Westerville has become the first of 92 member-communities to reject the prospect of long-term ownership in a coal-fueled power plant proposed for Meigs County along the Ohio River.

Led by Westerville City Councilman Craig Treneff, council members shared numerous concerns about the project before voting it down 5-1. Treneff cited growing resistance to coal as an energy source, stating, "I don't want Westerville to be on the wrong side of environmental choices 20 to 30 years from now."

The proposal from American Municipal Power of Ohio would have locked the city into a 50-year contract with the utility to fund a new power plant, in return for rights on the power it produces. The plant, expected to begin operating in 2013, would have provided about 40 percent of Westerville's nonpeak electricity.

But the deal would have required the city to make monthly payments, regardless of how much, if any, energy the plant produced.

"I think it's a very wise decision. It's an extremely risky plant that could cause a lot of public health and environmental damage," said Sandy Buchanan, executive director of Ohio Citizen Action, after the vote.

AMPOhio President Marc S. Gerken quickly left the meeting and didn't respond to requests for a comment. Kent Carson, spokesman for AMPOhio, said Westerville's vote shouldn't influence other member communities who have yet to vote before a Nov. 1 deadline.

"They (Westerville) didn't say it was a bad project," Carson said. "They said it was not good for Westerville."

Treneff called the risk "impossible to quantify. I can't take a 50-year risk, not being able to predict that far ahead."

Councilwoman Kathy Cocuzzi also pointed out that, within 50 years, other energy sources might be an option. She suggested that the city might offer incentives to residents who use solar or geothermal heat sources.

"The only thing I'm committed to for 50 years is my marriage," she said.

The only proponent was Councilman Bill Highfield, who said that council should have supported the decision of the city-hired energy consultant to accept the deal.

"We have a responsibility to the people of Westerville to provide them with as stable of a financial future as is possible. If we can save them over a million dollars a year, I think that's pretty decent."

The average yearly rate savings has been about $70 per resident, he said.

Councilwoman Anne Gonzales said she doubted that AMPOhio would have been able to construct the plant in a timely manner. Since 2004, and the end of a long-term contract with American Electric Power, Westerville's power costs have risen sharply. This has prompted suggestions that the city get out of supplying power all together.

But Council Chairman Damon "Chip" Wetterauer praised the city's electric division, citing several infrastructure projects it has helped to fund.

"Make no mistake about it," he said, "the electric division is not for sale."

California faces huge power cuts as wildfires rage

California Wildfire Power Shut-Offs escalate as PG&E imposes blackouts amid high winds, Getty and Kincade fires, mass evacuations, Sonoma County threats, and a state of emergency, drawing regulatory scrutiny over grid safety and outage scope.

 

Key Points

Planned utility outages to curb wildfire risk during extreme winds, prompting evacuations and regulatory scrutiny.

✅ PG&E preemptive blackouts under regulator inquiry

✅ Getty and Kincade fires drive mass evacuations

✅ Sonoma County under threat amid high winds

 

Pacific Gas & Electric (PG&E) already faces an investigation by regulators after cutting supplies to 970,000 homes and businesses amid California blackouts that raised concerns.

It announced that another 650,000 properties would face precautionary shut-offs.

Wildfires fanned by the strong winds are raging in two parts of the state.

Thousands of residents near the wealthy Brentwood neighbourhood of Los Angeles have been told to evacuate because of a wildfire that began early on Monday.

Further north in Sonoma County, a larger fire has forced 180,000 people from their homes.

California's governor has declared a state-wide emergency.

 

What about the power cuts?

On Monday regulators announced a formal inquiry into whether energy utilities broke rules by pre-emptively cutting power to an estimated 2.5 million people, amid a blackouts policy debate that intensified, as wildfire risks soared.

They did not name any utilities but analysts said PG&E was responsible for the bulk of the "public safety power shut-offs", and later faced a Camp Fire guilty plea that underscored its liabilities.

The company filed for bankruptcy in January after facing hundreds of lawsuits from victims of wildfires in 2017 and 2018.

Of the 970,000 properties hit by the most recent cuts, under half had their services back by Monday, and some sought help through wildfire assistance programs, the Associated Press reported.

