Uzbekistan is about to pull the plug on its neighbors.

The authoritarian nation says it will withdraw from the Soviet-era power grid that unites four Central Asian countries, prompting fears of electricity shortages that could make for a winter of hardship in impoverished Tajikistan and Kyrgyzstan.

Each country in the region contributes to the area's power supply and draws electricity from the same system. Their contributions shift as seasons change, because some are hydropower producers that have excess capacity after the spring snowmelt, while others use coal and gas.

Uzbekistan's plan to stop all power flowing in and out of neighboring countries along its transmission lines is expected to deplete overall supplies in the other nations and in some cases cut off entire areas fed by lines leading from Uzbekistan.

Snaking Soviet-era borders left Central Asian nations deeply intertwined and interdependent after Moscow's empire fell apart in 1991.

Wealthier Uzbekistan accuses Tajikistan of stealing electricity and says continued participation in the unreliable Central Asian power grid imperils electricity supplies to its factories and households. It has spent more than $1 billion building a new transmission route designed to enable it to transport electricity to its southern provinces without relying on neighbors' lines.

"The way the Central Asia unified energy system currently works contains a real threat to the stability and safety of Uzbekistan's own power system," the chief of Uzbek state utility company Uzbekenergo's dispatch center, Esso Sadullayev, said in a government-run newspaper. The company claimed Tajikistan had illegally appropriated some 100 million kilowatt hours from the system since late last year.

"Uzbekenergo sees no possibility of continuing to operate" in the grid, he said.

In Tajikistan and Kyrgyzstan, the planned pullout has prompted fears of crippling power shortages and a repeat of the trials many faced two winters ago, when blistering cold disrupted electricity production and claimed hundreds of lives. Many in the region live in Soviet-era apartments that are poorly equipped to protect dwellers from harsh winter weather.

Because of the geography of the grid and the twisting national borders, Uzbekistan's withdrawal threatens to cut off some southern districts in Kyrgyzstan supplied with electricity from a hydropower plant through lines traversing Uzbek territory.

Tajikistan, meanwhile, says the move will cut it off from gas-rich Turkmenistan, which has committed to deliver 1.2 billion kilowatt hours annually via Uzbekistan over the winter period. Turkmenistan lies west of Uzbekistan and does not border Tajikistan or Kyrgyzstan.

More tension looms in the future. Mountainous Kyrgyzstan and Tajikistan have vast hydropower potential and are both working on ambitious projects that could serve much of their electricity needs, while creating enough surplus for export in the months of peak production. But Uzbekistan, which lies downstream from those proposed dam projects, strenuously objects amid fears that its crucial agricultural heartland could be cut off from precious irrigation water.

Tajik economist Khodzhimuhamad Umarov said Uzbekistan's plans amounted to an energy blockade.

Observers say Uzbekistan's decision to quit the grid could, however, prompt neighboring government to take energy security in into their own hands.

Tajikistan recently unveiled a Chinese-built 500-kilowatt transmission line that will link the northern and central parts of the country, adding to the poor nation's debt to China but reducing reliance on Uzbekistan.

New Mexico Governor to Sign 100% Clean Electricity Bill ‘As Quickly As Possible’

New Mexico Energy Transition Act advances zero-carbon electricity, mandating public utilities deliver carbon-free electricity by 2045, with renewable targets of 50 percent by 2030 and 80 percent by 2040 to accelerate grid decarbonization.

 

Key Points

A state law requiring utilities to deliver carbon-free electricity by 2045, with 2030 and 2040 renewable targets.

✅ 100 percent carbon-free power from utilities by 2045

✅ Interim renewable targets: 50 percent by 2030, 80 percent by 2040

✅ Aligns with clean energy commitments in HI, CA, and DC

 

The New Mexico House of Representatives passed the Energy Transition Act Tuesday afternoon, sending the carbon-free electricity bill, a move aligned with proposals for a Clean Electricity Standard at the federal level, to Gov. Michelle Lujan Grisham.

