted.

The report further predicts that global renewable energy capacity this year will reach a second consecutive all-time high in 2021.

In its annual report on the renewable energy market, the Paris-based energy watchdog said that renewable electricity capacity by 2026 will be equal to the current total global electricity capacity of fossil fuels and electricity. nuclear power combined.

Meanwhile, China leads the world in new capacity and is four years ahead of its own targets for wind and solar infrastructure. “China continues to demonstrate its strengths in clean energy, with the expansion of renewable energies suggesting that the country may well reach a peak in its carbon dioxide emissions well before 2030,” Fatih Birol added.

From John Adams, Minna

Youth under the auspices of the Coalition of Youth Associations of Shiroro in Niger State gave the federal government a two-week ultimatum to respond to their demands for adequate compensation from communities displaced as a result of the construction of the dam .

The youth association is also asking that the name “Zungeru dam” be replaced by “second Shiroro or Manta dam” since ninety-five percent of the land occupied by the dam is located in the local government area of Shiroro and not in the Wushishi local government area which contributed only five percent of its land to the construction of the dam.

Youth Coalition spokesman Comrade Salis Sabo said this while addressing reporters at the Kuta headquarters of the Shiroro local government area over the weekend, warning that the federal government should forget the date of commissioning from December 2021 as promised by Energy Minister Babatunde Fashola if their demands are not met.

Comrade Salis Sabo, who described as pathetic the situation of people from these communities displaced as a result of the dam’s activities, stressed that the young people will explore all avenues to assert their demands, including “taking legal action and obtaining a court order prohibiting the federal government from commissioning and continuing work on the multibillion naira Zungeru hydroelectric dam ”.

Comrade Salis Sabo further explained that they will additionally occupy the dam premises as part of a peaceful protest against the commissioning of the 700 megawatt Zungeru hydroelectric dam after having exhausted all constitutional means to seek redress.

According to him, they will also have petitioned the World Bank for the inability of the federal government to fulfill its terms of the agreement and the conditions for obtaining a loan from an international financial institution to finance the dam project. Zungeru hydropower plant.

The president of the Shiroro Youth Association, Comrade Usman Ibrahim Kuta, also wants those whose properties were not captured during the initial exercise to be captured and assessed with particular attention to those who have lost their property. land and became homeless as a result of the activities of the Shiroro Dam project.

A victim and village chief of Bawyi Malam Isa Usman Kuta, also speaking, lamented that more than 50 communities have been affected by the Zungeru dam project and that properties worth hundreds of millions of naira have been lost. destroyed while many people died from trauma they suffered due to the non-payment of their compensation and therefore called on the federal government to come to their aid.

The chairman of the Shiroro Local Government Council, Mallam Suleiman Dauda Chukuba, assured in his address to the young people of the governments to support their demands at all times in other media.

He then called on the federal government to provide adequate compensation and resettle affected communities to alleviate their hardship.

The Sahofika hydroelectric project is now fully in its construction phase. Its developer, New Hydroelectric Power from the Onive (NEHO), has signed a concession agreement with the Malagasy Ministry of Energy and Hydrocarbons. NEHO is responsible for the financing, construction, operation and maintenance of the future hydropower plant. The site chosen for its construction is located 100 km from the city of Antananarivo.

The future power station will operate thanks to a dam built on the Onive river. The facility will have a height of 60 m and a crest width of 2 km. The reservoir will occupy an area of ​​8.9 km2. The hydroelectric power station will be the largest on the island, with a production capacity of 192 MW.

A 25-year PPA

The ad hoc company NEHO is majority owned by the Moroccan investment company Themis, but also by the pan-African group Eranove and Eiffage, a construction and concession group based in Vélizy-Villacoublay, France. The consortium also signed a 25-year electricity purchase contract (PPA) with the public company Jiro sy rano Malagasy (JIRAMA).

“The completion of the Sahofika hydroelectric project is the cornerstone of the transformation of the electricity sector in Madagascar. The project will allow a transition to green energy and a reduction of more than 30% of the average purchase cost for JIRAMA ”, explains Tas Anvaripour, Managing Director of Themis. The construction phase of the project is expected to last 5 years from the start of construction. NEHO estimates that the electricity produced in Sahofika should supply at least 1.6 million Malagasy households.

