Summerside Wind Power reached 61% in May, blending renewable energy, municipal utility operations, and P.E.I. wind farms, driving city revenue, advancing green city goals, and laying groundwork for smart grid integration.

Key Points

Summerside Wind Power is the city utility's wind supply, 61% in May, generating revenue that supports local services.

✅ 61% of electricity in May from wind; annual target 45%.

✅ Mix of city-owned farm and West Cape Wind Farm contract.

✅ Revenues projected at $2.9M; funds municipal budget and services.

During the month of May, 61 per cent of the electricity Summerside's homes, businesses and industries used came from wind power sources.

25 per cent was purchased from the West Cape Wind Farm in West Point, P.E.I. — the city has had a contract with it since 2007. The other 36 per cent came from the city's own wind farm, which was built in 2009. 

"One of the strategic goals that was planned for by the city back in 2005 was to try to become a 100 per cent green city," said Greg Gaudet, Summerside's director of municipal services.

"The city started looking at ways it could adopt green practices into its operations on everything it owns and operates and provides services to the community."

Summerside Electric powers about 6,200 residential, 970 commercial and 30 industrial customers and also sells to NB Power, while Nova Scotia Power now generates 30 per cent of its electricity from renewables.

The Summerside Wind Farm is owned by the City of Summerside, which then sells the electricity to Summerside Electric, which it also owns, for profit. 

For the months of April and May, the wind farm generated $630,000 for the city. Last year, it was $507,000 over the same time frame, which does not include a 2 per cent rate increase imposed this year.

"We had a lot of good, strong days of wind for the month of May over other years. So normally we'd be on average somewhere in the range of the 45 per cent range for those months," said Gaudet. 

The city's annual target for wind generation is also 45 per cent, which aligns with the view that more energy sources make better projects. Gaudet said it balances out over the year, with winter being the best and production dropping as low as 25 per cent in the summer months.

At Summerside council's monthly meeting on Monday, May's 61 per cent figure was touted as one of the highest months on record.

"To have one at 61 per cent means we had great production from our wind facilities and contracts, though communities such as Portsmouth have raised turbine noise and flicker concerns in other contexts," Gaudet said.

The utility also owns and provides power through a diesel generation plant.

Municipal money maker
The municipality projects its wind energy production will generate $2.9 million for the city in its current fiscal year, which began April 1, paralleling job gains seen in Alberta's renewables surge this year.

"Any revenues that are received from the wind farm facility goes into the City of Summerside budget," Gaudet said. "Then the council decides on how that money is accrued and where it goes and what it supports in the community."

Wind power generated $2.89 million for the city in the 2019-2020 fiscal year. The budget originally projected $3.2 million in revenue, but blade damage sustained during post-tropical storm Dorian put two turbines out of commission for a few weeks.

Gaudet called this their "only bad year" and officials said they see this year's target to be a bit more conservative and achievable regardless of hiccups and uncontrollable forces, such as the wind they're harnessing.

"It's performed outstandingly well," said Gaudet of the operation.

"There's been no huge, major cost factors with the wind farm to date ... its production has been fairly consistent from year to year." 

Gaudet said the technology has already been piloted at a smaller operation at Credit Union Place, aligning with municipal solar power projects elsewhere.

The goal of the project is to bring Summerside's renewable portfolio up to a yearly average of 62 per cent. Gaudet said it's expected to be commissioned by May 2022 at the latest and after that, the city hopes to focus on smart grid technology.

"It's a long-term goal and I think it's the right [investment] to make," he said. "You have to be environmentally conscious and a steward of your community.

"I think Summerside is that and does that ... a model for North America to look at how a city can work a relationship with an electric utility for the betterment."

Ontario Industrial Electricity Pricing Reforms aim to cut regulatory burden for industrial ratepayers through an energy concierge service, IESO billing reviews, GA estimation enhancements, clearer peak demand data, and contract cost savings.

Key Points

Measures to reduce industrial power costs via an energy concierge, IESO and GA reviews, and better peak demand data.

