Korea to bankroll “smart” Chicago buildings

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”

Tesla Energy Ventures Texas enters the deregulated market as a retail electricity provider, leveraging ERCOT, battery storage, solar, and grid software to enable virtual power plants and customer energy trading with Powerwall and Megapack assets.

Key Points

Tesla Energy Ventures Texas is Tesla's retail power unit selling grid and battery energy and enabling solar exports.

✅ ERCOT retail provider; sells grid and battery-stored power

✅ Uses Powerwall/Megapack; supports virtual power plants

✅ Targets Tesla owners; enables solar export and trading

Last week, Tesla Energy Ventures, a new subsidiary of electric car maker Tesla Inc. (TSLA), filed an application to become a retail electricity provider in the state of Texas. According to reports, the company plans to sell electricity drawn from the grid to customers and from its battery storage products. Its grid transaction software may also enable customers for its solar panels to sell excess electricity back to the smart grid in Texas.1

For those who have been following Tesla's fortunes in the electric car industry, the Palo Alto, California-based company's filing may seem baffling. But the move dovetails with Tesla's overall ambitions for its renewable energy business, as utilities face federal scrutiny of climate goals and electricity rates.

Why Does Tesla Want to Become an Electricity Provider?
The simple answer to that question is that Tesla already manufactures devices that produce and store power. Examples of such devices are its electric cars, which come equipped with lithium ion batteries, and its suite of battery storage products for homes and enterprises. Selling power generated from these devices to consumers or to the grid is a logical next step.

Tesla's move will benefit its operations. The filing states that it plans to build a massive battery storage plant near its manufacturing facility in Austin. The plant will provide the company with a ready and cheap source of power to make its cars.

Tesla's filing should also be analyzed in the context of the Texas grid. The state's electricity market is fully deregulated, unlike regions debating grid privatization approaches, and generated about a quarter of its overall power from wind and solar in 2020.2 The Biden administration's aggressive push toward clean energy is only expected to increase that share.

After a February fiasco in the state grid resulted in a shutdown of renewable energy sources and skyrocketing natural gas prices, Texas committed to boosting the role of battery storage in its grid. The Electricity Reliability Council of Texas (ERCOT), the state's grid operator, has said it plans to install 3,008 MW of battery storage by the end of 2022, a steep increase from the 225 MW generated at the end of 2020.3 ERCOT's proposed increase in installation represents a massive market for Tesla's battery unit.

Tesla already has considerable experience in this arena. It has built battery storage plants in California and Australia and is building a massive battery storage unit in Houston, according to a June Bloomberg report.4 The unit is expected to service wholesale power producers. Besides this, the company plans to "drum up" business among existing customers for its batteries through an app and a website that will allow them to buy and sell power among themselves, a model also being explored by Octopus Energy in international talks.

Tesla Energy Ventures: A Future Profit Center?
Tesla's foray into becoming a retail electricity provider could boost the top line for its energy services business, even as issues like power theft in India highlight retail market challenges. In its last reported quarter, the company stated that its energy generation and storage business brought in $810 million in revenues.

Analysts have forecast a positive future for its battery storage business. Alex Potter from research firm Piper Sandler wrote last year that battery storage could bring in more than $200 billion per year in revenue and grow up to a third of the company's overall business.5

Immediately after the news was released, Morningstar analyst Travis Miller wrote that Tesla does not represent an immediate threat to other major players in Texas's retail market, where providers face strict notice obligations illustrated when NT Power was penalized for delayed disconnection notices, such as NRG Energy, Inc. (NRG) and Vistra Corp. (VST). According to him, the company will initially target its own customers to "complement" its offerings in electric cars, battery, charging, and solar panels.6

Further down the line, however, Tesla's brand name and resources may work to its advantage. "Tesla's brand name recognition gives it an advantage in a hypercompetitive market," Miller wrote, adding that the car company's entry confirmed the firm's view that consumer technology or telecom companies will try to enter retail energy markets, where policy shifts like Ontario rate reductions can shape customer expectations.

US Utilities Shift From Coal as natural gas stays cheap, renewables like wind and solar scale, Clean Power Plan uncertainty lingers, and investors, state policies, and emissions targets drive generation choices and accelerate retirements.

Key Points

A long-term shift by utilities from coal to cheap natural gas, expanding renewables, and lower-emission generation.

✅ Cheap natural gas undercuts coal on price and flexibility.

✅ Renewables costs falling; wind and solar add competitive capacity.

✅ State policies and investors sustain emissions reductions.

When President Donald Trump signed an executive order last week to sweep away Obama-era climate change regulations, he said it would end America's "war on coal", usher in a new era of energy production and put miners back to work.

