In a bid to reduce dependency on coal for power generation and resort to a cleaner and less expensive source of energy, Poland is considering setting up a nuclear power plant by 2020.
While several countries of Eastern Europe have local nuclear power stations, Poland has yet to join the bandwagon. A previous nuclear power project was stalled in the communist era of the 1980s.
The country is likely to decide on locations for two nuclear sites by the end of 2009.
However, it remains to be seen whether the proposals would be of an order of magnitude large enough for Poland to begin considering nuclear power as an alternative to coal-based power. Nuclear power could well remain one of several alternatives including natural and renewable energy resources to help wean the country off of coal.
Poland is currently involved in an off-territory project to develop a nuclear power plant in Visaginas, Lithuania. The other two Baltic states, Latvia and Estonia, are also part of the four-nation project. Lithuania pledged to shut down a Soviet-era nuclear power plant by 2010 as a prerequisite for joining the European Union and plans to replace it with the proposed nuclear power station.
However, the four nations are yet to enter into agreements to formally forge the partnership. This is likely to happen by the end of 2009.
Lithuania has yet to determine the generation capacity of the proposed plant, which could reach 3,400 megawatts (MW). The project is expected to require an investment of more than $10 billion, and the first unit is likely to be constructed by 2016-18. The plant will supply power to all four nations. Estonia has also launched a feasibility study for development of a nuclear power plant, but has not arrived at a final political decision pertaining to nuclear power.
Coal-fired thermal power plants generate 94% of Poland's energy, making it the world's second most coal-dependent country after South Africa. The country has 105 coal-fed power-generation and heating plants. While the country has rich coal reserves that are estimated to last for more than a century, the country is deficient in other fossil fuels. Poland also does not enjoy favorable conditions to make an extensive transition to hydroelectric power or other renewable sources of energy such as wind farms.
Poland is likely to veto the E.U.'s goals for 2020 that involve reduction of greenhouse gas emissions by 20% from the levels in 1990, increasing the use of renewable energy to 20% of each nation's total energy consumption, and the reduction of overall energy use by 20%. Carbon-dioxide emission levels from Poland are twice the E.U.'s average levels of emissions.
According to the European Nuclear Society, 197 nuclear power plants currently operate in Europe with a total installed capacity of 170,000 MW. More than one-third of this is generated by France, which has 59 nuclear reactors in operation. Ongoing projects include the development of 14 nuclear power plants in five European nations with an aggregate capacity of 13,000 MW.
In Asia, CLP Holdings Limited, one of the two electricity producers of Hong Kong, is currently assessing the feasibility of investing in two nuclear power projects with an aggregate capacity of 2,000 MW. The firm currently holds a 25% equity stake in a joint-venture nuclear power project at Daya Bay in Shenzhen, China, with China Guangdong Nuclear Power Holding. CLP Holdings is looking to top up the share of renewable sources in its energy portfolio from more than 5% at present to 20% by 2020.
BC Hydro Clean Power Call 2024 seeks utility-scale renewable energy, including wind and solar, to meet rising electricity demand, advance clean goals, expand grid, and support Indigenous participation through competitive procurement and equity opportunities.
Key Points
BC Hydro's 2024 bid to add zero-emission wind and solar to meet rising demand and support Indigenous equity.
✅ Competitive procurement for utility-scale wind and solar
✅ Targets 3,000 GWh new greenfield by fiscal 2029
✅ Encourages Indigenous ownership and equity stakes
The Government of British Columbia (the Government or Province) has announced that BC Hydro would be moving forward with a call for new sources of 100 percent clean, renewable emission-free electricity, notably including wind and solar, even as nuclear power remains a divisive option among residents. The call, expected to launch in spring 2024, is BC Hydro's first call for power in 15 years and will seek power from larger scale projects.
Over the past decade, British Columbia has experienced a growing economy and population as well as a move by the housing, business and transportation sectors towards electrification, with industrial demand from LNG facilities also influencing load growth. As the Government highlighted in their recent announcement, the number of registered light-duty electric vehicles in British Columbia increased from 5,000 in 2016 to more than 100,000 in 2023. Zero-emission vehicles represented 18.1 percent of new light-duty passenger vehicles sold in British Columbia in 2022, the highest percentage for any province or territory.
