The Maine Power Reliability Program (MPRP) is an essential investment in our state's electricity transmission grid, which brings power from generation plants to cities and towns.

Central Maine Power's proposal for this reliability program follows an exhaustive study of the company's grid and its links to systems in Canada and the other New England states. That work showed the need for immediate, major investments to improve grid reliability based on the loads that flow across the system today. CMP's plan will bring Maine into compliance with mandatory federal standards for grid reliability and reduce economic and social risks of grid failures in the future.

Maine's bulk power grid dates from the late 1960s when coal, nuclear, oil and large hydro plants supplied most of the region's electricity. The grid has served us well, but 40 years forward, Maine is a different place.

Our electricity usage has doubled. Population has increased by nearly one-third, and people and jobs have moved south and toward the coast.

Our sources of electricity have changed as well, and the technology of energy generation is evolving in ways that will make us more dependent on the next grid we build.

Today's emerging renewable resources, such as wind, wave, tidal and solar power, depend on highly variable weather conditions, and they often require sites in remote mountains or where the ocean's energy can be tapped.

That these resources are so variable and scattered does not make them less vital to our future, but it does require a transmission network capable of matching rapid and major variations in production with sometimes-distant customers. A stronger, modern grid is an essential investment for the renewable energy development that Maine seeks.

Maine is not an electrical island. Our grid is linked with neighboring systems on all sides for access to electricity markets and system reliability. For example, Maine actually imports electricity from other New England states and Canada about 30 percent of the time.

Also, the reliability of our grid affects all the other New England states, so electricity customers in all six states will share the cost of the MPRP in proportion to their share of the regional load. The MPRP will cost $1.5 billion, but Maine's share will be only 8 percent of that because we use just 8 percent of the electricity carried on the New England grid. The other five New England states will pay the other 92 percent, or about $1.38 billion.

The MPRP will also provide a needed boost for Maine's economy. It will create over 3,300 jobs during the peak years of construction and bring nearly $289 million into our state's economy by the time it is built.

A reliable supply of electricity is a necessity and expectation in a modern economy. Looking back, Maine has benefited immensely from the investments that were made 40 years ago, and many of our hopes for a stronger economy, cleaner environment, and more secure energy future will depend on the investments we are about to make. The MPRP is the right choice for Maine.

GridSolar partners were invited to state their case for their project. Instead, they attacked the Maine Power Reliability Program (MPRP). GridSolar's public filings are already light on facts. Their unwillingness to provide substantive information to readers betrays their own lack of confidence in the merits of their proposal.

GridSolar is hugely more expensive to Maine customers because they will pay 100 percent of the costs. For the MPRP, customers will only pay 8 percent of the costs, and residents in other New England states will pay the rest. GridSolar claims that it would sell energy at 3 cents per kWh for 20 years but neglects to mention that it would do so only if CMP's customers pay more than a billion dollars of the project's capital costs.

GridSolar will require 10,000 acres of land to build the solar plantations that it proposes. GridSolar criticizes CMP for use of eminent domain authority, but this attack is simply another example of GridSolar's indifference to the facts.

Central Maine Power has not used its eminent domain authority a single time to secure more than 400 parcels to date. In fact, GridSolar has requested eminent domain authority from the Maine PUC because it knows that it can't guarantee acquisition of 10,000 acres without it. CMP welcomes the addition of renewable resources to Maine. MPRP is vital to make that happen.

To suggest, as GridSolar does, that solar power can serve as a replacement for MPRP is a little like saying that once you have hybrid cars you don't need roads. Maine needs a realistic plan to meet our goals for reliable power, renewable resources and energy security.

Share of coal in UK's electricity system falls to record lows

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

 

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

 

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

Annual U.S. coal-fired electricity generation will increase for the first time since 2014

U.S. coal-fired generation 2021 rose as higher natural gas prices, stable coal costs, and a recovering power sector shifted the generation mix; capacity factors rebounded despite low coal stocks and ongoing plant retirements.

 

Key Points

Coal output rose 22% on high gas prices and higher capacity factors; a 5% decline is expected in 2022.

