Court ruling on mercury shakes up coal plants

Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.

Key Points

Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.

✅ Balances variable renewables with dispatchable generation

✅ Rewards flexibility via capacity markets and ancillary services

✅ Enhances grid stability for critical loads during low demand

The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.

In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."

Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.

"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.

"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.

"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."

In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.

"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.

"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."

Yukon-BC Electricity Intertie could link Yukon to BC's hydroelectric power, enabling renewable energy integration, net-zero grid goals by 2035, transmission expansion for mining, and stronger Arctic energy security through a coast-to-coast network.

Key Points

A link connecting Yukon's grid to BC hydro to import renewables, cut emissions, and strengthen northern energy security.

✅ Enables renewable imports to meet 2035 net-zero electricity target

✅ Supports mining growth with reliable, low-carbon power

✅ Enhances Arctic energy security via national grid integration

Yukon's energy minister says Canada's push for more green energy and a net-zero electricity grid should spark renewed interest in connecting the territory's power to British Columbia, home to the Electric Highway network.

Minister of Energy, Mines and Resources John Streicker says linking the territory's power grid to the south would help with the national move to renewable energy, including new wind turbines being added in the Yukon, support the mineral extraction required for green projects, and improve northern energy and Arctic security.

"We're getting to the moment in time when we will want an electricity grid which stretches from coast to coast to coast. … I think that the moment is coming for this — it's sort of a nation-building moment. And I think that from the Yukon's perspective, we're very interested," Streicker said in an interview.

The idea of a link, originally proposed to span 763 kilometres between Whitehorse and Iskut, B.C., was first floated in 2016 but sat on the shelf after a viability study put the price tag at as much as $1.7 billion, even as a study indicates B.C. may need to double its power output to electrify all road vehicles.

Two years later, Yukon's then-energy-minister Ranj Pillai — now premier — mused again about the possibility of connecting to power from B.C., where green energy ambitions include the Site C hydro dam.

The idea appeared to have been resurrected at this year's Western Premiers' Conference in June, with both Pillai and B.C. Premier David Eby publicly mentioning early conversations about grid development and interties.

At the conference, Eby said British Columbia was fortunate to have the ability to support other jurisdictions with its hydro electricity.

"So certainly part of the conversation was how do we support each other in sharing our strength, including emerging hydrogen projects across the province?" he said.

"And one of those that British Columbia was able to put on the table is if we can find ways to enter ties with, for example, with the Yukon, to support them in their efforts to access more electricity to grow their economy and decarbonize their electrical grid, then that's very good news for everybody."

The federal government has set a target of making the country's electricity grid net-zero by 2035, while jurisdictions like the N.W.T. plan for more residents to drive electric vehicles as part of the transition.

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.

Key Points

A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.

✅ PUB flags potential rate shock from proposed adjustment

✅ RSP balances cited to offset increases without depleting fund

✅ Oil-fired Holyrood volatility drives fuel cost uncertainty

How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?

That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.

"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.

NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.

"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.

It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.

The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.

The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."

Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.

'Unacceptable' burden: Consumer Advocate

"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.

Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.

"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.

"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.

Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.

Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.

It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.

EU Electricity Market Reform seeks to curb gas-driven volatility by expanding CfDs and PPAs, decoupling power from gas, and aligning consumer bills with low-cost renewables and nuclear, as Brussels advances market redesign.

Key Points

An EU plan to curb price spikes by expanding long-term contracts and tying bills to cheap renewables.

✅ Expands CfDs and PPAs to lock in predictable power prices

✅ Aims to decouple bills from gas-driven wholesale volatility

✅ Seeks investment certainty for renewables, nuclear, and grids

European Union energy ministers meet on Monday to debate upcoming power market reforms. Brussels is set to propose the revamp next month, but already countries are split over how to "fix" the energy system - or whether it needs fixing at all.

Here's what you need to know.

