Environment Department sues El Paso Electric

Nova Scotia Integrated Resource Plan evaluates NSPI supply options, UARB oversight, Muskrat Falls imports, coal retirements, wind and biomass expansion, transmission upgrades, storage, and least-cost pathways to decarbonize the grid for ratepayers.

Key Points

A 25-year roadmap assessing supply, imports, costs, and emissions to guide least-cost decarbonization for Nova Scotia.

✅ Compares wind, biomass, gas, imports, and storage costs

✅ Addresses coal retirements, emissions caps, and reliability

✅ Recommends transmission upgrades and Muskrat Falls utilization

Maintaining a viable electricity network requires good long-term planning and, as a recent grid operations report notes, ongoing operational improvements. The existing stock of generating assets can become obsolete through aging, changes in fuel prices or environmental considerations. Future changes in demand must be anticipated.

Periodically, an integrated resource plan is created to predict how all this will add up during the ensuing 25 years. That process is currently underway and is led by Nova Scotia Power Inc. (NSPI) and will be submitted for approval to the Utilities and Review Board (UARB).

Coal-fired plants are still the largest single source of electricity in Nova Scotia. They need to be replaced with more environmentally friendly sources when they reach the end of their useful lives. Other sources include wind, hydroelectricity from rivers, biomass, as seen in increased biomass use by NS Power, natural gas and imports from other jurisdictions.

Imports are used sparingly today but will be an important source when the electricity from Muskrat Falls comes on stream. That project has big capacity. It can produce all the power needed in Newfoundland and Labrador (NL), where Quebec's power ambitions influence regional flows, plus the amount already committed to Nova Scotia, and still have a lot left over.

Some sources of electricity are more valuable than others. The daily amount of power from wind and solar cannot be controlled. Fuel-based sources and hydro can.

Utilities make their profits by providing the capital necessary to build infrastructure. Most of the money is borrowed but a portion, typically 30 per cent, usually comes from NSPI or a sister company. On that they receive a rate of return of nine per cent. Nova Scotia can borrow money today at less than two per cent.

The largest single investment of that type is the $1.577-billion Maritime Link connecting power from Newfoundland to Nova Scotia. It continues through to the New Brunswick border to facilitate exports to the United States. NSPI’s sister company, NSP Maritime Link Inc. (NSPML), is making nine per cent on $473 million of the cost.

There is little unexploited hydro capacity in Nova Scotia and there will not be any new coal-fired plants. Large-scale solar is not competitive in Nova Scotia’s climate. Nova Scotia’s needs would not accommodate the amount of nuclear capacity needed to be cost-effective, even as New Brunswick explores small reactors in its strategy.

So the candidates for future generating resources are wind, natural gas, biomass (though biomass criticism remains) and imports from other jurisdictions. Tidal is a promising opportunity but is still searching for a commercially viable technology. 

NSPI is commendably transparent about its process (irp.nspower.ca). At this stage there is little indication of the conclusions they are reaching but that will presumably appear in due course.

The mountains of detail might obscure the fact that NSPI is not an unbiased arbiter of choices for the future.

It is reported that they want to prematurely close the Trenton 5 coal plant in 2023-25. It is valued at $88.5 million. If it is closed early, ratepayers will still have to pay off the remaining value even though the plant will be idle. NSPI wants to plan a decommissioning of five of its other seven plants. There is a federal emissions constraint but retiring coal plants earlier than needed will cost ratepayers a lot.

Whenever those plants are closed, there will be a need for new sources of power. NSPI is proposing to plan for new investments in new transmission infrastructure to facilitate imports. Other possibilities would be additional wind farms, consistent with the shift to more wind and solar projects, thermal plants that burn natural gas or biomass, or storage for excess wind power that arrives before it can be used. The investment in storage could be anywhere from $20 million to $200 million.

These will add to the asset burden funded by ratepayers, even as industrial customers seek discounts while still paying for shuttered coal infrastructure.

External sources of new power will not provide NSPI the same opportunity: wind power by independent producers might be less expensive because they are willing to settle for less than nine per cent or because they are more efficient. Buying more power from Muskrat Falls will use transmission infrastructure we are already paying for. If a successful tidal technology is found, it will not be owned by NSPI or a sister company, which are no longer trying to perfect the technology.