Despite criticism that the precautionary blackouts were too widespread and too disruptive, PG&E said more would come on Tuesday and Wednesday because further strong winds were expected.

The company said it had logged more than 20 preliminary reports of damage to its network from the most recent windstorm.

In a video posted to Twitter on Saturday, Governor Gavin Newsom said the power cuts were "infuriating everyone, and rightfully so".

 

Where are the fires now?

In Los Angeles, the Getty Fire has burned over 600 acres (242 ha) and about 10,000 buildings are in the mandatory evacuation zone.

At least eight homes have been destroyed and five others damaged.

"If you are in an evacuation zone, don't screw around," Mr Schwarzenegger tweeted. "Get out."

LA fire chief Ralph Terrazas said fire crews had been "overwhelmed" by the scale of the fires.

"They had to make some tough decisions on which houses they were able to protect," he said.

"Many times it depends on where the ember lands. I saw homes that were adjacent to homes that were totally destroyed, without any damage."

In northern California, schools remain closed in Sonoma County, where tens of thousands of homes and businesses are under threat.

Sonoma has been ravaged by the Kincade Fire, which started on Wednesday and has burned through 50,000 acres of land, fanned by the winds.

The Kincade Fire began seven minutes after a nearby power line was damaged, and power lines may have started fires according to reports, but PG&E has not yet confirmed if the power glitch started the blaze.

About 180,000 people have been ordered to evacuate, with roads around Santa Rosa north of San Francisco packed with cars as people tried to flee.

There are fears the flames could cross the 101 highway and enter areas that have not seen wildfires since the 1940s.

If B.C. wants to electrify all road vehicles by 2055, it will need to at least double its power output: study

B.C. EV Electrification 2055 projects grid capacity needs doubling to 37 GW, driven by electric vehicles, renewable energy expansion, wind and solar generation, limited natural gas, and policy mandates for zero-emission transportation.

 

Key Points

A projection that electrifying all B.C. road transport by 2055 would more than double grid demand to 37 GW.

✅ Site C adds 1.1 GW; rest from wind, solar, limited natural gas.

✅ Electricity price per kWh rises 9%, but fuel savings offset.

✅ Significant GHG cuts with 93% renewable grid under Clean Energy Act.

 

Researchers at the University of Victoria say that if B.C. were to shift to electric power for all road vehicles by 2055, the province would require more than double the electricity now being generated.

The findings are included in a study to be published in the November issue of the Applied Energy journal.

According to co-author and UVic professor Curran Crawford, the team at the university's Pacific Institute for Climate Solutions took B.C.'s 2015 electrical capacity of 15.6 gigawatts as a baseline, and added projected demands from population and economic growth, then added the increase that shifting to electric vehicles would require, while acknowledging power supply challenges that could arise.

They calculated the demand in 2055 would amount to 37 gigawatts, more than double 15.6 gigawatts used in 2015 as a baseline, and utilities warn of a potential EV charging bottleneck if demand ramps up faster than infrastructure.

"We wanted to understand what the electricity requirements are if you want to do that," he said. "It's possible — it would take some policy direction."

B.C. announces $4M in rebates for home and work EV charging stations across the province
The team took the planned Site C dam project into account, but that would only add 1.1 gigawatts of power. So assuming no other hydroelectric dams are planned, the remainder would likely have to come from wind and solar projects and some natural gas.

"Geothermal and biomass were also in the model," said Crawford, adding that they are more expensive electricity sources. "The model we were using, essentially, we're looking for the cheapest options."

The electricity bill, per kilowatt hour, would increase by nine per cent, according to the team's research, but Crawford said getting rid of the gasoline and diesel now used to fuel vehicles could amount to an overall cost saving, especially when combined with zero-emission vehicle incentives available to consumers.

The province introduced a law this year requiring that all new light-duty vehicles sold in B.C. be zero emission by 2040, while the federal 2035 EV mandate adds another policy signal, so the researchers figured 2055 was a reasonable date to imagine all vehicles on the road to be electric.

