Pumped Storage Hydroelectricity balances renewable energy, stabilizes the grid, and provides large-scale energy storage using reservoirs and reversible turbines, delivering flexible peak power, frequency control, and rapid response to variable wind and solar generation.

Key Points

A reversible hydro system that stores energy by pumping water uphill, then generates flexible peak power.

✅ Balances variable wind and solar with rapid ramping

✅ Stores off-peak electricity in upper reservoirs

✅ Enhances grid stability, frequency control, and reserves

The expense of hydroelectricity is moderately low, making it a serious wellspring of sustainable power. The hydro station burns-through no water, dissimilar to coal or gas plants. The commonplace expense of power from a hydro station bigger than 10 megawatts is 3 to 5 US pennies for every kilowatt hour, and Niagara Falls powerhouse upgrade projects show how modernization can further improve efficiency and reliability. With a dam and supply it is likewise an adaptable wellspring of power, since the sum delivered by the station can be shifted up or down quickly (as meager as a couple of moments) to adjust to changing energy requests.

When a hydroelectric complex is developed, the task creates no immediate waste, and it for the most part has an extensively lower yield level of ozone harming substances than photovoltaic force plants and positively petroleum product fueled energy plants, with calls to invest in hydropower highlighting these benefits. In open-circle frameworks, unadulterated pumped storage plants store water in an upper repository with no normal inflows, while pump back plants use a blend of pumped storage and regular hydroelectric plants with an upper supply that is renewed to a limited extent by common inflows from a stream or waterway.

Plants that don't utilize pumped capacity are alluded to as ordinary hydroelectric plants, and initiatives focused on repowering existing dams continue to expand clean generation; regular hydroelectric plants that have critical capacity limit might have the option to assume a comparable function in the electrical lattice as pumped capacity by conceding yield until required.

The main use for pumped capacity has customarily been to adjust baseload powerplants, however may likewise be utilized to decrease the fluctuating yield of discontinuous fuel sources, while emerging gravity energy storage concepts broaden long-duration options. Pumped capacity gives a heap now and again of high power yield and low power interest, empowering extra framework top limit.

In specific wards, power costs might be near zero or once in a while negative on events that there is more electrical age accessible than there is load accessible to retain it; despite the fact that at present this is infrequently because of wind or sunlight based force alone, expanded breeze and sun oriented age will improve the probability of such events.

All things considered, pumped capacity will turn out to be particularly significant as an equilibrium for exceptionally huge scope photovoltaic age. Increased long-distance bandwidth, including hydropower imports from Canada, joined with huge measures of energy stockpiling will be a critical piece of directing any enormous scope sending of irregular inexhaustible force sources. The high non-firm inexhaustible power entrance in certain districts supplies 40% of yearly yield, however 60% might be reached before extra capaciy is fundamental.

Pumped capacity plants can work with seawater, despite the fact that there are extra difficulties contrasted with utilizing new water. Initiated in 1966, the 240 MW Rance flowing force station in France can incompletely function as a pumped storage station. At the point when elevated tides happen at off-top hours, the turbines can be utilized to pump more seawater into the repository than the elevated tide would have normally gotten. It is the main enormous scope power plant of its sort.

Alongside energy mechanism, pumped capacity frameworks help control electrical organization recurrence and give save age. Warm plants are substantially less ready to react to abrupt changes in electrical interest, and can see higher thermal PLF during periods of reduced hydro generation, conceivably causing recurrence and voltage precariousness.

Pumped storage plants, as other hydroelectric plants, including new BC generating stations, can react to stack changes in practically no time. Pumped capacity hydroelectricity permits energy from discontinuous sources, (for example, sunlight based, wind) and different renewables, or abundance power from consistent base-load sources, (for example, coal or atomic) to be put something aside for times of more popularity.

The repositories utilized with siphoned capacity are tiny when contrasted with ordinary hydroelectric dams of comparable force limit, and creating periods are regularly not exactly a large portion of a day. This technique produces power to gracefully high top requests by moving water between repositories at various heights.

Now and again of low electrical interest, the abundance age limit is utilized to pump water into the higher store. At the point when the interest gets more noteworthy, water is delivered once more into the lower repository through a turbine. Pumped capacity plans at present give the most monetarily significant methods for enormous scope matrix energy stockpiling and improve the every day limit factor of the age framework. Pumped capacity isn't a fuel source, and shows up as a negative number in postings.