POST-CRISIS CHANGES
The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices - caused by cuts to Russian gas flows - sent power prices soaring during an energy crisis for European companies and citizens.

The aim is to reform the electricity market to shield consumer energy bills from short-term swings in fossil fuel prices, and make sure that Europe's growing share of low-cost renewable electricity translates into lower prices, even though rolling back electricity prices poses challenges for policymakers.

Currently, power prices in Europe are set by the running cost of the plant that supplies the final chunk of power needed to meet overall demand. Often, that is a gas plant, so gas price spikes can send electricity prices soaring.

EU countries disagree on how far the reforms should go.

Spain, France and Greece are among those seeking a deep reform.

In a document shared with EU countries, seen by Reuters, Spain said the reforms should help national regulators to sign more long-term contracts with electricity generators to pay a fixed price for their power.

Nuclear and renewable energy producers, for example, would receive a "contract for difference" (CfD) from the government to provide power during their lifespan - potentially decades - at a stable price that reflects their average cost of production.

Similarly, France suggests, as part of a new electricity pricing scheme, requiring energy suppliers to sign long-term, fixed-price contracts with power generators - either through a CfD, or a private Power Purchase Agreement (PPA) between the parties.

French officials say this would give the power plant owner predictable revenue, while enabling consumers to have part of their energy bill comprised of this more stable price.

Germany, Denmark, Latvia and four other countries oppose a deep reform, and, as nine EU countries oppose reforms overall, have warned the EU against a "crisis mode" overhaul of a complex system that has taken decades to develop.

They say Europe's existing power market is functioning well, and has fostered years of lower power prices, supported renewable energy and helped avoid energy shortages.

Those countries support only limited tweaks, such as making it easier for consumers to choose between fluctuating and fixed-price power contracts.

'DECOUPLE' PRICES?
The Commission initially pitched the reform as a chance to "decouple" gas and power prices in Europe, suggesting a redesign of the current system of setting power prices. But EU officials say Brussels now appears to be leaning towards more modest changes.

A public consultation on the reforms last month steered clear of a deep energy market intervention. Rather, it suggested expanding Europe's use of long-term contracts, outlining a plan for more fixed-price contracts that provide power plants with a fixed price for their electricity, like CfDs or PPAs.

The Commission said this could be done by setting EU-wide rules for CfDs and letting countries voluntarily use them, or require new state-funded power plants to sign CfDs. The consultation mooted the idea of forcing existing power plants to sign CfDs, but said this could deter much-needed investments in renewable energy.

RISKS, REWARDS
Pro-reform countries like Spain say a revamped power market will bring down energy prices for consumers, by matching their bills more closely with the true cost of producing lower-carbon electricity.

France says the aim is to secure investment in low-carbon energy including renewables, and nuclear plants like those Paris plans to build. It also says lowering power prices should be part of Europe's response to massive industrial subsidies in the United States and China - by helping European firms keep a competitive edge.

But sceptics warn that drastic changes to the market could knock confidence among investors, putting at risk the hundreds of billions of euros in renewable energy investments the EU says are needed to quit Russian fossil fuels under its plan to dump Russian energy and meet climate goals.

Energy companies including Engie (ENGIE.PA), Orsted (ORSTED.CO) and Iberdrola (IBE.MC) have said making CfDs mandatory or imposing them retroactively on existing power plants could deter investment and trigger litigation from energy companies.

POLITICAL DEBATE
EU countries' energy ministers discuss the reforms on Monday, before formal negotiations begin.

The Commission, which drafts EU laws, plans to propose the reforms on Mar. 14. After that, EU countries and lawmakers negotiate the final law, which must win majority support from European Parliament lawmakers and a reinforced majority of at least 15 countries.

Negotiations on major EU legislation often take more than a year, but some countries are pushing for a fast-tracked deal. France wants the law to be finished this year.

