The State Grid Corporation of China (SGC) (Beijing) has decided to invest $340 million this year to improve the Hunan power grid's ability to withstand ice, according to Hunan Electric Power Company (Changsha), a subsidiary of SGC in Hunan Province.

From mid-January to mid-February of this year, the grid was greatly affected by the severe snowstorms that hit the country. The grid's transmission lines were encased in ice about 70 millimeters to 90 millimeters thick; the lines' designed limit was 15 millimeters to 20 millimeters.

The $340 million upgrade will cover six transmission lines with a total length of 531 kilometers and 38 crossovers at the 500-kilovolt (kV) level; 20 transmission lines with a total length of 733 kilometers and 38 crossovers at the 220 kV level; and 26 transmission lines with a total length of 452 kilometers and 165 crossovers at the 110 kV level.

Related departments of the SGC have been planning for various stages of the project, including tendering and construction. During construction, new technologies, new materials and new processes will be used. For instance, the application of multi-circuit, compact and narrow foundation steel pipe assembled towers will be adopted in 220 kV and 110 kV transmission lines.

In a record year for clean energy purchases, Southeast cities stand out

Municipal Renewable Energy Procurement surged as cities contracted 3.7 GW of solar and wind, leveraging green tariffs, community solar, and utility partnerships across the Southeast, led by Houston, RMI, and WRI data.

 

Key Points

The process by which cities contract solar and wind via utilities or green tariffs to meet climate goals.

✅ 3.7 GW procured in 2020, nearly 25% year-over-year growth

✅ Houston runs city ops on 500 MW solar, a record purchase

✅ Southeast cities use green tariffs and community solar

 

Cities around the country bought more renewable energy last year than ever before, reflecting how renewables may soon provide one-fourth of U.S. electricity across the grid, with some of the most remarkable projects in the Southeast, according to new data unveiled Thursday.

Even amid the pandemic, about eight dozen municipalities contracted to buy nearly 3.7 gigawatts of mostly solar and wind energy — enough to power more than 800,000 homes. The figure is almost a quarter higher than the year before.

Half of the cites listed as “most noteworthy” in Thursday’s release —  from research groups Rocky Mountain Institute and World Resources Institute — are in the region that stretches from Texas to Washington, D.C. 

Houston stands out for the sheer enormity of its purchase: In July, it began powering city operations entirely from nearly 500 megawatts of solar power — the largest municipal purchase of renewable energy ever in the United States, as renewable electricity surpassed coal nationwide.

The groups also feature smaller deals in North Carolina and Tennessee, achieved through a utility partnership called a green tariff.

“We wanted to recognize that Nashville and Charlotte were really blazing a new trail,” said Stephen Abbott, principal at the Rocky Mountain Institute.

And the nation’s capital shows how renewable energy can be a source of revenue: It’s leasing out its public transit station rooftops for 10 megawatts of community solar.

All of these strategies will be necessary for scores of U.S. cities to meet their ambitious climate goals, researchers believe. An interactive clean energy targets tracker shows all 95 clean energy procurements from the year in detail.


Tracker 
Even before former President Donald Trump promised to remove the United States from the Paris Climate Accord, a lack of federal action on climate left a void that some cities and counties were beginning to fill, as renewables hit a record 28% in a recent month. In 2015, the first year tracked by researchers at the Rocky Mountain Institute and the World Resources Institute, municipalities contracted to buy more than 1 gigawatt of wind, solar and other forms of clean energy. 

But when Trump officially set in motion the withdrawal from the climate agreement, the ranks of municipalities dedicated to 100% clean energy multiplied. Today there are nearly 200 of them. The growth in activity last year reflects, in part, that surge of new pledges.

“It takes a while to get city staff up to speed and understand the options, and create the roadmap and then start executing,” Abbott said. “There is a bit of a lag, but we’re starting to see the impact.”

Even in Houston — one of the earliest to begin procuring renewable energy — there has been a steep learning curve as market forces change and prices drop, including cheaper solar batteries shaping procurement strategies, said Lara Cottingham, Houston’s chief of staff and chief sustainability officer.

No matter how well resourced and educated their staff, cities have to clear a thicket of structural, political and economic challenges to procure renewable energy. Most don’t own their own sources of power. Nearly all face budget constraints. Few have enough land or government rooftops to meet their goals within city limits.

“Cities face a situation where it’s a square peg in a round hole,” Cottingham said.

The hurdles are especially steep in much of the Southeast, where only publicly regulated utilities can sell electricity to retail customers, even large ones such as major cities. That’s where a green tariff regime comes in: Cities can purchase clean energy from a third party, such as a solar company, using the utility as a go-between.

