The Environmental Protection Agency moved to more tightly control air pollution from large power plants, factories and oil refineries, a step to limit emissions widely blamed for global warming.

The EPA said it is completing a rule requiring large polluters to reduce the amounts of carbon dioxide and other greenhouse gases that they release into the air. Those emissions can boost many allergens and worsen smog, which can trigger asthma attacks and other respiratory ailments.

The rule would require companies to install better technology and improve energy efficiency whenever they build, or significantly modify, a plant.

EPA Administrator Lisa Jackson said the rule applies only to large polluters such as power plants, refineries and cement production facilities that collectively are responsible for 70 percent of greenhouse gas emissions from stationary sources in the United States.

Jackson said the rule sets commonsense standards that will clean the air and protect public health, while avoiding burdensome regulations that could harm farms and small and medium-sized businesses.

"There is no denying our responsibility to protect the planet for our children and grandchildren," she said in a statement. "It's long past time we unleashed our American ingenuity and started building the efficient, prosperous clean energy economy of the future."

The EPA announcement comes a day after an energy and climate bill was introduced in the Senate that seeks to accomplish many of the same goals. But EPA spokesman Brendan Gilfillan denied any connection, saying "rules are ready when they are ready."

The pollution rule will take effect in January, when industrial facilities that already obtain Clean Air Act permits for other pollutants will be required to obtain permits for greenhouse gases, if they increase those emissions by at least 75,000 tons per year.

Starting in July 2011, the rule would apply to any existing plant that emits at least 75,000 tons of greenhouse gases a year, or any new plant that emits 100,000 tons per year.

Emissions of 75,000 tons of carbon dioxide are equivalent to the annual emissions from 13,000 passenger vehicles, or the electricity use of about 8,200 homes per year, the EPA said.

The rule comes as Sens. John Kerry, D-Mass., and Joe Lieberman, I-Conn., made public a long-delayed bill aimed at curtailing greenhouse gas emissions. The bill would set a first-ever price on carbon dioxide emissions produced by coal-fired power plants and other large polluters.

The legislation aims to cut emissions of carbon dioxide and other heat-trapping greenhouse gases by 17 percent by 2020 and by more than 80 percent by 2050. Both targets are measured against 2005 levels and are the same as those set by a House bill approved last year.

The Obama administration has long said it would prefer that Congress pass a bill to cut greenhouse gas emissions but has used the threat of EPA regulation to push lawmakers in states heavily dependent on fossil fuels to support the climate bill.

Many large utilities and other energy companies have said they want Congress to act, believing they would be in a better bargaining position with Congress than in regulations issued by the EPA.

Even so, the energy bill faces a steep hill in the Senate. No Republican has signed on as a co-sponsor. Sen. Lindsey Graham, R-S.C., who had been working with Kerry and Lieberman, withdrew his support last week, saying it is impossible to pass the legislation in the current political climate.

The rule substantially raises the threshold amount of pollution required before greenhouse gas permits are needed. A proposal announced last September would have required permits for facilities that emit 25,000 tons per year.

Gina McCarthy, an assistant EPA administrator, said the change was made in response to complaints that the earlier proposal would have affected many small and medium-sized businesses, and even large apartment buildings. Such limits "clearly were not appropriate," she said.

Kenya Power on the spot over inflated electricity bills

Kenya Power token glitches, inflated bills disrupt prepaid meters via M-Pesa paybill 888880 and third-party vendors like Vendit and Dynamo, causing delays, fast-depleting tokens, and billing estimates; customers report weekend outages and business losses.

 

Key Points

Service failures delaying token generation and disputed charges from estimated meter readings and slow processing.

✅ Impacts M-Pesa paybill 888880 and authorized third-party vendors

✅ Causes delays, fast-depleting tokens, weekend business closures

✅ Linked to system downtime, billing estimates, meter reading gaps

 

Kenya Power is again on the spotlight following claims of inflated power bills and a glitch in its electronic payment system that made it impossible to top up tokens on prepaid meters.

Thousands of customers started experiencing the hitch in tokens generation on Friday evening, with the problem extending through the weekend.

Small businesses such as barber shops that top up multiple times a week were hardest hit.

