Direct Energy, one of North America's largest energy and energy related services companies, is pleased to announce the participation of Woodbine Entertainment Group (WEG) in Direct Energy's 25MW commitment to the Ontario Power Authority's (OPA) Demand Response program (DR3).
The DR3 program is a contractual peak load shedding agreement between the OPA and energy aggregators with the objective of reducing electricity usage when the Ontario electricity grid is overly stressed.
"Direct Energy is committed to being a leader in energy conservation initiatives. Promoting energy conservation in the home and office is a core element of Direct Energy's business," said Bob Huggard, President, Direct Energy Home and Business Services. "The successful execution of programs such as this is essential if Ontario is to succeed in creating an environment where the lights will always be on."
Direct Energy, in partnership with its clients, has committed to reduce electricity demand by 25MW when requested by the OPA. Assuming an average Ontario household draws 2.5 kW from the electricity grid, during the summer's peak electricity usage period, Direct Energy's 25MW reduction commitment ensures 10,000 homes will have consistent electricity supply.
The OPA's DR3 program, one of the most competitive programs in North America, compensates organizations for reducing electricity use during periods of peak demand. Participating organizations are compensated in two ways: for being available to shed electricity during their selected hours and for reducing their electricity when requested. Direct Energy estimates that the revenue potential for an organization that commits to shedding 200 kW, from one or more of its facilities, over five years is up to $200,000 in addition to their electricity savings.
"Woodbine Entertainment Group is first out of the starting gate when it comes to adopting measures that enable us to be more energy efficient. We are excited that Direct Energy identified another opportunity for us to do even more," stated Nick Eaves, President and COO of WEG. Over the last three years, Direct Energy has worked with WEG to update much of its infrastructure to more energy efficient standards including retrofitting their boiler plant, installing power-saving lighting controls and updating their building automation system.
The OPA DR3 program is best suited for forward-looking, environmentally conscious organizations, such as WEG, who have a minimum peak demand of 1MW in one or multiple facilities. By volunteering to reduce load on the grid as part of DR3, participating organizations ensure that home owners and small businesses experience uninterrupted power delivery during peak hours.
"Involving our business customers in the DR3 program is just the tip of the iceberg in a complete energy management strategy. Revenue earned from reduced energy use and enrollment in the DR3 program can easily be reinvested into energy conservation and demand management initiatives," noted Michael Flores, Vice President, Demand Response Business, North America.

25% Tariff on Canadian Imports threatens New York energy markets, disrupting hydroelectric power and natural gas supply chains, raising electricity prices, increasing gas costs, and intensifying trade tensions, policy uncertainty, and cross-border logistics risks.
Key Points
A U.S. policy imposing 25% duties on Canadian goods, risking higher New York electricity and natural gas costs.
✅ Hydroelectric and gas imports face costlier cross-border flows
✅ Higher utility bills for NY households and businesses
✅ Supply chain volatility and policy uncertainty increase
President Donald Trump announced the imposition of a 25% tariff on all imports from Canada, citing concerns over drug trafficking and illegal immigration. This decision has raised significant concerns among experts and residents in New York, who warn that the tariff could lead to increased electricity and gas prices in the state.
Impact on New York's Energy Sector
New York relies heavily on energy imports from Canada, particularly electricity and natural gas. Canada is a major supplier of hydroelectric power to the northeastern United States, including New York, with its electricity exports at risk amid trade tensions. The imposition of a 25% tariff on Canadian goods could disrupt this supply chain, leading to higher energy costs for consumers and businesses in New York. Justin Wilcox, an energy analyst, stated, "If the tariff is implemented, it could lead to increased costs for electricity and gas, affecting both consumers and businesses."
Potential Economic Consequences
The increased energy costs could have broader economic implications for New York, and some experts advise against cutting Quebec's exports to avoid exacerbating market volatility. Higher electricity and gas prices may lead to increased operational costs for businesses, potentially resulting in higher prices for goods and services, while tariff threats have boosted support for Canadian energy projects that could reshape regional supply. This could exacerbate the cost-of-living challenges faced by residents and strain the state's economy.
Political and Diplomatic Reactions
The tariff has also sparked political and diplomatic reactions, including threats to cut U.S. electricity exports from Ontario that raised tensions. New York Governor Kathy Hochul expressed concern over the potential economic impact, stating, "We are closely monitoring the situation and are prepared to take necessary actions to protect New York's economy." Additionally, Canadian officials have expressed their disapproval of the tariff, and Ontario Premier Doug Ford's Washington meeting underscored ongoing discussions, emphasizing the importance of the trade relationship between the two countries.
Historical Context
This development is part of a broader pattern of trade tensions between the United States and its neighbors. In 2018, the U.S. imposed tariffs on Canadian steel and aluminum, leading to retaliatory measures from Canada. The current situation underscores the ongoing challenges in international trade relations, where a recent tariff threat delayed Quebec's green energy bill and highlighted the potential domestic impacts of such policies.