Ultimately, the Province now expects electricity demand in British Columbia to increase by 15 percent by 2030. BC Hydro elaborated on the growing need for electricity in their recent Signposts Update to the British Columbia Utilities Commission (BCUC), and noted additions such as new generating stations coming online to support capacity. BC Hydro implemented its Signposts Update process to monitor whether the "Near-term actions" established in its 2021 Integrated Resource Plan continue to be appropriate and align with the changing circumstances in electricity demand. Those actions outline how BC Hydro will meet the electricity needs of its customers over the next 20 years. The original Near-term actions focused on demand-side management and not incremental electricity production.
In its Update, BC Hydro emphasized that increased use of electricity and decreased supply, along with episodes of importing out-of-province fossil power during tight periods, has advanced the forecast of the province's need for additional renewable energy by three years. Accordingly, BC Hydro has updated its 2021 Integrated Resource Plan to, among other things:
accelerate the timing of several Near-term actions on energy efficiency, demand response, industrial load curtailment, electricity purchase agreement renewals and utility-scale batteries; and
add new Near-term actions for BC Hydro to acquire an additional 3,000 GWh per year of new clean, renewable energy from greenfield facilities in the province able to achieve commercial operation as early as fiscal 2029, as well as approximately 700 GWh per year of new clean, renewable energy from existing facilities prior to fiscal 2029.
The Province's predictions align with Canada Energy Regulator's (CER) "Canada's Energy Future 2023" flagship report (Report) released on June 20, 2023. The Report, which looks at Canadians' possible energy futures, includes two long-term scenarios modelled on Canada reaching net-zero by 2050. Under either scenario, the electricity sector is predicted to serve as the cornerstone of the net-zero energy system, with examples such as Hydro-Quebec's decarbonization strategy illustrating this shift as it transforms and expands to accommodate increasing electricity use.
Key Details of the Call
Though not finalized, the call for power will be a competitive process, with the exact details to be designed by BC Hydro and the Province, incorporating input from the recently-formed BC Hydro Task Force made up of Indigenous communities, industry and stakeholders. This is a shift from previous calls for power, which operated as a continuous-intake program with a standing offer at a fixed rate, after projects like the Siwash Creek project were left in limbo.
Drawing on advice from Indigenous and external energy experts, the Province seeks to advance Indigenous ownership and equity interest opportunities in the electricity sector, potentially with minimum requirements for Indigenous participation in new projects to be a condition of the competitive process. The Province has also committed $140 million to the B.C. Indigenous Clean Energy Initiative (BCICEI) to support Indigenous-led power projects and their ability to respond to future electricity demand, facilitating their ability to compete in the call for power, despite their smaller size.
BC Hydro expects to initiate the call in spring 2024, with the goal of acquiring new sources of electricity as early as 2028, even as clean electricity affordability features prominently in Ontario's election discourse.
New England Clean Energy Connect advances despite court delays, installing steel poles on a Maine corridor for Canadian hydropower, while legal challenges seek environmental review; permits, jobs, and grid upgrades drive the renewable transmission project.
Key Points
An HV line in Maine delivering 1,200 MW of Canadian hydropower to New England to cut emissions and stabilize costs.
✅ Appeals court pauses 53-mile new section; upgrades continue
✅ 1,200 MW hydropower aims to cut emissions, stabilize rates
Construction on part of a $1 billion electricity transmission corridor through sparsely populated woods in western Maine is on hold because of legal action, echoing Clean Line's Iowa withdrawal amid court uncertainty, but that doesn't mean all building has been halted.
Workers installed the first of 829 steel poles Tuesday on a widened portion of the existing corridor that is part of the project near The Forks, as the groundwork is laid for the 145-mile ( 230-kilometre ) New England Clean Energy Connect, a project central to Maine's debate over the 145-mile line moving forward.
The work is getting started even though the 1st U.S. Circuit Court of Appeals delayed construction of a new 53-mile ( 85-kilometre ) section.
Three conservation groups are seeking an injunction to delay the project while they sue to force the U.S. Army Corps of Engineers to conduct a more rigorous environmental review.
In western Maine, workers already have staged heavy equipment and timber “mats” that will be used to prevent the equipment from damaging the ground. About 275 Maine workers already have been hired, and more would be hired if not for the litigation, officials said.
