Renewable electricity powered California just shy of 100% for the first time in history

FERC Transmission Rule accelerates grid modernization and interregional high-voltage lines, enabling renewable energy integration, load balancing, and reliability to advance net-zero goals while strengthening resilience, capacity expansion, and decarbonization across U.S. regional transmission organizations.

Key Points

A federal policy mandating interregional grid planning and cost sharing to expand high-voltage lines for renewables.

✅ Expands interregional high-voltage transmission capacity

✅ Improves reliability, resilience, and load balancing

✅ Aligns cost allocation and long-term planning for renewables

On May 13th, 2024, the US took a monumental step towards its clean energy goals. The Federal Energy Regulatory Commission (FERC) approved a long-awaited rule designed to significantly expand the transmission of renewable energy across the nation's power grid, a US grid overhaul that many advocates say was overdue. This decision aligns with President Biden's ambitious plan to achieve net-zero carbon emissions by 2050, with renewable energy playing a central role.

The new rule tackles a critical bottleneck hindering the widespread adoption of renewables – transmission infrastructure. Unlike traditional power plants like coal or natural gas that run constantly, solar and wind power generation fluctuates with weather conditions. This variability poses a challenge for the existing grid, which is not designed to efficiently handle large-scale integration of these intermittent sources, helping explain why the grid isn't 100% renewable today.

The FERC rule aims to address this by promoting the construction of new, high-voltage transmission lines, particularly those connecting different regions, where grid limitations in the Pacific Northwest have highlighted the need for better interregional transfers. This improved connectivity would allow for a more strategic distribution of renewable energy. Imagine solar energy harnessed in the sun-drenched Southwest being transmitted eastward to meet peak demand during hot summer days on the Atlantic Coast.

The benefits of this expanded transmission network are multifaceted. First, it unlocks the full potential of renewable resources by allowing for their efficient utilization across the country, a trend consistent with wind and solar surpassing coal in U.S. generation. Abundant wind power in the Midwest could be utilized on the West Coast, while surplus solar energy from the South could supplement demand in the Northeast.

Second, a more robust grid with a higher capacity for renewables reduces reliance on fossil fuel-based power plants and complements other ways to meet decarbonization goals across sectors. This translates to cleaner air and a significant reduction in greenhouse gas emissions, contributing to the fight against climate change.

Third, a modernized grid with improved long-distance transmission bolsters the nation's energy security. Extreme weather events, a growing concern due to climate change, can disrupt energy production in specific regions. This interconnected grid would provide a buffer, ensuring a more reliable and resilient power supply and helping put regions on the road to 100% renewables even during adverse weather conditions.

The FERC's decision is a win for environmental groups and the renewable energy industry. They see it as a critical step towards a cleaner energy future and a significant driver of job creation in the construction and maintenance of new transmission lines. However, concerns have been raised by some stakeholders, particularly investor-owned utilities. They worry about the potential cost burden associated with building these expansive new lines, and recent reports of stalled grid spending underscore those concerns and the need for efficient cost allocation mechanisms. Striking a balance between efficiency, affordability, and environmental responsibility will be crucial for the successful implementation of this policy.

California Grid Transition drives decarbonization with renewable energy, EV charging, microgrids, and energy storage, while tackling wildfire risk, aging infrastructure, and cybersecurity threats to build grid resilience and reliability across a rapidly electrifying economy.

Key Points

California Grid Transition is the statewide shift to renewables, storage, EVs, and resilient, secure infrastructure.

✅ Integrates solar, wind, storage, and demand response at scale

✅ Expands microgrids and DERs to enhance reliability and resilience

✅ Addresses wildfire, aging assets, and cybersecurity risks

Gretchen Bakke thinks a lot about power—the kind that sizzles through a complex grid of electrical stations, poles, lines and transformers, keeping the lights on for tens of millions of Californians who mostly take it for granted.

They shouldn’t, says Bakke, who grew up in a rural California town regularly darkened by outages. A cultural anthropologist who studies the consequences of institutional failures, she says it’s unclear whether the state’s aging electricity network and its managers can handle what’s about to hit it, as U.S. blackout risks continue to mount.

