Construction is about to begin in southwestern Fresno County on three large arrays of solar power panels to produce electricity for Pacific Gas & Electric Co.

The three projects will be built near the towns of Five Points and Helm. They will be completed by October and generate a combined 50 megawatts of electricity — enough to meet the needs of about 15,000 homes, according to PG&E.

The sites represent the first big push in PG&E's efforts to develop solar projects that it will own and operate. PG&E expects to build 250 MW of power-producing capacity over the next five years.

The utility has hired Cupertino Electric Inc. to build two of the plants: a 20 MW plant on a 130-acre site just west of Helm, and a 15 MW project on 160 acres south of Five Points.

The third plant, a 15 MW project on 160 acres southwest of Five Points, will be built by SOLON Corp. for PG&E.

Each site will have thousands of crystalline silicon photovoltaic panels that convert sunlight directly into electricity. PG&E already owns the vacant land for the plants.

"The Central Valley holds tremendous potential as a source of clean energy for California," said Mike Jones, a power-generation manager for PG&E. "Our solar projects in the region are a win for the local economy and for the state's environment."

PG&E spokesman Blair Jones said the Fresno County projects should create about 500,000 hours of paid work. Jones said the contractors will do their own hiring, but "it's our goal that they use local residents to build these facilities where possible."

Autumn Casadonte, a spokeswoman for San Jose-based Cupertino Electric, said her company expects to employ more than 200 people over the course of its work on the two sites. Most of those will be hired from within Fresno County, where the unemployment rate of about 17 is well above the state and national average.

A representative for SOLON, an Arizona-based subsidiary of Germany's SOLON SE, said the company will also use local labor to build its project.

The three PG&E arrays will rank among the biggest solar photovoltaic plants built in the Valley when they begin producing electricity this fall. They will rival 20 MW and 19 MW plants under construction by Eurus Energy America near Avenal, in western Kings County.

Cupertino Electric recently completed a 6.7 MW plant in Porterville for Southern California Edison, but the two plants it will build in Fresno County are a step up for the company. "The projects are progressively getting bigger and bigger," Casadonte said.

The state's major utilities, including PG&E and Southern California Edison, are under pressure to increase their proportion of electricity from solar and other renewable or "green" sources to 33 by 2020. In 2009, the most recent available information from the California Public Utilities Commission, renewable energy accounted for about 15 of PG&E's retail sales and about 17 of Edison's sales.

It's not going to come cheap, however. PG&E's cost to build its solar projects is confidential, but they will be passed along to the utility's customers.

Blair Jones said the average residential customer can expect to pay about 58 cents more on his or her bill per month by 2015 to cover the cost of developing the 250 MW of solar capacity that PG&E will own and operate.

"Solar tends to be more expensive than some other sources of energy, but provides many benefits," Jones said. And growing demand for solar from PG&E and other utilities "is also helping to drive innovations and economies of scale that are helping bring down solar costs at a rapid rate."

PG&E also continues to increase its purchases of electricity from independent power providers with a goal of an additional 250 MW of solar power within the next five years. The utility has a handful of power-purchase agreements in place for solar power projects — both operating and on the drawing board — in Fresno County.

Cancelling Ontario's wind project could cost over $100M, company warns

White Pines Project cancellation highlights Ontario's wind farm contract dispute in Prince Edward County, involving IESO approvals, Progressive Conservatives' legislation, potential court action, and costs to ratepayers amid green energy policy shifts.

 

Key Points

The termination effort for Ontario's White Pines wind farm contract, triggering legal, legislative, and cost disputes.

✅ Contract with IESO dates to 2009; final approval during election

✅ PCs seek legislation insulating taxpayers from litigation

✅ Cancellation could exceed $100M; cost impact on ratepayers

 

Cancelling an eastern Ontario green energy project that has been under development for nearly a decade could cost more than $100 million, the president of the company said Wednesday, warning that the dispute could be headed to the courts.

Ontario's governing Progressive Conservatives said this week that one of their first priorities during the legislature's summer sitting would be to cancel the contract for the White Pines Project in Prince Edward County.