But the biggest consumers of U.S. coal - power generating companies - remain unconvinced about efforts to replace Obama's power plant overhaul with a lighter-touch approach.

Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama's administration to block its Clean Power Plan, the main target of Trump's executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump's efforts.

The utilities gave many reasons, mainly economic: Natural gas - coal’s top competitor - is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump's regulatory rollback may not survive legal challenges, as rushed pricing changes draw warnings from energy groups.

Meanwhile, big investors aligned with the global push to fight climate change – such as the Norwegian Sovereign Wealth Fund – have been pressuring U.S. utilities in which they own stakes to cut coal use.

"I’m not going to build new coal plants in today’s environment," said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. "And if I’m not going to build new ones, eventually there won’t be any."

Of the 32 utilities contacted by Reuters, 20 said Trump's order would have no impact on their investment plans; five said they were reviewing the implications of the order; six gave no response. Just one said it would prolong the life of some of its older coal-fired power units.

North Dakota's Basin Electric Power Cooperative was the sole utility to identify an immediate positive impact of Trump's order on the outlook for coal.

"We're in the situation where the executive order takes a lot of pressure off the decisions we had to make in the near term, such as whether to retrofit and retire older coal plants," said Dale Niezwaag, a spokesman for Basin Electric. "But Trump can be a one-termer, so the reprieve out there is short."

Trump's executive order triggered a review aimed at killing the Clean Power Plan and paving the way for the EPA's Affordable Clean Energy rule to replace it, though litigation is ongoing. The Obama-era law would have required states, by 2030, to collectively cut carbon emissions from existing power plants by 30 percent from 2005 levels. It was designed as a primary strategy in U.S. efforts to fight global climate change.

The U.S. coal industry, without increases in domestic demand, would need to rely on export markets for growth. Shipments of U.S. metallurgical coal, used in the production of steel, have recently shown up in China following a two-year hiatus - in part to offset banned shipments from North Korea and temporary delays from cyclone-hit Australian producers.

RETIRING AND RETROFITTING

Coal had been the primary fuel source for U.S. power plants for the last century, but its use has fallen more than a third since 2008 after advancements in drilling technology unlocked new reserves of natural gas.

Hundreds of aging coal-fired power plants have been retired or retrofitted. Huge coal mining companies like Peabody Energy Corp and Arch Coal fell into bankruptcy, and production last year hit its lowest point since 1978.

The slide appears likely to continue: U.S. power companies now expect to retire or convert more than 8,000 megawatts of coal-fired plants in 2017 after shutting almost 13,000 MW last year, according to U.S. Energy Information Administration and Thomson Reuters data.

Luke Popovich, a spokesman for the National Mining Association, acknowledged Trump's efforts would not return the coal industry to its "glory days," but offered some hope.

"There may not be immediate plans for utilities to bring on more coal, but the future is always uncertain in this market," he said.

Many of the companies in the Reuters survey said they had been focused on reducing carbon emissions for a decade or more while tracking 2017 utility trends that reinforce long-term planning, and were hesitant to change direction based on shifting political winds in Washington D.C.

"Utility planning typically takes place over much longer periods than presidential terms of office," Berkshire Hathaway Inc-owned Pacificorp spokesman Tom Gauntt said.

Several utilities also cited falling costs for wind and solar power, which are now often as cheap as coal or natural gas, thanks in part to government subsidies for renewable energy and recent FERC decisions affecting the grid.

In the meantime, activist investors have increased pressure on U.S. utilities to shun coal.

In the last year, Norway's sovereign wealth fund, the world's largest, has excluded more than a dozen U.S. power companies - including Xcel, American Electric Power Co Inc and NRG Energy Inc - from its investments because of their reliance on coal-fired power.

Another eight companies, including Southern Co and NorthWestern Corp, are "under observation" by the fund.

Wyoming-based coal miner Cloud Peak Energy said it doesn't blame utilities for being lukewarm to Trump's order.

"For eight years, if you were a utility running coal, you got the hell kicked out of you," said Richard Reavey, a spokesman for the company. "Are you going to turn around tomorrow and say, 'Let's buy lots of coal plants'? Pretty unlikely."

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.

APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

• Raise thermostat settings to no lower than 80 degrees.
• Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
• Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.

"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."

Community Solar for Low-Income Homes expands energy equity by delivering renewable energy access, predictable bill savings, and tax credit benefits to renters and energy-insecure households, accelerating distributed generation and storage adoption nationwide.

Key Points

A program model enabling renters and LMI households to subscribe to off-site solar and save on utility bills.

✅ Earn bill credits from shared solar generation.