✅ Energy concierge eases pricing and connection inquiries

✅ IESO to simplify bills and refine GA estimation

✅ Real-time peak data and contract savings under review

Ontario's government is pursuing burden reduction measures for industrial electricity ratepayers, including legislation to lower rates to help businesses compete, and stimulate growth and investment.

Over the next year, Ontario will help industrial electricity ratepayers focus on their businesses instead of their electricity management practices by establishing an energy concierge service to provide businesses with better customer service and easier access to information about electricity pricing and changes for electricity consumers as well as connection processes.

Ontario is also tasking the Independent Electricity System Operator (IESO) to review and report back on its billing, settlement and customer service processes, building on initiatives such as electricity auctions that aim to reduce costs.

Improve and simplify industrial electricity bills, including clarifying the recovery rate that affects charges;

Review how the monthly Global Adjustment (GA) charge is estimated and identify potential enhancements related to cost allocation across classes; and,

Improve peak demand data publication processes and assess the feasibility of using real-time data to determine the factors that allocate GA costs to consumers.

Further, as part of the government's continued effort to finding efficiencies in the electricity system, Ontario is also directing IESO to review generation contracts to find opportunities for cost savings.

These measures are based on industry feedback received during extensive industrial electricity price consultations held between April and July 2019, which underscored how high electricity rates have impacted factories across the province.

"Our government is focused on finding workable electricity pricing solutions that will provide the greatest benefit to Ontario," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Reducing regulatory burden on businesses can free up resources that can then be invested in areas such as training, new equipment and job creation."

The government is also in the process of developing further changes to industrial electricity pricing policy, amid planned rate increases announced by the OEB, informed by what was heard during the industrial electricity price consultations.

"It's important that we get this right the first time," said Minister Rickford. "That's why we're taking a thoughtful approach and listening carefully to what businesses in Ontario have to say."

Helping industrial ratepayers is part of the government's balanced and prudent plan to build Ontario together through ensuring our province is open for business and building a more transparent and accountable electricity system.

Crosbie Hydro Energy Action Plan outlines rate mitigation for Muskrat Falls, leveraging Nalcor oil revenues, export sales, Holyrood savings, and potential Hydro-Quebec taxation to keep Newfoundland and Labrador electricity rates near 14.67 cents/kWh.

Key Points

PC plan to cap post-Muskrat rates by using Nalcor revenues, exports, and savings, with optional Accord funds.

✅ $575.4M yearly to hold rates near 14.67 cents/kWh

✅ Sources: Nalcor oil $231M, Holyrood $150M, rates/dividends $123.4M

✅ Options: export sales, restructuring, Atlantic Accord, HQ tax

Newfoundland and Labrador PC Leader Ches Crosbie says Muskrat Falls won't drive up electricity rates, a goal consistent with an agreement to shield ratepayers from cost overruns, if he's elected premier.

According to Crosbie, who presented the party's Crosbie Hydro Energy Action Plan — acronym CHEAP — at a press conference Monday, $575.4 million is needed per year in order to keep rates from ballooning past 14.67 cents per kilowatt hour.

Here's where he thinks the money could come from:

• Hydro rates and dividends — $123.4 million
• Export sales — $40.1 million
• Nalcor restructuring — $30 million
• Holyrood savings — $150  million
• Nalcor oil revenue — $231 million

The oil money, Crosbie said, isn't going into government coffers but being invested into the offshore which, he said, is a good place for it.

"But the plan from the beginning around Muskrat Falls was that if there was need for it — for mitigation for rates — that those revenues and operating cash flows from Nalcor oil and gas would be available to be recycled into rate mitigation, as reflected in a recent financial update on the pandemic's impact. and that's what we're going to have to do," he said.

According to Crosbie, his numbers come from the preliminary stage of the Public Utilities Board process, even as rate mitigation talks have lacked public details.

"I'm telling you this is the best information available to anyone outside of government," he said. "We're working on what we can."