California is casting off fossil fuels to become something that doesn’t yet exist: a fully electrified state of 40 million people. Policies are in place requiring a rush of energy from renewable sources such as the sun and wind and calling for millions of electric cars that will need charging—changes that will tax a system already fragile, unstable and increasingly vulnerable to outside forces.

“There is so much happening, so fast—the grid and nearly everything about energy is in real transition, and there’s so much at stake,” said Bakke, who explores these issues in a book titled simply, “The Grid.”

The state’s task grew more complicated with this week’s announcement that Pacific Gas and Electric, which provides electricity for more than 5 million customer accounts, intends to file for bankruptcy in the face of potentially crippling liabilities from wildfires. But the reshaping of California’s energy future goes far beyond the woes of a single company.

The 19th-century model of one-way power delivery from utility companies to customers is being reimagined. Major utilities—and the grid itself—are being disrupted by rooftops paved with solar panels and the rise of self-sufficient neighborhood mini-grids. Whole cities and counties are abandoning big utilities and buying power from wholesalers and others of their choosing.

With California at the forefront of a new energy landscape, officials are racing to design a future that will not just reshape power production and delivery but also dictate how we get around and how our goods are made. They’re debating how to manage grid defectors, weighing the feasibility of an energy network that would expand to connect and serve much of the West and pondering how to appropriately regulate small power producers.

“We are in the depths of the conversation,” said Michael Picker, president of the state Public Utilities Commission, who cautions that even as the system is being rebooted, like repairing a car while driving in practice, there’s no real plan for making it all work.

Such transformation is exceedingly risky and potentially costly. California still bears the scars of having dropped its regulatory reins some 20 years ago, leaving power companies to bilk the state of billions of dollars it has yet to completely recover. And utility companies will undoubtedly pass on to their customers the costs of grid upgrades to defend against natural and man-made threats.

Some weaknesses are well known—rodents and tree limbs, for example, are common culprits in power outages, even as longer, more frequent outages afflict other parts of the U.S. A gnawing squirrel squeezed into a transformer on Thanksgiving Day three years ago, shutting off power to parts of Los Angeles International Airport. The airport plans to spend $120 million to upgrade its power plant.

But the harsh effects of climate change expose new vulnerabilities. Rising seas imperil coastal power plants. Electricity infrastructure is both threatened by and implicated in wildfires. Picker estimates that utility operations are related to one in 10 wildland fires in California, which can be sparked by aging equipment and winds that send tree branches crashing into power lines, showering flammable landscapes with sparks.

California utilities have been ordered to make their lines and equipment more fire-resistant as they’re increasingly held accountable for blazes they cause. Pacific Gas and Electric reported problems with some of its equipment at a starting point of California’s deadliest wildfire, which killed at least 86 people in November in the town of Paradise. The cause of the fire is under investigation.

New and complex cyber threats are more difficult to anticipate and even more dangerous. Computer hackers, operating a world away, can—and have—shut down electricity systems, toggling power on and off at will, and even hijacked the computers of special teams dispatched to restore control.

Thomas Fanning, CEO of Southern Co., one of the country’s largest utilities, recently disclosed that his teams have fended off multiple attempts to hack a nuclear power plant the firm operates. He called grid hacking “the most important under-reported war in American history.”

However, if you’ve got what seems like an insoluble problem requiring a to-the-studs teardown and innovative rebuild, California is a good place to start. After all, the first electricity grid was built in San Francisco in 1879, three years before Thomas Edison’s power station in New York City. (Edison’s plant burned to the ground a decade later.)

California’s energy-efficiency regulations have helped reduce statewide energy use, which peaked a decade ago and is on the decline, somewhat easing pressure on the grid. The major utilities are ahead of schedule in meeting their obligation to obtain power from renewable sources.

California’s universities are teaming with national research labs to develop cutting-edge solutions for storing energy produced by clean sources. California is fortunate in the diversity of its energy choices: hydroelectric dams in the north, large-scale solar operations in the Mojave Desert to the east, sprawling windmill farms in mountain passes and heat bubbling in the Geysers, the world’s largest geothermal field north of San Francisco. A single nuclear-power plant clings to the coast near San Luis Obispo, but it will be shuttered in 2025.