“My business usually thrives during weekends but I was forced to close early in the evening due to lack of power although I had paid for the tokens that were never generated,” said Mr John Kamau, a fast food restaurant owner in Nairobi.

Kenya Power processes up to 200,000 electronic transactions per day for power users, with 85 per cent done through its Safaricom M-Pesa paybill number 888880.

The remaining share is handled by its authorised third party vendors such as Vendit (paybill number 501200) and Dynamo (800904), which charge a premium for the transaction.

The sole electricity distributor admitted its system encountered challenges that crippled token generation across all vendors, advising customers on prepaid meters to buy the units from Kenya Power banking halls across the country until normalcy returned.

 

STATEMENT

“The IT team is trying to figure out where the problem was before we issue a comprehensive statement on the issue,” the firm responded to Nation queries, adding that the issue had been resolved by yesterday afternoon.

Customers who use Vendit confirmed to Nation they had successfully bought tokens yesterday afternoon.

However, there have been complaints that third party vendors process tokens almost in real time, unlike Kenya Power which, despite indicating a 30 minute delay in its service promise, sometimes takes up to six hours.  

But other users complained of inflated power bills after being slapped with abnormally high charges.

 

TOKENS

The holder of account number 30624694, for instance, received a post-paid bill of Sh16,765 last month, up from Sh894 the previous month.

She indulged the company and ended up paying just over Sh1,000.

There have also been complaints of tokens getting depleted too fast. For instance, one customer who normally uses Sh4,000 per month complained of her credit running out in a week.

Kenya Power maintains it cannot read all post-paid meters across the country, compelling it to make estimates for a number of customers.

The company argues it is not cost-effective to have meter readers go to all homes. The firm recently indicated plans to put all domestic consumers on prepaid meters to reduce non-payment of electricity bills and cut operation costs on meter reading and postage.

 

POWER CONSUMPTION

The Nairobi Securities Exchange-listed firm has also adopted a new integrated customer management system to enable consumers to self-check their power consumption and understand their electricity bill and payment obligations through a phone app.

In the past, concerns have been rife that customers often encounter delays when buying tokens through paybill number 888880, unlike through other vendors.

This has raised questions on the ownership of the vendors and the cash commissions they are entitled to, with holiday scam warnings circulating in some markets as well.

 

FOUL PLAY

Kenya Power has, however, denied any foul play, saying the authorisation of other vendors was to ease pressure on its payment channel, which handles 85 per cent of the nearly 200,000 transactions per day.

“In fact we have 11 vendors, including Equitel, it’s just that people are only aware of Vendit and Dynamo because they have been aggressive in their marketing,” the company said.

Kenya Power has been battling court cases over inflated power bills after it emerged that the utility firm was backdating bills worth Sh10.1 billion from last November.

Toronto Prepares for a Surge in Electricity Demand as City Continues to Grow

Toronto Electricity Demand Growth underscores IESO projections of rising peak load by 2050, driven by population growth, electrification, new housing density, and tech economy, requiring grid modernization, transmission upgrades, demand response, and local renewable energy.

 

Key Points

It refers to the projected near-doubling of Toronto's peak load by 2050, driven by electrification and urban growth.

✅ IESO projects peak demand nearly doubling by 2050

✅ Drivers: population, densification, EVs, heat pumps

✅ Solutions: efficiency, transmission, storage, demand response

 

Toronto faces a significant challenge in meeting the growing electricity needs of its expanding population and ambitious development plans. According to a new report from Ontario's Independent Electricity System Operator (IESO), Toronto's peak electricity demand is expected to nearly double by 2050. This highlights the need for proactive steps to secure adequate electricity supply amidst the city's ongoing economic and population growth.


Key Factors Driving Demand

Several factors are contributing to the projected increase in electricity demand:

Population Growth: Toronto is one of the fastest-growing cities in North America, and this trend is expected to continue. More residents mean more need for housing, businesses, and other electricity-consuming infrastructure.

  • New Homes and Density: The city's housing strategy calls for 285,000 new homes within the next decade, including significant densification in existing neighbourhoods. High-rise buildings in urban centers are generally more energy-intensive than low-rise residential developments.
  • Economic Development: Toronto's robust economy, a hub for tech and innovation, attracts new businesses, including energy-intensive AI data centers that fuel further demand for electricity.
  • Electrification: The push to reduce carbon emissions is driving the electrification of transportation and home heating, further increasing pressure on Toronto's electricity grid.


