Sunrun-Tesla Virtual Power Plant Texas leverages residential solar, Tesla Powerwall battery storage, and ERCOT demand response to enhance grid resilience, cut emissions, and supply backup power via a coordinated distributed energy resources network.

Key Points

A Texas VPP using residential solar and Tesla Powerwall to aid ERCOT with grid services resilience, and less emissions.

✅ Aggregates Powerwall storage for ERCOT demand response.

✅ Enhances grid reliability with distributed energy resources.

✅ Cuts emissions by shifting solar to peak and outage periods.

In a significant development for renewable energy and grid resilience, Sunrun and Tesla have announced a groundbreaking partnership to establish a distributed power plant in Texas. This collaboration represents a major step forward in harnessing solar energy and battery storage, with advances in affordable solar batteries helping to create a more reliable and sustainable power system. The initiative aims to address the growing demand for clean energy solutions while enhancing grid stability and resilience in one of the largest and most energy-dependent states in the U.S.

The new distributed power plant, a joint venture between Sunrun, a leading residential solar provider, and Tesla, renowned for its advanced battery technology and electric vehicles, will leverage the strengths of both companies to transform how energy is generated and used. The project will deploy Tesla's Powerwall battery systems alongside Sunrun's solar panels to create a network of interconnected residential energy storage units. This network will function as a virtual power plant, aligned with emerging peer-to-peer energy sharing models that are capable of providing electricity back to the grid during periods of high demand or outages.

Texas, with its vast and growing population, has faced significant energy challenges in recent years. The state’s power grid, managed by the Electric Reliability Council of Texas (ERCOT), has experienced strain during extreme weather events and high demand periods, and instances of Texas wind curtailment during grid stress, leading to concerns about reliability and stability. The partnership between Sunrun and Tesla seeks to address these concerns by introducing a more flexible and resilient energy solution.

The distributed power plant will consist of thousands of residential solar installations, each equipped with Tesla Powerwall batteries, reflecting the broader trend of pairing storage with solar across the U.S. as it scales. These batteries store excess solar energy generated during the day and release it when needed, such as during peak demand times or power outages. By connecting these systems through advanced software, the project will create a coordinated network of distributed energy resources that can respond dynamically to fluctuations in energy supply and demand.

One of the key benefits of this distributed approach is its ability to enhance grid reliability. Traditional power plants are centralized and can be vulnerable to disruptions, whether from extreme weather, technical failures, or other issues. In contrast, a distributed power plant spreads the generation and storage capacity across numerous locations, a principle echoed by renewable power developers pursuing multi-resource projects today, reducing the risk of widespread outages and increasing the overall resilience of the power grid.

Additionally, the project will contribute to the reduction of greenhouse gas emissions. By increasing the use of solar energy and reducing reliance on fossil fuels, and amid ongoing work to improve solar and wind technologies, the distributed power plant supports Texas’s climate goals and contributes to broader efforts to combat climate change. The integration of renewable energy sources into the grid helps to decrease carbon emissions and promote a cleaner, more sustainable energy system.

The partnership between Sunrun and Tesla also underscores the growing role of technology in transforming the energy landscape. Tesla's Powerwall battery systems represent some of the most advanced energy storage technology available, and amid record solar and storage growth nationwide this decade they showcase the capability to store and manage energy efficiently. Sunrun’s expertise in residential solar installations complements this technology, creating a powerful combination that leverages the latest advancements in clean energy.

The project is expected to deliver several benefits to both individual homeowners and the broader community. Homeowners who participate in the program will have access to solar energy and battery storage at reduced costs, thanks to the economies of scale and innovative financing options provided by Sunrun and Tesla. Additionally, they will have the added security of backup power during outages, contributing to greater energy independence and resilience.

For the broader community, the distributed power plant offers a more reliable and sustainable energy system. The ability to generate and store energy at the residential level reduces the strain on traditional power plants and enhances the overall stability of the grid. Furthermore, the project will contribute to local job creation, as the installation and maintenance of solar panels and battery systems require skilled workers.

As the project moves forward, Sunrun and Tesla will work closely with local stakeholders, regulators, and utility providers to ensure the successful implementation and integration of the distributed power plant. Collaboration with these parties will be essential to addressing any regulatory, technical, or logistical challenges and ensuring that the project delivers its intended benefits.

