California Electricity Reserve Mandate requires 3.3 GW of new capacity to bolster grid reliability amid solar power volatility, peak demand, and wildfire-driven blackouts, as CPUC directs PG&E, Edison, and Sempra to procure resource adequacy.

Key Points

A CPUC order for utilities to add 3.3 GW of reserves, safeguarding grid reliability during variable renewables and peaks

✅ 3.3 GW procurement to meet resource adequacy targets

✅ Focus on grid reliability during peak evening demand

✅ Prioritizes renewables, storage; limits new fossil builds

As if California doesn’t have enough problems with its electric service, now state regulators warn the state may be short on power supplies by 2021 if utilities don’t start lining up new resources now.

In the hopes of heading off a shortfall as America goes electric, the California Public Utilities Commission has ordered the state’s electricity providers to secure 3.3 additional gigawatts of reserve supplies. That’s enough to power roughly 2.5 million homes. Half of it must be in place by 2021 and the rest by August 2023.

The move comes as California is already struggling to accommodate increasingly large amounts of solar power that regularly send electricity prices plunging below zero and force other generators offline so the region’s grid doesn’t overload. The state is also still reeling from a series of deliberate mass blackouts that utilities imposed last month to keep their power lines from sparking wildfires amid strong winds. And its largest power company, PG&E Corp., went bankrupt in January.

Now as natural gas-fired power plants retire under the state’s climate policies, officials are warning the state could run short on electricity on hot evenings, when solar production fades and commuters get home and crank up their air conditioners. “We have fewer resources that can be quickly turned on that can meet those peaks,” utilities commission member Liane Randolph said Thursday before the panel approved the order to beef up reserves.

The 3.3 gigawatts that utilities must line up is in addition to a state rule requiring them to sign contracts for 15% more electricity than they expect to need. Some critics question the need for added supplies, particularly after the state went on a plant-building boom in the 2000s.

But California’s grid managers say the risk of a shortfall is real and could be as high as 4.7 gigawatts, especially during heat waves that test the grid again. Mark Rothleder, with the California Independent System Operator, said the 15% cushion is a holdover from the days before big solar and wind farms made the grid more volatile. Now it may need to be increased, he said.

“We’re not in that world anymore,” said Rothleder, the operator’s vice president of state regulatory affairs. “The complexity of the system and the resources we have now are much different.”

The state’s three major utilities, PG&E, Edison International and Sempra Energy, will be largely responsible for securing new supplies. The commission banned fossil fuels from being used at any new power generators built to meet the requirement — though it left the door open for expansions at existing ones.

Some analysts argue California is exporting its energy policies to Western states, making electricity more costly and less reliable.

PG&E said in an emailed statement that it was pleased the commission didn’t adopt an earlier proposal to require 4 gigawatts of additional resources. Edison similarly said it was “supportive.” Sempra didn’t immediately respond with comment.

Extending Deadlines

The pending plant closures are being hastened by a 2020 deadline requiring California’s coastal generators to stop using aging seawater-cooling systems. Some gas-fired power plants have said they’ll simply close instead of installing costly new cooling systems. So the commission on Thursday also asked California water regulators to extend the deadline for five plants.

The Sierra Club, meanwhile, called on regulators to turn away from fossil fuels altogether, saying their decision Thursday “sets California back on its progress toward a clean energy future.”

The move to push back the deadline also faces opposition from neighboring towns. Redondo Beach Mayor Bill Brand, whose city is home to one of the plants in line for an extension, told the commission it wasn’t necessary, since California utilities already have plenty of electricity reserves.

“It’s just piling on to that reserve margin,” Brand said.

West and Central Africa Electricity Access hinges on utility reform, renewable energy, off-grid solar, mini-grids, battery storage, and regional grid integration, lowering costs, curbing energy poverty, and advancing SDG7 with sustainable, reliable power solutions.

Key Points

Expanding reliable power via renewables, grid trade, and off-grid systems to cut energy poverty and unlock inclusive growth.

