McGuinty says no to carbon tax

PGE Residential Energy Storage Pilot aggregates 525 home batteries into a virtual power plant, enabling distributed energy resources, smart grid control, renewable energy optimization, demand response, and backup power across Portland General Electric's area.

Key Points

A PGE program aggregating 525 batteries into a utility-run virtual power plant for renewables support and backup power.

✅ Up to 4 MW aggregated capacity from 525 residential batteries

✅ Monthly credits: $40 ($20 with solar) for grid services

✅ Enhances smart grid, DERs, resilience, and outage backup

Portland General Electric Company is set to launch a pilot program that will incentivize installation and connection of 525 residential energy storage batteries that PGE will dispatch, contributing up to four megawatts of energy to PGE's grid. The distributed assets will create a virtual power plant made up of small units that can be operated individually or combined to serve the grid, adding flexibility that supports PGE's transition to a clean energy future. When the program launches this fall, incentives will be available to residential customers across PGE's service area. Rebates will be available to customers within three neighborhoods participating in PGE's Smart Grid Test Bed, and income-qualified customers participating in Energy Trust of Oregon's Solar Within Reach offer.

PGE will study the full benefits of energy storage that these distributed energy assets can provide the grid while also increasing resiliency for each participating customer. PGE will operate and test the benefits of using homes' batteries, each capable of storing 12 to 16 kWh of energy, to optimize the use of renewable energy and grid capabilities. In the event of a power outage, participating customers can rely on them as a backup power resource.

"Our vision for clean energy relies on a smart, integrated grid. One of the ways that we'll achieve that is through creative partnerships and diversified energy resources, including those behind-the-meter," said Larry Bekkedahl, vice president of Grid Architecture, Integration and Systems Operation. "This pilot project will allow PGE to integrate even more intermittent renewable energy and enhance grid capabilities while also giving participating customers peace of mind in the event of an outage."

Energy storage maximizes renewables and the grid, improves power quality

Energy storage, including long-duration energy storage solutions, is vital to help capture and store energy from renewable power sources, such as wind and solar, that are more variable. As a virtual power plant, the residential battery storage pilot will create a single resource that can help the grid balance energy production with energy demand, freeing up the generation resources that are typically held on standby, ready to kick in when the wind doesn't blow or the sun doesn't shine. As a clean energy option that takes the place of standby resources, the virtual power plant also gives customers access to reliable energy, even in the event of system outages.

The test program will also allow PGE to test new smart-grid control devices across its distribution system that will more effectively allow a two-way exchange between PGE and pilot participants. The new controls will more actively manage the way that electricity is distributed across PGE's system to incorporate energy that customers generate, such as through solar panels, while also meeting power demand that is less predictable, such as for charging electric vehicles, supporting EVs for grid stability strategies. The controls will allow PGE to more actively manage power distribution to improve power quality for all customers.

Select rebates and incentives will be available to participants, aligned with electric vehicle programs that encourage transportation electrification

When it launches in fall 2020, participation in the program will be available to residential customers, including:

* Those across PGE's service area who already have or are installing a qualifying battery. Participation will require an application, and in exchange for allowing PGE to operate their battery for grid services, similar to programs where EV owners selling power back for compensation, participating customers will receive a monthly bill credit of $40, or $20 if the battery is charged with solar power.

* Customers across PGE's service area who are participating in the Solar Within Reach offering from Energy Trust of Oregon. Participants will be eligible for a $5,000 instant rebate in addition to the monthly bill credits.

* Those living within the PGE Smart Grid Test Bed who purchase a battery will be eligible for an instant rebate, in addition to the monthly bill credit of $40 or $20, which will allow PGE to test the localized grid impact of having a large concentration of battery storage devices available on one substation and explore interfaces with vehicle-to-grid pilots in the region.

PGE is working with Energy Trust to cost-effectively procure the residential battery storage systems, as utilities invest in advanced storage solutions across the region, by leveraging the existing Solar incentive program infrastructure and trade ally contractor network. Customers who participate in the program will own their battery systems, and rebates will only be available for systems installed by an Energy Trust solar trade ally. The program may also accept customers with a qualifying battery that is was previously installed, following a process to ensure safe operation.