That has already hit resistance from countries like Germany, highlighting a France-Germany tussle over the scope of reform as they say deeper changes cannot be rushed through, and they would need an "in-depth impact assessment" - something the Commission's upcoming proposal is not expected to include, because it has been drafted so quickly.

The timeline is further complicated by European Parliament elections in 2024. That has raised concerns in reform-hungry states that failure to strike a deal before the election could significantly delay the reforms, if negotiations have to pause until a new EU parliament is elected.

British Columbia Green Grid Constraints underscore BC Hydro's rising imports, peak demand, electrification, hydroelectric variability, and transmission bottlenecks, challenging renewable energy expansion, energy security, and CleanBC targets across industry and zero-emission transportation.

Key Points

They are capacity and supply limits straining B.C.'s clean electrification, driving imports and risking reliability.

✅ Record 25% imports in FY2024 raise emissions and costs

✅ Peak demand and transmission limits delay new connections

✅ Drought reduces hydro output; diversified generation needed

British Columbia's ambitious green energy initiatives are encountering significant hurdles due to a strained electrical grid and increasing demand, with a EV demand bottleneck adding pressure. The province's commitment to reducing carbon emissions and transitioning to renewable energy sources is being tested by the limitations of its current power infrastructure.

Rising Demand and Dwindling Supply

In recent years, B.C. has experienced a surge in electricity demand, driven by factors such as population growth, increased use of electric vehicles, and the electrification of industrial processes. However, the province's power supply has struggled to keep pace, and one study projects B.C. would need to at least double its power output to electrify all road vehicles. In fiscal year 2024, BC Hydro imported a record 13,600 gigawatt hours of electricity, accounting for 25% of the province's total consumption. This reliance on external sources, particularly from fossil-fuel-generated power in the U.S. and Alberta, raises concerns about energy security and sustainability.

Infrastructure Limitations

The current electrical grid is facing capacity constraints, especially during peak demand periods, and regional interties such as a proposed Yukon connection are being discussed to improve reliability. A report from the North American Electric Reliability Corporation highlighted that B.C. could be classified as an "at-risk" area for power generation as early as 2026. This assessment underscores the urgency of addressing infrastructure deficiencies to ensure a reliable and resilient energy supply.

Government Initiatives and Investments

In response to these challenges, the provincial government has outlined plans to expand the electrical system. Premier David Eby announced a 10-year, $36-billion investment to enhance the grid's capacity, including grid development and job creation measures to support local economies. The initiative focuses on increasing electrification, upgrading high-voltage transmission lines, refurbishing existing generating facilities, and expanding substations. These efforts aim to meet the growing demand and support the transition to clean energy sources.

The Role of Renewable Energy

Renewable energy sources, particularly hydroelectric power, play a central role in B.C.'s energy strategy. However, the province's reliance on hydroelectricity has its challenges. Drought conditions in recent years have led to reduced water levels in reservoirs, impacting the generation capacity of hydroelectric plants. This variability underscores the need for a diversified energy mix, with options like a hydrogen project complementing hydro, to ensure a stable and reliable power supply.

Balancing Environmental Goals and Energy Needs

B.C.'s commitment to environmental sustainability is evident in its policies, such as the CleanBC initiative, which aims to phase out natural gas heating in new homes by 2030 and achieve 100% zero-emission vehicle sales by 2035, supported by networks like B.C.'s Electric Highway that expand charging access. While these goals are commendable, they place additional pressure on the electrical grid. The increased demand from electric vehicles and electrified heating systems necessitates a corresponding expansion in power generation and distribution infrastructure.

British Columbia's green energy ambitions are commendable and align with global efforts to combat climate change. However, achieving these goals requires a robust and resilient electrical grid capable of meeting the increasing demand for power. The province's reliance on external power sources and the challenges posed by climate variability highlight the need for strategic investments in infrastructure and a diversified energy portfolio, guided by BC Hydro review recommendations to keep electricity affordable. By addressing these challenges proactively, B.C. can pave the way for a sustainable and secure energy future.