Planning for the Future

Ontario and the City of Toronto recognize the urgency to secure stable and reliable electricity supplies to support continued growth and prosperity without sacrificing affordability, drawing lessons from British Columbia's clean energy shift to inform local approaches. Officials are collaborating to develop a long-term plan that focuses on:

  • Energy Efficiency: Efforts aim to reduce wasteful electricity usage through upgrades to existing buildings, promoting energy-efficient appliances, and implementing smart grid technologies. These will play a crucial role in curbing overall demand.
  • New Infrastructure: Significant investments in building new electricity generation, transmission lines, and substations, as well as regional macrogrids to enhance reliability, will be necessary to meet the projected demands of Toronto's future.
  • Demand Management: Programs incentivizing energy conservation during peak hours will help to avoid strain on the grid and reduce the need to build expensive power plants only used at peak demand times.


Challenges Ahead

The path ahead isn't without its hurdles.  Building new power infrastructure in a dense urban environment like Toronto can be time-consuming, expensive, and sometimes disruptive, especially as grids face harsh weather risks that complicate construction and operations. Residents and businesses might worry about potential rate increases required to fund these necessary investments.


Opportunity for Innovation

The IESO and the city view the situation as an opportunity to embrace innovative solutions. Exploring renewable energy sources within and near the city, developing local energy storage systems, and promoting distributed energy generation such as rooftop solar, where power is created near the point of use, are all vital strategies for meeting needs in a sustainable way.

Toronto's electricity future depends heavily on proactive planning and investment in modernizing its power infrastructure.  The decisions made now will determine whether the city can support economic growth, address climate goals and a net-zero grid by 2050 ambition, and ensure that lights stay on for all Torontonians as the city continues to expand.

Electricity deal clinches $100M bitcoin mining operation in Medicine Hat

Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.

 

Key Points

A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.

✅ 42 MW electricity from city; land lease near Unit 16

✅ Hut 8 expands to 60.7 MW; blockchain data centres

✅ 100 temporary jobs; 42 ongoing roles in Alberta

 

The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.

The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.

The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

#google#

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.

"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."

In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.

Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.

Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.

We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.

"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."

Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.

Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.

The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.

To Limit Climate Change, Scientists Try To Improve Solar And Wind Power

Wisconsin Solar and Wind Energy advances as rooftop solar, utility-scale farms, and NREL perovskite solar cells improve efficiency; wind turbines gain via wake modeling, yaw control, and grid-scale battery storage to cut carbon emissions.

 

Key Points

It is Wisconsin's growth in rooftop and utility-scale solar plus optimized wind turbines to cut carbon emissions.

✅ Perovskite solar cells promise higher efficiency, need longevity

✅ Wake modeling and yaw control optimize wind farm output

✅ Batteries and bids can offset reliance on natural gas

 

Solar energy in Wisconsin continued to grow in 2019, as more homeowners had rooftop panels installed and big utilities started building multi-panel solar farms.

Wind power is increasing more slowly in the state. However, renewable power developers are again coming forward with proposals for multiple turbines.

Nationally, researchers are working on ways to get even more energy from solar and wind, with the U.S. moving toward 30% electricity from wind and solar in coming years, as states like Wisconsin aim to reduce their carbon emissions over the next few decades.

One reason solar energy is growing in Wisconsin is due to the silicon panels becoming more efficient. But scientists haven't finished trying to improve panel efficiency. The National Renewable Energy Laboratory (NREL) in Golden, Col., is one of the research facilities experimenting with brushing a lab-made solution called perovskite onto a portion of a panel called a solar cell.

In a demonstration video supplied by NREL, senior scientist Maikel van Hest said that, in the lab anyway, the painted cell and its electrical connections called contacts, produce more energy:

"There you go! That's how you paint a perovskite solar cell. And you imagine that ultimately what you could do is you could see a company come in with a truck in front of your house and they would basically paint on the contacts first, dry those, and paint the perovskite over it. That you would have photovoltaic cells on the side of your house, put protective coating on it, and we're done."