“This project has always promised to provide an economic boost to Maine’s economy, and we are already seeing those benefits take shape," Thorn Dickinson, CEO of the New England Clean Energy Connect, said Tuesday.
The electricity transmission line would provide a conduit for up to 1,200 megawatts of Canadian hydropower, reducing greenhouse emissions and stabilizing energy costs in New England as states pursue Connecticut's market overhaul to improve market design, supporters say.
The project, which would be fully funded by Massachusetts ratepayers to meet the state's clean energy goals after New Hampshire rejected a Quebec-Massachusetts proposal elsewhere, calls for construction of a high-voltage power line from Mount Beattie Township on the Canadian border to the regional power grid in Lewiston, Maine.
Critics have been trying to stop the project, reflecting clashes over New Hampshire hydropower in the region, saying it would destroy wilderness in western Maine. They also say that the environmental benefits of the project have been overstated.
In addition to the lawsuit, opponents have submitted petitions seeking to have a statewide vote, even as a Maine court ruling on Hydro-Quebec exports has reshaped the legal landscape.
Sandi Howard, a leading opponent of the project, said the decision by the company to proceed showed “disdain for everyday Mainers” by ignoring permit appeals and ongoing litigation.
“For years, CMP has pushed the false narrative that their unpopular and destructive project is a ‘done deal’ to bully Mainers into submission on this for-profit project. But to be clear, we won’t stop until Maine voters (their customers), have the chance to vote,” said Howard, who led the referendum petition drive for the No CMP Corridor PAC.
The project has received permits from the Army Corps, Maine Department of Environmental Protection, Maine Land Use Planning Commission and Maine Public Utilities Commission.
The final approval came in the form of a presidential permit issued last month from the U.S. Department of Energy, providing green light for the interconnect at the Canadian border, even as customer backlash to utility acquisitions elsewhere underscores public scrutiny.
AP1000 Refueling Outage Record showcases Westinghouse nuclear power excellence as Sanmen Unit 2 completes its first reactor refueling in 28.14 days, highlighting safety, reliability, outage optimization, and economic efficiency in China.
Key Points
It is the 28.14-day initial refueling at Sanmen Unit 2, a global benchmark achieved with Westinghouse AP1000 technology.
✅ 28.14-day first refueling at Sanmen Unit 2 sets global benchmark
✅ AP1000 design simplifies systems, improves safety and reliability
✅ Outage optimization by Westinghouse and CNNC accelerates schedules
Westinghouse Electric Company China operations today announced that Sanmen Unit 2, one of the world's first AP1000® nuclear power plants, has set a new refueling outage record in the global nuclear power industry, completing its initial outage in 28.14 days.
"Our innovative AP1000 technology allows for simplified systems and significantly reduces the amount of equipment, while improving the safety, reliability and economic efficiency of this nuclear power plant, reflecting global nuclear milestones reached recently," said Gavin Liu, president of the Westinghouse Asia Operating Plant Services Business. "We are delighted to see the first refueling outage for Sanmen Unit 2 was completed in less than 30 days. This is a great achievement for Sanmen Nuclear Power Company and further demonstrates the outstanding performance of AP1000 design."
All four units of the AP1000 nuclear power plants in China have completed their first refueling outages in the past 18 months, aligning with China's nuclear energy development momentum across the sector. The duration of each subsequent outage has fallen significantly - from 46.66 days on the first outage to 28.14 days on Sanmen Unit 2.
"During the first AP1000 refueling outage at the Sanmen site in December 2019, a Westinghouse team of experts worked side-by-side with the Sanmen outage team to partner on outage optimization, and immediately set a new standard for a first-of-a-kind outage, while major refurbishments like the Bruce refurbishment moved forward elsewhere," said Miao Yamin, chairman of CNNC Sanmen Nuclear Power Company Limited. "Lessons learned were openly exchanged between our teams on each subsequent outage, which has built to this impressive achievement."
Westinghouse provided urgent technical support on critical issues during the outage, as international programs such as Barakah Unit 1 achieved key milestones, to help ensure that work was carried out on schedule with no impact to critical path.
In addition to the four AP1000 units in China, two units are under construction at the Vogtle expansion near Waynesboro, Georgia, USA.
Separately, in the United States, a new reactor startup underscored renewed momentum in nuclear generation this year.