This is not to suggest that NSPI would misrepresent the alternatives. But they can tilt the discussion in their favour. How tough will they be negotiating for additional Muskrat Falls power when it hurts their profits? Arguing for premature coal retirement on environmental grounds is fair game but whether the cost should be accepted is a political choice. 

NSPI is in a conflict of interest. We need a different process. An independent body should author the integrated resource plan. They should be fully informed about NSPI’s views.

They should communicate directly with Newfoundland and Labrador for Muskrat power, with independent wind producers, and with tidal power companies. The UARB cannot do any of these things.

The resulting plan should undergo the same UARB review that NSPI’s version would. This enhances the likelihood that Nova Scotians will get the least-cost alternative.

ISEM Price Volatility reflects Ireland-Northern Ireland grid balancing pressures, driven by dispatchable power shortages, day-ahead market dynamics, renewable shortfalls, and interconnector constraints, affecting intraday trading, operational reserves, and cross-border electricity flows.

Key Points

ISEM price volatility is Irish power price swings from grid balancing stress and limited dispatchable capacity.

✅ One-off spike linked to plant outage and low renewables

✅ Day-ahead market settling; intraday trading integration pending

✅ Interconnectors and reserves vital to manage adequacy

Irish grid-balancing prices soared to €3,774 ($4,284) per megawatt-hour last month amid growing concerns over dispatchable power capacity across Europe.

The price spike, triggered by an alert regarding generation losses, came only four months after Ireland and Northern Ireland launched an Integrated Single Electricity Market (ISEM) designed to make trading more competitive and improve power distribution across the island.

Evie Doherty, senior consultant for Ireland at Cornwall Insight, a U.K.-based energy consultancy, said significant price volatility was to be expected while ISEM is still settling down, aligning with broader 2019 grid edge trends seen across markets.

When the U.K. introduced a single market for Great Britain, called British Electricity Trading and Transmission Arrangements, in 2005, it took at least six months for volatility to subside, Doherty said.

In the case of ISEM, “it will take more time to ascertain the exact drivers behind the high prices,” she said. “We are being told that the day-ahead market is functioning as expected, but it will take time to really be able to draw conclusions on efficiency.”

Ireland and Northern Ireland have been operating with a single market “very successfully” since 2007, said Doherty. Although each jurisdiction has its own regulatory authority, they make joint decisions regarding the single market.

ISEM, launched in October 2018, was designed to help include Ireland and Northern Ireland day-ahead electricity prices in a market pricing system called the European Union Pan-European Hybrid Electricity Market Integration Algorithm.

In time, ISEM should also allow the Irish grids to participate in European intraday markets, and recent examples like Ukraine's grid connection underline the pace of integration efforts across Europe. At present, they are only able to do so with Great Britain. “The idea was to...integrate energy use and create more efficient flows between jurisdictions,” Doherty said.

EirGrid, the Irish transmission system operator, has reported that flows on its interconnector with Northern Ireland are more efficient than before, she said.

The price spike happened when the System Operator for Northern Ireland issued an alert for an unplanned plant outage at a time of low renewable output and constraints on the north-south tie-line with Ireland, according to a Cornwall Insight analysis.

Not an isolated event

Although it appears to have been a one-off event, there are increasing worries that a shortage of dispatchable power could lead to similar situations elsewhere across Europe, as seen in Nordic grid constraints recently.

Last month, newspaper Frankfurter Allgemeine Zeitung (FAZ) reported that German industrial concerns had been forced to curtail more than a gigawatt of power consumption to maintain operational reserves on the grid in December, after renewable production fell short of expectations and harsh weather impacts strained systems elsewhere.

Paul-Frederik Bach, a Danish energy consultant, has collected data showing that this was not an isolated incident. The FAZ report said German aluminum smelters had been forced to cut back on energy use 78 times in 2018, he noted.

Energy availability was also a concern last year in Belgium, where six out of seven nuclear reactors had been closed for maintenance. The closures forced Belgium to import 23 percent of its electricity from neighboring countries, Bach reported.

In a separate note, Bach revealed that 11 European countries that were net importers of energy had boosted their imports by 26 percent between 2017 and 2018. It is important to note that electricity imports do not necessarily imply a shortage of power, he stated.

However, it is also true that many European grid operators are girding themselves for a future in which dispatchable power is scarcer than today.