The PUB estimated Nalcor restructuring could save between $10 million and $15 million, according to Crosbie, but he figures there's "enough duplication and overpayment involved in the way things are now set up that we can find $30 million there."

Currently, provincial ratepayers pay about 12 cents per kilowatt hour as electricity users have started paying for Muskrat Falls costs.

Crosbie's $575.4-million figure would put rates at 14.67 cents per kilowatt-hour in 2021, where his plan pledges to keep them.

A recent Public Utilities Board Report says there's a potential $10 million to $15 million in savings from Nalcor, but Crosbie says he can find $30 million. (CBC)

"The promise is that Muskrat Falls, when it comes online — comes in service — will not increase your rates. Between now and when that happens there are rate increases already in the pipeline up to that level of [14.67 cents per kilowatt-hour] … so that is the baseline target rate at which rates will be kept.

"In other words, Muskrat will not drive up prices for electricity to consumers beyond that point."

In addition to those savings, Crosbie's plan outlined two further steps.

"We think it could be done out of the resources that I've just identified now, but if there's a problem with that, and as a temporary measure, we can use a modest amount of the Atlantic Accord review, fiscal review, revenues," he said.

Plan 'nothing new'

Premier Dwight Ball slammed the plan at the House of Assembly on Monday, saying it lacked insight.

"It was a copy and paste exercise," he told reporters. "There's nothing new in that plan. Not at all."

"We're not leaving any stone unturned of where the opportunity would be to actually generate revenue," he said.  "We are genuinely concerned about rate mitigation and we've got to get a plan in place."

Potential to tax Hydro-Québec

Crosbie also said there's potential to tax Hydro-Québec.

According to Crosbie, tax exemptions that expired in 2016 allow the province to tax exports from the Upper Churchill, which, he said, could result in "hundreds of millions or billions" in revenue.

"It's not my philosophy to immediately go and do that because that would generate litigation — who needs more of that? — but we do need to let Quebec know that we're very aware of that, and aware of that opportunity, and invite them to come talk about a whole host of issues," Crosbie said.

Crosbie said the tax would also have to be applied to domestic consumption.

"But so massive is the potential revenue from the Upper Churchill export that there would be ways to mitigate that and negate the effect of that on consumers in the province."

Crosbie said with the Atlantic Accord revenue, he could still present a balanced budget by 2022.

Alberta Solar Energy Expansion confronts high installation costs, grid integration and storage needs, and environmental impact, while incentives, infrastructure upgrades, and renewable targets aim to balance reliability, land use, and emissions reductions provincewide.

Key Points

Alberta Solar Energy Expansion is growth in solar tempered by costs, grid limits, environmental impact, and incentives.

✅ High capex and financing challenge utility-scale projects

✅ Grid integration needs storage, transmission, and flexibility

✅ Site selection must mitigate land and wildlife impacts

Alberta's push towards expanding solar power is encountering significant financial and environmental hurdles. The province's ambitious plans to boost solar power generation have been met with both enthusiasm and skepticism as stakeholders grapple with the complexities of integrating large-scale solar projects into the existing energy framework.

The Alberta government has been actively promoting solar energy as part of its strategy to diversify the energy mix in a province that is a powerhouse for both green energy and fossil fuels today and reduce greenhouse gas emissions. Recent developments have highlighted the potential of solar power to contribute to Alberta's clean energy goals. However, the path forward is fraught with challenges related to costs, environmental impact, and infrastructure needs.

One of the primary issues facing the solar energy sector in Alberta is the high cost of solar installations. Despite decreasing costs for solar technology in recent years, the upfront investment required for large-scale solar farms remains substantial, even as some facilities have been contracted at lower cost than natural gas in Alberta today. This financial barrier has led to concerns about the economic viability of solar projects and their ability to compete with other forms of energy, such as natural gas and oil, which have traditionally dominated Alberta's energy landscape.

Additionally, there are environmental concerns associated with the development of solar farms. While solar energy is considered a clean and renewable resource, the construction of large solar installations can have environmental implications. These include potential impacts on local wildlife habitats, land use changes, where approaches like agrivoltaics can co-locate farming and solar, and the ecological effects of large-scale land clearing. As solar projects expand, balancing the benefits of renewable energy with the need to protect natural ecosystems becomes increasingly important.