✅ Utility reform lowers costs and improves service reliability

✅ Regional grid integration enables clean, least-cost power trade

✅ Off-grid solar and mini-grids electrify remote communities

As commodity prices soar and leaders around the world worry about energy shortages and prices of gasoline at the pump, millions of people in Africa still lack access to electricity.  One-half of the people on the continent cannot turn on a fan when temperatures go up, can’t keep food cool, or simply turn the lights on. This energy access crisis must be addressed urgently.

In West and Central Africa, only three countries are on track to give every one of their people access to electricity by 2030. At this slow pace, 263 million people in the region will be left without electricity in ten years.  West Africa has one of the lowest rates of electricity access in the world; only about 42% of the total population, and 8% of rural residents, have access to electricity.

These numbers, some far too big, others far too small, have grave consequences. Electricity is an important step toward enhancing people’s opportunities and choices. Access is key to boosting economic activity and contributes to improving human capital, which, in turn, is an investment in a country’s potential.  

Without electricity, children can’t do their schoolwork at night. Businesspeople can’t get information on markets or trade with each other. Worse, as the COVID-19 pandemic has shown so starkly, limited access to energy constrains hospital and emergency services, further endangering patients and spoiling precious medicine.  

What will it take to power West and Central Africa?  
As the African continent recovers from COVID-19 impacts, now is the critical time to accelerate progress towards universal energy access to drive the region’s economic transformation, promote socio-economic inclusion, and unlock human capital growth. Without reliable access to electricity, the holes in a country’s social fabric can grow bigger, those without access growing disenchanted with inequality.  

Tackling the Africa region’s energy access crisis requires four bold approaches. 

First, this involves making utilities financially viable. Many power providers in the region are cash-strapped, operate dilapidated and aging generation fleet and infrastructure. Therefore, they can’t deliver reliable and affordable electricity to their customers, let alone deliver electricity to those that currently must rely on inadequate alternatives to electricity. Overall, fewer than half of the utilities in Sub-Saharan Africa recover their operating costs, resulting in GDP losses as high as four percent in some countries.

Improving the performance of national utilities and greening their power generation mix is a prerequisite to lowering the costs of supply, thus expanding electricity access to those currently unelectrified, usually lower-income and often remote households. 

In that effort — and this a critical second point — West and Central African countries need to look beyond their borders and further integrate their national utilities and grids to other systems in the region. The region has an abundance of affordable clean energy sources — hydropower in Guinea, Mali, and Cote d’Ivoire; high solar irradiation in the Sahel — but the regional energy market is fragmented. 

Without efficient regional trade, many countries are highly dependent on one or two energy resources and heavily reliant on inefficient, polluting generation sources, requiring fuel imports linked to volatile international oil prices.

The vision of an integrated regional power market in countries of the Economic Community of West African States (ECOWAS) is coming a step closer to reality thanks to an ambitious program of cross-border interconnection projects. If countries take full advantage of this grid, the share of the region’s electricity consumption traded across borders would more than double from 8 percent today to about 17 percent by 2030. Overall, regional power trade could lower the lifecycle cost of West Africa’s power generation system by about 10 percent and provide greener energy by 2030. 

Third, electrification efforts need to be open to private sector investments and innovations, such as renewables like solar energy and battery storage, which have made a tremendous impact in enabling access for millions of poor and underserved households.  Specifically, off-grid solar systems and mini-grids have become a proven reliable way to provide affordable modern electricity services, powering homes in rural communities, healthcare facilities, and schools.

Burkina Faso, which enjoys one of the best solar radiation conditions in the region, is a successful example of leveraging the transformative impact of solar energy and battery storage. With support from the World Bank, the country is deploying solar energy to power its national grid, as well as mini-grids and individual household systems. Solar power with battery storage is competitive in Burkina Faso compared to other technologies and its government was successful in attracting private sector investments to support this technology.

Last, achieving universal electricity access will involve significant commitment from political leaders, especially developing policies and regulations that can attract high-quality investments.  