Cabin Creek Solar Project Montana delivers 150 MW of utility-scale solar under a Power Purchase Agreement, with Basin Electric and Clenera supplying renewable energy, enhancing grid reliability, and reducing carbon emissions for 30,000 homes.

Key Points

A 150 MW solar PPA near Baker by Basin Electric and Clenera, delivering reliable renewable power and carbon reduction.

✅ 150 MW across two 75 MW sites near Baker, Montana

✅ PPA supports Basin Electric's diverse, cost-effective portfolio

✅ Cuts 265,000 tons CO2 and powers 30,000 homes

A new solar project in Montana will provide another 150 megawatts (MW) of affordable, renewable power to Basin Electric customers and co-op members across the region.

Basin Electric Power Cooperative (Basin Electric) and Clenera Renewable Energy, announced today the execution of a Power Purchase Agreement (PPA) for the Cabin Creek Solar Project. Cabin Creek is Basin Electric's second solar PPA, and the result of the cooperative's continuing goal of providing a diverse mix of energy sources that are cost-effective for its members.

When completed, Cabin Creek will consist of two, 75-MW projects in southeastern Montana, five miles west of Baker. According to Clenera, the project will eliminate 265,000 tons of carbon dioxide per year and power 30,000 homes, while communities such as the Ermineskin First Nation advance their own generation efforts.

"Renewable technology has advanced dramatically in recent years, with rapid growth in Alberta underscoring broader trends, which means even more affordable power for Basin Electric's customers," said Paul Sukut, CEO and general manager of Basin Electric. "Basin Electric is excited to purchase the output from this project to help serve our members' growing energy needs. Adding solar further promotes our all-of-the-above energy solution as we generate energy using a diverse resource portfolio including coal, natural gas, and other renewable resources to provide reliable, affordable, and environmentally safe generation.

"Clenera is proud to partner with Basin Electric Power Cooperative to support the construction of the Cabin Creek Solar projects in Montana," said Jared McKee, Clenera's director of Business Development. "We truly believe that Basin Electric will be a valuable partner as we aim to deliver today's new era of reliable, battery storage increasingly enabling round-the-clock service, affordable, and clean energy."

"We're pleased that Southeast Electric will be home to the Cabin Creek Solar Project," said Jack Hamblin, manager of Southeast Electric Cooperative, a Basin Electric Class C member headquartered in Ekalaka, Montana. "This project is one more example of cooperatives working together to use economies of scale to add affordable generation for all their members - similar to what was done 70 years ago when cooperatives were first built."

Basin Electric Class A member Upper Missouri Power Cooperative, headquartered in Sidney, Montana, provides wholesale power to Southeast Electric and 10 other distribution cooperatives in western North Dakota and eastern Montana. "It is encouraging to witness the development of cost-competitive energy, including projects in Alberta contracted at lower cost than natural gas that demonstrate market shifts, like the Cabin Creek Solar Project, which will be part of the energy mix we purchase from Basin Electric for our member systems, said Claire Vigesaa, Upper Missouri's general manager. "The energy needs in our region are growing and this project will help us serve both our members, and our communities as a whole."

Cabin Creek will bring significant economic benefits to the local area. According to Clenera, the project will contribute $8 million in property taxes to Fallon County and $5 million for the state of Montana over 35 years. They say it will also create approximately 300 construction jobs and two to three full-time jobs.

"This project underscores the efforts by Montana's electric cooperatives to continue to embrace more carbon-free technology," said Gary Wiens, CEO of Montana Electric Cooperatives' Association. "It also demonstrates Basin Electric's commitment to seek development of renewable energy projects in our state. It's exciting that these two projects combined are 50 times larger than our current largest solar array in Montana."

Cabin Creek is anticipated to begin operations in late 2023.

U.S. Power Grid Supply Shortages strain reliability as heat waves, hurricanes, and drought drive peak demand; transformer scarcity, gas constraints, and renewable delays raise outage risks across ERCOT and MISO, prompting FERC warnings.