Crawford said hydrogen-powered vehicles weren't considered in the study, as the model used was already complicated enough, but hydrogen fuel would actually require more electricity for the electrolysis, when compared to energy stored in batteries.

Electric vehicles are approaching a tipping point as faster charging becomes more available — here's why
The study also found that shifting to all-electric ground transportation in B.C. would also mean a significant decrease in greenhouse gas emissions, assuming the Clean Energy Act remains in place, which mandates that 93 per cent of grid electricity must come from renewable resources, whereas nationally, about 18 per cent of electricity still comes from fossil fuels, according to 2019 data. 

"Doing the electrification makes some sense — If you're thinking of spending some money to reduce carbon emissions, this is a pretty cost effective way of doing that," said Crawford.

California electricity pricing changes pose an existential threat to residential rooftop solar

California Rooftop Solar Rate Reforms propose shifting net metering to fixed access fees, peak-demand charges, and time-of-use pricing, aligning grid costs, distributed generation incentives, and retail rates for efficient, least-cost electricity and fair cost recovery.

 

Key Points

Policies replacing net metering with fixed fees, demand charges, and time-of-use rates to align costs and incentives.

✅ Large fixed access charge funds grid infrastructure

✅ Peak-demand pricing reflects capacity costs at system peak

✅ Time-varying rates align marginal costs and emissions

 

The California Public Service Commission has proposed revamping electricity rates for residential customers who produce electricity through their rooftop solar panels. In a recent New York Times op‐​ed, former Governor Arnold Schwarzenegger argued the changes pose an existential threat to residential rooftop solar. Interest groups favoring rooftop solar portray the current pricing system, often called net metering, in populist terms: “Net metering is the one opportunity for the little guy to get relief, and they want to put the kibosh on it.” And conventional news coverage suggests that because rooftop solar is an obvious good development and nefarious interests, incumbent utilities and their unionized employees, support the reform, well‐​meaning people should oppose it. A more thoughtful analysis would inquire about the characteristics and prices of a system that supplies electricity at least cost.

Currently, under net metering customers are billed for their net electricity use plus a minimum fixed charge each month. When their consumption exceeds their home production, they are billed for their net use from the electricity distribution system (the grid) at retail rates. When their production exceeds their consumption and the excess is supplied to the grid, residential consumers also are reimbursed at retail rates. During a billing period, if a consumer’s production equaled their consumption their electric bill would only be the monthly fixed charge.

Net metering would be fine if all the fixed costs of the electric distribution and transmission systems were included in the fixed monthly charge, but they are not. Between 66 and 77 percent of the expenses of California private utilities do not change when a customer increases or decreases consumption, but those expenses are recovered largely through charges per kWh of use rather than a large monthly fixed charge. Said differently, for every kWh that a PG&E solar household exported into the grid in 2019, it saved more than 26 cents, on average, while the utility’s costs only declined by about 8 cents or less including an estimate of the pollution costs of the system’s fossil fuel generators. The 18‐​cent difference pays for costs that don’t change with variation in a household’s consumptions, like much of the transmission and distribution system, energy efficiency programs, subsidies for low‐​income customers, and other fixed costs. Rooftop solar is so popular in California because its installation under a net metering system avoids the 18 cents, creating a solar cost shift onto non-solar customers. Rooftop solar is not the answer to all our environmental needs. It is simply a form of arbitrage around paying for the grid’s fixed costs.

What should electricity tariffs look like? This article in Regulation argues that efficient charges for electricity would consist of three components: a large fixed charge for the distribution and transmission lines, meter reading, vegetation trimming, etc.; a peak‐​demand charge related to your demand when the system’s peak demand occurs to pay for fixed capacity costs associated with peak use; and a charge for electricity use that reflects the time‐ and location‐​varying cost of additional electricity supply.