A significant step in that direction was achieved at the World Bank’s 2020 Annual Meetings with a commitment to set up the Powering Transformation Platform in each African country. Through the platform, each government will set their country-specific vision, goals and metrics, track progress, and explore and exchange innovative ideas and emerging best practices according to their own national energy needs and plans. 

This platform will bring together the elements needed to bring electricity to all in West and Central Africa and help attract new financing.

Over the last 3 years, the World Bank has doubled its investments to increase electricity access rates in Central and West Africa.  We have committed more than $7.8 billion to support 40 electricity access programs, of which more than half directly support new electricity connections. These operations are expected to provide access to 16 million people. The aim is to increase electricity access rates in West and Central Africa from 50 percent today to 64 percent by 2026.

However, World Bank’s financing alone is not enough. Our estimates show that nearly $20 billion are required for universal electrification across Sub-Saharan Africa, aligning with calls to quadruple power investment to meet demand, with about $10 billion annually needed for West and Central Africa. 

Closing the funding gap will require mobilizing traditional and new partners, especially the private sector, which is willing to invest if enabling conditions are in place, as well as philanthropic capital, that can fill in the space in areas not yet commercially attractive. The World Bank is ready to play a catalytical role in leveraging new investments. 

This is vital as less than a decade remains to reach the 2030 SDG7 goal of ensuring electricity for all through affordable, reliable, and modern energy services. As headlines worldwide focus on soaring energy prices in the developed world, we cannot lose sight of the vast populations in Africa that still cannot access basic energy services. This is the true global energy crisis.

Minnesota 100% Carbon-Free Electricity advances renewable energy: wind, solar, hydropower, hydrogen, biogas from landfill gas and anaerobic digestion; excludes incineration in environmental justice areas; uses renewable energy credits and streamlined permitting.

Key Points

Minnesota's mandate requires utilities to deliver 100% carbon-free power by 2040 with targets and EJ safeguards.

✅ Utilities must hit 90% carbon-free by 2035; 100% by 2040.

✅ Incineration in EJ areas excluded; biogas, wind, solar allowed.

✅ Compliance via renewable credits; streamlined permitting.

Minnesota Gov. Tim Walz, D, is expected to soon sign a bill establishing a clean electricity standard requiring utilities in the state to provide electricity from 100% carbon-free sources by 2040. The bill also calls for utilities to generate at least 55% of their electricity from renewable energy sources by 2035, a trajectory similar to New Mexico's clean electricity push underway this decade.

Electricity generated from landfill gas and anaerobic digestion are named as approved renewable energy technologies, but electricity generated from incinerators operating in “environmental justice areas”, reflecting concerns about renewable facilities violating pollution rules in some states, will not be counted toward the goal. Wind, solar, and certain hydropower and hydrogen energy sources are also considered renewable in the bill. 

The bill defines EJ areas as places where at least 40% of residents are not white, 35% of households have an income that’s below 200% of the federal poverty line, and 40% or more of residents over age 5 have “limited” English proficiency. Areas the U.S. state defines as “Indian country” are also considered EJ areas.

Some of the state’s largest electric utilities, like Xcel Energy and Minnesota Power, have already pledged to move to carbon-free energy, and utilities such as Alliant Energy have outlined carbon-neutral plans in the region, but this bill speeds up that goal by 10 years, Minnesota Public Radio reported. The bill calls for public utilities operating in the state to be 80% carbon-free and other electric utilities to be 60% carbon-free by 2030. All utilities must be 90% carbon-free by 2035 before ultimately hitting the 100% mark in 2040, according to the bill.  

The bill gives utilities some leniency if they demonstrate to state regulators that they can’t offer affordable power while working toward the benchmarks, acknowledging reliability challenges seen in places like California's grid during the clean energy transition. It also allows utilities to buy renewable energy credits to meet the standard instead of generating the energy themselves. 

Patrick Serfass, executive director of the American Biogas Council, said the bill will incentivize more biogas-related electricity projects, “which means the recycling of more organic material and more renewable electricity in the state. Those are all good things,” he said. ABC sees significant potential for biogas production in Minnesota, though the federal climate law has delivered mixed results for accelerating clean power deployment.