The imposition of a 25% tariff on Canadian imports by President Trump has raised significant concerns in New York regarding potential increases in electricity and gas prices. Experts warn that this could lead to higher costs for consumers and businesses, with broader economic implications for the state. As the situation develops, it will be crucial to monitor the responses from both state and federal officials, as well as how Canadians support tariffs on energy and minerals may influence policy, and the potential for diplomatic negotiations to address these trade tensions.
PJM and MISO Electricity-Market Reforms promise consumer savings by enabling renewables, wind, solar, and storage participation in wholesale markets, enhancing grid flexibility, reliability services, and real-time pricing across the Midwest, Great Lakes, and Mid-Atlantic.
Key Points
Market rule updates enabling renewables and storage, improving reliability and lowering consumer costs.
✅ Removes barriers to renewables, storage, demand response
✅ Improves intermarket links and real-time price signals
✅ Rewards flexible resources and reliability services
Electricity-market reforms to enable more renewables generation and storage in the Midwest, Great Lakes, and Mid-Atlantic could save consumers in the US and Canada more than $6.9 billion a year, according to a new report.
The findings may have major implications for consumer groups, large industrial companies, businesses, and homeowners in those regions, said the Wind-Solar Alliance, (WSA), which commissioned the Customer Focused and Clean report.
The WSA is a non-profit organisation supporting the growth of renewables. American Wind Energy Association CEO Tom Kiernan is listed as WSA secretary, amid ongoing debates about the US wind market today.
"Consumers are looking for clean energy, affordable and reliable energy that will keep their monthly electricity bills low," said Kristin Munsch, president of the Board of the Consumer Advocates of the PJM States, which represents over 65 million consumers in 13 states.
"There is great potential to achieve those goals with the cost-effective integration of wind, solar and battery storage plants into our wholesale power markets."
The report found the average residential customer in the PJM and Midcontinent Independent System Operator (MISO) regions, covering 29 US states and the Canadian province of Manitoba, could each save up to $48 a year as lower wholesale electricity prices materialize with significantly more wind, solar and storage on the grid.
The average annual home electricity, for example in New Jersey, in the PJM region, was just over $106 in 2018, according to the US Energy Information Administration.
The latest report quantifies the findings of a previous one for the WSA, published in November 2018, which found that outdated wholesale market rules in the US were preventing full participation by renewable energy, including wind power.
Outdated rules
"The existing wholesale power market rules were largely developed for slower-to-react conventional generators, such as coal and nuclear plants," said Michael Milligan, president of Milligan Grid Solutions and co-author of the new report.
"This report demonstrates the benefits of updating the rules to better accommodate the characteristics and potential contributions of wind and solar and other newer sources of low-cost generation."
With more renewables generation on the grid, customers would benefit the most from increasing power-system flexibility through market structures, the new report concluded. It called for the removal of artificial barriers preventing renewables, storage and demand response from participating in markets.
The report also advocated improving the connections between markets, thereby lowering transaction costs of imports and exports between neighbouring systems.
"There are currently artificial barriers that are preventing the full participation of renewables, storage and other new technologies in the PJM and MISO markets," said Michael Goggin, vice president of Grid Strategies and co-author of the report.
"Providing consumers with a real-time price signal that allows them to adjust their demand, rewarding flexible resources for their capabilities through improved market design, and allowing renewable and storage resources to participate in reliability-services markets would yield the greatest consumer benefits," he said.
PJM and MISO, which incorporate some of the windiest areas of the country, are currently reviewing their market designs as part of a broader grid overhaul underway.
Muskrat Falls Financing Restructuring redirects megadam benefits to ratepayers, stabilizes electricity rates, and overhauls federal provincial loan guarantees for the hydro project, addressing cost overruns flagged by the Public Utilities Board in Newfoundland and Labrador.
Key Points
A revised funding model shifting benefits to ratepayers to curb rate hikes linked to Muskrat Falls cost overruns.
✅ Shields ratepayers from megadam cost overruns
✅ Revises federal provincial loan guarantees
✅ Targets stable electricity rates by 2021 and beyond
Ottawa and Newfoundland and Labrador say they will rewrite the financial structure of the Muskrat Falls hydro project to shield ratepayers from paying for the megadam's cost overruns.
Federal Natural Resources Minister Seamus O'Regan and Premier Dwight Ball announced Monday that their two governments would scrap the financial structure agreed upon in past federal-provincial loan agreements, moving to a model that redirects benefits, such as a lump sum credit, to ratepayers.
Both politicians called the announcement, which was light on dollar figures, a major milestone in easing residents' fears that electricity rates will spike sharply, as seen with Nova Scotia's debated 14% hike, when the over-budget dam comes fully online next year. "We are in a far better place today thanks to this comprehensive plan," Ball said.
Ball has said the issue of electricity rates is a top priority for his government, and he has pledged to keep rates near existing levels, but rate mitigation talks with Ottawa have dragged on since April.