Ontario Utilities Hurricane Irma Aid mobilizes Hydro One and Toronto Hydro crews to Tampa Bay, Florida, restoring power outages with bucket trucks, lineworkers, and mutual aid alongside Florida Power & Light after catastrophic damage.

Key Points

Mutual aid sending Hydro One and Toronto Hydro crews to Florida to restore power after Hurricane Irma.

✅ 205 workers, 52 bucket trucks, 30 support vehicles deployed

✅ Crews assist Tampa Bay under FPL mutual aid agreements

✅ Weeks-long restoration projected after catastrophic outages

Hurricane Irma has left nearly 7 million homes in the southern United States without power and two Ontario hydro utility companies are sending teams to help out as part of Canadian power crews responding to the disaster.

Toronto Hydro is sending 30 staffers to aid in the restoration efforts in Tampa Bay while Hydro One said Sunday night that it would send 175 employees after receiving a request from Florida Power and Light.

“I've been on other storms down in the states and they are pretty happy to see you especially when they find out you're from Canada,” Dean Edwards, one of the Hydro One employees heading to Florida, told CTV Toronto.

Most of the employees are expected to cross the border on Monday afternoon and arrive Wednesday.

Among the crews, Hydro One says it will send 150 lines and forestry staff, as well as 25 supporting resources, including mechanics, to help. Crews will bring 52 bucket trucks to Florida, as well as 30 other vehicles, reflecting their Ontario storm restoration experience with large-scale deployments, and pieces of equipment to transport and replace poles.

Hurricane Irma has claimed at least 45 lives in the Caribbean and United States thus far. Officials estimate that restoring power to Florida will take weeks to bring power back online.

“I’m sure a lot of people wish they could go down and help, fortunately our job is geared towards that so we're going to go down there to do our best and represent Canada,” said Blair Clarke, who’s making his first trip over the border.

Hydro One has reciprocal arrangements with other North American utilities to help with significant power outages, and its employees have provided COVID-19 support in Ontario as part of broader emergency efforts. All the costs are covered by the utility receiving the help.

In the past, the utility has sent crews to Massachusetts, Michigan, Florida, Ohio, Vermont, Washington, DC, and the Carolinas, while Sudbury Hydro crews have worked to reconnect service after storms at home as well. In 2012, 225 Hydro One employees travelled to Long Island, N.Y., to help out with Hurricane Sandy.

“This is what our guys and gals do,” Natalie Poole-Moffat, vice president of Corporate Affairs for Hydro One, told CP24. “They’re fabulous at it and we’re really proud of the work they do.”

BWI Power Outage caused flight delays, cancellations, and diversions after a downed power line near Baltimore/Washington International. BGE crews responded as terminal operations, security screening, and boarding slowed, exposing infrastructure gaps and backup power needs.

Key Points

A downed power line disrupted BWI, causing delays, diversions, and slowed operations after power was restored by noon.

✅ Downed power line near airport spurred terminal-wide disruptions

✅ 150+ delays, dozens of cancellations; diversions to nearby airports

✅ BGE response, backup power gaps highlight infrastructure resilience

On the morning of March 3, 2025, a major power outage at Baltimore/Washington International Thurgood Marshall Airport (BWI) caused significant disruptions to air travel, much like the London morning outage that upended routines, affecting both departing and incoming flights. The outage, which began around 7:40 a.m., was caused by a downed power line near the airport, according to officials from Baltimore Gas and Electric Company. Although power was restored by noon, the effects were felt for several hours, resulting in flight delays, diversions, and a temporary disruption to airport operations.

Flight Disruptions and Delays

The outage severely impacted operations at BWI, with more than 150 flights delayed and dozens more canceled. The airport, which serves as a major hub for both domestic and international travel, was thrown into chaos, similar to the Atlanta airport blackout that snarled operations, as power outages affected various critical areas, including parts of the main terminal and an adjacent parking garage. The downed power line created a ripple effect throughout the airport’s operations, delaying not only the check-in and security screening processes but also the boarding of flights. In addition to the delays, some inbound flights had to be diverted to nearby airports, further complicating an already strained travel schedule.