The bill also aims to streamline the permitting process for new energy projects in the state, even as some states consider limits on clean energy that would constrain utility use, and calls for higher minimum wage requirements for workers.

US Summer Grid Blackout Risk: NERC and FERC warn of strained reliability as drought, heat waves, and transmission constraints hit MISO, hydro, and renewables, elevating blackout exposure and highlighting demand response and storage solutions.

Key Points

A forecast of summer power shortfalls across the US grid, driven by heat, drought, transmission limits, and a changing resource mix.

✅ NERC and FERC warn of elevated blackout risk and reliability gaps.

✅ MISO region strained by drought, heat, and limited hydro.

✅ Mitigations: demand response, storage, and stronger transmission.

Just when it didn’t seem things couldn’t get worse — gasoline at $5 to $8 a gallon, supply shortages in everything from baby formula to new cars — comes the devastating news that many of us will endure electricity blackouts this summer, and that the U.S. has more blackouts than other developed nations according to one study.

The alarm was sounded by the nonprofit North American Electric Reliability Corp. and the Federal Energy Regulatory Commission, following a recent power grid report card highlighting vulnerabilities.

The North American electric grid is the largest machine on earth and the most complex, incorporating everything from the wonky pole you see at the roadside with a bird’s nest of wires to some of the most sophisticated engineering ever devised. It runs in real-time, even more so than the air traffic control system: All the airplanes in the sky don’t have to land at the same time, but electricity must be there at the flick of every switch.

Except it may not always be there this summer. Rod Kuckro, a respected energy journalist, says it depends on Mother Nature, with extreme weather impacts increasingly straining the grid, but the prognosis isn’t good.

Speaking on “White House Chronicle,” the weekly news and public affairs program on PBS that I host and produce, Kuckro said: “There is a confluence of factors that could affect energy supply across the majority of the (lower) 48 states. These are continued reduced hydroelectric production in the West, and the continued drought in the Southwest.”

The biggest threat to power supply, according to the NERC and the FERC, is in the vast central region, reaching from Manitoba in Canada, where grids are increasingly exposed to harsh weather in recent years, down to the Gulf of Mexico. It is served by the regional transmission organization, the Midcontinent Independent System Operator.

These operational entities are nonprofit companies that organize and distribute their regions’ bulk power for utilities. In California, it is the California Independent System Operator, working to keep the lights on as the state enters a new energy era; in the Mid-Atlantic, it is PJM; and in the Northeast, it is the New England System Independent Operator. They generate no power, but they control power flows and could initiate brownouts and blackouts.

With record storm activity and high temperatures predicted this summer, blackouts are likely to be deadly. The old, the young and the sick are all vulnerable. If the electric supply fails, with it goes everything from air conditioning to refrigeration to lights and even the ability to pump gas or access money from ATMs.

The United States, along with other modern nations, runs on electricity and when that falls short, it is catastrophic. It is chaos writ large, especially if the failure lasts more than a few hours.

On the same episode of “White House Chronicle,” Daniel Brooks, vice president of integrated grid and energy systems at the Electric Power Research Institute, also referred to a “confluence of factors” contributing to the impending electricity crisis. Brooks said, “We’re going through a significant change in terms of the energy mix and resources, and the way those resources behave under certain weather conditions.”

If power supply is stressed this summer, change in the generating mix will get a lot of political attention. At heart is the switch from fossil fuel generation to renewables. If there are power outages, a political storm will ensue. The Biden administration will be accused of speeding the switch to renewables, although the utilities don’t say that.

The weather is deteriorating, and, as experts note, the grid’s biggest challenge isn’t demand but climate change pressures that compound risks, and the grid is stretched in dealing with new realities as well as coping with old bugaboos, like the extreme difficulty in building transmission lines. Better transmission would relieve a lot of grid stress.