But more renewable energy, accessible at the whims of weather, can throw the grid off balance. Renewables lack the characteristic that power planners most prize: dispatchability, ready when called on and turned off when not immediately needed. Wind and sun don’t behave that way; their power is often available in great hunks—or not at all, as when clouds cover solar panels or winds drop.

In the case of solar power, it is plentiful in the middle of the day, at a time of low demand. There’s so much in California that most days the state pays its neighbors to siphon some off,  lest the excess impede the grid’s constant need for balance—for a supply that consistently equals demand.

So getting to California’s new goals of operating on 100 percent clean energy by 2045 and having 5 million electric vehicles within 12 years will require a shift in how power is acquired and managed. Consumers will rely more heavily on battery storage, whose efficiency must improve to meet that demand.

UK Wind Power Surpasses Gas as offshore wind and solar drive record electricity generation, National Grid milestones, and net zero progress, despite grid capacity bottlenecks, onshore planning reforms, demand from heat pumps and transport electrification.

Key Points

A milestone where wind turbines generated more UK electricity than gas, advancing progress toward a net zero grid.

✅ Offshore wind delivered the majority of UK wind generation

✅ Grid connection delays stall billions in green projects

✅ Planning reforms may restart onshore wind development

Wind turbines have generated more electricity than gas, as wind becomes the main source for the first time in the UK.

In the first three months of this year a third of the country's electricity came from wind farms, as the UK set a wind generation record that underscored the trend, research from Imperial College London has shown.

National Grid has also confirmed that April saw a record period of solar energy generation, and wind and solar outproduced nuclear in earlier milestones.

By 2035 the UK aims for all of its electricity to have net zero emissions, after a 2019 stall in low-carbon generation highlighted the challenge.

"There are still many hurdles to reaching a completely fossil fuel-free grid, but wind out-supplying gas for the first time is a genuine milestone event," said Iain Staffell, energy researcher at Imperial College and lead author of the report.

The research was commissioned by Drax Electrical Insights, which is funded by Drax energy company.

The majority of the UK's wind power has come from offshore wind farms, and the country leads the G20 for wind's electricity share according to recent analyses. Installing new onshore wind turbines has effectively been banned since 2015 in England.

Under current planning rules, companies can only apply to build onshore wind turbines on land specifically identified for development in the land-use plans drawn up by local councils. Prime Minister Rishi Sunak agreed in December to relax these planning restrictions to speed up development.

Scientists say switching to renewable power is crucial to curb the impacts of climate change, which are already being felt, including in the UK, which last year recorded its hottest year since records began.

Solar and wind have seen significant growth in the UK, with wind surpassing coal in 2016 as a milestone. In the first quarter of 2023, 42% of the UK's electricity came from renewable energy, with 33% coming from fossil fuels like gas and coal.

But BBC research revealed on Thursday that billions of pounds' worth of green energy projects are stuck on hold due to delays with getting connections to the grid, as peak power prices also climbed amid system pressures.

Some new solar and wind sites are waiting up to 10 to 15 years to be connected because of a lack of capacity in the electricity system.

And electricity only accounts for 18% of the UK's total power needs. There are many demands for energy which electricity is not meeting, such as heating our homes, manufacturing and transport.

Currently the majority of UK homes use gas for their heating - the government is seeking to move households away from gas boilers and on to heat pumps which use electricity.

New York Utility Disconnection Ban protects residents during state emergencies, covering electric, gas, water, telecommunications, cable, and internet services, with penalties for noncompliance and options like deferred payment agreements and consumer protections.

Key Points

A proposed law barring shutoffs in state emergencies across electric, gas, water, telecom, cable, and internet.

✅ Applies during declared state and local emergencies statewide.

✅ Covers electric, gas, water, telecom, cable, and internet services.

✅ Noncompliance triggers penalties; payment plans required for arrears.

Governor Andrew M. Cuomo has announced a proposal to prohibit utility disconnections in regions that are under a state of emergency, addressing the energy insecurity many households face, as part of the 2021 State of the State. The Governor will propose legislation that will apply to electric, gas, water, telecommunications, cable and internet services. Utilities that fail to comply will be subject to penalties.

“In a year in which we dealt with an unprecedented pandemic, ferocious storms added insult to injury by knocking out power for hundreds of thousands of New Yorkers,” Governor Cuomo said. “Utility companies provide essential services, and we need to make sure they continue to provide them, rain or shine. That’s why we’re proposing legislation to make sure that New Yorkers, especially those living in regions under states of emergency, have access to these critical services to provide for themselves and their families.”