Early last year, Charlotte became the largest city to use such a program, partnering with Duke Energy and two North Carolina solar developers to build a solar farm 50 miles north in Iredell County. At first, the city will pay a premium for the energy, but in the latter half of the 20-year contract, as gas prices rise, it will save money compared to business as usual.

“Over the course of 20 years, it’s projected we would save about $2 million,” Katie Riddle, sustainability analyst with Charlotte, told the Energy News Network last year.

The growing size of projects, innovative partnerships like green tariff programs, and the improving economics all give Abbott hope that renewable energy investments from cities will only grow — even with the Trump presidency over and the country back in the Paris agreement.

And when cities meet their goals for procuring renewable energy for their own operations, they must then turn to an even bigger task: reducing the carbon footprint of every person in their jurisdiction with broader decarbonization strategies and community engagement.

“The city needs to do its part for sure,” said Houston’s Cottingham. “Then we have this challenge of how do we get everyone else to.”

Manitoba looking to raise electricity rates 2.5 per cent each year for 3 years

Manitoba Hydro Rate Increase sets electricity rates up 2.5% annually for three years via Bill 35, bypassing PUB hearings, citing Crown utility debt and pandemic impacts, with legislature debate and a multi-year regulatory review ahead.

 

Key Points

A government plan to lift electricity rates 2.5% annually over three years via Bill 35, bypassing PUB hearings.

✅ 2.5% annual hikes for three years set in legislation

✅ Bypasses PUB rate hearings during pandemic recovery

✅ Targets Crown utility debt; multi-year review planned

 

The Manitoba government is planning to raise electricity rates, with Manitoba Hydro scaling back next year, by 2.5 per cent a year over the next three years.

Finance Minister Scott Fielding says the increases, to be presented in a bill before the legislature, are the lowest in a decade and will help keep rates among the lowest in Canada, even as SaskPower's 8% hike draws scrutiny in a neighbouring province.

Crown-owned Manitoba Hydro had asked for a 3.5 per cent increase this year, similar to BC Hydro's 3% rise, to help pay off billions of dollars in debt.

“The way we figured this out, we looked at the rate increases that were approved by PUB (Public Utilities Board) over the last ten years, (and) we went to 75 per cent of that,” Fielding said during a Thursday morning press conference.

“It’s a pandemic, we know that there’s a lot of people that are unemployed, that are struggling, we know that businesses need to recharge after the business (sic), so this will provide them an appropriate break.”

Electricity rates are normally set by the Public Utilities Board, a regulatory body that holds rate hearings and examines the Crown corporation’s finances.

The Progressive Conservative government has temporarily suspended the regulatory process and has set rates itself, while Ontario rate legislation to lower rates moved forward in its jurisdiction.

Manitoba Liberal leader Dougald Lamont was quick to condemn the move, noting parallels to Ontario price concerns before saying in a news release the PCs “are abusing their power and putting Hydro’s financial future at risk by fixing prices in the hope of buying some political popularity.”

“Hydro’s rates should be set by the PUB after public hearings, not figured out on the back of a napkin in the Premier’s office,” Lamont wrote.

Fielding noted the increase would appear as an amendment to Bill 35, which will appear in the legislature this fall, as BC Hydro plans multi-year increases proceed elsewhere.

“All members of the legislative assembly will vote and debate this rate increase on Bill 35,” Fielding said.

“This will give the PUB time to implement reforms, and allow the utilities to prepare a more rigorous, multi-year review application process.”

US Dept. of Energy awards Washington state $23.4 million to strengthen infrastructure

Washington Grid Resilience Grant funds DOE-backed modernization to harden Washington's electric grid against extreme weather, advancing clean energy, affordable and reliable electricity, and community resilience under the Bipartisan Infrastructure Law via projects and utility partnerships.

 

Key Points

A $23.4M DOE grant to modernize Washington's grid, boost weather resilience, and deliver clean, reliable power.

✅ Targets outages, reliability, and community resilience statewide.

✅ Prioritizes disadvantaged areas and quality clean energy jobs.

✅ Backed by Bipartisan Infrastructure Law and DOE funding.

 

Washington state has received a $23.4 million Grid Resilience State and Tribal Formula Grant from the U.S. Department of Energy (DOE) to modernize the electric grid through smarter electricity infrastructure and reduce impacts due to extreme weather and natural disasters. Grid Resilience State and Tribal Formula Grants aim to ensure the reliability of power sector infrastructure so that communities have access to affordable, reliable, clean electricity.

“Electricity is an essential lifeline for communities. Improving our systems by reducing disruptive events is key as we cross the finish line of a 100% clean electricity grid and ensure equitable benefits from the clean energy economy reach every community,” said Gov. Jay Inslee.