Ukraine Winter Energy Attacks strain the power grid as Russian missile strikes hit critical infrastructure, causing blackouts, civilian casualties, and damage in Kyiv, Kherson, and Kharkiv, underscoring air defense needs and looming cold-weather risks.
Key Points
Russian strikes on energy infrastructure cause outages, damage, and harm as Ukraine braces for freezing winter months.
✅ Power cuts reported in 400 localities; grid stability at risk.
✅ Kyiv seeks more air defenses as winter threats intensify.
Ukraine has warned that a difficult winter looms ahead after a massive Russian missile barrage targeted civilian infrastructure, killing three in the south and wounding many across the country.
Russia launched the strikes as Ukraine prepares for a third winter during Moscow's 19-month long invasion and as President Volodymyr Zelensky made his second wartime trip to Washington amid a U.S. end to grid support announcement.
"Most of the missiles were shot down. But only the majority. Not all," Zelensky said, calling for the West to provide Kyiv with more anti-missile systems to help keep the lights on this winter amid ongoing attacks.
The fresh attack came as Poland said it would honour pre-existing commitments of weapons supplies to Kyiv, a day after saying it would no longer arm its neighbour in a mounting row between the two allies.
Moscow hit cities from Rivne in western Ukraine to Kherson in the south, the capital Kyiv and cities in the centre and northeast of the country.
Kyiv also reported power cuts across the country -- in almost 400 cities, towns and villages -- as Russia targeted power plants across the grid, but said it was "too early" to tell if this was the start of a new Russian campaign against its energy sites.
Officials added that electricity reserves could limit scheduled outages if no new large-scale strikes occur.
Last winter many Ukrainians had to go without electricity and heating in freezing temperatures as Russia hit Kyiv's energy facilities.
"Difficult months are ahead: Russia will attack energy and critically important facilities," said Oleksiy Kuleba, the deputy head of Kyiv's presidential office.
Ukraine also said that it had struck a military airfield in Moscow-annexed Crimea, a claim denied by Russian-installed authorities.
'Ceilings fell down' Russia's overnight strikes were deadliest in the southern Kherson, where three people were killed.
In Kyiv's eastern Darnitsky district, frightened residents of a dormitory woke up to their rooms with shattered windows and parked cars outside completely burnt out.
Communities have also adopted new energy solutions to cope with winter blackouts, from generators to shared warming points.
Debris from a downed missile in the capital wounded seven people, including a child.
"God, god, god," Maya Pelyukh, a cleaner who lives in the building, said as she looked at her living room covered in broken glass and debris on her bed.
Her windows and door were blown away, with the 50-year-old saying she crawled out from under a door frame.
Some residents outside were still in dressing gowns as they watched emergency workers put out a fire the authorities said had spread over 400 square meters (4,300 square feet).
In the northeastern city of Kharkiv seamstresses were clearing a damaged clothing factory, with a Russian missile hitting nearby.
"The ceilings fell down. Windows were blown out. There are chunks of the road inside," Yulia Barantsova said, as she cleared a sewing machine from dust and rubble.
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.
Nova Scotia Power solar charge proposes an $8/kW monthly system access fee on net metering customers, citing grid costs. UARB review, carbon credits, rate hikes, and solar industry impacts fuel political and consumer backlash.
Key Points
A proposed $8/kW monthly grid access fee on net metered solar customers, delayed to Feb 1, 2023, pending UARB review.
✅ $8/kW monthly system access fee on net metering
✅ Delay to Feb 1, 2023 after industry and political pushback
✅ UARB review; debate over grid costs and carbon credits
Nova Scotia Power has pushed back by a year the start date of a proposed new charge for customers who generate electricity and sell it back to the grid, following days of concern from the solar industry and politicians worried that it will damage the sector.
The company applied to the Nova Scotia Utility and Review Board (UARB) last week for various changes, including a "system access charge" of $8 per kilowatt monthly on net metered installations, and the province cannot order the utility to lower rates under current law. The vast majority of the province's 4,100 net metering customers are residential customers with solar power, according to the application.
The proposed charge would have come into effect Tuesday if approved, but Nova Scotia Power said in a news release Tuesday it will change the date in its filing from Feb. 1, 2022, to Feb. 1, 2023.
"We understand that the solar industry was taken off guard," utility CEO Peter Gregg said in an interview.