The project is supported by the African Development Bank (AfDB), which is in charge of syndicating its debt, and has already approved the establishment of a partial risk guarantee of up to $ 100 million. The Pan-African bank has also requested a senior loan of $ 100 million. The AfDB is also financing the construction of a 220 kV power line to evacuate the electricity produced at the Sahofika hydroelectric power station.

A new report from the United Nations Economic Commission for Europe (UNECE) that has examined the life cycle of carbon produced by all technologies suggests that nuclear power generates fewer carbon dioxide emissions over the course of of its life cycle than any other source of electricity.

In its analysis of life cycle greenhouse gas emissions, the commission found that nuclear has the lowest carbon footprint, measured in grams of CO2 equivalent per kilowatt hour (kWh) of electricity, of all technologies. .

Candidate technologies being evaluated include coal, natural gas, hydropower, nuclear power, concentrated solar power (CSP), photovoltaics and wind power. Twelve global regions included in the assessment, allowing varying load factors, methane leakage rates or background grid power consumption, among other factors.

  • Coal power shows the highest scores, with a minimum of 751 g CO2 eq./kWh (IGCC, USA) and a maximum of 1095 g CO2 eq./kWh (pulverized coal, China). Equipped with a carbon dioxide capture installation, and taking into account the storage of CO2, this score can drop to 147-469 g CO2 eq./kWh (respectively).
  • A combined cycle power plant with natural gas can emit 403 to 513 g CO2 eq./kWh from a lifecycle point of view, and between 49 and 220 g CO2 eq./kWh with CCS. Coal and natural gas models include methane leaks during the extraction and transport phases (for gas); however, direct combustion dominates life cycle GHG emissions.
  • Nuclear power shows less variability due to the limited regionalization of the model, with 5.1 to 6.4 g CO2 eq./kWh, the fuel chain (“upstream”) contributes the most to overall emissions.
  • On the renewable side, hydroelectricity shows the greatest variability, as the emissions are very site specific, ranging from 6 to 147 g CO2 eq./kWh. Since biogenic emissions from sediment accumulated in reservoirs are mostly excluded, it should be noted that they can be very high in tropical areas.
  • Solar technologies generate GHG emissions ranging from 27 to 122 g CO2 eq. / KWh for CSP, and from 8.0 to 83 g CO2 eq. / KWh for photovoltaic, for which thin-film technologies are significantly less carbon-intensive than silicon-based PV. The upper range of GHG values ​​for CSP is probably never achieved in reality as it requires high solar irradiation to be economically viable (a condition that is not met in Japan or Northern Europe, for example) .
  • Wind power GHG emissions vary between 7.8 and 16 g CO2 eq./kWh for onshore wind turbines, and 12 and 23 g CO2 eq./kWh for offshore wind turbines.

Most of the GHG emissions from renewable technologies are incorporated into the infrastructure (up to 99% for photovoltaics), which suggests strong variations in the impacts of the life cycle due to the origin of the raw materials, the energy mix used for production, the modes of transport at different stages of manufacturing and installation, etc. As the impacts are incorporated into the capital, the load factor and the expected lifespan of the equipment are naturally very influential parameters on the final LCA score, which can considerably decrease if the infrastructure is more durable than expected. .

Ionizing radiation occurs primarily as a result of radioactive emissions of radon-222, a radionuclide found in tailings from uranium mining and grinding for nuclear power generation, or from coal mining for power generation charcoal. Coal-fired energy is a potentially important source of radioactivity, as the combustion of coal can also release radionuclides such as radon-222 or thorium-230 (very variable depending on the region). Growing evidence that other energy technologies emit ionizing radiation during their lifecycle has been published, but no data was collected for these technologies in this study.

Human toxicity, non-carcinogenic, has been found to be strongly correlated with arsenic ion emissions linked to the landfill of mining residues (coal, copper), which explains the high score of coal power on this indicator.

Carcinogenic effects are found to be high due to chromium VI emissions linked to the production of stainless steel containing chromium – resulting in a moderately high score for CSP plants, which require significant amounts of steel in the infrastructure of the plant. solar fields compared to the electricity produced.