Her opinions on it are known: she campaigned on raising the share of renewable energy, a priority echoed in many state renewable ambitions nationwide, and endorsed the ETA in a recent column.

"The governor will sign the bill as quickly as possible — we're hoping it is enrolled and engrossed and sent to her desk by Friday," spokesperson Tripp Stelnicki said in an email Tuesday afternoon.

Once signed, the legislation will commit the state to achieving zero-carbon electricity from public utilities by 2045. The bill also imposes interim renewable energy targets of 50 percent by 2030 and 80 percent by 2040, similar to Minnesota's 2040 carbon-free bill in its timeline.

The Senate passed the bill last week, 32-9. The House passed it 43-22.

The legislation would enter New Mexico into the company of Hawaii, California, where climate risks to grid reliability are shaping policy, and Washington, D.C., which have committed to eliminating carbon emissions from their grids. A dozen other states have proposed similar goals. Meanwhile, the Green New Deal resolution has prompted Congress to discuss the bigger task of decarbonizing the nation overall.

Though grid decarbonization has surged in the news cycle in recent months, even as some states consider moves in the opposite direction, such as a Wyoming bill restricting clean energy that would limit utility choices, New Mexico's bill arose from a years-long effort to rally stakeholders within the state's close-knit political community.

ERCOT Issues RFP to Procure Capacity to Alleviate Winter Concerns

ERCOT Winter Capacity RFP seeks up to 3,000 MW through generation and demand response to bolster Texas grid reliability during peak load, leveraging Reliability Must-Run, incentive factors, and EEA risk mitigation for the 2023-24 season.

 

Key Points

An ERCOT initiative to procure 3,000 MW of generation and demand response to reduce EEA risk and improve reliability.

✅ Targets 3,000 MW from generation and demand response

✅ Uses RMR-style contracts with flexible incentive factors

✅ Aims to lower EEA probability below 10% this winter

 

The Electric Reliability Council of Texas (ERCOT) issued a request for proposals to stakeholders to procure up to 3,000 MW of generation or demand response capacity to meet load and reserve requirements during the winter 2023-24 peak load season (Dec. 1, 2023, through Feb. 29, 2024), amid ongoing Texas power grid challenges across the region.

ERCOT cited “several factors, including significant peak load growth since last winter, recent and proposed retirements of dispatchable Generation Resources, and recent extreme winter weather events, including Winter Storm Elliott in December 2022, Winter Storm Uri in February 2021, and the 2018 and 2011 winter storms, each of which resulted in abnormally high demand during winter weather.” It now seeks additional capacity under its “authority to prevent an anticipated Emergency Condition,” reflecting nationwide blackout risks identified by grid experts.

In its notice regarding the RFP, ERCOT identified a number of mothballed and recently decommissioned generation resources that may be eligible to offer capacity under the RFP. It further stated that offers must comport with the format of its “Reliability Must-Run” agreement but could include a proposed “Incentive Factor” that reflects the revenues the unit owners determine would be necessary to bring the unit back to operation. It added that the Incentive Factor is not necessarily limited to 10%. Providers of eligible demand response can submit offers based on similar principles that are not necessarily constrained by cost. The notice identifies potential acceptable sources of demand response, describes certain parameters for the kinds of demand response that are permitted to respond to the RFP, and outlines the time periods during which ERCOT must be able to deploy the demand response resources to improve electricity reliability across the system.

To meet the Dec. 1, 2023, service start date, ERCOT developed an aggressive timeline to solicit and evaluate proposals through the RFP. Responses to the RFP are due Nov. 6, 2023. ERCOT’s schedule provides that it will notify market participants that obtain awards on Nov. 23, 2023. Expect contracts to be executed by Nov. 30, 2023.