Ian MacRae, president of WPD Canada, the company behind the project, said he was stunned by the news given that the project is weeks away from completion.

"What our lawyers are telling us is we have a completely valid contract that we've had since 2009 with the (Independent Electricity System Operator). ... There's no good reason for the government to breach that contract," he said.

The government has also not reached out to discuss the cancellation, he said. Meanwhile, construction on the site is in full swing, he said.

"Over the last couple weeks we've had an average of 100 people on site every day," he said. "The footprint of the project is 100 per cent in. So, all the access roads, the concrete for the base foundations, much of the electrical infrastructure. The sub-station is nearing completion."

The project includes nine wind turbines meant to produce enough electricity to power just over 3,000 homes annually, even as Ontario looks to build on an electricity deal with Quebec for additional supply. All of the turbines are expected to be installed over the next three weeks, with testing scheduled for the following month.

MacRae couldn't say for certain who would have to pay for the cancellation, electricity ratepayers or taxpayers.

"Somehow that money would come from IESO and it would be my assumption that would end up somehow on the ratepayers, despite legislation to lower electricity rates now in place," he said. "We just need to see what the government has in mind and who will foot the bill."

Progressive Conservative house leader Todd Smith, who represents the riding where the project is being built, said the legislation to cancel the project will also insulate taxpayers from domestic litigation over the dismantling of green energy projects.

"This is something that the people of Prince Edward County have been fighting ... for seven years," he said. "This shouldn't have come as a surprise to anybody that this was at the top of the agenda for the incoming government, which has also eyed energy independence in recent decisions."

Smith questioned why Ontario's Independent Electricity System Operator gave the final approval for the project during the spring election campaign.

"There's a lot of questions about how this ever got greenlighted in the first place," he said. "This project was granted its notice to proceed two days into the election campaign ... when (the IESO) should have been in the caretaker mode."

Terry Young, the IESO's vice president of policy, engagement and innovation, said the agency could not comment because of the pending introduction of legislation to cancel the deal, following a recent auditor-regulator dispute that drew attention to oversight.

NDP Leader Andrea Horwath said the new Tory government is behaving like the previous Liberal government by cancelling energy projects and tearing up contracts amid ongoing debates over Ontario's hydro mess and affordability. She likened the Tory plan to the Liberal gas plant scandal that saw the government relocate two plants at a substantial cost to taxpayers.

Power bill cut for 22m Thailand houses

Thailand Covid-19 Electricity Bill Relief offers energy subsidies, tariff cuts, and free power for small meters, helping work-from-home users as authorities waive charges and discount kWh rates via EGAT, MEA, PEA for three months.

 

Key Points

Program waiving or cutting household electricity bills for 22 million homes in March-May, easing work-from-home costs.

? Free power for meters <= 5 amps; up to 10M homes

? Up to 800 kWh: pay February rate; above, 50% discount

? >3,000 kWh: 30% discount; program valid March-May

 

The Thailand cabinet has formally approved energy authorities' decision to either waive or cut electricity charges, similar to B.C. electricity relief measures, for 22 million households where people are working at home because of the coronavirus disease.

Energy Minister Sontirat Sontijirawong said after the cabinet meeting on Tuesday that the ministers acknowledged the step taken by from the Energy Regulatory Commission, the Electricity Generating Authority of Thailand, the Metropolitan Electricity Authority and the Provincial Electricity Authority and noted parallels with Ontario's COVID-19 hydro plan rolled out to support ratepayers.

The measure would be valid for three months, from March to May, and cover 22 million households. It would cost the state 23.68 billion baht in lost revenue, he said, a pattern also seen with Ontario rate reductions affecting provincial revenues.


"The measure reduces the electricity charges burden on households. It is the cost of living of the people who are working from home to support the government's control of Covid-19," Mr Sontirat said.

The business sector also wants similar assistance, echoing sentiments from Ontario manufacturers during recent price reduction efforts. He said their requests were being considered.

Free electricity is extended to households with a power meter of no more than 5 amps. Up to 10 million households are expected to benefit, although issues like electricity payment challenges in India highlight different market contexts.