EirGrid, for example, expects dispatchable generation and interconnection capacity to drop from 10.6 gigawatts in 2018 to 9 gigawatts in 2027.

The Swedish transmission system operator Svenska Kraftnät, meanwhile, is forecasting winter peak power deficits could rise from 400 megawatts currently to 2.5 gigawatts in 2020-21.

Research conducted by the European Network of Transmission System Operators for Electricity, suggests power adequacy will fall across most of Europe up to 2025, although perhaps not to a critical degree.

The continent’s ability to deal with the problem will be helped by having more efficient trading systems, Bach told GTM. That means developments such as ISEM could be a step in the right direction, despite initial price volatility.

In the long run, however, Europe will need to make sure market improvements are accompanied by investments in HVDC technology and interconnectors and reserve capacity. “Somewhere there must be a production of electricity, even when there is no wind,” said Bach.

EV Grid Capacity Management shows how smart charging, load balancing, and off-peak pricing align with utility demand response, DC fast charging networks, and renewable integration to keep national electricity infrastructure reliable as EV adoption scales

Key Points

EV Grid Capacity Management schedules charging and balances load to keep EV demand within utility capacity.

✅ Off-peak pricing and time-of-use tariffs shift charging demand.

✅ Smart chargers enable demand response and local load balancing.

✅ Gradual EV adoption allows utilities to plan upgrades efficiently.

One of the most frequent concerns you will see from electric vehicle haters is that the electricity grid can’t possibly cope with all cars becoming EVs, or that EVs will crash the grid entirely. However, they haven’t done the math properly. The grids in most developed nations will be just fine, so long as the demand is properly management. Here’s how.

The biggest mistake the social media keyboard warriors make is the very strange assumption that all cars could be charging at once. In the UK, there are currently 32,697,408 cars according to the UK Department of Transport. The UK national grid had a capacity of 75.8GW in 2020. If all the cars in the UK were EVs and charging at the same time at 7kW (the typical home charger rate), they would need 229GW – three times the UK grid capacity. If they were all charging at 50kW (a common public DC charger rate), they would need 1.6TW – 21.5 times the UK grid capacity. That sounds unworkable, and this is usually the kind of thinking behind those who claim the UK grid can't cope with EVs.

What they don’t seem to realize is that the chances of every single car charging all at once are infinitesimally low. Their arguments seem to assume that nobody ever drives their car, and just charges it all the time. If you look at averages, the absurdity of this position becomes particularly clear. The distance each UK car travels per year has been slowly dropping, and was 7,400 miles on average in 2019, again according to the UK Department of Transport. An EV will do somewhere between 2.5 and 4.5 miles per kWh on average, so let’s go in the middle and say 3.5 miles. In other words, each car will consume an average of 2,114kWh per year. Multiply that by the number of cars, and you get 69.1TWh. But the UK national grid produced 323TWh of power in 2019, so that is only 21.4% of the energy it produced for the year. Before you argue that’s still a problem, the UK grid produced 402TWh in 2005, which is more than the 2019 figure plus charging all the EVs in the UK put together. The capacity is there, and energy storage can help manage EV-driven peaks as well.

Let’s do the same calculation for the USA, where an EV boom is about to begin and planning matters. In 2020, there were 286.9 million cars registered in America. In 2020, while the US grid had 1,117.5TW of utility electricity capacity and 27.7GW of solar, according to the US Energy Information Administration. If all the cars were EVs charging at 7kW, they would need 2,008.3TW – nearly twice the grid capacity. If they charged at 50kW, they would need 14,345TW – 12.8 times the capacity.

However, in 2020, the US grid generated 4,007TWh of electricity. Americans drive further on average than Brits – 13,500 miles per year, according to the US Department of Transport’s Federal Highway Administration. That means an American car, if it were an EV, would need 3,857kWh per year, assuming the average efficiency figures above. If all US cars were EVs, they would need a total of 1,106.6TWh, which is 27.6% of what the American grid produced in 2020. US electricity consumption hasn’t shrunk in the same way since 2005 as it has in the UK, but it is clearly not unfeasible for all American cars to be EVs. The US grid could cope too, even as state power grids face challenges during the transition.