Actual utility tariffs do not reflect this ideal because of political concerns about the effects of large fixed monthly charges on low‐​income customers and the optics of explaining to customers that they must pay 50 or 60 dollars a month for access even if their use is zero. Instead, the current pricing system “taxes” electricity use to pay for fixed costs. And solar net metering is simply a way to avoid the tax. The proposed California rate reforms would explicitly impose a fixed monthly charge on rooftop solar systems that are also connected to the grid, a change that could bring major changes to your electric bill statewide, and would thus end the fixed‐​cost avoidance. Any distributional concerns that arise because of the effect of much larger fixed charges on lower‐​income customers could be managed through explicit tax deductions that are proportional to income.

The current rooftop solar subsidies in California also should end because they have perverse incentive effects on fossil fuel generators, even as the state exports its energy policies to neighbors. Solar output has increased so much in California that when it ends with every sunset, natural gas generated electricity has to increase very rapidly. But the natural gas generators whose output can be increased rapidly have more pollution and higher marginal costs than those natural gas plants (so called combined cycle plants) whose output is steadier. The rapid increase in California solar capacity has had the perverse effect of changing the composition of natural gas generators toward more costly and polluting units.

The reforms would not end the role of solar power. They would just shift production from high‐​cost rooftop to lower‐​cost centralized solar production, a transition cited in analyses of why electricity prices are soaring in California, whose average costs are comparable with electricity production in natural gas generators. And they would end the excessive subsidies to solar that have negatively altered the composition of natural gas generators.

Getting prices right does not generate citizen interest as much as the misguided notion that rooftop solar will save the world, and recent efforts to overturn income-based utility charges show how politicized the debate remains. But getting prices right would allow the decentralized choices of consumers and investors to achieve their goals at least cost.

Opinion: Now is the time for a western Canadian electricity grid

Western Canada Electric Grid could deliver interprovincial transmission, reliability, peak-load support, reserve sharing, and wind and solar integration, lowering costs versus new generation while respecting AESO markets and Crown utility structures.

 

Key Points

Interprovincial transmission to share reserves, boost reliability, integrate wind and solar, and cut peak capacity costs.

✅ Cuts reserve margins via diversity of peak loads

✅ Enables wind and solar balancing across provinces

✅ Saves ratepayers vs replacing retiring thermal plants

 

The 2017 Canadian Free Trade Agreement does not do much to encourage provinces to trade electric energy east and west. Would a western Canada electric grid help electricity consumers in the western provinces? Some Alberta officials feel that their electric utilities are investor owned and they perceive the Crown corporations of BC Hydro, SaskPower and Manitoba Hydro to be subsidized by their provincial governments, so an interprovincial electric energy trade would not be on a level playing field.

Because of the limited trade of electric energy between the western provinces, each utility maintains an excessive reserve of thermal and hydroelectric generation greater than their peak loads, to provide a reliable supply during peak load days as grids are increasingly exposed to harsh weather across Canada. This excess does not include variable wind and solar generation, which within a province can’t be guaranteed to be available when needed most.

This attitude must change. Transmission is cheaper than generation, and coordinated macrogrids can further improve reliability and cut costs. By constructing a substantial grid with low profile and aesthetically designed overhead transmission lines, the excess reserve of thermal and hydroelectric generation above the peak electric load can be reduced in each province over time. Detailed assessments will ensure each province retains its required reliability of electric supply.

As the provinces retire aging thermal and coal-fired generators, they only need to replace them to a much lower level, by just enough to meet their future electric loads and Canada's net-zero grid by 2050 goals. Some of the money not spent in replacing retired generation can be profitably invested in the transmission grid across the four western provinces.

But what about Alberta, which does not want to trade electric energy with the other western provinces? It can carry on as usual within the Alberta Electric System Operator’s (AESO) market and will save money by keeping the installed reserve of thermal and hydroelectric generation to a minimum. When Alberta experiences a peak electric load day and some generators are out of service due to unplanned maintenance, it can obtain the needed power from the interprovincial electric grid. None of the other three western provinces will peak at the same time, because of different weather and time zones, so they will have spare capacity to help Alberta over its peak. The peak load in a province only lasts for a few hours, so Alberta will get by with a little help from its friends if needed.