"There could have been an opportunity to have more conversations in advance."
Gregg said the utility will meet with members of the solar industry over the next year to work on finding solutions that support the sector's growth, while addressing what NSP sees as an inequity in the net metering system.
NSP recognized that customers who choose solar invest a significant amount and pay for the electricity they use, but they don't pay for costs associated with accessing the electrical grid when they need energy, such as on cold winter evenings when the sun is not shining.
"I know that's hit a nerve, but it doesn't take away the fact that it is an issue," Gregg said.
He said this is an issue utilities are navigating around North America, where seasonal rate designs have sparked consumer backlash in New Brunswick, and NSP is open to hearing ideas for other models of charges or fees.
The utility's suggested system access charge closely resembles one proposed in California, which has also raised major concerns from the solar industry and been criticized by the likes of Elon Musk, and has parallels to Massachusetts solar demand charges as well.
Although the "solar profile" of Nova Scotia and California is very different, with far more solar customers in that state, and in other provinces such as Saskatchewan, NDP criticism of 8% hikes has intensified affordability debates, Gregg said the fundamental issues are the same.
For those with a typical 10-kilowatt solar system, which generates around $1,800 of electricity a year, the new charge would mean those customers would be required to pay $960 back to NSP. That would roughly double the length of time it takes for those customers to pay off their investment for the panels.
David Brushett, chair of Solar Nova Scotia, said he relayed concerns from solar installers and others in the industry to Gregg on Monday.
Brushett said the year delay is a positive first step, but he is still calling on the province to take a strong stance against the application, which has led to customers cancelling their panel installations and companies considering layoffs.
"There's still an urgency to this situation that hasn't been addressed, and we need to kind of protect the industry," he said Tuesday.
NSP's original application proposed exempting net metering customers who enrolled before Feb. 1, 2022, from the charge for 25 years after they sign up. But any benefit would be lost if those customers sold their home, and the exemption wouldn't extend to the new buyers, said Brushett.
Carbon offsets missing from equation: industry Brushett said NSP "completely ignored" the fact that it's getting free carbon offset credits from homeowners who use solar energy under the provincial cap and trade program.
If the net metering system continues as is, NSP has said non-solar customers would pay about $55 million between now and 2030. That number assumes about 2,000 people sign up for net metering each year over the next nine years.
When asked whether those carbon emission credits were factored into the calculations for the proposed charge, Gregg said, "I don't believe in the current structure it is, but it's something that certainly we'd be open to hearing about."
Brushett said his group is finalizing a legal response to NSP's proposal and has already filed an official complaint against the company with the UARB.
Base charge on actual electrical output: customer At least one shareholder in NSP parent company Emera is considering selling his shares in response to the application.
Joe Hood, a shareholder from Middle Sackville, said the proposed charge won't apply to his existing 11.16-kilowatt solar system, but if it did, it would cost him $1,071 a year.
"I am offended that a company I would invest in would do this to the solar industry in Nova Scotia," he said.
According to his meter, Hood said he pushed 9,600 kilowatt hours of solar electricity to the grid last year— some only for a brief period, and all of which was used by his home by the end of the year.
Under the proposed charge, someone with one solar panel who goes away on vacation in the summer would push all their electricity to the grid, and be charged far less than someone with 10 panels who has used all their own power and hasn't pushed anything.
"Nova Scotia Power's argument is that it's an issue with the grid. Well, then it should be based on what touches the grid," Hood said.
Far from actually making the system fair for everyone, Hood said this charge places solar only in the hands of the super-rich or NSP, with projects like its community solar gardens in Amherst, N.S.
Green Party suggests legislation update Nova Scotia's Green Party also said Tuesday that Gregg's arguments of fairness are misleading, echoing earlier premier opposition to a 14% hike on rates.
The party is calling for an update to the Electricity Act that would "prevent penalizing any activity that helps Nova Scotia reach its emissions target," aligning with calls to make the electricity system more accountable to residents.
In its application, NSP has also asked to increase electricity rates for residential customers by at least 10 per cent over the next three years, amid debate that culminated in a 14% rate hike approval by regulators.
The company wants to maintain its nine per cent rate of return.
NSP expects to earn $153 million this year, $192 million in 2023, and $213 million in 2024 from its rate of return.