A report by the province's Public Utilities Board released Friday forecast an "unprecedented" 75 per cent increase in average domestic rates for island residents in 2021, while Nova Scotia's regulator approved a 14% hike, and reported concerns from industrial customers about their ability to remain competitive.
Costs of the Muskrat Falls megadam on Labrador's Lower Churchill River have ballooned to more than $12.7 billion since the project was approved in 2012, according to the latest estimate of Crown corporation Nalcor Energy.
The dam is set to produce more power than the province can sell. Its existing financial structure would have left electricity ratepayers paying for Muskrat Falls to make up the difference starting in 2021, an issue both governments said Monday has been resolved with the relaunch of financing talks.
"Essentially, you won't pay this on your monthly light bills," Ball said.
But details of how the project will meet financing requirements in coming decades to make up the gap in funds are still to be worked out.
Both Ball and O'Regan criticized previous governments for sanctioning the poorly planned development and again pledged their commitment to easing the burden on residents.
"We promised we would be there to help, and we will be," O'Regan said before announcing a "relaunch" of negotiations around the project's financial structure.
He did not say how much the new setup might cost the federal government, despite earlier federal funding commitments, stressing that the new focus will be on the project's long-term sustainability. "There's no single piece of policy ... that can resolve such a large and complicated mess," O'Regan said.
The two governments also said they will work towards electrifying federal buildings to reduce an anticipated power surplus in the province.
In the short term, the federal government said it would allow for "flexibility" in upcoming cash requirements related to debt servicing, allowing deferral of payments if necessary.
Ball said that flexibility was built in to ensure the plan would still be applicable if costs continue to rise before Muskrat Falls is commissioned.
Political opponents criticized Monday's plan as lacking detail.
"What I heard talked about was an agreement that in the future, there's going to be an agreement," said Progressive Conservative Leader Ches Crosbie. "This was an occasion to reassure people that there's a plan in place to make life here affordable, and I didn't see that happen today."
Others addressed the lingering questions about the project's final cost.
Nalcor's latest financial update has remained unchanged since 2017, though the Muskrat Falls project has seen additional delays related to staffing and software issues.
Dennis Browne, the province's consumer advocate, said the switch to a cost of service model is a significant move that will benefit ratepayers, but he said it's impossible to truly restructure the project while it's a work in progress. "We need to know what the figures are, and we don't have them," he said.
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
Ireland electricity support measures include PSO levy rebates, RESS 2 renewables, CRU-directed EirGrid backup capacity, and grid investment for the Celtic Interconnector, cutting bills, boosting security of supply, and reducing reliance on imported fossil fuels.
Key Points
Government steps to cut bills and secure supply via PSO rebates, RESS 2 renewables, backup power, and grid upgrades.
✅ PSO levy rebates lower domestic electricity bills.
✅ RESS 2 adds wind, solar, and hydro to the grid.
✅ EirGrid to procure temporary backup capacity for winter peaks.
Ireland's Cabinet has approved a package of measures to help mitigate the rising cost of rising electricity bills, as Irish provider price increases continue to pressure consumers, and to ensure secure supplies to electricity for households and business across Ireland over the coming years.
The package of measures includes changes to the Public Service Obligation (PSO) levy (beyond those announced earlier in the year), which align with emerging EU plans for more fixed-price electricity contracts to improve price stability. The changes will result in rebates, and thus savings, for domestic electricity bills over the course of the next PSO year beginning in October. This further reduction in the PSO levy occurs because of a fall in the relative cost of renewable energy, compared to fossil fuel generation.
The Government has also approved the final results of the second onshore Renewable Electricity Support Scheme (RESS 2) auction, echoing how Ontario's electricity auctions have aimed to lower costs for consumers. This will bring significantly more indigenous wind, solar and hydro-electric energy onto the National Grid. This, in turn, will reduce our reliance on increasingly expensive imported fossil fuels, as the UK explores ending the gas-electricity price link to curb bills.
The package also includes Government approval for the provision of funding for back-up generation capacity, to address risks to security of electricity supply over the coming winters, similar to the UK's forthcoming energy security law approach in this area. The Commission for the Regulation of Utilities (CRU), which has statutory responsibility for security of supply, has directed EirGrid to procure additional temporary emergency generation capacity (for the winters of 2023/2024 to 2025/2026). This will ultimately provide flexible and temporary back-up capacity, to safeguard secure supplies of electricity for households and businesses as we deploy longer-term generation capacity.
Today’s measures also see an increased borrowing limit (€3 billion) for EirGrid – to strengthen our National Grid as part of 'Shaping Our Electricity Future' and to deliver the Celtic (Ireland-France) Interconnector, amid wider European moves to revamp the electricity market that could enhance cross-border resilience. An increased borrowing limit (€650 million) for Bord na Móna will drive greater deployment of indigenous renewable energy across the Midlands and beyond – as part of its 'Brown to Green' strategy, while measures like the UK's household energy price cap illustrate the scale of consumer support elsewhere.