Another NREL scientist, David Moore, says the new solar cells could be made faster and help meet what's expected to be a growing global demand for energy. However, Moore says the problem has been lack of stability.

"A solar cell with perovskites will last a couple years. We need to get that to 20-25 years, and that's the big forefront in perovskite research, is getting them to last longer," Moore told members of the Society of Environmental Journalists during a recent tour of NREL.

Another part of improving renewable energy is making wind turbines more productive. At NREL's Insight Center, a large screen showing energy model simulations dominates an otherwise darkened room. Visualization scientist Nicholas Brunhart-Lupo points to a display on the screen that shows how spinning turbines at one edge of a wind farm can cause an airflow called a wake, which curtails the power generation of other turbines.

"So what we find in these simulations is these four turbines back here, since they have this used air, this low-velocity wake being blown to their faces, they're only generating about 20% of the energy they should be generating," he explains.

Brunhart-Lupo says the simulations can help wind farm developers with placement of turbines as well as adjustments to the rotor and blades called the yaw system.

Continued progress with renewables may be vital to any state or national pledges to reduce use of fossil fuels and carbon emissions linked to climate change, including Biden's solar expansion plan as a potential pathway. Some scientists say to limit a rise in global temperature, there must be a big decline in emissions by 2050.

But even utilities that say they support use of more renewables, as why the grid isn't 100% renewable yet makes clear, aren't ready to let go of some energy sources. Jonathan Adelman of Xcel Energy, which serves part of Western Wisconsin, says Xcel is on track to close its last two coal-fired power plants in Minnesota. But he says the company will need more natural gas plants, even though they wouldn't run as often.

"It's not perfect. And it is in conflict with our ultimate goal of being carbon-free," says Adelman. "But if we want to facilitate the transition, we still need resources to help that happen."

Some in the solar industry would like utilities that say they need more natural gas plants to put out competitive bids to see what else might be possible. Solar advocates also note that in some states, energy regulators still favor the utilities.

Meanwhile, solar slowly marches ahead, including here in southeastern Wisconsin, as Germany's solar power boost underscores global momentum.

On the roof of a ranch-style home in River Hills, a work crew from the major solar firm Sunrun recently installed mounting brackets for solar panels.

Sunrun Public Policy Director Amy Heart says she supports research into more efficient renewables. But she says another innovation may have to come in the way regulators think.

"Instead of allowing and thinking about from the perspective of the utility builds the power plant, they replace one plant with another one, they invest in the infrastructure; is really thinking about how can these distributed solutions like rooftop solar, peer-to-peer energy sharing, and especially rooftop solar paired with batteries how can that actually reduce some of what the utility needs?

Large-scale energy storage batteries are already being used in some limited cases. But energy researchers continue to make improvements to them, too, with cheap solar batteries beginning to make widespread adoption more feasible as scientists race to reduce the expected additional harm of climate change.

U.S. Grid overseer issues warning on Coronavirus

NERC COVID-19 Grid Security Alert urges utilities to update business continuity plans, assess supply chain risk, and harden cybersecurity against spearphishing, social engineering, and remote-work vulnerabilities to protect the U.S. power grid and critical infrastructure.

 

Key Points

A notice urging U.S. utilities to fortify pandemic continuity, secure supply chains, and enhance cybersecurity.

✅ Mandates updates to business continuity and pandemic readiness plans

✅ Flags supply chain risks for PPE, electronics, chemicals, and logistics

✅ Warns of spearphishing, social engineering, VPN and remote-work threats

 

The top U.S. grid security monitor urged power utilities to prepare for the new coronavirus in a rare alert yesterday, adding to a chorus of warnings from federal and private organizations.

The North American Electric Reliability Corp. called for power providers to update business continuity plans in case of a pandemic outbreak and weigh the need to prioritize construction or maintenance projects, including updates on major projects like BC Hydro's Site C, while the COVID-19 virus continues to spread.

NERC is requiring electric utilities to answer questions on their readiness for a possible pandemic, including potential staffing strategies such as on-site sequestering, by March 20, an unusual step that underscores the severity of the threat to U.S. power systems.