Peter Londa, president of Tantalus Systems, which helps its 260 utility customers digitize and cope with the new realities, explained some of the difficulties facing the utilities not only in the shifting sources of generation but also in the new shape of the electric demand. For example, he said, electric vehicles, particularly the much-awaited Ford F-150 Lightning pickup, could be an asset to homeowners and utilities, as California increasingly turns to batteries to stabilize its grid. During a blackout, their EVs could be used to power their homes for days. They could be a source of storage if thousands of owners signed up with their utilities in a storage program.

The fact is that utilities are facing three major shifts: in the generation to wind and solar, in customer demand, and especially in weather. Mother Nature is on a rampage and we all must adjust to that.

Arc One Electric Speedboat delivers zero-emission performance, quiet operation, and reduced maintenance, leveraging battery propulsion, aerospace engineering, and venture-backed innovation to cut noise pollution, fuel costs, and water contamination in high-performance marine recreation.

Key Points

Arc One Electric Speedboat is a battery-powered, zero-emission craft offering quiet, high-performance marine cruising.

✅ 475 hp, 24 ft hull, about 40 mph top speed

✅ Cuts noise, fumes, and water contamination vs gas boats

✅ Backed by Andreessen Horowitz; ex-SpaceX engineers

A team of former SpaceX rocket engineers have joined the race to build the first commercial electric speedboat.

The Arc Boat company announced it had raised $4.25m (£3m) in seed funding to start work on a 24ft 475-horsepower craft that will cost about $300,000.

The LA-based company, which is backed by venture capital firm Andreessen Horowitz (an early backer of Facebook and Airbnb), said the first model of the Arc One boat would be available for sale by the end of the year.

Mitch Lee, Arc’s chief executive, said he wanted to build electric boats because of the impact conventional petrol- or diesel-powered boats have on the environment.

“They not only get just two miles to the gallon, they also pump a lot of those fumes into the water,” Lee said. “In addition, there is the huge noise pollution factor [of conventional boats] and that is awful for the marine life. With gas-powered boats it’s not just carbon emissions into the air, it’s also polluting the water and causing noise pollution. Electric boats, like electric ships clearing the air on the B.C. coast, eliminate all that.”

Lee said electric vessels would also reduce the hassle of boat ownership. “I love being out on the water, being on a boat is so much fun, but owning a boat is so awful,” he said. “I have always believed that electric boats make sense. They will be quicker, quieter and way cheaper and easier to operate and maintain, with access options like an electric boat club in Seattle lowering barriers for newcomers.”

While the first models will be very expensive, Lee said the cost was mostly in developing the technology and cheaper versions would be available in the future, mirroring advances in electric aviation seen across the industry. “It is very much the Tesla approach – we are starting up market and using that income to finance research and development and work our way down market,” he said.

Lee said the technology could be applied to larger craft, and even ferries could run on electricity in the future, as projects for battery-electric high-speed ferries begin to scale.

“We started in February with no team, no money and no warehouse,” he said. “By December we are going to be selling the Arc One, and we are hiring aggressively because we want to accelerate the adoption of electric boats across a whole range of craft, including an electric-ready ferry on Kootenay Lake.”

Lee founded the company with fellow mechanical engineer Ryan Cook. Cook, the company’s chief technology officer, was previously the lead mechanical engineer at Elon Musk’s space exploration company SpaceX where he worked on the Falcon 9 rocket, the world’s first orbital class reusable rocket. In parallel, Harbour Air's electric aircraft highlights cross-sector electrification. Apart from Lee, all of Arc’s employees have some experience working at SpaceX.

The Arc boat, which would have a top speed of 40 mph, joins a number of startups rushing to make the first large-scale production of electric-powered speedboats, while a Vancouver seaplane airline demonstrates complementary progress with a prototype electric aircraft. The Monaco Yacht Club this month held a competition for electric boat prototypes to “instigate a new vision and promote all positive approaches to bring yachting into line” with global carbon dioxide emission reduction targets. Sweden’s Candela C-7 hydrofoil boat was crowned the fastest electric vessel.