Global-installed-capacity

Technologies: Nuclear energy

About 70 SMR designs are in development today. There is no strict definition of SMRs, but in practice they include reactors of less than 300 MW, as well as a high degree of modularity, for example, whole reactors can be designed to be transported by truck and installed at any site with minimal preparation. This flexibility theoretically reduces construction and upscaling time. Some designs can also follow the load, more efficiently than conventional nuclear power plants, making SMRs attractive when it comes to grid integration challenges. Overall, the development of SMRs provides access to nuclear power to countries that cannot accommodate large nuclear power plants for various reasons, be it cost or energy policy planning. It is recognized that the commercial deployment of SMRs would unlock access to nuclear power in new sectors and regions.

Environmental impact assessment

A life cycle assessment of the NuScale The SMR (Godsey, K., Life Cycle Assessment of Small Modular Reactors Using US Nuclear Fuel Cycle. 2019, Clemson University) design reveals that per kWh of power generation, the system would emit 4.6 g of CO2 eq / kWh. This figure is significantly lower than the previously reported value (Carless, TS, WM Griffin and PS Fischbeck, The Environmental Competitiveness of Small Modular Reactors: A life cycle study. Energy, 2016), of 8.4 g CO2 eq./kWh. As both reactors are smaller versions of conventional light water reactors, this range of emissions coincides with commonly reported life cycle GHG emissions from reactors at the 1000 MW scale, including the value in this report. , 5.6 g CO2 eq./kWh under European (core and backend) conditions.

Main conclusions

The primary objective of this report is to assess the environmental impacts of the life cycle of power generation options. This was achieved by performing an LCA on the updated life cycle inventories of certain technologies.

More specifically, hard coal, natural gas, hydroelectricity, concentrated solar power, photovoltaics, wind power and nuclear power were assessed with regard to the following indicators: climate change, eutrophication of fresh water, ionizing radiation, toxicity human, land use, dissipated water, as well as the use of resources.

Regarding GHG emissions, coal energy shows the highest scores, with a minimum of 751 g CO2 eq./kWh (IGCC, USA) and a maximum of 1095 g CO2 eq./kWh (coal sprayed, China). Equipped with a carbon dioxide capture installation, and taking into account the storage of CO2, this score can drop to 147-469 g CO2 eq./kWh (respectively). A combined cycle natural gas plant can emit 403 to 513 g CO2 eq./kWh from a lifecycle point of view, and between 49 and 220 g CO2 eq./kWh with CCS. Nuclear power shows less variability due to the limited regionalization of the model, with 5.1 to 6.4 g CO2 eq./kWh. Regarding renewable energies, hydropower shows the greatest variability, as emissions are very site-specific, ranging from 6 to 147 g CO2 eq./kWh. Since biogenic emissions from sediment accumulated in reservoirs are mostly excluded, it should be noted that they can be very high in tropical areas. Solar technologies present GHG emissions ranging from 27 to 122 g of eq. CO2 / kWh for the CSP and from 8.0 to 83 g of eq. of CO2 / kWh for photovoltaics, for which thin-film technologies are significantly lower in carbon than silicon-based PV. The upper range of GHG values ​​for CSP is probably never achieved in reality as it requires high solar irradiation to be economically viable (a condition that is not met in Japan or Northern Europe, for example) . Greenhouse gas emissions from wind power range between 7.8 and 16 g eq. CO2 / kWh for the onshore, and between 12 and 23 g eq. CO2 / kWh for offshore wind turbines.

Most of the GHG emissions from renewable technologies are incorporated into infrastructure (up to 99% for photovoltaics), which suggests strong variations in life cycle impacts due to variations in the origin of raw materials, energy mix used for production, modes of transport at the various stages of manufacture and assembly, etc.

All technologies show very little eutrophication of freshwater during their life cycle, with the exception of coal, the extraction of which generates residues that leach the phosphate into rivers and groundwater. CCS does not influence these emissions because they occur during the extraction phase. Average P emissions from coal range from 600 to 800 g P eq / MWh, which means that phasing out coal would virtually reduce eutrophic emissions by a factor of 10 (if replaced by PV) or 100 (if replaced by wind, hydroelectricity or nuclear).