In conclusion, the partnership between Sunrun and Tesla to create a distributed power plant in Texas represents a significant advancement in clean energy technology and grid resilience. By combining solar power with advanced battery storage, the project aims to enhance grid stability, reduce emissions, and provide reliable energy solutions for homeowners. As Texas continues to face energy challenges, this innovative initiative offers a promising model for the future of distributed energy and highlights the potential for technology-driven solutions to address pressing environmental and infrastructure issues.

MeyGen Tidal Stream Project delivers record 13.8 GWh to Scotland's grid, showcasing renewable ocean energy. Simec Atlantis Energy's 6 MW array of tidal turbines advances EU power goals and plans an ocean-powered data center.

Key Points

A Scottish tidal energy array exporting record power, using four 1.5 MW turbines and driving renewable innovation.

✅ Delivered 13.8 GWh to the grid in 2019, a project record.

✅ Four 1.5 MW turbines in Phase 1A, 6 MW installed.

✅ Plans include an ocean-powered data center near site.

A tidal power project in waters off the north coast of Scotland, where Scotland’s wind farms also deliver significant output, sent more than 13.8 gigawatt hours (GWh) of electricity to the grid last year, according to an operational update issued Monday. This figure – a record – almost doubled the previous high of 7.4 GWh in 2018.

In total, the MeyGen tidal stream array has now exported more than 25.5 GWh of electricity to the grid since the start of 2017, according to owners Simec Atlantis Energy. Phase 1A of the project is made up of four 1.5 megawatt (MW) turbines.

The 13.8 GWh of electricity exported in 2019 equates to the average yearly electricity consumption of roughly 3,800 “typical” homes in the U.K., where wind power records have been set recently, according to the company, with revenue generation amounting to £3.9 million ($5.09 million).

Onshore maintenance is now set to be carried out on the AR1500 turbine used by the scheme, with Atlantis aiming to redeploy the technology in spring.

In addition to the production of electricity, Atlantis is also planning to develop an “ocean-powered data centre” near the MeyGen project.

The European Commission has described “ocean energy” as being both abundant and renewable, and milestones like the biggest offshore windfarm starting U.K. supply underscore wider momentum, too. It’s estimated that ocean energy could potentially contribute roughly 10% of the European Union’s power demand by the year 2050, according to the Commission.

While tidal power has been around for decades — EDF’s 240 MW La Rance Tidal Power Plant in France was built as far back as 1966, and the country’s first offshore wind turbine has begun producing electricity — recent years have seen a number of new projects take shape.

In December last year, Scottish tidal energy business Nova Innovation was issued with a permit to develop a project in Nova Scotia, Canada, aiming to harness the Bay of Fundy tides in the region further.

In an announcement at the time, the firm said a total of 15 tidal stream turbines would be installed by the year 2023. The project, according to the firm, will produce enough electricity to power 600 homes, as companies like Sustainable Marine begin delivering tidal energy to the Nova Scotia grid.

Elsewhere, a business called Orbital Marine Power is developing what it describes as the world’s most powerful tidal turbine, with grid-supplied output already demonstrated.

The company says the turbine will have a swept area of more than 600 square meters and be able to generate “over 2 MW from tidal stream resources.” It will use a 72-meter-long “floating superstructure” to support two 1 MW turbines.

Wildfire Resilient Power Grid Act proposes DOE grants for utility companies to fund wildfire mitigation, grid resilience upgrades, undergrounding power lines, fast-tripping protection, weather monitoring, and vegetation management, prioritizing rural electric cooperatives.

Key Points

A federal bill funding utility wildfire mitigation and grid hardening via DOE grants, prioritizing rural utilities.

✅ $1B DOE matching grants for grid upgrades and wildfire mitigation.

✅ Prioritizes rural utilities; supports undergrounding and hardening.

✅ Funds fast-tripping protection, weather stations, vegetation management.

U.S. Sens. Ron Wyden and Jeff Merkley today introduced new legislation, amid transmission barriers that persist, to incentivize utility companies to do more to reduce wildfire risks as aging power infrastructure ignite wildfires in Oregon and across the West.

Wyden and Merkley's Wildfire Resilient Power Grid Act of 2020 would ensure power companies do their part to reduce the risk of wildfires through power system upgrades, even as California utility spending crackdown seeks accountability, such as the undergrounding of power lines, fire safety equipment installation and proper vegetation management.