The federal funding for energy resilience will enhance and expand ongoing current grid modernization and resilience efforts throughout the state. For example, working directly with rural and typical end-of-the-line customers to develop resilience plans and collaborating with communities and utilities, including smart city efforts in Spokane as examples, on building resilient and renewable infrastructure for essential services.

“This is a significant opportunity to supplement our state investments in building a robust, resilient electric grid that supports our long-term vision for clean, affordable and reliable electricity – the foundation for economic growth and job creation that strengthens our communities and keeps Washington globally competitive. It shows once again that we are maximizing the federal funding being made available by the Biden-Harris Administration to invest in the country’s infrastructure,” said Washington State Department of Commerce Director Mike Fong.

Across the border, British Columbia's clean energy shift adds regional momentum for resilient, low-carbon power.

Goals include:

Reducing the frequency, duration and impact of outages as climate change impacts on the grid intensify while enhancing resiliency in historically disadvantaged communities.
Strengthening prosperity by expanding well-paying, safe clean energy jobs accessible to all workers and ensuring investments have a positive effect on quality job creation and equitable economic development.

Building a community of practice and maximizing project scalability by identifying pathways for scaling innovations such as integrating solar into the grid across programs.

“The Grid Resilience Formula Grants will enable communities in Washington to protect households and businesses from blackouts or power shutdowns during extreme weather,” said Maria Robinson, Director, Grid Deployment Office, U.S. Department of Energy. “Projects selected through this program will benefit communities by creating good-paying jobs to deliver clean, affordable, and reliable energy across the country.”

DOE has also announced $34 million for grid improvements to bolster reliability nationwide.

“An innovative, reliable, and efficient power grid is vital to Washington’s continued economic growth and for community resilience especially in disadvantaged areas,” said U.S. Rep. Strickland, Co-Lead of the bipartisan Grid Innovation Caucus. “The funding announced today will invest in our energy grid, support good-paying jobs, and means a cleaner, more energy-efficient future.”

Funded through the Bipartisan Infrastructure Law and administered by DOE’s Grid Deployment Office, with related efforts such as California grid upgrades advancing nationwide, the Grid Resilience State and Tribal Formula Grants distribute funding to states, territories, and federally recognized Indian Tribes, over five years based on a formula that includes factors such as population size, land area, probability and severity of disruptive events, and a locality’s historical expenditures on mitigation efforts. Priority will be given to projects that generate the greatest community benefit providing clean, affordable, and reliable energy.

PG&E Rates Set to Stabilize in 2025

PG&E 2024 Rate Hikes signal sharp increases to fund wildfire safety, infrastructure upgrades, and CPUC-backed reliability, with rates expected to stabilize in 2025, affecting rural residents, businesses, and high-risk zones across California.

 

Key Points

PG&E’s 2024 hikes fund wildfire safety and grid upgrades, with pricing expected to stabilize in 2025.

✅ Driven by wildfire safety, infrastructure, and reinsurance costs

✅ Largest impacts in rural, high-risk zones; business rates vary

✅ CPUC oversight aims to ensure necessary, justified investments

 

Pacific Gas and Electric (PG&E) is expected to implement a series of rate hikes that, amid analyses of why California electricity prices are soaring across the state, will significantly impact California residents. These increases, while substantial, are anticipated to be followed by a period of stabilization in 2025, offering a sense of relief to customers facing rising costs.

PG&E, one of the largest utility providers in the state, announced that its 2024 rate hikes are part of efforts to address increasing operational costs, including those related to wildfire safety, infrastructure upgrades, and regulatory requirements. As California continues to face climate-related challenges like wildfires, utilities like PG&E are being forced to adjust their financial models to manage the evolving risks. Wildfire-related liabilities, which have plagued PG&E in recent years, play a significant role in these rate adjustments. In response to previous fire-related lawsuits, including a bankruptcy plan supported by wildfire victims that reshaped liabilities, and the increased cost of reinsurance, PG&E has made it clear that customers will bear part of the financial burden.

These rate hikes will have a multi-faceted impact. Residential users, particularly those in rural or high-risk wildfire zones, will see some of the largest increases. Business customers will also be affected, although the adjustments may vary depending on the size and energy consumption patterns of each business. PG&E has indicated that the increases are necessary to secure the utility’s financial stability while continuing to deliver reliable service to its customers.

Despite the steep increases in 2024, PG&E's executives have assured that the company's pricing structure will stabilize in 2025. The utility has taken steps to balance the financial needs of the business with the reality of consumer affordability. While some rate hikes are inevitable given California's regulatory landscape and climate concerns, PG&E's leadership believes the worst of the increases will be seen next year.