Several areas of the United States are at risk of widespread power outages if extreme weather conditions strike this winter, according to an assessment by the nonprofit North American Reliability Corporation. Texas, which generates more electricity than any other state, could see many power plants. become inoperative with the right winter storm, causing demand for electricity to exceed by up to 37% what is being generated, according to the report. That means nearly half of the state’s electrical resources would not be able to meet customer demand, leaving millions of Texans in the dark – again. The sobering outlook comes after record high temperatures in February 2021 brought the state to its highest electricity demand on record as residents tried to warm up. power outages just when Texans needed power the most. More than 200 people died during the electricity crisis, the most common cause of death being the rmia hypothesis. A post-storm analysis released in November indicated that power plants were unable to generate electricity mainly due to natural gas issues and generator freezes. the events of last winter underline the need to air-condition critical infrastructures. “Extreme weather events, like that of February 2021, are unfortunately becoming more and more common and the power ecosystem must come together to plan and prepare to operate in more extreme conditions, longer duration and extended weather events.” NERC Chairman Jim Robb said. The central and northern plains could also be on the verge of having power shortages this season under extreme conditions. The ongoing drought in the west has taken a toll. many hydroelectric plants. And researchers predict that the Northwest’s energy reserves could drop as much as -1.5% in a record storm. NERC also warns that on-site fuel stocks for the plants electricity are below normal for this time of year. While this is not a problem at the moment, the ongoing energy crisis overseas and the supply chain rumbling viewing make it a topic to watch out for. The winter weather outlook is at least optimistic. average temperatures over much of the southeast and northeast from December to February. Temperatures in the southwest, southern and central plains, as well as the Ohio River Valley and the central Atlantic are expected to be slightly above normal. Meanwhile, the Pacific Northwest and the northern Rockies are expected to experience cooler than normal temperatures. But it’s important to remember that while the winter is warmer than normal for much of the country, spells of extreme cold can still occur at times. Look no further than last winter, when the southern plains witnessed a record deep freeze despite the expectation of above-average temperatures. In particular, Texas broke many records and cold temperatures crippled the power grid. Last winter saw the weather effects of a La Niña. And a National Oceanic and Atmospheric Administration forecast was in line with typical La Niña expectations: cooler, wetter weather in the northern United States and drier, warmer-than-average temperatures in much of the region. southern United States. – January was the least La Niña-like pattern of the 13 moderate to strong La Niña from 1950. Why? Who knows ! But the influence of chaotic weather variability is still there. Yes, even during a La Niña, Mother Nature can just BE that way sometimes, ”meteorologist Tom Di Liberto wrote in March in a NOAA blog post.

Several areas of the United States are at risk of widespread power outages if extreme weather conditions strike this winter, according to a Evaluation by the non-profit North American Reliability Corporation.

Texas, which generates more electricity than any other state, could see many power plants go inoperative with the right winter storm, causing demand for electricity to exceed what is generated by up to 37%, according to the report.

That means nearly half of the state’s electrical resources would not be able to meet customer demand, again leaving millions of Texans in the dark.

The sobering outlook comes after record high temperatures in February 2021 brought the state to its highest electricity demand on record as residents tried to warm up.

To prevent the power grid from warping under stress, grid operators were forced to implement service outages when Texans needed electricity the most.

More … than 200 people died during the electricity crisis, the most common cause of death being hypothermia.

A post-storm analysis published in November said power plants were unable to generate electricity, mainly due to natural gas issues and freezing generators.

NERC, which regulates the bulk power system for all of the United States (including Texas) and Canada, says the events of last winter underscore the need for air conditioning critical infrastructure.

“Extreme weather events, such as that of February 2021, are unfortunately becoming more and more common and the electrical ecosystem must come together to plan and prepare to operate under more extreme, longer and more extensive weather events,” Jim , president of NERC. Robb said.

February outages could have been reduced by 67% in Texas simply by weathering four types of power plant components, according to the NERC analysis.

High risks outside of Texas

Other power markets in the central and northern plains could also experience power shortages this season under extreme conditions.