"First and foremost, this is a public safety issue. Fire after fire ignited this summer because the aging power grid could not withstand a major windstorm during the season's hottest and driest days," Wyden said. "Many utility companies are already working to improve the resiliency of their power grid, but the sheer costs of these investments must not come at the expense of equitable regulation for rural utility customers. Congress must do all that it can to stop the catastrophic wildfires decimating the West, and that means improving rural infrastructure. By partnering with utilities around the country, we can increase wildfire mitigation efforts at a modest cost -- a fire prevention investment that will pay dividends by saving lives, homes and businesses."

"When this year's unprecedented wildfire event hit, I drove hundreds of miles across our state to see the damage firsthand and to hear directly from impacted communities, so that I could go back to D.C. and work for the solutions they need," said Merkley. "What I saw was apocalyptic--and we have to do everything we can to reduce the risk of this happening again. That means we have to work with our power companies to get critical upgrades and safety investments into place as quickly as possible."

The Wildfire Resilient Power Grid Act of 2020:

* Establishes a $1 billion-per-year matching grant program for power companies through the Department of Energy, even as ACORE opposed DOE subsidy proposals, to reduce the risk of power lines and grid infrastructure causing wildfires.

* Gives special priority to smaller, rural electric companies to ensure mitigation efforts are targeted to forested rural areas.

* Promotes proven methods for reducing wildfire risks, including undergrounding of lines, installing fast-tripping protection systems, and constructing weather monitoring stations to respond to electrical system fire risks.

* Provides for hardening of overhead power lines and installation of fault location equipment where undergrounding of power lines is not a favorable option.

* Ensures fuels management activities of power companies are carried out in accordance with Federal, State, and local laws and regulations.

* Requires power companies to have "skin in the game" by making the program a 1-to-1 matching grant, with an exception for smaller utilities where the matching requirement is one third of the grant.

* Delivers accountability on the part of utilities and the Department of Energy by generating a report every two years on efforts conducted under the grant program.

Portland General Electric President and CEO Maria Pope: "We appreciate Senator Wyden's and Senator Merkley's leadership in proposing legislation to provide federal funding that will help protect Oregon from devastating wildfires. When passed, this will help make Oregon's electric system safer, faster, without increasing customer prices. That is especially important given the economy and hotter, drier summers and longer wildfire seasons that Oregon will continue to face."

Lane County Commission Chair Heather Butch: " In a matter of hours, the entire Lane County community of Blue River was reduced to ashes by the Holiday Farm Fire. Since the moment I first toured that devastation I've been committed to building it back better. I applaud Senators Wyden and Merkley for drafting the Wildfire Resilient Power Grid Act, as it could well provide the path towards meeting this important goal. Moreover, the resultant programs will better protect rural communities from the increasing dangers of wildfires through a number of preventative measures that would otherwise be difficult to implement."

Linn County Commissioner Roger Nyquist: "This legislation is a smart strategic investment for the future safety of our residents as well as the economic vitality of our community."

Marion County Commissioner Kevin Cameron: "After experiencing a traumatic evacuation during the Beachie Creek and Lion's Head wild fires, I understand the need to strengthen the utility Infrastructure. The improvements resulting from Senator Wyden and Merkley's bill will reduce disasters in the future, but improve everyday reliability for our citizens who live, work and protect the environment in potential wildfire areas."

Edison Electric Institute President Tom Kuhn: "EEI thanks Senator Wyden and Senator Merkley for their leadership in introducing the Wildfire Resilient Power Grid Act. This bill will help support and accelerate projects already planned and underway to enhance energy grid resiliency and mitigate the risk of wildfire damage to power lines. Electric companies across the country are committed to working with our government partners and other stakeholders on preparation and mitigation efforts that combat the wildfire threat and on the rapid deployment of technology solutions, including aggregated DERs at FERC, that address wildfire risks, while still maintaining the safe, reliable, and affordable energy we all need."

Oregon Rural Electric Cooperative Association Executive Director Ted Case: "Oregon's electric cooperatives support the Wildfire Resilient Power Grid Act and appreciate Senator Wyden's and Senator Merkley's leadership and innovative approach to wildfire mitigation, particularly for small, rural utilities. This legislation includes targeted assistance that will help us to continue to provide affordable, reliable and safe electricity to over 500,000 Oregonians."