Another significant challenge is the integration of solar power into Alberta's existing energy grid. Solar energy production is variable and dependent on weather conditions, especially with Alberta's limited hydro capacity for flexibility, which can create difficulties in maintaining a stable and reliable energy supply. The need for infrastructure upgrades and energy storage solutions is crucial to address these challenges and ensure that solar power can be effectively utilized alongside other energy sources.

Despite these challenges, the Alberta government remains committed to advancing solar energy as a key component of its renewable energy strategy. Recent initiatives include financial incentives and support programs aimed at encouraging investment in solar projects and supporting a renewable energy surge that could power thousands of jobs across Alberta today. These measures are designed to help offset the high costs associated with solar installations and make the technology more accessible to businesses and homeowners alike.

Local communities and businesses are also playing a role in the growth of solar energy in Alberta. Many are exploring opportunities to invest in solar power as a means of reducing energy costs and supporting sustainability efforts and, increasingly, to sell renewable energy into the market as demand grows. These smaller-scale projects contribute to the overall expansion of solar energy and demonstrate the potential for widespread adoption across the province.

The Alberta government has also been working to address the environmental concerns associated with solar energy development. Efforts are underway to implement best practices for minimizing environmental impacts and ensuring that solar projects are developed in an environmentally responsible manner. This includes conducting environmental assessments and working with stakeholders to address potential issues before projects are approved and built.

In summary, while Alberta's solar energy initiatives hold promise for advancing the province's clean energy goals, they are also met with significant financial and environmental challenges. Addressing these issues will be crucial to the successful expansion of solar power in Alberta. The government's ongoing efforts to support solar projects through incentives and infrastructure improvements, coupled with responsible environmental practices, will play a key role in determining the future of solar energy in the province.

Site C 500 kV transmission lines strengthen the BC Hydro grid, linking the new substation and Peace Canyon via a 75 kilometre right-of-way to deliver clean energy, with 400 towers built and both circuits energized.

Key Points

High-voltage lines connecting Site C substation to the BC Hydro grid, delivering clean energy via Peace Canyon.

✅ Two 75 km circuits between Site C and Peace Canyon

✅ Connect new 500 kV substation to BC Hydro grid

✅ Over 400 towers built along existing right-of-way

The second and final 500 kilovolt, 75 kilometre transmission line on the Site C project, which has faced stability questions in recent years, has been completed and energized.

With this milestone, the work to connect the new Site C substation to the BC Hydro grid, amid treaty rights litigation that has at times shaped schedules, is complete. Once the Site C project begins generating electricity, much like when the Maritime Link first power flowed between Newfoundland and Nova Scotia, the transmission lines will help deliver clean energy to the rest of the province.

The two 75 kilometre transmission lines run along an existing right-of-way between Site C and the Peace Canyon generating station, a route that has seen community concerns from some northerners. The project’s first 500 kilovolt, 75 kilometre transmission line – along with the Site C substation – were both completed and energized in the fall of 2020.

BC Hydro awarded the Site C transmission line construction contract to Allteck Line Contractors Inc. (now Allteck Limited Partnership) in 2018. Since construction started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines, even as other interties like the Manitoba-Minnesota line have faced scheduling uncertainty, over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, comparable to initiatives such as the New England Clean Power Link in scale, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals.

Work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation, similar to milestones on the Maritime Link project, is still underway. This work is expected to be complete in 2023.

Calistoga Resiliency Centre Microgrid delivers grid resilience via green hydrogen and BESS, providing island-mode backup during PSPS events, wildfire risk, and outages, with black-start and grid-forming capabilities for reliable community power.

Key Points

A hybrid green hydrogen and BESS facility ensuring resilient, islanded power for Calistoga during PSPS and outages.