The drought in the west has affected many hydroelectric plants. And researchers predict the Northwest’s energy reserves could drop as much as -1.5% during a record storm.

NERC is also warning that on-site fuel stocks for power plants are below normal for this time of year. While not a problem at the moment, the ongoing energy crisis overseas and the supply chain make it a topic to watch.

Winter weather forecasts are at least optimistic

The NERC assessment coincides with the Climate Prediction Center winter weather forecast.

The CPC expects above average temperatures over much of the southeast and northeast from December through February. Temperatures in the southwest, southern and central plains, as well as the Ohio River valley and the central Atlantic are expected to be slightly above normal.

Meanwhile, the Pacific Northwest and northern Rockies are expected to experience cooler-than-normal temperatures.

But it’s important to remember that while it’s a warmer than normal winter for much of the country, extreme cold spells can still occur at times.

Look no further than last winter, when the southern plains witnessed a record deep freeze despite expectations of above-average temperatures. In particular, Texas broke many records and cold temperatures crippled the power grid.

Last winter saw the weather effects of a La Niña. And a National Oceanic and Atmospheric Administration forecast was in line with typical La Niña expectations: cooler, wetter weather in the northern United States and drier, warmer-than-average temperatures in much of the region. southern United States.

“In fact, last December-January this was the least La Niña-like pattern of the 13 moderate to strong La Niña dating back to 1950. Why? Who knows! But the influence of chaotic weather variability is still there. Yes, even during a La Niña, Mother Nature can sometimes BE like this, ”meteorologist Tom Di Liberto wrote in March in a NOAA blog post.

In a media advisory, the Tanzania Electric Supply Co. (TANESCO) said yesterday that the ongoing drought across the country is threatening power generation at hydropower plants, noting that the depletion of water in dams has affected power generation at Kihansi, Kidatu and Pangani power plants.

The company was thus preparing to increase the production of electricity from natural gas, by accelerating the maintenance of some of its plants, including Ubungo I with a capacity of 25 MW, Kinyerezi I with 185 MW and Ubungo III with a power of 112 MW at full speed, said the firm. .

The company is also looking forward to launching the 36 MW power station at Nyakato Power Plant, adding a total of 358 MW to the power available for the national grid, he said.

Power cuts are expected in various regions, in which case the company will release information in a timely manner so that customers can properly plan their activities, the notice intoned, regretting the inconvenience caused by the ongoing power outages. .

Routine power generation data places the country’s capacity at 1,605 MW where the contribution from gas exceeds 900 MW, hydropower 508 MW and renewables around 58 MW input, but some projections claim that d ‘By 2023, out of 550 MW of new energy input generated by the private sector, private sector sources will represent 400 MW. and the 150 MW public sector, with the parastatal expecting a new 600 MW entry by 2025.

Hydropower generation is one of the main sources of electricity today, but the main rivers feeding major dams have low water levels due to a prolonged dry season.

Last week, TANESCO Director General Maharage Chande said there was no power rationing yet, but intermittent blackouts and early morning power cuts in the city of Dar es Salaam are commonplace.

Maintenance of transformers is often reported as causing power interruptions.

A fortnight ago, Energy Minister January Makamba scrambled to explain on social media what sustainable solutions are available for endless blackouts.

New electricity project in WA takes a turn on hydropower https://waterky.org/new-electricity-project-in-wa-takes-a-turn-on-hydropower/ https://waterky.org/new-electricity-project-in-wa-takes-a-turn-on-hydropower/#respond Wed, 10 Nov 2021 13:03:17 +0000 https://waterky.org/new-electricity-project-in-wa-takes-a-turn-on-hydropower/ In an Oct. 6 press release from the Yakama Nation, tribal chiefs explained that this area is known to tribal members as “Pushpum,” a sacred site for ceremonies, legends and root gathering. and medicine for many generations, George Selam, said the chairman of the tribal council’s cultural committee in the press release. “For generations, regional […]]]>

In an Oct. 6 press release from the Yakama Nation, tribal chiefs explained that this area is known to tribal members as “Pushpum,” a sacred site for ceremonies, legends and root gathering. and medicine for many generations, George Selam, said the chairman of the tribal council’s cultural committee in the press release.