Sustainable Northwest Director of Government Affairs & Program Strategy Dylan Kruse: "In recent years, the West has seen too many wildfires originate due to poorly maintained or damaged electric utility transmission and distribution infrastructure. This legislation plays an important role to ensure that power lines do not contribute to wildfire starts, while providing safe and reliable power to communities during wildfire events. Utilities must, even as Wyoming clean energy bill proposals emerge, live up to their legal requirements to maintain their infrastructure, but this bill provides welcome resources to expedite and prioritize risk reduction, while preventing cost increases for ratepayers."

Oregon Wild Wilderness Program Manager Erik Fernandez: "2020 taught Oregon the lesson that California learned in the Paradise Fire, and SCE wildfire lawsuits that followed underscore the stakes. Addressing the risk of unnaturally caused powerline fires is an increasingly important critical task. I appreciate Senator Ron Wyden's efforts to protect our homes and communities from powerline fires."

Site C Dam Controversy highlights Peace River risks, BC Hydro claims, Indigenous rights under Treaty 8, environmental assessment findings, and potential impacts to agriculture and the Peace-Athabasca Delta across Alberta and the Northwest Territories.

Key Points

Debate over BC Hydro's Site C dam: clean energy vs Indigenous rights, Peace-Athabasca Delta impacts, and agriculture.

✅ Potential drying of Peace-Athabasca Delta and wildlife habitat

✅ Treaty 8 rights and First Nations legal challenges

✅ Loss of prime Peace Valley farmland; alternatives in renewables

One of the leading opponents of the Site C dam in northeastern B.C. is sharing her concerns with northerners this week.

Proponents of the Site C dam say it will be a cost-effective source of clean electricity, even as a major Alberta wind farm was scrapped elsewhere in Canada, and that it will be able to produce enough energy to power the equivalent of 450,000 homes per year in B.C. But a number of Indigenous groups and environmentalists are against the project.

Wendy Holm is an economist and agronomist who did an environmental assessment of the dam focusing on its potential impacts on agriculture.

On Tuesday she spoke at a town hall presentation in Fort Smith, N.W.T., organized by the Slave River Coalition. She is also speaking at an event in Yellowknife on Friday, as small modular reactors in Yukon receive study as a potential long-term option.

Worried about downstream impacts, Northern leaders urge action on Site C dam

"I learned that people outside of British Columbia are as concerned with this dam as we are," Holm said.

"There's just a lot of concern with what's happening on the Peace River and this dam and the implications for Alberta, where hydro's share has diminished in recent decades, and the Northwest Territories."

If completed, BC Hydro's Site C energy project will be the third dam on the Peace River in northeast B.C. and the largest public works project in B.C. history. The $10.7-billion project was approved by both the provincial and federal governments as B.C. moves to streamline clean energy permitting for future projects.

Amy Lusk, co-ordinator of the Slave River Coalition, said many issues were discussed at the town hall, but she also left with a sense of hope.

"I think sometimes in our little corner of the world, we are up against so much when it comes to industrial development and threats to our water," she said.

"To kind of take away that message of, this is not a done deal, and that we do have a few options in place to try and stop this and not to lose hope, I think was a very important message for the community."

Drying of the Peace-Athabasca Delta

Holm said her main concern for the Northwest Territories is how it could affect the Peace-Athabasca Delta. She said the two dams already on the river are responsible for two-thirds of the drying that's happening in the delta.

"These are very real issues and very present in the minds of northerners who want to stay connected to a traditional lifestyle, want to have access to those wild foods," she said.

Lusk said northerners are fed up with defending waters "time after time after time."

BC Hydro, however, said studies commissioned during the environmental assessment of Site C show the project will have no measurable effect on the delta, which is located 1,100 kilometres away.

Holm said the fight against the Site C dam is also important when it comes to First Nations treaty rights.

The West Moberly and Prophet River First Nations applied for an injunction to halt construction on Site C, as well as a treaty infringement lawsuit against the B.C. government. They argue the dam would cause irreparable harm to their territories and way of life, which are rights protected under Treaty 8.

Agricultural land

While the project is located in B.C., Holm said its impacts on prime horticulture land would also affect northerners, something that's important given issues of food security and nutrition.

"This is some of the best agriculture land in all of Canada," she said of the Peace Valley.