Unlike Regional Transmission Organizations in the Northeastern United States, ERCOT does not have a capacity market. Instead, ERCOT relies on a high price cap of $5,000 per MWh for its energy market (decreased from the $9,000 per MWh cap in effect during Winter Storm Uri) and an Operating Reserve Demand Curve adder that pays additional funds to generators supplying power and ancillary services, an area recently scrutinized for improper payments when supply conditions are tight. In the wake of Winter Storm Uri, some calls were made to have ERCOT adopt a capacity market for reliability reasons, and a number of legal battles continue to play out in the wake of Winter Storm Uri. (See recent McGuireWoods legal alert “Winter Storm Uri Power Dispute Reaches the Supreme Court of Texas.”) Though a capacity market was not adopted, the Texas Legislature approved a $7.2 billion loan program, widely described as an electricity market bailout for generators, to build up to 10,000 MW of dispatchable generation. The legislature also approved a version of the Public Utility Commission of Texas’ proposal to establish a “Performance Credit Mechanism,” but with a cost cap of $1 billion.

The loss of life and economic impacts of Winter Storm Uri in 2021, along with the energy crunches and calls for conservation this past summer, are driving changes to ERCOT’s “energy-only” market, including electricity market reforms under consideration. Texas policymakers are providing multiple financial incentives to promote investment in dispatchable on-demand generation, and voters will consider funding to modernize generation measures this year to make the Texas grid more reliable and able to deal with power demand from a growing economy and increased demand for electricity driven by weather. In the meantime, ERCOT’s plan to procure 3,000 MW through this RFP process is a stopgap measure intended to bolster reliability for the upcoming winter season and lower the probability of load shed in the event of severe winter weather.

Cheap at Last, Batteries Are Making a Solar Dream Come True

Solar Plus Storage is accelerating across utilities and microgrids, pairing rooftop solar with lithium-ion batteries to enhance grid resilience, reduce peak costs, prevent blackouts, and leverage tax credits amid falling prices and decarbonization goals.

 

Key Points

Solar Plus Storage combines solar generation with batteries to shift load, boost reliability, and cut energy costs.

✅ Cuts peak demand charges and enhances blackout resilience

✅ Falling battery and solar costs drive nationwide utility adoption

✅ Enables microgrids and grid services like frequency regulation

 

Todd Karin was prepared when California’s largest utility shut off power to millions of people to avoid the risk of wildfires last month. He’s got rooftop solar panels connected to a single Tesla Powerwall in his rural home near Fairfield, California. “We had backup power the whole time,” Karin says. “We ran the fridge and watched movies.”

Californians worried about an insecure energy future are increasingly looking to this kind of solution. Karin, a 31-year-old postdoctoral fellow at Lawrence Berkeley National Laboratory, spent just under $4,000 for his battery by taking advantage of tax credits. He's also saving money by discharging the battery on weekday evenings, when energy is more expensive during peak demand periods. He expects to save around $1,500 over the 10 years the battery is under warranty.

The economics don’t yet work for every household, but the green-power combo of solar panels plus batteries is popping up on a much bigger scale in some unexpected places. Owners of a rice processing plant in Arkansas are building a system to generate 26 megawatts of solar power and store another 40 MW. The plant will cut its power bill by a third, and owners say they will pass the savings to local rice growers. New York’s JFK Airport is installing solar plus storage to reduce its power load by 10 percent, while Pittsburgh International Airport is building a 20-MW solar and natural gas microgrid to keep it independent from the local utility. Officials at both airports are worried about recent power shutdowns due to weather and overload-related blackouts.

And residents of the tiny northern Missouri town of Green City (pop. 608) are getting 2.5 MW of solar plus four hours of battery storage from the state’s public utility next year. The solar power won’t go directly to townspeople, but instead will back up the town’s substation, reducing the risk of a potential shutdown. It’s part of a $68 million project to improve the reliability of remote substations far from electric generating stations.

“It’s a pretty big deal for us,” says Chad Raley, who manages technology and renewables at Ameren, a Missouri utility that is building three rural solar-plus-storage projects to better manage the flow of electricity across the local grid. “It gives us so much flexibility with renewable generation. We can’t control the sun or clouds or wind, but we can have battery storage.”