Louisiana Grid Rebuild After Hurricane Laura will overhaul transmission lines and distribution networks in Lake Charles, as Entergy restores power after catastrophic outages, replacing poles, transformers, and spans to stabilize critical electric infrastructure.

Key Points

Entergy's project replacing transmission and distribution in Lake Charles to restore power after the Cat 4 storm

✅ 1,000+ transmission structures and 6,637 poles damaged

✅ Entergy targets first energized line into Lake Charles in 2 weeks

✅ Full rebuild of Calcasieu and Cameron lines will take weeks

The main power utility for southwest Louisiana will need to "rebuild" the region's grid after Hurricane Laura blasted the region with 150 mph winds last week, top officials said.

The Category 4 hurricane made landfall last Thursday just south of Lake Charles near Cameron, damaging or destroying thousands of electric poles as well as leaving "catastrophic damages" to the transmission system for southwest Louisiana, similar to impacts seen during Typhoon Mangkhut outages in Hong Kong that left many without electricity.

“This is not a restoration," Entergy Louisiana president and CEO Phillip May said in a statement. "It’s almost a complete rebuild of our transmission and distribution system that serves Calcasieu and Cameron parishes.”

According to Entergy, all nine transmission lines that deliver power into the Lake Charles area are currently out service due to storm damage to multiple structures and spans of wire.

The transmission system is a critical component in the delivery of power to customers’ homes, and failures at substations can trigger large outages, as seen in Los Angeles station fire outage reported recently, according to the company.

Of those structures impacted, many were damaged "beyond repair" and require complete replacement.

Entergy said the damage in southwest Louisiana includes 1,000 transmission structures, 6,637 broken poles, 2,926 transformers and 338 miles of downed distribution wire, highlighting why proactive reliability investments in Hamilton are being pursued by other utilities.

Some 8,300 workers are now in the area working to rebuild the transmission lines, but Entergy said that it will be about two to three weeks before power is available to customers in the Lake Charles area, a timeline similar to Tennessee outages after severe storms reported recently in other states.

"Restoring power will take longer to customers in inaccessible areas of the region," the company said. "While not impacting the expected restoration of service to residential customers, initial estimates are it will take weeks to rebuild all transmission lines in Calcasieu and Cameron parishes."

Entergy Louisiana expects to energize the first of its transmission lines into Lake Charles in two weeks.

“We understand going without power for this extended period will be challenging, and this is not the news customers want to hear. But we have thousands of workers dedicated to rebuilding our grid as quickly as they safely can to return some normalcy to our customers’ lives,” May said.

According to power outage tracking website poweroutage.us, over 164,000 customers remain without service in Louisiana as of Thursday morning, while a Carolinas outage update shows hundreds of thousands affected there as well.

On Wednesday, the Edison Electric Institute, the association of investor-owned electric companies in the U.S., said in a statement to FOX Business that electricity has been restored to approximately 737,000 customers, or 75% of those impacted by the storm across Louisiana, eastern Texas, Mississippi, and Arkansas, even as utilities adapt to climate change to improve resilience.

At least 29,000 workers from 29 states, the District of Columbia and Canada are working to restore power in the region, according to the Electricity Subsector Coordinating Council (ESCC), which is coordinating efforts from government and power industry.

“The transmission loss in Louisiana is significant, with more than 1,000 transmission structures damaged or destroyed by the storm," Department of Energy (DOE) Deputy Secretary Mark Menezes said in a statement. Rebuilding the transmission system is essential to the overall restoration effort and will take weeks given the massive scale and complexity of the work. We will continue to coordinate closely to ensure the full capabilities of the industry and government are marshaled to rebuild this critical infrastructure as quickly as possible.” 

At least 17 deaths in Louisiana have been attributed to the storm; more than half of those killed by carbon monoxide poisoning from the unsafe operation of generators, and residents are urged to follow generator safety tips to reduce these risks. Two additional deaths were verified on Wednesday in Beauregard Parish, which health officials said were due to heat-related illness following the storm.
