N.L., Ottawa agree to shield ratepayers from Muskrat Falls cost overruns

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.

Ukraine Power Grid Attacks disrupt critical infrastructure as missiles and drones strike power plants, substations, and lines, causing blackouts. Emergency repairs, international aid, generators, and renewables bolster resilience and keep hospitals and water running.

Key Points

Russian strikes on Ukraine's power infrastructure cause blackouts; repairs and aid sustain hospitals and water.

✅ Missile and drone strikes target plants, substations, and lines.

✅ Crews restore power under fire; air defenses protect sites.

✅ Allies supply equipment, generators, and grid repair expertise.

Ukraine is facing an ongoing battle to maintain its electrical grid in the wake of relentless Russian attacks targeting power plants and energy infrastructure. These attacks, which have intensified in the last year, are part of Russia's broader strategy to weaken Ukraine's ability to function amid the ongoing war. Power plants, substations, and energy lines have become prime targets, with Russian forces using missiles and drones to destroy critical infrastructure, as western Ukraine power outages have shown, leaving millions of Ukrainians without electricity and heating during harsh winters.

The Ukrainian government and energy companies are working tirelessly to repair the damage and prevent total blackouts, while also trying to ensure that civilians have access to vital services like hospitals and water supplies. Ukraine has received support from international allies in the form of technical assistance and equipment to help strengthen its power grid, and electricity reserve updates suggest outages can be avoided if no new strikes occur. However, the ongoing nature of the attacks and the complexity of repairing such extensive damage make the situation extraordinarily difficult.

Despite these challenges, Ukraine's resilience is evident, even as winter pressures on the battlefront intensify operations. Energy workers are often working under dangerous conditions, risking their lives to restore power and prevent further devastation. The Ukrainian government has prioritized the protection of energy infrastructure, with military forces being deployed to safeguard workers and critical assets.

Meanwhile, the international community continues to support Ukraine through financial and technical aid, though some U.S. support programs have ended recently, as well as providing temporary power solutions, like generators, to keep essential services running. Some countries have even sent specialized equipment to help repair damaged power lines and energy plants more quickly.

The humanitarian consequences of these attacks are severe, as access to electricity means more than just light—it's crucial for heating, cooking, and powering medical equipment. With winter temperatures often dropping below freezing, plans to keep the lights on are vital to protect vulnerable communities, and the lack of reliable energy has put many lives at risk.

In response to the ongoing crisis, Ukraine has also focused on enhancing its energy independence, seeking alternatives to Russian-supplied energy. This includes exploring renewable energy sources, such as solar and wind power, and new energy solutions adopted by communities to overcome winter blackouts, which could help reduce reliance on traditional energy grids and provide more resilient options in the future.

The battle for energy infrastructure in Ukraine illustrates the broader struggle of the country to maintain its sovereignty and independence in the face of external aggression. The destruction of power plants is not only a military tactic but also a psychological one—meant to instill fear and disrupt daily life. However, the unwavering spirit of the Ukrainian people, alongside international support, including Ukraine's aid to Spain during blackouts as one example, continues to ensure that the fight to "keep the lights on" is far from over.

As Ukraine works tirelessly to repair its energy grid, it also faces the challenge of preparing for the long-term impact of these attacks. The ongoing war has highlighted the importance of securing energy infrastructure in modern conflicts, and the world is watching as Ukraine's resilience in this area could serve as a model for other nations facing similar threats.

Ukraine’s energy struggle is far from over, but its determination to keep the lights on remains a beacon of hope and defiance in the face of ongoing adversity.

Commercial Electric Tariffs explain utility rate structures, peak demand charges, kWh vs kW pricing, time-of-use periods, voltage, delivery, capacity ratchets, and riders, guiding facility managers in tariff analysis for accurate energy savings.

Key Points

Commercial electric tariffs define utility pricing for energy, demand, delivery, time-of-use periods, riders, and ratchet charges.

✅ Separate kWh charges from kW peak demand fees.

✅ Verify time-of-use windows and demand interval length.

✅ Review riders, capacity ratchets, and minimum demand clauses.

Especially during these tough economic times, as major changes to electric bills are debated in some states, facility executives who don’t understand how their power is priced have been disappointed when their energy projects failed to produce expected dollar savings. Here’s how not to be one of them.

Your electric rate is spelled out in a document called a “tariff” that can be downloaded from your utility’s web page. A tariff should clearly spell out the costs for each component that is part of your rate, reflecting cost allocation practices in your region. Don’t be surprised to learn that it contains a bunch of them. Unlike residential electric rates, commercial electric bills are not based solely on the quantity of kilowatt-hours (kWh) consumed in a billing period (in the United States, that’s a month). Instead, different rates may apply to how your power is supplied, how it is delivered via electricity delivery charges, when it was consumed, its voltage, how fast it was used (in kW), and other factors.

If a tariff’s lingo and word structure are too opaque, spend some time with a utility account rep to translate it. Many state utility commissions also have customer advocates that may assist as they explore new utility rate designs that affect customers. Alternatively, for a fee, facility managers can privately chat with an energy consultant.