For households with a power meter over 5 amps, if their consumption does not exceed 800 units (kilowat hours), they will pay as much as they did in their February bill. The amount over 800 units will be subject to a 50 per cent discount, while elsewhere B.C. commercial consumption has fallen sharply.

Large houses that consume more than 3,000 units will get a 30 per cent discount, at a time when BC Hydro demand is down 10%.

Niagara Falls Powerhouse Gets a Billion-Dollar Upgrade for the 21st Century

Sir Adam Beck I refurbishment boosts hydropower capacity in Niagara, upgrading turbines, generators, and controls for Ontario Power Generation. The billion-dollar project enhances grid reliability, clean energy output, and preserves heritage architecture.

 

Key Points

An OPG upgrade of the historic Niagara plant to replace equipment, add 150 MW, and extend clean power life.

✅ Adds at least 150 MW to Ontario's clean energy supply

✅ Replaces turbines, generators, transformers, and controls

✅ Creates hundreds of skilled construction and engineering jobs

 

Ontario's iconic Sir Adam Beck hydroelectric generating station in Niagara is set to undergo a massive, billion-dollar refurbishment. The project will significantly boost the power station's capacity and extend its lifespan, with efforts similar to revitalizing older dams seen across North America, ensuring a reliable supply of clean energy for decades to come.


A Century of Power Generation

The Sir Adam Beck generating stations have played a pivotal role in Ontario's power grid for over a century. The first generating station, Sir Adam Beck I, went online in 1922, followed by Sir Adam Beck II in 1954. A third station, the Sir Adam Beck Pump Generating Station, was added in 1957, highlighting the role of pumped storage in Ontario for grid flexibility, Collectively, they form one of the largest hydroelectric complexes in the world, harnessing the power of the Niagara River.


Preparing for Increased Demand

The planned refurbishment of Sir Adam Beck I is part of Ontario Power Generation's broader strategy, which includes the life extension at Pickering NGS among other initiatives, to meet the growing energy demands of the province. With the population expanding and a shift towards electrification, Ontario will need to increase its power generation capacity while also focusing on sustainable and clean sources of energy.


Billions to Secure Sustainable Energy

The project to upgrade Sir Adam Beck I carries a hefty price tag of over a billion dollars but is considered a vital investment in Ontario's energy infrastructure, and recent OPG financial results underscore the utility's capacity to manage long-term capital plans. The refurbishment will see the replacement of aging turbines, generators, and transformers, and a significant upgrade to the station's control systems. Following the refurbishment, the output of Sir Adam Beck I is expected to increase by at least 150 megawatts – enough to power thousands of homes and businesses.


Creating Green Jobs

In addition to securing the province's energy future, the upgrade presents significant economic benefits to the Niagara region. The project will create hundreds of well-paying construction and engineering jobs, similar to employment from the continued operation of Pickering Station across Ontario, during the several years it will take to implement the upgrades.


Commitment to Hydropower

Ontario Power Generation (OPG) has long touted the benefits of hydropower as a reliable, renewable, and affordable source of energy, even as an analysis of rising grid emissions underscores the importance of clean generation to meet demand. The Sir Adam Beck complex is a shining example and represents a significant asset in the fight against climate change while providing reliable power to Ontario's businesses and residents.


Balancing Energy Needs with Heritage Preservation

The refurbishment will also carefully integrate modern design with the station's heritage elements, paralleling decisions such as the refurbishment of Pickering B that weigh system needs and public trust. Sir Adam Beck I is a designated historic site, and the project aims to preserve the station's architectural significance while enhancing its energy generation capabilities.

Western Canada drought impacting hydropower production as reservoirs run low

Western Canada Hydropower Drought strains British Columbia and Manitoba as reservoirs hit historic lows, cutting hydroelectric output and prompting power imports, natural gas peaking, and grid resilience planning amid climate change risks this winter.

 

Key Points

Climate-driven reservoir lows cut hydro in B.C. and Manitoba, prompting imports and backup gas to maintain reliability.