After all, the transition to electric isn’t going to happen overnight. The sales of EVs are growing fast, with for example more plug-ins sold in the UK in 2021 so far than the whole of the previous decade (2010-19) put together. Battery-electric vehicles are closing in on 10% of the market in the UK, and they were already 77.5% of new cars sold in Norway in September 2021. But that is new cars, leaving the vast majority of cars on the road fossil fuel powered. A gradual introduction is essential, too, because an overnight switchover would require a massive ramp up in charge point installation, particularly devices for people who don’t have the luxury of home charging. This will require considerable investment, but could be served by lots of chargers on street lamps, which allegedly only cost £1,000 ($1,300) each to install, usually with no need for extra wiring.

This would be a perfectly viable way to provide charging for most people. For example, as I write this article, my own EV is attached to a lamppost down the street from my house. It is receiving 5.5kW costing 24p (32 cents) per kWh through SimpleSocket, a service run by Ubitricity (now owned by Shell) and installed by my local London council, Barnet. I plugged in at 11am and by 7.30pm, my car (which was on about 28% when I started) will have around 275 miles of range – enough for a couple more weeks. It will have cost me around £12 ($16) – way less than a tank of fossil fuel. It was a super-easy process involving the scanning of a QR code and entering of a credit card, very similar to many parking systems nowadays. If most lampposts had one of these charging plugs, not having off-street parking would be no problem at all for owning an EV.

With most EVs having a range of at least 200 miles these days, and the average mileage per day being 20 miles in the UK (the 7,400-mile annual figure divided by 365 days) or 37 miles in the USA, EVs won’t need charging more than once a week or even every week or two. On average, therefore, the grids in most developed nations will be fine. The important consideration is to balance the load, because if too many EVs are charging at once, there could be a problem, and some regions like California are looking to EVs for grid stability as part of the solution. This will be a matter of incentivizing charging during off-peak times such as at night, or making peak charging more expensive. It might also be necessary to have the option to reduce charging power rates locally, while providing the ability to prioritize where necessary – such as emergency services workers. But the problem is one of logistics, not impossibility.

There will be grids around the world that are not in such a good place for an EV revolution, at least not yet, and some critics argue that policies like Canada's 2035 EV mandate are unrealistic. But to argue that widespread EV adoption will be an insurmountable catastrophe for electricity supply in developed nations is just plain wrong. So long as the supply is managed correctly to make use of spare capacity when it’s available as much as possible, the grids will cope just fine.

Neste wind power agreement boosts renewable electricity in Finland, partnering with Ilmatar and Fortum to supply Porvoo and Naantali sites, cutting Scope 2 emissions and advancing a 2035 carbon-neutral production target via long-term PPAs.

Key Points

A PPA to source wind power for sites, cutting Scope 2 emissions and supporting Neste's 2035 carbon-neutral goal.

✅ 10-year PPA with Ilmatar; + Fortum boosts renewable electricity share.

✅ Supplies ~7% of Porvoo-Naantali electricity; capacity >20 MW.

✅ Cuts Scope 2 emissions by ~55 kt CO2e per year toward 2035 neutrality.

Neste is committed to reaching carbon neutral production by 2035, mirroring efforts such as Olympus 100% renewable electricity commitments across industry.

As part of this effort, the company is increasing the use of renewable electricity at its production sites in Finland, reflecting trends such as Ireland's green electricity targets across Europe, and has signed a wind power agreement with Ilmatar, a wind power company. The agreement has been made together with Borealis, Neste's long-term partner in the Kilpilahti area in Porvoo, Finland.

As a result of the agreement with Ilmatar, as well as that signed with Fortum at the end of 2019, and in line with global growth such as Enel's 450 MW wind project in the U.S., nearly 30% of the energy used at Neste's production sites in Porvoo and Naantali will be renewable wind power in 2022.

'Neste's purpose is to create a healthier planet for our children. Our two climate commitments play an important role in living up to this ambition, and one of them is to reach carbon neutral production by 2035. It is an enormous challenge and requires several concrete measures and investments, including innovations like offshore green hydrogen initiatives. Wind power, including advances like UK offshore wind projects, is one of the over 70 measures we have identified to reduce our production's greenhouse gas emissions,' Neste's President and CEO Peter Vanacker says.