With the disruption affecting vital functions of the airport, passengers were advised to stay in close contact with their airlines for updated flight statuses and to prepare for longer-than-usual wait times.

Impact on Passengers

As power began to return to different parts of the terminal, airport officials reported that airlines were improvising solutions to continue the deplaning process, such as using air stairs to help passengers exit planes that were grounded due to the power outage, a reminder of how transit networks can stall during grid failures, as seen with the London Underground outage that frustrated commuters. This created further delays for passengers attempting to leave the airport or transfer to connecting flights.

Many passengers, who were left stranded in the terminal, faced long lines at ticket counters, security checkpoints, and concessions as the airport worked to recover from the loss of power, a situation mirrored during the North Seattle outage that affected thousands. The situation was compounded by the fact that while power was restored by midday, the airport still struggled to return to full operational capacity, creating significant inconvenience for travelers.

Power Restoration and Continued Delays

By around noon, officials confirmed that power had been fully restored across the main terminal. However, the full return to normalcy was far from immediate. Airport staff continued to work on clearing backlogs and assisting passengers, but the effects of the outage lingered throughout the day. Passengers were warned to expect continued delays at ticket counters, security lines, and concessions as the airport caught up with the disruption caused by the morning’s power outage.

For many travelers, the experience was a reminder of how dependent airports and airlines are on uninterrupted power to function smoothly. The disruption to BWI serves as a case study in the potential vulnerabilities of critical infrastructure that is not immune to the effects of power failure, including weather-driven events like the windstorm outages that can sever lines. Moreover, it highlights the difficulties of recovering from such incidents while managing the expectations of a large number of stranded passengers.

Investigations into the Cause of the Outage

As of the latest reports, Baltimore Gas and Electric Company (BGE) crews were still investigating the cause of the power line failure, including weather-related factors seen when strong winds in the Miami Valley knocked out power. While no definitive cause had been provided by early afternoon, BGE spokesperson Stephanie Weaver confirmed that the company was working diligently to restore service. She noted that the downed line had caused widespread disruptions to electrical service in the area, which were exacerbated by the airport’s significant reliance on a stable power supply.

BWI officials remained in close contact with BGE to monitor the situation and ensure that necessary precautions were taken to prevent further disruptions. With power largely restored by midday, focus turned to the logistical challenges of clearing the resulting delays and assisting passengers in resuming their travel plans.

Response from the Airport and Airlines

In response to the power outage, BWI officials encouraged travelers to remain patient, a familiar message during prolonged events like Houston's extended outage in recent months, and continue checking their flight statuses. Although flight tracking websites and social media posts provided timely updates, passengers were urged to expect long delays throughout the day as the airport struggled to return to full capacity.

Airlines, for their part, worked swiftly to accommodate affected passengers, although the situation created a ripple effect across the airport's operations. With delayed flights and diverted planes, air traffic control and ground crews had to adjust flight schedules accordingly, resulting in even more congestion at the airport. Airlines coordinated with the airport to prioritize urgent cases, and some flights were re-routed to other nearby airports to mitigate the strain on the terminal.

Long-Term Effects on Airport Infrastructure

This incident underscores the importance of maintaining resilient infrastructure at key transportation hubs like BWI. Airports are vital nodes in the air travel network, and any disruption, whether from power failure or other factors, can have far-reaching consequences on both domestic and international travel. Experts suggest that BWI and other major airports should consider implementing backup power systems and other safeguards to ensure that they can continue to function smoothly during unforeseen disruptions.

While BWI officials were able to resolve the situation relatively quickly, the power outage left many passengers frustrated and inconvenienced. This incident serves as a reminder of the need for airports and utilities to have robust contingency plans in place to handle emergencies and prevent delays from spiraling into more significant disruptions.

The power outage at Baltimore/Washington International Airport highlights the vulnerability of critical infrastructure to power failures and the cascading effects such disruptions can have on travel. Although power was restored by noon, the delays, diversions, and logistical challenges faced by passengers underscore the need for greater resilience in airport operations. With travel back on track, BWI and other airports will likely revisit their contingency plans to ensure that they are better prepared for future incidents that could affect air travel.