✅ Reservoirs at multi-year lows cut hydro generation capacity

✅ BC Hydro and Manitoba Hydro import electricity for reliability

✅ Natural gas turbines used; climate change elevates drought risk

 

Severe drought conditions in Western Canada are compelling two hydroelectricity-dependent provinces, British Columbia and Manitoba, to import power from other regions. These provinces, known for their reliance on hydroelectric power, are facing reduced electricity production due to low water levels in reservoirs this autumn and winter as energy-intensive customers encounter temporary connection limits.

While there is no immediate threat of power outages in either province, experts indicate that climate change is leading to more frequent and severe droughts. This trend places increasing pressure on hydroelectric power producers in the future, spurring interest in upgrading existing dams as part of adaptation strategies.

In British Columbia, several regions are experiencing "extreme" drought conditions as classified by the federal government. BC Hydro spokesperson Kyle Donaldson referred to these conditions as "historic," and a first call for power highlights the strain, noting that the corporation's large reservoirs in the north and southeast are at their lowest levels in many years.

To mitigate this, BC Hydro has been conserving water by utilizing less affected reservoirs and importing additional power from Alberta and various western U.S. states. Donaldson confirmed that these measures would persist in the upcoming months.

Manitoba is also facing challenges with below-normal levels in reservoirs and rivers. Since October, Manitoba Hydro has occasionally relied on its natural gas turbines to supplement hydroelectric production as electrical demand could double over the next two decades, a measure usually reserved for peak winter demand.

Bruce Owen, a spokesperson for Manitoba Hydro, reassured that there is no imminent risk of a power shortage. The corporation can import electricity from other regions, similar to how it exports clean energy in high-water years.

However, the cost implications are significant. Manitoba Hydro anticipates a financial loss for the current fiscal year, with more red ink tied to emerging generation needs, the second in a decade, with the previous one in 2021. That year, drought conditions led to a significant reduction in the company's power production capabilities, resulting in a $248-million loss.

The 2021 drought also affected hydropower production in the United States. The U.S. Department of Energy reported a 16% reduction in overall generation, with notable decreases at major facilities like Nevada's Hoover Dam, where production dropped by 25%.

Drought has long been a major concern for hydroelectricity producers, and they plan their operations with this risk in mind. Manitoba's record drought in 1940-41, for example, is a benchmark for Manitoba Hydro's operational planning to ensure sufficient electricity supply even in extreme low-water conditions.

Climate change, however, is increasing the frequency of such rare events, highlighting the need for more robust backup systems such as new turbine investments to enhance reliability. Blake Shaffer, an associate professor of economics at the University of Calgary specializing in electricity markets, emphasized the importance of hydroelectric systems incorporating the worsening drought forecasts due to climate change into their energy production planning.

Nuclear plants produce over half of Illinois electricity, almost faced retirement

Illinois Zero Emission Credits support nuclear plants via tradable credits tied to wholesale electricity prices, carbon costs, created by the Future Energy Jobs Bill to avert Exelon closures and sustain low-carbon power.

 

Key Points

State credits that value nuclear power's zero-carbon output, priced by market and carbon metrics to keep plants running.

✅ Pegged to wholesale prices, carbon costs, and state averages.

✅ Created by Future Energy Jobs Bill to prevent plant retirements.

✅ Supports Exelon Quad Cities and Clinton nuclear facilities.

 

Nuclear plants have produced over half of Illinois electricity generation since 2010, but the states two largest plants would have been retired amid the debate over saving nuclear plants if the state had not created a zero emission credit (ZEC) mechanism to support the facilities.

The two plants, Quad Cities and Clinton, collectively delivered more than 12 percent of the states electricity generation over the past several years. In May 2016, however, Exelon, the owner of the plants, announced that they had together lost over $800 million dollars over the previous six years and revealed plans to retire them in 2017 and 2018, similar to the Three Mile Island closure later announced for 2019 by its owner.

In December 2016, Illinois passed the Future Energy Jobs Bill, which established a zero emission credit (ZEC) mechanism

to support the plants financially. Exelon then cancelled its plans to retire the two facilities.

The ZEC is a tradable credit that represents the environmental attributes of one megawatt-hour of energy produced from the states nuclear plants. Its price is based on a number of factors that include wholesale electricity market prices, nuclear generation costs, state average market prices, and estimated costs of the long-term effects of carbon dioxide emissions.