PG&E’s anticipated stabilization comes after a year of scrutiny from California regulators. The California Public Utilities Commission (CPUC) has been working closely with PG&E to scrutinize its rate request and ensure that hikes are justifiable and used for necessary investments in infrastructure and safety improvements. The CPUC’s oversight is especially crucial given the company’s history of safety violations and the public outrage over past wildfire incidents, including reports that its power lines may have sparked fires in California, which have been linked to PG&E’s equipment.

The hikes, though significant, reflect the broader pressures facing utilities in California, where extreme weather patterns are becoming more frequent and intense due to climate change. Wildfires, which have grown in severity and frequency in recent years, have forced PG&E to invest heavily in fire prevention and mitigation strategies, including compliance with a judge-ordered use of dividends for wildfire mitigation across its service area. This includes upgrading equipment, inspecting power lines, and implementing more rigorous protocols to prevent accidents that could spark devastating fires. These investments come at a steep cost, which PG&E is passing along to consumers through higher rates.

For homeowners and businesses, the potential for future rate stabilization offers a glimmer of hope. However, the 2024 increases are still expected to hit consumers hard, especially those already struggling with high living costs. The steep hikes have prompted public outcry, with calls for action as bills soar amplifying advocacy group arguments that utilities should absorb more of the costs related to climate change and fire prevention instead of relying on ratepayers.

Looking ahead to 2025, the expectation is that PG&E’s rates will stabilize, but the question remains whether they will return to pre-2024 levels or continue to rise at a slower rate. Experts note that California’s energy market remains volatile, and while the rates may stabilize in the short term, long-term cost management will depend on ongoing investments in renewable energy sources and continued efforts to make the grid more resilient to climate-related risks.

As PG&E navigates this challenging period, the company’s commitment to transparency and working with regulators will be crucial in rebuilding trust with its customers. While the immediate future may be financially painful for many, the hope is that the utility's focus on safety and infrastructure will lead to greater long-term stability and fewer dramatic rate increases in the years to come.

Ultimately, California residents will need to brace for another tough year in terms of utility costs but can find reassurance that PG&E’s rate increases will eventually stabilize. For those seeking relief, there are ongoing discussions about increasing energy efficiency, exploring renewable energy alternatives, and expanding assistance programs for lower-income households to help mitigate the financial strain of these price hikes.

Tesla updates Supercharger billing to add cost of electricity use for other than charging

Tesla Supercharger Billing Update details kWh-based pricing that now includes HVAC, battery thermal management, and other HV loads during charging sessions, improving cost transparency across pay-per-use markets and extreme climate scenarios.

 

Key Points

Tesla's update bills for kWh used by HVAC, battery heating, and HV loads during charging, reflecting true energy costs.

✅ kWh charges now include HVAC and battery thermal management

✅ Expect 10-25 kWh increases in extreme climates during sessions

✅ Some regions still bill per minute due to regulations

 

Tesla has updated its Supercharger billing policy to add the cost of electricity use for things other than charging, like HVAC, battery thermal management, etc, while charging at a Supercharger station, a shift that impacts overall EV charging costs for drivers. 

For a long time, Tesla’s Superchargers were free to use, or rather the use was included in the price of its vehicles. But the automaker has been moving to a pay-to-use model over the last two years in order to finance the growth of the charging network amid the Biden-era charging expansion in the United States.

Not charging owners for the electricity enabled Tesla to wait on developing a payment system for its Supercharger network.

It didn’t need one for the first five years of the network, and now the automaker has been fine-tuning its approach to charge owners for the electricity they consume as part of building better charging networks across markets.

At first, it meant fluctuating prices, and now Tesla is also adjusting how it calculates the total power consumption.

Last weekend, Tesla sent a memo to its staff to inform them that they are updating the calculation used to bill Supercharging sessions in order to take into account all the electricity used:

The calculation used to bill for Supercharging has been updated. Owners will also be billed for kWhs consumed by the car going toward the HVAC system, battery heater, and other HV loads during the session. Previously, owners were only billed for the energy used to charge the battery during the charging session.

Tesla says that the new method should more “accurately reflect the value delivered to the customer and the cost incurred by Tesla,” which mirrors recent moves in its solar and home battery pricing strategy as well.

The automaker says that customers in “extreme climates” could see a difference of 10 to 25 kWh for the energy consumed during a charging session:

Owners may see a noticeable increase in billed kWh if they are using energy-consuming features while charging, e.g., air conditioning, heating etc. This is more likely in extreme climates and could be a 10-25 kWh difference from what a customer experienced previously, as states like California explore grid-stability uses for EVs during peak events.