The grid will have no energy flowing on it for this purpose except to assist a province from time to time when it’s unable to meet its peak load. The grid may only carry load five per cent of the time in a year for this purpose. Under such circumstances, the empty grid can then be used for other profitable markets in electric energy. This includes more effective use of variable wind and solar energy, by enabling a province to better balance such intermittent power as well as allowing increased installation of it in every province. This is a challenge for AESO which the grid would substantially ease.

Natural Resources Canada promoted the “Regional Electricity Co-Operative and Strategic Infrastructure” initiative for completion this year and contracted through AESO, alongside an Atlantic grid study to explore regional improvements. This is a first step, but more is needed to achieve the full benefit of a western grid.

In 1970 a study was undertaken to electrically interconnect Britain with France, which was justified based on the ability to reduce reserve generation in both countries. Initially Britain rejected it, but France was partially supportive. In time, a substantial interconnection was built, and being a profitable venture, they are contemplating increasing the grid connections between them.

For the sake of the western consumers of electricity and to keep electricity rates from rising too quickly, as well as allowing productive expansion of wind and solar energy in places like British Columbia's clean energy shift efforts, an electric grid is essential across western Canada.

Dennis Woodford is president of Electranix Corporation in Winnipeg, which studies electric transmission problems, particularly involving renewable energy generators requiring firm connection to the grid.

British Columbia Fuels Up for the Future with $900 Million Hydrogen Project

H2 Gateway Hydrogen Network accelerates clean energy in B.C., building electrolysis plants and hydrogen fueling stations for zero-emission vehicles, heavy-duty trucks, and long-haul transit, supporting decarbonization, green hydrogen supply, and infrastructure investment.

 

Key Points

A $900M B.C. initiative by HTEC to build electrolysis plants and 20 hydrogen fueling stations for zero-emission transport.

✅ $900M project with HTEC, CIB, and B.C. government

✅ 3 electrolysis plants plus byproduct liquefaction in North Vancouver

✅ Up to 20 stations; 14 for heavy-duty vehicles in B.C. and Alberta

 

British Columbia is taking a significant step towards a cleaner future with a brand new $900 million project. This initiative, spearheaded by hydrogen company HTEC and supported by the CIB in B.C. and the B.C. government, aims to establish a comprehensive hydrogen network across the province. This network will encompass both hydrogen production plants and fueling stations, marking a major leap in developing hydrogen infrastructure in B.C.

The project, dubbed "H2 Gateway," boasts several key components. At its core lies the construction of three brand new electrolysis hydrogen production plants. These facilities will be strategically located in Burnaby, Nanaimo, and Prince George, ensuring a wide distribution of hydrogen fuel. An additional facility in North Vancouver will focus on liquefying byproduct hydrogen, maximizing resource efficiency.

The most visible aspect of H2 Gateway will undoubtedly be the network of hydrogen fueling stations. The project envisions up to 20 stations spread across British Columbia and Alberta, complementing the province's Electric Highway build-out, with 18 being situated within B.C. itself. This extensive network will significantly enhance the accessibility of hydrogen fuel, making it a more viable option for motorists. Notably, 14 of these stations will be designed to handle heavy-duty vehicles, catering to the transportation sector's clean energy needs.

The economic and environmental benefits of H2 Gateway are undeniable. The project is expected to generate nearly 300 jobs, aligning with recent grid job creation efforts, providing a much-needed boost to the B.C. economy. More importantly, the widespread adoption of hydrogen fuel promises significant reductions in greenhouse gas emissions. Hydrogen-powered vehicles produce zero tailpipe emissions, making them a crucial tool in combating climate change.

British Columbia's investment in hydrogen infrastructure aligns with a global trend. As countries strive to achieve ambitious climate goals, hydrogen is increasingly viewed as a promising clean energy source. Hydrogen fuel cells offer several advantages over traditional electric vehicles, and while B.C. leads the country in going electric, they boast longer driving ranges and shorter refueling times, making them particularly attractive for long-distance travel and heavy-duty applications.

While H2 Gateway represents a significant step forward, challenges remain. The production of clean hydrogen, often achieved through electrolysis using renewable energy sources, faces power supply challenges and requires substantial initial investment. Additionally, the number of hydrogen-powered vehicles on the road is still relatively low.