Key Points

They are equipment and fuel constraints that, amid extreme weather and peak demand, elevate outage risks.

✅ Transformer shortages delay storm recovery and repairs.

✅ Record gas burn, low hydro tighten generation capacity.

✅ ERCOT and MISO warn of rolling outages in heat waves.

U.S. power companies are facing supply crunches amid the U.S. energy crisis that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, reflecting unprecedented electricity demand across the Eastern U.S., which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter, after the Texas power system failure highlighted cold-weather vulnerabilities, as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

"Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers," Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat, with nationwide blackout risks not limited to Texas. read more

Some utilities have already experienced problems due to the heat. Texas' grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy as the Texas power grid faced another crisis after several plants shut unexpectedly during an early heat wave in mid-May. read more

In mid-June, Ohio-based American Electric Power Co (AEP.O) imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined. read more

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country, and the aging U.S. grid is threatening progress on renewables and EVs. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin's WEC Energy Group Inc (WEC.N) and Indiana's NiSource Inc (NI.N) to delay planned coal plant shutdowns in recent months.

BRACING FOR SUPPLY SHORTAGES
Utility operators are conserving their inventory of parts and equipment as they plan to prevent summer power outages during severe storms. Over the last several months, that means operators have been getting creative.

"We’re doing a lot more splicing, putting cables together, instead of laying new cable because we're trying to maintain our new cable for inventory when we need it," Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) (PEG.N) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

"You don’t want to deplete your inventory because you don't know when that storm is coming, but you know it's coming," Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

"If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them," Izzo said.

Germany Nuclear Power Extension keeps Isar 2, Neckarwestheim 2, and Emsland running as Olaf Scholz tackles the energy crisis, soaring gas prices, and EU winter demand, prioritizing grid stability amid the Ukraine war.

Key Points

A temporary policy keeping three German reactors online to enhance grid stability and national energy security.

✅ Extends Isar 2, Neckarwestheim 2, and Emsland operations

✅ Addresses EU energy crisis and soaring gas prices

✅ Prioritizes grid stability while coal phase-out advances

German Chancellor Olaf Scholz has ordered the country's three remaining nuclear power stations to keep operating until mid-April, signalling a nuclear U-turn as the energy crisis sparked by Russia's invasion of Ukraine hurts the economy.

Originally Germany planned to phase out all three by the end of this year, continuing its nuclear phaseout policy at the time.

Mr Scholz's order overruled the Greens in his coalition, who wanted two plants kept on standby, to be used if needed.

Nuclear power provides 6% of Germany's electricity.

The decision to phase it out was taken by former chancellor Angela Merkel after Japan's Fukushima nuclear disaster in 2011.

But gas prices have soared since Russia's invasion of Ukraine in February, which disrupted Russia's huge oil and gas exports to the EU, though some officials argue that nuclear would do little to solve the gas issue in the short term. In August Russia turned off the gas flowing to Germany via the Nord Stream 1 undersea pipeline.

After relying so heavily on Russian gas Germany is now scrambling to maintain sufficient reserves for the winter. The crisis has also prompted it to restart mothballed coal-fired power stations, with coal generating about a third of its electricity currently, though the plan is to phase out coal in the drive for green energy.

Last year Germany got 55% of its gas from Russia, but in the summer that dropped to 35% and it is declining further.

EU leaders consider how to cap gas prices
France sends Germany gas for first time amid crisis
Chancellor Scholz's third coalition partner, the liberal Free Democrats (FDP), welcomed his move to keep nuclear power as part of the mix. The three remaining nuclear plants are Isar 2, Neckarwestheim 2 and Emsland, which were ultimately shut down after the extension.

The Social Democrat (SPD) chancellor also called for ministries to present an "ambitious" law to boost energy efficiency and to put into law a phase-out of coal by 2030, aiming for a coal- and nuclear-free economy among major industrial nations.