“For generations, regional utility infrastructure has been developed in Yakama Nation Treaty territory, blowing up customary fishing grounds, inundating traditional villages and infiltrating (Hanford’s) radioactive pollution into root fields. medicines and subsistence, ”said Jeremy Takala, municipal councilor of the Yakama tribe, in the Liberation.

Tribal Council Vice Chairman Virgil Lewis said he expects the Pacific Northwest to come under pressure from the energy industry over the next decade. to allow further development of infrastructure.

“This new technology must be developed ethically without destroying the cultural resources and gathering sites that are part of the Yakama way of life,” Lewis said.

Columbia Riverkeeper, the Washington chapter of the Sierra Club, American Rivers and the Washington Environmental Council joined the Yakamas in opposing the project. A coalition of 15 environmental groups wrote a letter to elected officials of the state that In Washington and Oregon to oppose the project.

“Greenwashing ends today,” said Simone Anter, staff attorney for Columbia Riverkeeper. “Rye’s proposal would have devastating effects on tribal nations and indigenous peoples. The project also threatens local wildlife such as the bald eagle and the royal eagle. We call on the leaders of the Northwest to honor the treaty rights of tribal nations and oppose this short-sighted enterprise.

Recently, the Yakama Nation has expressed concerns more frequently about renewable energy projects appearing on surrendered lands in Klickitat County, McClure said.

Steimle said Rye Development is keen to work closely with the Yakama Nation and uphold their values. The company and the Yakamas have started discussions on the subject.

Rye Development is the first company to pursue the concept of pumped storage in the Pacific Northwest. In addition to the Klickitat County project, Rye Development is developing a similar 400 megawatt pumped storage project at Swan Lake in southern Oregon. This $ 800 million project is expected to go live in 2026.

The Klickitat and Swan Lake projects are Rye Development’s first pump storage ventures. The company has 22 projects east of the Mississippi River that involve converting unpowered dams to hydroelectric dams.

The Klickitat project is halfway through a review of the state’s environmental policy law and is progressing towards a permit from the Federal Energy Regulatory Commission. In June, the Washington Department of Ecology rejected Rye Development’s application for a water quality permit due to insufficient information. But the state allows the company to resubmit the request.

The Klickitat project still faces two environmental obstacles.

One is the old aluminum smelter at the lower reservoir site which various companies operated from 1969 to 2003. Smelter operations contaminated the site’s soil and groundwater with fluoride, polycyclic aromatic hydrocarbons. , cyanide and polychlorinated biphenyls. Rye’s development plans would deal with this pollution, which Steimle says will cost around $ 10 million.

The second hurdle is noted by the Washington Department of Fish and Wildlife in its comments on Rye Development’s state permit application. Bald and royal eagles fly in Klickitat County. Written comments from the Department of Wildlife indicated that the upper reservoir would attract thirsty eagles to an area filled with wind turbines with rotating blades that could prove fatal to some birds.

Mathura: The government of Uttar Pradesh has launched an interest relief program for electricity consumers on their overdue bills, said State Energy Minister for Srikant Sharma. “Under this program, default interest would be waived for certain categories of consumers,” Sharma, UP Minister of Energy and Additional Energy Sources, told reporters.

He said the money made would pave the way for improvements as the department is already running a deficit of Rs 90,000 crore.

The loan waiver program was introduced because about 70% of rural consumers are unable to deposit their bills on time, while 25% of urban consumers have become delinquent due to not paying bills on time, a declared the minister.

He added that prompt payment of bills by all would pave the way for uninterrupted and inexpensive power supply.

In this regard, the default interest has not only been removed, but the option to pay arrears in six easy installments has also been extended to domestic consumers, the minister said.

According to the minister, for the first time, commercial consumers have been subjected to the regime. Respite was also offered to small businesses affected by the COVID-19 pandemic.

The interest on arrears of traders for the consumption category of less than two kilowatts has been waived, while the 50% interest on the arrears of traders in the 2 to 5 kilowatt category will be waived, the minister said.

The aim of introducing this program is to fulfill the government’s commitment to provide inexpensive and uninterrupted power supply, the minister said.