The bill is set to take effect in June, but faces multiple court challenges as some utilities have expressed concerns that the ZEC violates the commerce clause and affects federal authority to regulate wholesale energy prices, amid gas-fired competition in nearby markets that shapes the revenue outlook.

Illinois ranks first in the United States for both generating capacity and net electricity generation from nuclear power, a resource many see as essential for net-zero emissions goals, and accounts for approximately one-eighth of the nuclear power generation in the nation.

During this Pandemic, Save Money - How To Better Understand Your Electricity Bill

Commercial Electric Tariffs explain utility rate structures, peak demand charges, kWh vs kW pricing, time-of-use periods, voltage, delivery, capacity ratchets, and riders, guiding facility managers in tariff analysis for accurate energy savings.

 

Key Points

Commercial electric tariffs define utility pricing for energy, demand, delivery, time-of-use periods, riders, and ratchet charges.

✅ Separate kWh charges from kW peak demand fees.

✅ Verify time-of-use windows and demand interval length.

✅ Review riders, capacity ratchets, and minimum demand clauses.

 

Especially during these tough economic times, as major changes to electric bills are debated in some states, facility executives who don’t understand how their power is priced have been disappointed when their energy projects failed to produce expected dollar savings. Here’s how not to be one of them.

Your electric rate is spelled out in a document called a “tariff” that can be downloaded from your utility’s web page. A tariff should clearly spell out the costs for each component that is part of your rate, reflecting cost allocation practices in your region. Don’t be surprised to learn that it contains a bunch of them. Unlike residential electric rates, commercial electric bills are not based solely on the quantity of kilowatt-hours (kWh) consumed in a billing period (in the United States, that’s a month). Instead, different rates may apply to how your power is supplied, how it is delivered via electricity delivery charges, when it was consumed, its voltage, how fast it was used (in kW), and other factors.

If a tariff’s lingo and word structure are too opaque, spend some time with a utility account rep to translate it. Many state utility commissions also have customer advocates that may assist as they explore new utility rate designs that affect customers. Alternatively, for a fee, facility managers can privately chat with an energy consultant.

Common mistakes

Many facility managers try to estimate savings based on an averaged electric rate, i.e., annual electric spend divided by annual kWh. However, in markets where electricity demand is flat, such a number may obscure the fastest rising cost component: monthly peak demand charges, measured in dollars per kW (or kilo-volt-amperes, kVA).

This charge is like a monthly speeding ticket, based solely on the highest speed you drove during that time. In some areas, peak demand charges now account for 30 to 60 percent of a facility’s annual electric spend. When projecting energy cost savings, failing to separately account for kW peak demand and kWh consumption may result in erroneous results, and a lot of questions from the C-suite.

How peak demand charges are calculated varies among utilities. Some base it on the highest average speed of use across one hour in a month, while others may use the highest average speed during a 15- or 30-minute period. Others may average several of the highest speeds within a defined time period (for example, 8 a.m. to 6 p.m. on weekdays). It is whatever your tariff says it is.

Because some power-consuming (or producing) devices, including those tied to smart home electricity networks, vary in their operation or abilities, they may save money on a few — but not all — of those rate components. If an equipment vendor calculates savings from its product by using an average electric rate, take pause. Tell the vendor to return after the proposal has been redone using tariff-based numbers.

When a vendor is the only person calculating potential savings from using a product, there’s also a built-in conflict of interest: The person profiting from an equipment sale should not also be the one calculating its expected financial return. Before signing any energy project contracts, it’s essential that someone independent of the deal reviews projected savings. That person (typically an energy or engineering consultant) should be quite familiar with your facility’s electric tariff, including any special provisions, riders, discounts, etc., that may pertain. When this doesn’t happen, savings often don’t occur as planned. 

For example, some utilities add another form of demand charge, based on the highest kW in a year. It has various names: capacity, contract demand, or the generic term “ratchet charge.” Some utilities also have a minimum ratchet charge which may be based on a percent of a facility’s annual kW peak. It ensures collection of sufficient utility revenue to cover the cost of installed transmission and distribution even when a customer significantly cuts its peak demand.