Last week climate activist Greta Thunberg said it was a "mistake" for Germany to press on with nuclear decommissioning while resorting to coal again, intensifying debate over a nuclear option for climate goals nationwide.

HVDC-WISE Project accelerates HVDC technology integration across the European transmission system, delivering a planning toolkit to boost grid reliability, resilience, and interconnectors for renewables and offshore wind amid climate, cyber, and physical threats.

Key Points

EU-funded project delivering tools to integrate HVDC into Europe's grid, improving reliability, resilience, and security.

✅ EU Horizon Europe-backed consortium of 14 partners

✅ Toolkit to assess extreme events and grid operability

✅ Supports interconnectors, offshore wind, and renewables

A partnership of 14 leading European energy industry companies, research organizations and universities has launched a new project to identify opportunities to increase integration of HVDC technology into the European transmission system, echoing calls to invest in smarter electricity infrastructure from abroad.

The HVDC-WISE project, in which the University of Strathclyde is the UK’s only academic partner, is supported by the European Union’s Horizon Europe programme.

The project’s goal is to develop a toolkit for grid developers to evaluate the grid’s performance under extreme conditions and to plan systems, leveraging a digital grid approach that supports coordination to realise the full range of potential benefits from deep integration of HVDC technology into the European transmission system.

The project is focused on enhancing electric grid reliability and resilience while navigating the energy transition. Building and maintaining network infrastructure to move power across Europe is an urgent and complex task, and reducing losses with superconducting cables can play a role, particularly with the continuing growth of wind and solar generation. At the same time, threats to the integrity of the power system are on the rise from multiple sources, including climate, cyber, and physical hazards.

Mutual support

At a time of increasing worries about energy security and as Europe’s electricity systems decarbonise, connections between them to provide mutual support and routes to market for energy from renewables, a dynamic also highlighted in discussions of the western Canadian electricity grid in North America, become ever more important.

In modern power systems, this means making use of High Voltage Direct Current (HVDC) technology.

The earliest forms of technology have been around since the 1960s, but the impact of increasing reliance on HVDC and its ability to enhance a power system’s operability and resilience are not yet fully understood.

Professor Keith Bell, Scottish Power Professor of Future Power Systems at the University of Strathclyde, said:

As an island, HVDC is the only practical way for us to build connections to other countries’ electricity systems. We’re also making use of it within our system, with one existing and more planned Scotland-England subsea link projects connecting one part of Britain to another.

“These links allow us to maximise our use of wind energy. New links to other countries will also help us when it’s not windy and, together with assets like the 2GW substation now in service, to recover from any major disturbances that might occur.

“The system is always vulnerable to weather and things like lightning strikes or short circuits caused by high winds. As dependency on electricity increases, insights from electricity prediction specialists can inform planning as we enhance the resilience of the system.”

Dr Agusti Egea-Alvarez, Senior Lecturer at Strathclyde, said: “HVDC systems are becoming the backbone of the British and European electric power network, either interconnecting countries, or connecting offshore wind farms.

“The tools, procedures and guides that will be developed during HVDC-WISE will define the security, resilience and reliability standards of the electric network for the upcoming decades in Europe.”

Other project participants include Scottish Hydro Electric Transmission, the Supergrid Institute, the Electric Power Research Institute (EPRI) Europe, Tennet TSO, Universidad Pontificia Comillas, TU Delft, Tractebel Impact and the University of Cyprus.

Climate change

Eamonn Lannoye, Managing Director of EPRI Europe, said: “The European electricity grid is remarkably reliable by any standard. But as the climate changes and the grid becomes exposed to more extreme conditions, energy interdependence between regions intensifies and threats from external actors emerge. The new grid needs to be robust to those challenges.”

Juan Carlos Gonzalez, a senior researcher with the SuperGrid Institute which leads the project said: “The HVDC-WISE project is intended to provide planners with the tools and know-how to understand how grid development options perform in the context of changing threats and to ensure reliability.”

HVDC-WISE is supported by the European Union’s Horizon Europe programme under agreement 101075424 and by the UK Research and Innovation Horizon Europe Guarantee scheme.

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."