✅ 293 MWh capacity with 8.5 MW peak for critical backup

✅ Hybrid lithium-ion BESS plus green hydrogen fuel cells

✅ Island mode with black-start and grid-forming support

Energy Vault, a prominent energy storage and technology company known for its gravity storage, recently secured US$28 million in project financing for its innovative Calistoga Resiliency Centre (CRC) in California. This funding will enable the development of a microgrid powered by a unique combination of green hydrogen and battery energy storage systems (BESS), marking a significant step forward in enhancing grid resilience in the face of natural disasters such as wildfires.

Located in California's fire-prone regions, the CRC is designed to provide critical backup power during Public Safety Power Shutoff (PSPS) events—periods when utility companies proactively cut power to prevent wildfires. These events can leave communities without electricity for extended periods, making the need for reliable, independent power sources more urgent as many utilities see benefits in energy storage today. The CRC, with a capacity of 293 MWh and a peak output of 8.5 MW, will ensure that the Calistoga community maintains power even when the grid is disconnected.

The CRC features an integrated hybrid system that combines lithium-ion batteries and green hydrogen fuel cells, even as some grid-scale projects adopt vanadium flow batteries for long-duration needs. During a PSPS event or other grid outages, the system will operate in "island mode," using hydrogen to generate electricity. This setup not only guarantees power supply but also contributes to grid stability by supporting black-start and grid-forming functions. Energy Vault's proprietary B-VAULT DC battery technology complements the hydrogen fuel cells, enhancing the overall performance and resilience of the microgrid.

One of the key aspects of the CRC project is the utilization of green hydrogen. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen is generated through renewable energy sources like solar or wind power, with large-scale initiatives such as British Columbia hydrogen project accelerating supply, making it a cleaner and more sustainable alternative. This aligns with California’s ambitious clean energy goals and is expected to reduce the carbon footprint of the region’s energy infrastructure.

The CRC project also sets a precedent for future hybrid microgrid deployments across California and other wildfire-prone areas, with utilities like SDG&E Emerald Storage highlighting growing adoption. Energy Vault has positioned the CRC as a model for scalable, utility-scale microgrids that can be adapted to various locations facing similar challenges. Following the success of this project, Energy Vault is expanding its portfolio with additional projects in Texas, where it anticipates securing up to US$25 million in financing.

The funding for the CRC also includes the sale of an investment tax credit (ITC), a key component of the financing structure that helps make such ambitious projects financially viable. This structure is crucial as it allows companies to leverage government incentives to offset development costs, including CEC long-duration storage funding, thus encouraging further investment in green energy infrastructure.

Despite some skepticism regarding the transportation of hydrogen rather than producing it onsite, the project has garnered strong support. California’s Public Utilities Commission (CPUC) acknowledged the potential risks of transporting green hydrogen but emphasized that it is still preferable to using more harmful fuel sources. This recognition is important as it validates Energy Vault’s approach to using hydrogen as part of a broader strategy to transition to clean, reliable energy solutions.

Energy Vault's shift from its traditional gravity-based energy storage systems to battery energy storage systems, such as BESS in New York, reflects the company's adaptation to the growing demand for versatile, efficient energy solutions. The hybrid approach of combining BESS with green hydrogen represents an innovative way to address the challenges of energy storage, especially in regions vulnerable to natural disasters and power outages.

As the CRC nears mechanical completion and aims for full commercial operations by Q2 2025, it is poised to become a critical part of California’s grid resilience strategy. The microgrid's ability to function autonomously during emergencies will provide invaluable benefits not only to Calistoga but also to other communities that may face similar grid disruptions in the future.

Energy Vault’s US$28 million financing for the Calistoga Resiliency Centre marks a significant milestone in the development of hybrid microgrids that combine the power of green hydrogen and battery energy storage. This project exemplifies the future of energy resilience, showcasing a forward-thinking approach to mitigating the impact of natural disasters and ensuring a reliable, sustainable energy future for communities at risk. With its innovative use of renewable energy sources and cutting-edge technology, the CRC sets a strong example for future energy storage projects worldwide.