Peterborough Distribution Inc. Sale to Hydro One delivers a $105 million deal pending Ontario Energy Board approval, a 1% distribution rate cut, five-year rate freeze, job protections, and a new operations centre and fleet facility.

Key Points

A $105M acquisition of PDI by Hydro One, with OEB review, rate freeze, job protections, and a new operations centre.

✅ $105 million purchase; Ontario Energy Board approval required

✅ 1% distribution rate cut and a five-year rate freeze

✅ New operations centre; PDI employees offered roles at Hydro One

The City of Peterborough said Wednesday it has agreed to sell Peterborough Distribution Inc. to Hydro One for $105 million, amid a period when Hydro One shares fell after leadership changes.

The deal requires approval from the Ontario Energy Board before it can proceed.

According to the city, the deal includes a one per cent distribution rate reduction and a five-year freeze in distribution rates for customers, plus:

• A second five-year period with distribution rate increases limited to inflation and an earnings sharing mechanism to offset rates in year 11 and onward
• Protections for PDI employees with employees receiving employment offers to move to Hydro One
• A sale price of $105 million
• An agreement to develop a regional operations centre and new fleet maintenance facility in Peterborough

“Hydro One was unique in its ability to offer new investment and job creation in our community through the addition of a new operations centre to serve customers throughout the broader region,” Mayor Daryl Bennett said.

“We’re surrounded by Hydro One territory — in fact, we already have Hydro One customers within the City of Peterborough and new subdivisions will be in Hydro One territory. Hydro One will be able to create efficiencies by better utilizing its existing infrastructure, benefiting customers and supporting growth.”

The sale comes after months of negotiations amid investor concerns about Hydro One’s uncertainties. At one point, it looked like the sale wouldn’t go through, after it was announced that Hydro One had walked away from the bargaining table.

City council approved the sale of PDI in December 2016, despite a strong public opposition and debate over proposals to make hydro public again among some parties.

Elsewhere in Canada, political decisions around utilities have also sparked debate, as seen when Manitoba Hydro faced controversy over policy shifts.

✅ Joint pledge by AWEA, SEIA, NHA, and ESA for a cleaner grid

✅ Focus on resilience, efficiency, affordability, and fair competition

✅ Storage enables flexibility to integrate variable renewables

Within a decade, more than half of the electricity generated in the U.S. will come from clean, renewable resources, with analyses indicating that wind and solar could meet 80% of U.S. electricity demand, supported by energy storage, according to a joint commitment today from the American wind, solar, hydropower, and energy storage industries. The American Wind Energy Association (AWEA), Solar Energy Industries Association (SEIA), National Hydropower Association (NHA), and Energy Storage Association (ESA) have agreed to actively collaborate across their industry segments to achieve this target. 

The four industries have released a set of joint advocacy principles that will enable them to realize this bold vision of a majority renewables grid. Along with increased collaboration, these shared principles include building a more resilient, efficient, sustainable, and affordable grid; achieving carbon reductions; and advancing greater competition through electricity market reforms and fair market rules. Each of these areas is critical to attaining the shared vision for 2030.  

The leaders of the four industry associations gathered to announce the shared vision, aligned with a broader 100% renewables pathway pursued nationwide, during the first CLEANPOWER annual conference for businesses across the renewable and clean energy spectrum. 

American Wind Energy Association 

"This collaborative promise sets the stage to deliver on the American electric grid of the future powered by wind, solar, hydropower, and storage," said Tom Kiernan, CEO of the American Wind Energy Association. "Market opportunities for projects that include a mix of technologies have opened up that didn't exist even a few years ago. And demand is growing for integrated renewable energy options. Individually and cooperatively, these sectors will continue growing to meet that demand and create hundreds of thousands of new jobs to strengthen economies from coast to coast, building a better, cleaner tomorrow. In the face of significant challenges the country is currently facing across pandemic response, economic, climate and social injustice problems, we are prepared to help lead toward a healthier and more equitable future."

Solar Energy Industries Association

"These principles are just another step toward realizing our vision for a Solar+ Decade," said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association. "In the face of this dreadful pandemic, our nation must chart a path forward that puts a premium on innovation, jobs recovery and a smarter approach to energy generation, reflecting expected solar and storage growth across the market. The right policies will make a growing American economy fueled by clean energy a reality for all Americans."