With the ten year contract, Neste is committed to purchase about one-third of the production of Ilmatar's two wind farms, reflecting broader market moves such as BC Hydro wind deals in Canada. The total capacity of the agreement is more than 20 MW, and the energy produced will correspond to around 7% of the electricity consumption at Neste's sites in Porvoo and Naantali. The wind power deliveries are expected to begin in 2022.

The two wind power agreements help Neste to reduce the indirect greenhouse gas emissions (Scope 2 emissions defined by the Greenhouse Gas Protocol) of electricity purchases at its Finnish production sites, a trend mirrored by Dutch green electricity growth across Europe, annually by approximately 55 kilotons. 55 kt/a CO2e equals annual carbon footprint of more than 8,500 EU citizens.

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.

Hurricane Ida New Orleans Infrastructure faced a split outcome: levees and pumps protected against storm surge, while the power grid collapsed as transmission lines failed, prompting large-scale restoration efforts across Louisiana and Mississippi.

Key Points

It summarizes Ida's impact: levees and pumps held, but the power grid failed, causing outages and slow restoration.

✅ Levees and pumps mitigated flooding and storm surge impacts.

✅ All transmission lines failed, crippling the power grid.

✅ Crews and drones assess damage; restoration may take weeks.

Infrastructure in the city of New Orleans turned in a mixed performance against the fury of Hurricane Ida, with the levees and pumps warding off catastrophic flooding even as the electrical grid, part of the broader Louisiana power grid, failed spectacularly.

Ida’s high winds, measuring 150 miles (240 kilometers) an hour at landfall, took out all eight transmissions lines that deliver power into New Orleans, ripped power poles in half and crumpled at least one steel transmission tower into a twisted metal heap, knocking out electricity to all of the city. A total of more than 1.2 million homes and businesses in Louisiana and Mississippi lost power. While about 90,000 customers were reconnected by Monday afternoon, many could face days without electricity, and frustration can mount as seen during the Houston outage after major storms.

In contrast, the New Orleans area’s elaborate flood defenses seem to have held up, a vindication of the Army Corps of Engineers’ $14.5 billion project to rebuild levees, flood gates and pumps in the wake of the devastation wrought by Hurricane Katrina in 2005. While there were reports of scattered deaths tied to Ida, the city escaped the kind of flooding that destroyed entire neighborhoods in Katrina’s wake, left parts of the city uninhabitable for months and claimed 1,800 lives. 

“The situation in New Orleans, as bad as it is today with the power, could be so much worse,” Louisiana Governor John Bel Edwards said Monday on the Today Show, praising the levee system’s performance. “All you have to do is go back 16 years to get a glimpse of what that would have been like.”

While the levees’ resiliency is no doubt due to the rebuilding effort that followed Katrina, the starkly different outcomes also stems from the storms’ different characteristics. Katrina slammed the coast with a 30-foot storm surge of ocean water, while preliminary estimates from Ida put its surge far lower. 

Ida’s winds, however, were stronger than Katrina’s, and that’s what ultimately took out so many power lines, a dynamic that also saw Texas utilities struggle during Harvey. Deanna Rodriguez, the chief executive officer of power provider Entergy New Orleans, declined to comment on when service would be restored, saying the company was using helicopters and drones to help assess the damage.

Michael Webber, an energy and engineering professor at the University of Texas at Austin, estimated power restoration will take days and possibly weeks, a pattern seen in Florida restoration timelines after major hurricanes, based on the initial damage reports from the storm. More than 25,000 workers from at least 32 states and Washington are mobilized to assist with power restoration efforts, similar to FPL's massive response after Irma, according to the Edison Electric Institute.

“The question is, how long will it take to rebuild these lines,” Webber said. The utilities will first need to complete their damage assessments before they can get a sense of repair timelines, a step that Gulf Power crews have highlighted in past recoveries, he said. “You can imagine that will take days at least, possibly weeks.”

The loss of electricity will have other affects as well, and even though grid resilience during the pandemic was strong, local systems face immediate constraints. Sewer substations, for example, need electricity to keep wastewater moving, said Ghassan Korban, executive director of the New Orleans Sewerage & Water Board. The storm knocked out power to about 80 of the city’s 84 pumping stations, he said at a Monday press conference. “Without electricity, wastewater backs up and can cause overflows,” he said, adding that residents should conserve water to lessen stress on the system.