Governor Cuomo has taken a series of actions to protect New Yorkers’ access to utilities during the COVID-19 pandemic, including a suspension of shut-offs in New York and New Jersey, among other measures. Last year, the Governor signed legislation extending a moratorium that prevents utility companies from disconnecting utilities to residential households that are struggling with their bills due to the COVID-19 pandemic, a move mirrored by reconnection efforts in Ontario by Hydro One. Utility companies must instead offer these individuals a deferred payment agreement on any past-due balance. 

On November 19, Governor Cuomo announced that Con Edison now faces $25 million in penalties and possible license revocation from the New York State Public Service Commission, amid a broader review of retail energy markets by state regulators, following an investigation into the utility’s failed response during large-scale power outages in Manhattan and Brooklyn in July 2019. On November 2, Governor Cuomo announced that more than $328 million in home heating aid is now available, similar to Ontario bill support during the pandemic, for low- and middle-income New Yorkers who need assistance keeping their homes warm during the coming winter season.

The Governor has previously enacted some of the strongest and most progressive consumer protection and assistance programs in the country, including smart streetlights in Syracuse that reduce energy costs, and other initiatives. Governor Cuomo established New York’s energy affordability policy in 2016, as states pursue renewable energy ambitions that can affect rates, underscoring the need for affordability. The policy extended energy bill support to more than 152,000 additional New York families, ensuring that more than 920,000 New York families spend no more than 6 percent of their income on energy bills. Through this program, New York commits more than $238 million annually helping to keep the lights and heat on for our most vulnerable New Yorkers, while actively striving to expand coverage to additional families.

Fort Frances Microgrid aims to boost reliability in Ontario with grid-connected and island modes, Siemens feasibility study, renewable energy integration, EV charging expansion, and resilience modeled after First Nations projects and regional biomass initiatives.

Key Points

A community microgrid in Fort Frances enabling grid and island modes to improve reliability and integrate renewables.

✅ Siemens-led feasibility via FedNor funding

✅ Grid-connected or islanded for outage resilience

✅ Integrates renewables, EV charging, and industry growth

When the power goes out in Fort Frances, Ont., the community may be left in the dark for hours.

The hydro system's unreliability — caused by its location on the provincial power grid — has prompted the town to seek a creative solution: its own self-contained electricity grid with its own source of power, known as a microgrid. 

Located more than 340 kilometres west of Thunder Bay, Ont., on the border of Minnesota, near the Great Northern Transmission Line corridor, Fort Frances gets its power from a single supply point on Ontario's grid. 

"Sometimes, it's inevitable that we have to have like a six- to eight-hour power outage while equipment is being worked on, and that is no longer acceptable to many of our customers," said Joerg Ruppenstein, president and chief executive officer of Fort Frances Power Corporation.

While Ontario's electrical grid serves the entire province, and national efforts explore macrogrids, a microgrid is contained within a community. Fort Frances hopes to develop an integrated, community-based electric microgrid system that can operate in two modes:

• Grid-connected mode, which means it's connected to the provincial grid and informed by western grid planning approaches
• Island mode, which means it's disconnected from the provincial grid and operates independently

The ability to switch between modes allows flexibility. If a storm knocks down a line, the community will still have power.

The town has been given grant funding from the Federal Economic Development Agency for Northern Ontario (FedNor), echoing smart grid funding in Sault Ste. Marie initiatives, for the project. On Monday night, council voted to grant a request for proposal to Siemens Canada Limited to conduct a feasibility study into a microgrid system.

The study, anticipated to be completed by the end of 2023 or early 2024, will assess what an integrated community-based microgrid system could look like in the town of just over 7,000 people, said Faisal Anwar, chief administrative officer of Fort Frances. A timeline for construction will be determined after that. 

The community is still reeling from the closure of the Resolute Forest Products pulp and paper mill in 2014 and faces a declining population, said Ruppenstein. It's hoped the microgrid system will help attract new industry to replace those lost workers and jobs, drawing on Manitoba's hydro experience as a model.

This gives the town a competitive advantage.