Of course, this is applicable where Tesla is able to charge by the kWh for charging sessions. In some markets, regulations push Tesla to charge by the minute amid ongoing fights over charging control between utilities and private operators.

Electrek’s Take
It actually looks like an oversight from Tesla in the first place. It’s fair to charge for the total electricity used during a session, and not just what was used to charge your battery pack, since Tesla is paying for both, even as some states add EV ownership fees like the Texas EV fee that further shape costs.

However, I wish Tesla would have a clearer way to break down the charging sessions and their costs.

There have been some complaints about Tesla wrongly billing owners for charging sessions, and this is bound to create more confusion if people see a difference between the kWhs gained during charging and what is shown on the bill.

B.C. Challenges Alberta's Electricity Export Restrictions

BC-Alberta Electricity Restrictions spotlight interprovincial energy tensions, limiting power exports and affecting grid reliability, energy sharing, and climate goals, while raising questions about federal-provincial coordination, smart grids, and storage investments.

 

Key Points

Policies limiting Alberta's power exports to provinces like BC, prioritizing local demand and affecting grid reliability.

✅ Prioritizes Alberta load over interprovincial power exports

✅ Risks to BC peak demand support and outage resilience

✅ Pressures for federal-provincial coordination and smart-grid investment

 

In a move that underscores the complexities of Canada's interprovincial energy relationships, the government of British Columbia (B.C.) has formally expressed concerns over recent electricity restrictions imposed by Alberta after it suspended electricity purchase talks with B.C., amid ongoing regional coordination challenges.

Background: Alberta's Electricity Restrictions

Alberta, traditionally reliant on coal and natural gas for electricity generation, has been undergoing a transition towards more sustainable energy sources as it pursues a path to clean electricity in the province.

In response, Alberta introduced restrictions on electricity exports, aiming to prioritize local consumption and stabilize its energy market and has proposed electricity market changes to address structural issues.

B.C.'s Position: Ensuring Energy Reliability and Cooperation

British Columbia, with its diverse energy portfolio and commitment to sustainability, has historically relied on the ability to import electricity from Alberta, especially during periods of high demand or unforeseen shortfalls. The recent restrictions threaten this reliability, prompting B.C.'s government to take action amid an electricity market reshuffle now underway.

B.C. officials have articulated that access to Alberta's electricity is crucial, particularly during outages or times when local generation does not meet demand. The ability to share electricity among provinces ensures a stable and resilient energy system, benefiting consumers and supporting economic activities, including critical minerals operations, that depend on consistent power supply.

Moreover, B.C. has expressed concerns that Alberta's restrictions could set a precedent that might affect future interprovincial energy agreements. Such a precedent could complicate collaborative efforts aimed at achieving national energy goals, including sustainability targets and infrastructure development.

Broader Implications: National Energy Strategy and Climate Goals

The dispute between B.C. and Alberta over electricity exports highlights the absence of a cohesive national energy strategy, as external pressures, including electricity exports at risk, add complexity. While provinces have jurisdiction over their energy resources, the interconnected nature of Canada's power grids necessitates coordinated policies that balance local priorities with national interests.

This situation also underscores the challenges Canada faces in meeting its climate objectives. Transitioning to renewable energy sources requires not only technological innovation but also collaborative policies that ensure energy reliability and affordability across provincial boundaries, as rising electricity prices in Alberta demonstrate.

Potential Path Forward: Dialogue and Negotiation

Addressing the concerns arising from Alberta's electricity restrictions requires a nuanced approach that considers the interests of all stakeholders. Open dialogue between provincial governments is essential to identify solutions that uphold the principles of energy reliability, economic cooperation, and environmental sustainability.

One potential avenue is the establishment of a federal-provincial task force dedicated to energy coordination. Such a body could facilitate discussions on resource sharing, infrastructure investments, and policy harmonization, aiming to prevent conflicts and promote mutual benefits.

Additionally, exploring technological solutions, such as smart grids and energy storage systems, could enhance the flexibility and resilience of interprovincial energy exchanges. Investments in these technologies may reduce the dependency on traditional export mechanisms, offering more dynamic and responsive energy management strategies.

The tensions between British Columbia and Alberta over electricity restrictions serve as a microcosm of the broader challenges facing Canada's energy sector. Balancing provincial autonomy with national interests, ensuring equitable access to energy resources, and achieving climate goals require collaborative efforts and innovative solutions. As the situation develops, stakeholders across the political, economic, and environmental spectrums will need to engage constructively, fostering a Canadian energy landscape that is resilient, sustainable, and inclusive.