The first solar-plus-storage installations started about a decade ago on a small scale in sunny states like California, Hawaii, and Arizona. Now they’re spreading across the country, driven by falling prices of both solar panels and lithium-ion batteries the size of a shipping container imported from both China and South Korea, with wind, solar, and batteries making up most of the utility-scale pipeline nationwide. These countries have ramped up production efficiencies and lowered labor costs, leaving many US manufacturers in the dust. In fact, the price of building a comparable solar-plus-storage generating facility is now cheaper than operating a coal-fired power plant, industry officials say. In certain circumstances, the cost is equal to some natural gas plants.

“This is not just a California, New York, Massachusetts thing,” says Kelly Speakes-Backman, CEO of the Energy Storage Association, an industry group in Washington. She says more than 30 states have renewable storage on the grid. Utilities have proposed and states have approved 7 gigawatts to be installed by 2030, and most new storage will be paired with solar across the US.

Speakes-Backman estimates the unit cost of electricity produced from a solar-plus-storage system will drop 10 to 15 percent each year through 2024, supporting record growth in solar and storage investments. “If you have the option of putting out a polluting or non-polluting generating source at the same price, what are you going to pick?” says Speakes-Backman.

She notes that PJM, a large Mid-Atlantic wholesale grid operator, announced it will deploy battery storage to help smooth out fluctuating power from two wind farms it operates. “When the grid fluctuates, storage can react to it quickly and can level out the supply,” she says. In the Midwest, grid-level battery storage is also being used to absorb extra wind power. Batteries hold onto the wind and put it back onto the grid when people need it.

While the solar-plus-storage trend isn’t yet putting a huge dent in our fossil fuel use, according to Paul Denholm, an energy analyst at the National Renewable Energy Laboratory in Golden, Colorado, it is a good beginning and has the side effect of cutting air pollution. By 2021, solar and other renewable energy sources will overtake coal as a source of energy, and the US is moving toward 30% electricity from wind and solar, according to a new report by the Institute for Energy Economics and Financial Analysis, a nonprofit think tank based in Cleveland.

That’s a glimmer of hope in a somewhat dreary week of news on carbon emissions. A new United Nations report released this week finds that the planet is on track to warm by 3.9 degrees Celsius (7 Fahrenheit) by 2100 unless drastic cuts are made by phasing out gas-powered cars, eliminating new coal-fired power plants, and changing how we grow and manage land, and scientists are working to improve solar and wind power to limit climate change as well.

Energy-related greenhouse gas emissions in the US rose 2.7 percent in 2018 after several years of decline. The Trump administration has rolled back climate policies from the Obama years, including withdrawing from the Paris climate accords.

There may be hope from green power initiatives outside the Beltway, though, and from federal proposals like a tenfold increase in US solar that could remake the electricity system. Arizona plans to boost solar-plus-storage from today’s 6 MW to a whopping 850 MW by 2025, more than the entire capacity of large-scale batteries in the US today. And some folks might be cheering the closing of the West’s biggest coal-fired power plant, the 2.25-gigawatt Navajo Generating Station, in Arizona, which had spewed soot and carbon dioxide over the region for 45 years until last week. The closure might help the planet and clear the hazy smog over the Grand Canyon.

Is Ontario embracing clean power?

Ontario Clean Energy Expansion signals IESO-backed renewables, energy storage, and low-CO2 power to meet EV-driven demand, offset Pickering nuclear retirement, and balance interim gas-fired generation while advancing grid reliability, decarbonization, and net-zero targets.

 

Key Points

Ontario Clean Energy Expansion plans to grow renewables and storage, manage short-term gas, and meet rising demand.

✅ IESO long-term procurements for renewables and storage

✅ Interim reliance on gas to replace Pickering capacity

✅ Targets align with net-zero grid reliability goals

 

After cancelling hundreds of renewable power projects four years ago, the Doug Ford government appears set to expand clean energy to meet a looming electricity shortfall across the province.

Recent announcements from Ontario Energy Minister Todd Smith and the province’s electric grid management agency suggest the province plans to expand low-CO2 electricity with new wind and solar plans in the long-term, even as it ramps up gas-fired power over the next five years.