Common mistakes

Many facility managers try to estimate savings based on an averaged electric rate, i.e., annual electric spend divided by annual kWh. However, in markets where electricity demand is flat, such a number may obscure the fastest rising cost component: monthly peak demand charges, measured in dollars per kW (or kilo-volt-amperes, kVA).

This charge is like a monthly speeding ticket, based solely on the highest speed you drove during that time. In some areas, peak demand charges now account for 30 to 60 percent of a facility’s annual electric spend. When projecting energy cost savings, failing to separately account for kW peak demand and kWh consumption may result in erroneous results, and a lot of questions from the C-suite.

How peak demand charges are calculated varies among utilities. Some base it on the highest average speed of use across one hour in a month, while others may use the highest average speed during a 15- or 30-minute period. Others may average several of the highest speeds within a defined time period (for example, 8 a.m. to 6 p.m. on weekdays). It is whatever your tariff says it is.

Because some power-consuming (or producing) devices, including those tied to smart home electricity networks, vary in their operation or abilities, they may save money on a few — but not all — of those rate components. If an equipment vendor calculates savings from its product by using an average electric rate, take pause. Tell the vendor to return after the proposal has been redone using tariff-based numbers.

When a vendor is the only person calculating potential savings from using a product, there’s also a built-in conflict of interest: The person profiting from an equipment sale should not also be the one calculating its expected financial return. Before signing any energy project contracts, it’s essential that someone independent of the deal reviews projected savings. That person (typically an energy or engineering consultant) should be quite familiar with your facility’s electric tariff, including any special provisions, riders, discounts, etc., that may pertain. When this doesn’t happen, savings often don’t occur as planned. 

For example, some utilities add another form of demand charge, based on the highest kW in a year. It has various names: capacity, contract demand, or the generic term “ratchet charge.” Some utilities also have a minimum ratchet charge which may be based on a percent of a facility’s annual kW peak. It ensures collection of sufficient utility revenue to cover the cost of installed transmission and distribution even when a customer significantly cuts its peak demand.

Irving Oil hydrogen electrolyzer expands green hydrogen capacity at the Saint John refinery with Plug Power technology, cutting carbon emissions, enabling clean fuel for buses, and supporting Atlantic Canada decarbonization and renewable grid integration.

Key Points

A 5 MW Plug Power unit at Irving's Saint John refinery producing low-carbon hydrogen via electrolysis.

✅ Produces 2 tonnes/day, enough to fuel about 60 hydrogen buses

✅ Uses grid power; targets cleaner supply via renewables and nuclear

✅ First Canadian refinery investing in electrolyzer technology

Irving Oil is expanding hydrogen capacity at its Saint John, N.B., refinery in a bid to lower carbon emissions and offer clean energy to customers.

The family-owned company said Tuesday it has a deal with New York-based Plug Power Inc. to buy a five-megawatt hydrogen electrolyzer that will produce two tonnes of hydrogen a day — equivalent to fuelling 60 buses with hydrogen — using electricity from the local grid and drawing on examples such as reduced electricity rates proposed in Ontario to grow the hydrogen economy.

Hydrogen is an important part of the refining process as it's used to lower the sulphur content of petroleum products like diesel fuel, but most refineries produce hydrogen using natural gas, which creates carbon dioxide emissions and raises questions explored in hydrogen's future for power companies in the energy sector.

"Investing in a hydrogen electrolyzer allows us to produce hydrogen in a very different way," Irving director of energy transition Andy Carson said in an interview.

"Instead of using natural gas, we're actually using water molecules and electricity through the electrolysis process to produce ... a clean hydrogen."

Irving plans to continue to work with others in the province to decarbonize the grid amid pressures like Ontario's push into energy storage as electricity supply tightens and ensure the electricity being used to power its hydrogen electrolyzer is as clean as possible, he said.

N.B. Power's electrical system includes 14 generating stations powered by hydro, coal, oil, wind, nuclear and diesel. The utility has committed to increasing its renewable energy sources and exploring innovations such as EV-to-grid integration piloted in Nova Scotia.

Irving said it will be the first oil refinery in Canada to invest in electrolyzer technology, as Ontario's Hydrogen Innovation Fund supports broader deployment nationwide.

The company said its goal is to offer hydrogen fuelling infrastructure in Atlantic Canada, complementing N.L.'s fast-charging network for EV drivers in the region.

"This kind of investment allows us to not just move to a cleaner form of hydrogen in the refinery. It also allows us to store and make hydrogen available to the marketplace," Carson said.

Federal watchdog warns Canada's 2030 emissions target may not be achievable
The hydrogen technology will help Irving "unlock pent up demand for hydrogen as an energy transition fuel for logistics organizations," he said.

Alberta also aims to expand its hydrogen production over the coming years, alongside British Columbia's $900 million hydrogen project moving ahead on the West Coast. 

Those plans lean on the development of carbon capture and storage (CCS) technology that aims to trap the emissions created when producing hydrogen from natural gas.