National Hydropower Association 

"The path towards an affordable, reliable, carbon-free electricity grid, supported by an ongoing grid overhaul for renewables, starts by harnessing the immense potential of hydropower, wind, solar and storage to work together," said Malcolm Woolf, President and CEO of the National Hydropower Association. "Today, hydropower and pumped storage are force multipliers that provide the grid with the flexibility needed to integrate other renewables onto the grid. By adding new generation onto existing non-powered dams and developing 15 GW of new pumped storage hydropower capacity, we can help accelerate the development of a clean energy electricity grid."

Energy Storage Association 

"We are pleased to join forces with our clean energy friends to substantially reduce carbon emissions by 2030, guided by practical decarbonization strategies, building a more resilient, efficient, sustainable, and affordable grid for generations to come," said ESA CEO Kelly Speakes-Backman. "A majority of generation supplied by renewable energy represents a significant change in the way we operate the grid, and the storage industry is a fundamental asset to provide the flexibility that a more modern, decarbonized grid will require. We look forward to actively collaborating with our colleagues to make this vision a reality by 2030."

FERC Transmission Planning Overhaul streamlines interregional grid buildouts, enabling high-voltage lines, renewable integration, and grid reliability to scale, cutting fossil reliance while boosting decarbonization, climate resilience, and affordability across regions facing demand and extreme weather.

Key Points

Federal rule updating interregional grid planning to integrate renewables, share costs, and improve reliability.

✅ Accelerates high-voltage, interregional lines for renewable transfer

✅ Optimizes transmission planning and cost allocation frameworks

✅ Boosts grid reliability, resilience, and emissions reductions

The US took a significant step towards a cleaner energy future on May 13th, 2024. The Federal Energy Regulatory Commission (FERC) approved the first major update to the country's electric transmission policy in over a decade, while congressional Democrats continue to push for action on aggregated DERs within FERC's remit today. This overhaul aims to streamline the process of building new power lines, specifically those that connect different regions. This improved connectivity is crucial for integrating more renewable energy sources like wind and solar into the national grid.

The current system faces challenges in handling the influx of renewables, and the aging U.S. grid amplifies those hurdles today. Renewable energy sources are variable by nature – the sun doesn't always shine, and the wind doesn't always blow. Traditionally, power grids have relied on constantly running power plants, like coal or natural gas, to meet electricity demands. These plants can be easily adjusted to produce more or less power as needed. However, renewable energy sources require a different approach.

The new FERC policy focuses on building more interregional transmission lines. These high-voltage power lines would allow electricity generated in regions with abundant solar or wind power, and even enable imports of green power from Canada in certain corridors, to be transmitted to areas with lower renewable energy resources. For example, solar energy produced in sunny states like California could be delivered to meet peak demand on the East Coast during hot summer days.

This improved connectivity offers several advantages. Firstly, it allows for a more efficient use of renewable resources. Secondly, it reduces the need for fossil fuel-based power plants, leading to cleaner air and lower greenhouse gas emissions. Finally, a more robust grid is better equipped to handle extreme weather events, which are becoming increasingly common due to climate change, and while Biden's climate law shows mixed results on decarbonization, stronger transmission supports resilience.

The need for an upgrade is undeniable. The Biden administration has set ambitious goals for decarbonizing the power sector by 2035, including proposals for a clean electricity standard as a pathway to those targets. A study by the US Department of Energy estimates that achieving this target will require more than doubling the country's regional transmission capacity and increasing interregional capacity by more than fivefold. The aging US grid is already struggling to keep up with current demands, and without significant improvements, it could face reliability issues in the future.

The FERC's decision has been met with praise from environmental groups and renewable energy companies. They see it as a critical step towards achieving a clean energy future. However, some stakeholders, including investor-owned utilities, have expressed concerns about the potential costs associated with building new transmission lines, citing persistent barriers to development identified in recent Senate testimony. Finding the right balance between efficiency, affordability, and environmental responsibility will be key to the success of this initiative.

The road ahead won't be easy. Building new power lines is a complex process that can face opposition from local communities, and broader disputes over electricity pricing changes often complicate planning and approvals. However, the potential benefits of a modernized grid are significant. By investing in this overhaul, the US is taking a crucial step towards a more reliable, sustainable, and cleaner energy future.