The Electricity Information Sharing and Analysis Center, NERC's hub for getting the word out on dangers and vulnerabilities for the grid, also sent out an "all-points bulletin" on Feb. 5 addressing the coronavirus outbreak. That nonpublic document covered "potential supply chain issues stemming from a manufacturing slowdown in Asia," NERC spokeswoman Kimberly Mielcarek said.

Among offering basic hygiene and awareness recommendations, NERC's latest alert also encourages utilities to take stock of resources with supply chains affected by the virus. Because "China and nearby southeast Asian nations" have been impacted, NERC said, the supply chain hits will likely include "electronics, personal protective equipment and sanitation supplies, chemicals, and raw materials." The nonprofit grid overseer also warned of global transportation disruptions.

NERC also recommended utilities be on the lookout for cyberattacks taking advantage of the panic and using "coronavirus-themed opportunistic social engineering attacks" to hack into power companies' networks. Social engineering attacks are when hackers use social interactions to manipulate targets into giving up sensitive information.

"Spearphishing, watering hole, and other disinformation tactics are commonly used to exploit public interest in significant events," the alert said.

Electric utility representatives said they're working on or have already completed some of the steps outlined in NERC's alert, though nuclear plant workers have cited a lack of precautions in some cases.

"At this point, many of our members are activating and/or reviewing their business continuity and preparedness plans to ensure that operations and infrastructure are properly supported," said Tobias Sellier, director of media relations for the American Public Power Association, which represents around 1,400 electric utilities.

The power providers are also collaborating with other utilities such as "water, wastewater and gas," Sellier said.

Stephen Bell, senior director of media and public relations at the National Rural Electric Cooperative Association, said his group's members "have already taken a number of steps recommended by NERC" while continuing to maintain operations.

"Co-ops continue working with local, state and federal stakeholders to remain vigilant and prepared. These preparations include more frequent communications to key stakeholders, updating business continuity plans and monitoring new information from public health officials," said Bell.

Last week the Electricity Subsector Coordinating Council (ESCC), a panel of government and industry officials charged with responding to power-sector emergencies, scheduled a conference call discussing how to protect the grid from disruption if the virus infects system operators. Ohio-based utility American Electric Power Co. said it is limiting public visits, has created a high-level response team and is working to ensure operations can continue, while reinforcing downed power line safety, if the virus keeps spreading (Energywire, March 6).

Scott Aaronson, vice president for security and preparedness of the Edison Electric Institute, which represents major investor-owned utilities, said that the electric sector practices "contingency planning" to deal with unusual situations such as the coronavirus. That means that while the type of emergency may be new, dealing with an emergency situation is not, he said. Aaronson added that many of NERC's recommendations are based on what companies are already doing.

"We have heightened awareness given the circumstances, and we have messaging to employees all the way up and down the chain — from CEOs to frontline workers — that: given this time of heightened awareness and potential vulnerability, we have to practice hygiene both of the personal and cyber variety," said Aaronson.

Aaronson said that the ESCC had another call this week with the departments of Energy and Homeland Security and the Centers for Disease Control and Prevention to stay on top of the issue.

Hacking concerns
In a cybersecurity event yesterday, Lisa Monaco, co-chair of the Aspen Cybersecurity Group and former homeland security adviser during the Obama administration, warned that the coronavirus should be considered a national security threat.

"Frankly, [pandemic] is the thing that kept me up at night amongst many, many things that kept me up at night for four years in the White House," Monaco said.

Monaco went on to say the virus will strain organizations' IT infrastructure as more employees work remotely and households face higher electricity bills, and lead to "potentially more vulnerabilities for bad actors when it comes to cybersecurity."

On Friday, the DHS's Cybersecurity and Infrastructure Security Agency released advice on steps that can be taken to lessen the virus's impact on supply chains and cybersecurity, as well as tips for defending against scams exploiting coronavirus fears.

Cybersecurity firms also have been reporting a dramatic increase in spear-phishing attacks, with hackers reportedly using the coronavirus topic as a lure to trick victims into clicking a malicious link. Whether it's hackers aiming at industries susceptible to shipping disruptions, attacking countries like Italy hit particularly hard by the virus or even masquerading as the World Health Organization, cybercriminals are taking full advantage of the crisis, experts say.