The moves are in response to an impending electricity shortfall as climate-conscious drivers switch to electric vehicles, farmers replace field crops with greenhouses and companies like ArcelorMittal Dofasco in Hamilton switch from CO2-heavy manufacturing to electricity-based production. Forecasters predict Canada will need to double its power supply by 2050.

While Ontario has a relatively low-CO2 power system, the province’s electricity supply will be reduced in 2025 when Ontario Power Generation closes the 50-year-old Pickering nuclear station, now near the end of its operating life. This will remove 3,100 megawatts of low-CO2 generation, about eight per cent of the province’s 40,000-megawatt total.

The impending closure has created a difficult situation for the Independent Electricity System Operator (IESO), the provincial agency managing Ontario’s grid. Last year, it forecasted it would need to sharply increase CO2-polluting natural gas-fired power to avoid widespread blackouts.

This would mean drivers switching to electric vehicles or companies like Dofasco cutting CO2 through electrification would end up causing higher power system emissions.

It would also fly in the face of the federal government’s ambition to create a net-zero national electricity system by 2035, a critical part of Canada’s pledge to reduce CO2 emissions to zero by 2050.

Yet the Ford government has appeared reluctant to expand clean energy. In the 2018 election, clean electricity was a key issue as it appealed to anti-turbine voters in rural Ontario and cancelled more than 700 renewable energy contracts shortly after taking office, taking 400 megawatts out of the system.

But there are signs the government is having a change of heart. IESO recently released a list of 55 companies approved to submit bids for 3,500 megawatts of long-term electricity contracts starting between 2025 and 2027, and the energy minister has outlined a plan to address growing energy needs as well.

The companies include a variety of potential producers, ranging from Canadian and global renewable companies to local utilities and small startups. Most are renewable power or energy storage companies specializing in low- or zero-emission power. IESO plans additional long-term bid offerings in the future.

This doesn’t mean gas generation will be turned off. IESO will contract yearly production from existing gas plants until 2028 (the annual contract in 2023 will be for about 2,000 megawatts). As well, IESO has issued contracts to four gas-fired producers, a small wind company and a storage company to begin production of about 700 megawatts to boost gas plant output starting between 2024 and 2026.

While this represents an expansion of existing gas-fired generation, Smith has asked IESO to report on a gas moratorium, saying he doesn’t believe new gas plants will be needed over the long term.

The NDP and Greens criticized the government for relying on gas in the near term. But clean energy advocates greeted the long-term plans positively.

The IESO process “will contribute to a clean, reliable and affordable grid,” said the Canadian Renewable Energy Association.

Rachel Doran, director of policy and strategy at Clean Energy Canada, said in an email the potential gas generation moratorium “is an encouraging step forward,” although she criticized the “unfortunate decision to replace near-term nuclear power capacity with climate-change-causing natural gas.”

There will have to be a massive clean energy expansion to green Ontario’s grid well beyond what has been announced in recent days for Ontario to meet its future energy needs (think a doubling of Ontario’s current 40,000-megawatt capacity by 2050).

But these first steps hold promise that Ontario is at least starting on the path to that goal, rather than scrambling to keep the lights on with CO2-polluting natural gas.

Latvia eyes electricity from Belarus nuclear plant

Latvia Astravets electricity imports weigh AST purchases from the Belarusian nuclear plant, impacting the Baltic grid, Lithuania market, energy security, and cross-border trading as Latvia seeks to mitigate supply risks and stabilize power flows.

 

Key Points

Proposed AST purchases of power from Belarus's Astravets plant to bolster Baltic grid supply via Lithuania.

✅ AST evaluates imports to mitigate supply risk

✅ Energy could enter Lithuania via existing trading route

✅ Debate centers on nuclear safety and Baltic grid impacts

 

Latvia’s electricity transmission system operator, AST, is looking at the possibility of purchasing electricity from the soon-to-be completed Belarusian nuclear power plant in Astravets, at a time when Ukraine's electricity exports have resumed in the region, long criticised by the Lithuanian government, Belsat TV has reported.