However, projects like H2 Gateway are crucial in overcoming these hurdles. By creating a robust hydrogen infrastructure, B.C. is sending a strong signal to the industry and, alongside BC Hydro's EV charging expansion across southern B.C., is building a comprehensive clean transportation network. This investment will not only benefit the environment but also incentivize the development and adoption of hydrogen-powered vehicles. As the technology matures and production costs decrease, hydrogen fuel has the potential to revolutionize transportation and play a key role in a sustainable future.

The road ahead for hydrogen may not be entirely smooth, but British Columbia's commitment to H2 Gateway demonstrates a clear vision. By investing in clean energy infrastructure, the province is not only positioning itself as a leader in the fight against climate change, with Canada and B.C. investing in green energy solutions to accelerate progress, but also paving the way for a more sustainable transportation landscape.

Effort to make Philippines among best power grids in Asia

NGCP-SGCC Partnership drives transmission grid modernization in the Philippines, boosting high-voltage capacity, reliability, and resilience, while developing engineering talent via the Trailblazers Program to meet Southeast Asia best practices and utility standards.

 

Key Points

A partnership to modernize the Philippines' grid, boost high-voltage capacity, and upskill NGCP engineers.

✅ Modernizes transmission assets and grid reliability nationwide

✅ Trailblazers Program develops NGCP's engineering leadership

✅ SGCC knowledge transfer on UHV, high-voltage, and best practices

 

The National Grid Corp. of the Philippines (NGCP) is building on its partnership with State Grid Corp of China (SGCC) to expand and modernize transmission facilities, as well as enhance the capabilities of its personnel to advance the country's grid network, aligning with smart grid transformation in Egypt seen in other markets. NGCP Internal Affairs Department head Edwin Natividad said the grid operator is implementing various development programs with SGCC to make the country's power grid among the best power utilities in Asia.

"We have to look at policies aligned with best global practices, including smart grid solutions increasingly adopted worldwide, that we can choose in adopting in the Philippines too," he said. One of NGCP's flagship development program is the Trailblazers Program, the company's strategy to further develop engineers "who will not just be technical experts, but also be the change agents and movers in the NGCP organization as well as in the Philippines' power sector," Natividad said.

"Having the support of the largest utility in the world gives us comfort that this program is designed and implemented by the best in the power industry," he said. Under the program, high performing personnel participating will be prepared for bigger roles later on in their careers at NGCP.

Business ( Article MRec ), pagematch: 1, sectionmatch: 1 "The advantage of such a pool is that it provides flexibility and, eventually, organizational self-sufficiency around the current and future talent needs of NGCP," Natividad said. Now on its third edition, the Trailblazers Program has already sent 76 personnel since it started in November 2016. Natividad said more than 16 of those who previously attended similar programs have already assumed higher roles in NGCP.

Apart from technical skills development, NGCP's partnership with SGCC also provides technical development to improve on the physical transmission assets. "If you will compare the facilities being handled by SGCC with other countries, in terms of handling high voltage capability, SGCC is way ahead.

The higher the voltage it's going to be more difficult to handle," Natividad said, adding they can handle more power to distribute to power distributors. As an example, SGCC's transmission facilities can handle high voltage to as much as 1,000 kiloVolts (kV), whereas the Philippines only has one high voltage facility, the interconnection between Luzon and Visayas, which can handle 500 kV, echoing proposals for macrogrids in Canada to improve reliability.

Natividad said NGCP was the first and biggest investment of SGCC outside of China before it made investments in other parts of the world, even as cybersecurity concerns in Britain have influenced supplier choices. A consortium among businessmen Henry Sy Jr., Robert Coyuito Jr., and SGCC as technical partner, NGCP holds a 25-year concession contract to operate and maintain the country's transmission grid.

Earlier, Sy, NGCP president and CEO, said the company is targeting to become the best utility firm in Southeast Asia. Since it took over the operations and maintenance of the country's power transmission network in 2009, the grid operator has introduced major physical and technological upgrades to ageing state-owned lines and facilities, while in Great Britain an independent operator model is being advanced to reshape system operations.