According to BC Hydro, around 2.6 million hectares of land in the Peace agricultural region would remain available for agricultural production while 3,800 hectares would be unavailable. It has also proposed a number of mitigation efforts, including a $20-million agricultural compensation fund.

Holm said renewable energy, including tidal energy for remote communities, will be cheaper and less destructive than the dam, and there's a connection between the dams on the Peace River and water sharing with the U.S.

"When you run out of water there's nothing else you can use. You can't use orange juice to irrigate your fields or to run your industries or to power your homes," she said.

Duke Energy zero-coal 2050 plan outlines a decarbonized energy mix, aligning with Paris goals, cutting greenhouse gas emissions, driven by investor pressure, shifting to natural gas, extending nuclear power, and phasing out coal.

Key Points

An investor-driven scenario to end coal by 2050, shift to natural gas, extend nuclear plants, and manage climate risk.

✅ Eliminates coal from the generation mix by 2050

✅ Prioritizes natural gas transitions without CCS breakthroughs

✅ Extends nuclear plant licenses to limit carbon emissions

One of America’s largest utility companies, Duke Energy, is set to release a report later this month that sketches a drastically changed electricity mix in a carbon-constrained future.

The big picture: Duke is the latest energy company to commit to releasing a report about climate change in response to investor pressure, echoing shifts such as Europe's oil majors going electric across the sector, conveyed by non-binding but symbolically important shareholder resolutions. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: The report is expected to find that coal, currently 33% of Duke’s mix, gone entirely from its portfolio by 2050 in a future scenario where the world has taken steps to cut greenhouse gas emissions, and where global coal-fired electricity use is falling markedly, to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

What they're saying: “What’s difficult about this is we are trying to overlay what we understand currently about technology,” Lynn Good, Duke CEO, told Axios in an interview on the sidelines of a major energy conference here.

She went on to say that this scenario of zero coal by 2050 doesn’t assume any breakthroughs in technology that captures carbon emissions from coal-fired power plants. “We don’t see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas.”

Good also stressed the benefits of its several nuclear power plants, highlighting the role of sustaining U.S. nuclear power in decarbonization, which emit no carbon emissions. She said Duke isn’t considering investing in new nuclear plants, but plans to seek federal relicensing of current plants.

“If I turn them off, the resource that would replace them today is natural gas, so carbon will go up,” Good said. “Our objective is to continue to keep those plants as long as possible.”

What’s next: A spokesman said the other details of their 2050 scenario estimates will be available when the report is officially released by month’s end.

Axios reports that Duke Energy will release a report later this month that detail the utility's efforts to mitigate climate change risks and plan carbon-free electricity investments across its operations. The report includes a scenario that eliminates coal entirely from the company's power mix by 2050. Coal currently makes up about a third of Duke's generation.

Duke CEO Lynn Good told the news outlet the scenario ending coal-fired generation assumes no technological advances in emissions capture, seemingly leaving open the possibility.

Last year, a report by the Union of Concerned Scientists concluded one in four of the remaining operating coal-fired plants in the U.S. are slated for closure or conversion to natural gas, amid falling power-sector carbon emissions across the country. Duke's report is expected to be released by the end of the month.

Duke's report on its carbon plans comes at the behest of shareholders, a trend utility companies have seen growing among investors who are increasingly concerned about companies' sustainability and their financial exposure to climate policy.

Last year, a majority of shareholders of Pennsylvania utility PPL Corp. called on company management to publish a report on how climate change policies and technological innovations will affect the company's bottom line. Almost 60% of shareholders voted in favor of the non-binding proposal.

The vote, reportedly a first for the power sector, followed a similar decision by shareholders of Occidental Petroleum, which was supported by about 66% of shareholders.

Duke's Good told Axios that right now the utility does not see the coal technology on the horizon that would keep it operating plants. “We don't see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas," Good said. However, it does not mean the utility is making near-term efforts to erase coal from its power mix. However, some utilities are taking those steps as they prepare for en energy landscape with more carbon regulations.

In addition to the 25% of coal plants heading for closure or conversion, the UCS report also said that another 17% of the nation’s operating coal plants are uneconomic compared with natural gas-fired generation, and could face retirement soon. But there is plenty of ongoing research into "clean coal" possibilities, and the federal government has expressed an interest in smaller, modular coal units.