Greg Young, vice president of cybersecurity at Trend Micro, said businesses should continue to expect an increase in targeted phishing attacks.

"With a large majority of businesses switching to a work-from-home model and less emphasis on in-person meetings, we also anticipate that malicious actors will start to impersonate digital tools such as 'free' remote conferencing services and other cloud computing software," said Young.

Working from home can be especially risky, as often home networks are less secure than corporate offices, Young said — meaning a hacker aiming to get into an enterprise network could find an "easier attack path" from a home office.

The Department of Energy is asking employees to make sure they can work remotely when needed, even as some agencies set limits with EPA telework policy, including updating security questions and asking those with government-furnished laptops to be sure they have a VPN, or virtual private network, account. In a post added this week to the agency's website, Chief Information Officer Rocky Campione said the department over the next two weeks will be initiating steps to ensure there is adequate network capacity to carry out DOE's work.

"Ensuring the continued operations of the department's many varied missions requires diligence," Campione said.

Idaho Power Settlement Could Close Coal Plant, Raise Rates

Idaho Power Valmy Settlement outlines early closure of the North Valmy coal-fired plant in Nevada, accelerated depreciation recovery, a 1.17% base-rate increase, and impacts for customers, NV Energy co-ownership, and Idaho Public Utilities Commission review.

 

Key Points

A proposed agreement to close North Valmy early, recover costs via a 1.17% rate hike, and seek PUC approval.

✅ Unit 1 closes 2019; Unit 2 closes 2025 in Nevada.

✅ 1.17% base-rate hike; about $1.20 per 1,000 kWh monthly bill.

✅ Idaho PUC comment deadline May 25; NV Energy co-owner.

 

State regulators have set a May 25 deadline for public comment on a proposed settlement related to the early closure of a coal-fired plant co-owned by Idaho Power, even as some utilities plan to keep a U.S. coal plant running indefinitely in other jurisdictions.

The settlement calls for shuttering Unit 1 of the North Valmy Power Plant in Nevada in 2019, with Unit 2 closing in 2025, amid regional coal unit retirements debates. The units had been slated for closure in 2031 and 2035, respectively.

If approved by the Idaho Public Utilities Commission, the settlement would increase base rates by approximately $13.3 million, or 1.17 percent, in order to allow the company to recover its investment in the plant on an accelerated basis.

That equates to an additional $1.20 on the monthly bill of the typical residential customer using 1,000 kilowatt-hours of energy per month.

Idaho Power, which co-owns the plant with NV Energy, maintains that closing Valmy early rather than continuing to operate it until it is fully depreciated in 2035, will ultimately save customers $103 million in today's dollars.

The company said a significant decrease in market prices for electricity has made it uneconomic to operate the plant except during extremely cold or hot weather, when the demand for energy peaks, a trend underscored by transactions involving the San Juan Generating Station deal elsewhere. The company also said plant balances have increased by approximately $70 million since its last general rate case in 2011, due to routine maintenance and repairs, as well as investments required to meet environmental regulations.

The proposed settlement reflects a number of changes to Idaho Power's original proposal regarding Valmy, and comes in the wake of discussions with interested parties in February and April, against the backdrop of a broader energy debate over plant closures and reliability.

In its initial application, filed in October, Idaho Power proposed closing both units in 2025. The original proposal would have increased base rates by $28.5 million, or about 2.5 percent, in order to allow the company to recover its costs associated with the plant's accelerated depreciation, decommissioning and anticipated investments, with cautionary examples such as the Kemper power plant costs illustrating potential risks.

Concurrently, Idaho Power asked for commission approval to adjust depreciation rates for its other plants and equipment based on the result of a study it conducts every five years, as outlined in Case IPC-E-16-23. The adjustment would have led to a $6.7 million increase to base rates.

The two requests filed in October would have increased customer costs by a total of $35.2 million or 3.1 percent, leading to a $3.08 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.

The proposed settlement submitted to the Commission on May 4 calls for $13,285,285 to be recovered from all customer classes through base rates until 2028, all related to the Valmy shutdown. That is an increase of 1.17 percent and would result in a $1.20 increase on the bills of the typical residential customer who uses 1,000 kilowatt-hours per month.