Japan Electricity Crunch exposes vulnerabilities in a liberalised power market as LNG shortages, JEPX price spikes, snow-hit solar, and weak hedging strain energy security and retail providers amid cold snap demand and limited reserve capacity.

Key Points

A winter demand shock and LNG shortfalls sent JEPX to records, exposing gaps in hedging, data, and energy security.

✅ JEPX wholesale prices spiked to an all-time high

✅ LNG inventories and procurement proved insufficient

✅ Snow disabled solar; new entrants lacked hedging

Japan's worst electricity crunch since the aftermath of the Fukushima crisis has exposed vulnerabilities in the country's recently liberalised power market, although some of the problems appear self-inflicted.

Power prices in Japan hit record highs last month, mirroring UK peak power prices during tight conditions, as a cold snap across northeast Asia prompted a scramble for supplies of liquefied natural gas (LNG), a major fuel for the country's power plants. Power companies urged customers to ration electricity to prevent blackouts, although no outages occurred.

The crisis highlighted how many providers were unprepared for such high demand. Experts say LNG stocks were not topped up ahead of winter and snow disabled solar power farms, while China's power woes strained solar supply chains.

The hundreds of small power companies that sprang up after the market was opened in 2016 have struggled the most, saying the government does not disclose the market data they need to operate. The companies do not have their own generators, instead buying electricity on the wholesale market.

Prices on the Japan Electric Power Exchange (JEPX) hit a record high of 251 yen ($2.39) per kilowatt hour in January, equating to $2,390 per megawatt hour of electricity, above record European price surges seen recently and the highest on record anywhere in the world. One megawatt hour is roughly what an average home in the U.S. would consume over 35 days.

But the vast majority of the new, smaller companies are locked into low, fixed rates they set to lure customers from bigger players, crushing them financially during a price spike like the one in January.

More than 50 small power providers wrote on Jan. 18 to Japan's industry minister, Hiroshi Kajiyama, who oversees the power sector, asking for more accessible data on supply and demand, reserve capacity and fuel inventories.

"By organising and disclosing this information, retail electricity providers will be able to bid at more appropriate prices," said the companies, led by Looop Co.

They also called on Kajiyama to require transmission and distribution companies to pass on some of the unexpected profits from price spikes to smaller operators.

The industry ministry said it had started releasing more timely market data, and is reviewing the cause of the crunch and considering changes, echoing calls by Fatih Birol to keep electricity options open amid uncertainty.

Japan reworked its power markets after the Fukushima nuclear disaster in 2011, liberalizing the sector in 2016 while pushing for more renewables.

But Japan is still heavily reliant on LNG and coal, and only four of 33 nuclear reactors are operating. The power crisis has led to growing calls to restart more reactors.

Kazuno Power, a small retail provider controlled by a municipality of the same name in northern Japan, where abundant renewable energy is locally produced, buys electricity from hydropower stations and JEPX.

During the crunch, the company had to pay nearly 10 times the usual price, Kazuno Power president Takao Takeda said in an interview. Like most other new providers, it could not pass on the costs, lost money, and folded. The local utility has taken over its customers.

"There is a contradiction in the current system," Takeda said. "We are encouraged to locally produce power for local consumption as well as use more renewable energy, but prices for these power supplies are linked to wholesale prices, which depend on the overall power supply."

The big utilities, which receive most of their LNG on long-term contracts, blamed the power shortfall on a tight spot market and glitches at generation units.

"We were not able to buy as much supply as we wanted from the spot market because of higher demand from South Korea and China, where power cuts have tightened supply," Kazuhiro Ikebe, the head of the country's electricity federation, said recently.

Ikebe is also president of Kyushu Electric Power, which supplies the southern island of Kyushu.

Utilities took extreme measures - from burning polluting fuel oil in coal plants to scavenging the dregs from empty LNG tankers - to keep the grid from breaking down.

"There is too much dependence on JEPX for procurement," said Bob Takai, the local head of European Energy Exchange, where electricity pricing reforms are being discussed, and which started offering Japan power futures last year. He added that new entrants were not hedging against sharp price moves.

Three people, who requested anonymity because of the sensitivity of the matter, were more blunt. One called the utilities arrogant in assuming they could find LNG cargoes in a pinch. Prices were already rising as China snapped up supplies, the sources noted.

"You had volatility caused by people saying 'Oh, well, demand is going to be weak because of coronavirus impacts' and then saying 'we can rely more on solar than in the past,' but solar got snowed out," said a senior executive from one generator. "We have a problem of who is charge of energy security in Japan."

Inventories of LNG, generally about two weeks worth of supplies, were also not topped up enough to prepare for winter, a market analyst said.

The fallout from the crunch has become more apparent in recent days, with new power companies like Rakuten Inc suspending new sales and Tokyo Gas, along with traditional electricity utilities, issuing profit downgrades or withdrawing their forecasts.

Although prices have fallen sharply as temperatures warmed up slightly and more generation units have come back online, the power generator executive said, "we are not out of the woods yet."

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.