✅ Expands access for renters and LMI subscribers.

✅ Often paired with storage and IRA tax credit adders.

On a square-foot basis, the issue of inequality is made worse by higher costs for energy usage in the nation. Efforts like community solar programs such as Maryland community solar are underway to boost low-income participation in the cost benefits of renewable energy.

The Energy Information Administration (EIA) shows that households that are considered energy insecure, or those that have the inability to adequately meet basic household energy costs, are paying more for electricity than their wealthier counterparts. 

On average in the United States in 2020, households were billed about $1.04 per square foot for all energy sources. For homes that did not report energy insecurity, that average was $0.98 per square foot, while homes with energy insecurity issues paid an average of $1.24 per square foot for energy. This means that U.S. residents that need the most support on their energy bills are stuck with costs 27% higher than their neighbors on square-foot-basis.

EIA said energy-insecure households have reduced or forgone basic necessities to pay energy bills, kept their houses at unsafe temperatures because of energy cost concerns, or been unable to repair heating or cooling equipment because of cost.

In 2020, households with income less than $10,000 a year were billed an average of $1.31 per square foot for energy, while households making $100,000 or more were billed an average of $0.96 per square foot, said EIA. Renters paid considerably more ($1.28 per square foot) than owners ($0.98 per square foot). There were also considerable differences between regions, with New England solar growth sparking grid upgrade debates, ethnic groups and races, and insulation levels, as seen below.

The energy transition toward renewables like solar has offered price stability, amid record solar and storage growth nationwide, but thus far energy-insecure communities have relatively been left behind. A recent Berkeley Lab report, Residential Solar-Adopter Income and Demographic Trends, indicates that even though the rate of solar adoption among low-income residents is increasing (from 5% in 2010 to 11% in 2021), that segment of energy consumers remains under-represented among solar adopters, relative to its share of the population.

Community solar efforts

As such, the United States is targeting communities most impacted by energy costs that have not benefitted from the transition, highlighting “Energy Communities” that are eligible for an additional 10% tax credit through funds made possible by the Inflation Reduction Act.

Additionally, a push for community solar development is taking place nationwide to extend access to affordable solar energy to renters and other residents that aren’t able to leverage finances to invest in predictable, low-cost residential solar systems. The Biden Administration set a goal this year to sign up 5 million community solar households, achieving $1 billion in bill savings by 2025. The community solar model only represents about 8% of the total distributed solar capacity in the nation. This target would entail a jump from 3 GW installed capacity to 20 GW by the target year. The Department of Energy estimates community solar subscribers save an average of 20% on their bills.

California this year passed AB 2316, the Community Renewable Energy Act takes aim at four acute problems in the state’s power market: reliability amid rising outage risks, rates, climate and equity. The law creates a community renewable energy program, including community solar-plus-storage, supported by cheaper batteries, to overcome access barriers for nearly half of Californians who rent or have low incomes. Community solar typically involves customers subscribing to an off-site solar facility, receiving a utility bill credit for the power it generates.

“Community renewable energy is a proven powerful tool to help close California’s clean energy gap, bringing much needed relief to millions struggling with high housing costs and utility debt,” said Alexis Sutterman, energy equity program manager at the California Environmental Justice Alliance.

The program has energy equity baked into its structure, working to make sure Californians of all income levels participate in the benefits of the energy transition. Not only does it open solar access to renters, the law ensures that at least 51% of subscribers are low-income customers, which is expected to make projects eligible for a 10% tax credit adder under the IRA.

“The money’s on the table now,” said Jeff Cramer, president and chief executive of the Coalition for Community Solar Access. “While there are groups pushing for solar access for all, and states with strong legislation, there are other pockets of interest in surprising places in the United States. For example, Louisiana has no policy for community solar or support for low-income residents going solar but the city of New Orleans has its own utility commission with a community solar program. In Nebraska, forward-looking co-operatives have created community solar projects.

Community solar markets are active in 22 states, with more expected to come online in the future as states pursue 100% clean energy targets across the country. However, the market is expected to require strong community outreach efforts to foster trust and gain subscribers.

“There is a distrust of community solar initially in LMI communities as many have been burned before by retail energy false promises,” said Eric LaMora, executive director, community solar, Nautilus Solar on a panel at the Solar Energy Industries Association Finance, Tax, and Buyers seminar. “People are suspicious but there really are no hooks with community solar.”

LMI residents are leery to provide tax records or much documents at all in order to sign up for community solar, LaMora said. “We were surprised to see less of a default rate with LMI residents. We attribute this to the fact that they see significant savings on their electric bill, making it easier to pay each month,” he said.