"If we were conceivably to attract a larger industrial player that would consume a considerable amount of energy, it would result in reduced rates for everyone…we're the only utility really in Ontario that can offer that model," Ruppenstein said.

The project can also incorporate renewable energy like solar or wind power, as seen in B.C.'s clean energy shift efforts, into the microgrid system, and support the growth of electric vehicles, he said. Many residents fill their gas tanks in Minnesota because it's cheaper, but Fort Frances has the potential to become a hub for electric vehicle charging.

A few remote First Nations have recently switched to microgrid systems fuelled by green energy, including Gull Bay First Nation and Fort Severn First Nation. These are communities that have historically relied on diesel fuel either flown in, which is incredibly expensive, or transported via ice roads, which are seeing shorter seasons each year.

Natural Resources Minister Jonathan Wilkinson was in Thunder Bay, Ont., to announce $35 million for a biomass generation facility in Whitesand First Nation, complementing federal funding for the Manitoba-Saskatchewan transmission line elsewhere in the region.

Ontario Electricity Grid Decarbonization outlines the IESO's net-zero pathway: $400B investment, nuclear expansion, renewables, hydrogen, storage, and demand management to double capacity by 2050 while initiating a 2027 natural gas moratorium.

Key Points

A 2050 plan to double capacity, retire gas, and invest $400B in nuclear, renewables, and storage for a net-zero grid.

✅ $400B over 25 years to meet net-zero electricity by 2050

✅ Capacity doubles to 88,000 MW; demand grows ~2% annually

✅ 2027 gas moratorium; build nuclear, renewables, storage

Ontario will need to spend $400 billion over the next 25 years in order to decarbonize the electricity grid and embrace clean power according to a new report by the province’s electricity system manager that’s now being considered by the Ford government.

The Independent System Electricity Operator (IESO) was tasked with laying out a path to reducing Ontario’s reliance on natural gas for electricity generation and what it would take to decarbonize the entire electricity grid by 2050.

Meeting the goal, the IESO concluded, will require an “aggressive” approach of doubling the electricity capacity in Ontario over the next two-and-a-half decades — from 42,000 MW to 88,000 MW — by investing in nuclear, hydrogen and wind and solar power while implementing conservation policies and managing demand.

“The process of fully eliminating emissions from the grid itself will be a significant and complex undertaking,” IESO president Lesley Gallinger said in a news release.

The road to decarbonization, the IESO said, begins with a moratorium on natural gas power generation starting in 2027 as long as the province has “sufficient, non-emitting supply” to meet the growing demands on the grid.

The approach, however, comes with significant risks.

The IESO said hydroelectric and nuclear facilities can take 10 to 15 years to build and if costs aren’t controlled the plan could drive up the price of clean electricity, turning homeowners and businesses away from electrification.

“Rapidly rising electricity costs could discourage electrification, stifle economic growth or hurt consumers with low incomes,” the report states.

The IESO said the province will need to take several “no regret” actions, including selecting sites and planning to construct new large-scale nuclear plants as well as hydroelectric and energy storage projects and expanding energy-efficiency programs beyond 2024.

Ontario’s minister of energy didn’t immediately commit to implementing the recommendations, citing the need to consult with stakeholders first.

“I look forward to launching a consultation in the new year on next steps from today’s report, including the potential development of major nuclear, hydroelectric and transmissions projects,” Todd Smith said in a statement.

Currently, electricity demand is increasing by roughly two per cent per year, raising concerns Ontario could be short of electricity in the coming years as the manufacturing and transportation sectors electrify and as more sectors consider decarbonization.

At the same time, the province’s energy supply is facing “downward pressure” with the Pickering nuclear power plant slated to wind down operations and the Darlington nuclear generating station under active refurbishment.

To meet the energy need, the Ford government said it intended to extend the life of the Pickering plant until 2026.

But to prepare for the increase, the Ontario government was told the province would also need to build new natural gas facilities to bridge Ontario’s electricity supply gap in the near term — a recommendation the Ford government agreed to.

The IESO said a request for proposals has been opened and the province is looking for host communities, with the expectation that existing facilities would be upgraded before projects on undeveloped land would be considered.

The IESO said the contract for any new facilities would expire in 2040, and all natural gas facilities would be retired in the 2040s.