According to the Latvian media, the Latvian government is seeking to mitigate the risk of a possible drop in electricity supplies amid price spikes in Ireland highlighting dispatchable power concerns, given that energy trading between the Baltic states and third parties is currently carried out only through the Belarusian-Lithuanian border, including Latvian imports from Lithuania.

If AST starts importing electricity from the Belarusian plant to Latvia, in a pattern similar to Georgia's electricity imports during peak demand, the energy is expected to enter the Lithuanian market as well.

Such cross-border flows also mirror responses to Central Asia's electricity shortages seen recently.

The Lithuanian government has repeatedly criticised the nuclear power over national security and environmental safety concerns, as well as a number of emergencies that took place during construction, particularly as Europe is losing nuclear power and confronting energy security challenges.

Debates over infrastructure and safety have also intensified by projects like power lines to reactivate Zaporizhzhia in Ukraine.

The first Astravets reactor, which is being built close to the Lithuanian border in the Hrodno region, is expected to be operational by the end of 2019, a year that saw Belgium's nuclear exports rise across Europe.

Neo-Nazi, woman accused of plotting 'hate-fueled attacks' on power stations, federal complaint says

Baltimore Substation Attack Plot highlights alleged neo-Nazi plans targeting electrical substations and the power grid, as FBI and DHS warn of domestic extremism threats to critical infrastructure, with arrests in Maryland disrupting potential sniper attacks.

 

Key Points

An alleged extremist plot to disable Baltimore's power grid by shooting substations, thwarted by federal arrests.

✅ Two suspects charged in Maryland conspiracy

✅ Targets included five substations around Baltimore

✅ FBI cites domestic extremism threat to infrastructure

 

A neo-Nazi in Florida and a Maryland woman conspired to attack several electrical substations in the Baltimore area, federal officials say.

Sarah Beth Clendaniel and Brandon Clint Russell were arrested and charged in a conspiracy to disable the power grid by shooting out substations via "sniper attacks," according to a criminal complaint from the U.S. Attorney's Office for the District of Maryland.

Clendaniel allegedly said she wanted to "completely destroy this whole city" and was planning to target five substations situated in a "ring" around Baltimore, the complaint said. Russell is part of a violent extremist group that has cells in multiple states, and he previously planned to attack critical infrastructure in Florida, the complaint said.

"This planned attack threatened lives and would have left thousands of Marylanders in the cold and dark," Maryland U.S. Attorney Erek Barron said in a press release. "We are united and committed to using every legal means necessary to disrupt violence, including hate-fueled attacks."

The news comes as concerns grow about an increase in targeted substation attacks on U.S. substations tied to domestic extremism.

 

What to know about substation attacks

Federal data shows vandalism and suspicious activities at electrical facilities soared nationwide last year, and cyber actors have accessed utilities' control rooms as well.

At the end of the year, attacks or potential attacks were reported on more than a dozen substations and one power plant across five states, and Symantec documented Russia-linked Dragonfly activity targeting the energy sector earlier. Several involved firearms.

In December, targeted attacks on substations in North Carolina left tens of thousands without power amid freezing temperatures, spurring renewed focus on protecting the U.S. power grid among officials. The FBI is investigating.

Vandalism at facilities in Washington left more than 21,000 without electricity on Christmas Day, even as hackers breached power-plant systems in other states. Two men were arrested, and one told police he planned to disrupt power to commit a burglary.

The Department of Homeland Security last year said domestic extremists had been developing "credible, specific plans" since at least 2020 and would continue to "encourage physical attacks against electrical infrastructure," and the U.S. government has condemned Russia for power grid hacking as well.

Last February, three neo-Nazis pleaded guilty to federal crimes related to a scheme to attack the grid with rifles, with each targeting a substation in a different region of the U.S., even as reports that Russians hacked into US electric utilities drew widespread attention.