✅ Natural gas delivered cost averaged $4.93/MMBtu, more than double 2020

✅ Coal capacity factor rose to ~51% from 40% in 2020

✅ 2022 coal generation forecast to fall about 5%

 

We expect 22% more U.S. coal-fired generation in 2021 than in 2020, according to our latest Short-Term Energy Outlook (STEO). The U.S. electric power sector has been generating more electricity from coal-fired power plants this year as a result of significantly higher natural gas prices and relatively stable coal prices, even as non-fossil sources reached 40% of total generation. This year, 2021, will yield the first year-over-year increase in coal generation in the United States since 2014, highlighted by a January power generation jump earlier in the year.

Coal and natural gas have been the two largest sources of electricity generation in the United States. In many areas of the country, these two fuels compete to supply electricity based on their relative costs and sensitivity to policies and gas prices as well. U.S. natural gas prices have been more volatile than coal prices, so the cost of natural gas often determines the relative share of generation provided by natural gas and coal.

Because natural gas-fired power plants convert fuel to electricity more efficiently than coal-fired plants, record natural gas generation has at times underscored that advantage, and natural gas-fired generation can have an economic advantage even if natural gas prices are slightly higher than coal prices. Between 2015 and 2020, the cost of natural gas delivered to electric generators remained relatively low and stable. This year, however, natural gas prices have been much higher than in recent years. The year-to-date delivered cost of natural gas to U.S. power plants has averaged $4.93 per million British thermal units (Btu), more than double last year’s price.

The overall decline in electricity demand in 2020 and record-low natural gas prices led coal plants to significantly reduce the percentage of time that they generated power. In 2020, the utilization rate (known as the capacity factor) of U.S. coal-fired generators averaged 40%. Before 2010, coal capacity factors routinely averaged 70% or more. This year’s higher natural gas prices have increased the average coal capacity factor to about 51%, which is almost the 2018 average, a year when wind and solar reached 10% nationally.

Although rising natural gas prices have resulted in more U.S. coal-fired generation than last year, this increase in coal generation will most likely not continue as solar and wind expand in the generation mix. The electric power sector has retired about 30% of its generating capacity at coal plants since 2010, and no new coal-fired capacity has come online in the United States since 2013. In addition, coal stocks at U.S. power plants are relatively low, and production at operating coal mines has not been increasing as rapidly as the recent increase in coal demand. For 2022, we forecast that U.S. coal-fired generation will decline about 5% in response to continuing retirements of generating capacity at coal power plants and slightly lower natural gas prices.

Wyoming wind boost for US utility

Black Hills Energy Corriedale Wind Farm Expansion earns regulatory approval in Wyoming, boosting capacity to over 52MW near Cheyenne with five turbines, supporting Renewable Ready customers and wind power goals under PUC and PSC oversight.

 

Key Points

An approved Wyoming wind project upgrade to over 52MW, adding five turbines to serve Renewable Ready customers.

✅ Adds 12.5MW via five new wind turbines near Cheyenne

✅ Cost increases to $79m; prior estimate $57m

✅ Approved by SD PUC after Wyoming PSC review

 

US company Black Hills Energy has received regulatory approval to increase the size of its Corriedale wind farm in Wyoming, where Wyoming wind exports to California are advancing, to over 52MW from 40MW previously.

The South Dakota Public Utilities Commission approved the additional 12.5MW capacity after the Wyoming Public Service Commission determined the boost was within commission rules, as federal initiatives like DOE wind energy awards continue to support the sector.

Black Hills Energy will install five additional turbines, raising the project cost to $79m from $57m, amid growing heartland wind investment across the region.
Corriedale will be built near Cheyenne and is expected to be placed in service in late 2020.

Similar market momentum is seen in Canada, where a Warren Buffett-linked Alberta wind farm is planned to expand capacity across the region.

Black Hills said that during the initial subscription period for its Renewable Ready program, applications of interest from eligible commercial, industrial and governmental agency customers were received in excess of the program's 40MW, underscoring the view that more energy sources can make stronger projects.

Black Hills Corporations chief executive and president Linden Evans said: “We are pleased with the opportunity to expand our Renewable Ready program, allowing us to meet our customers’ interest in renewable wind energy, which co-op members increasingly support.

“This innovative program expands our clean energy portfolio while meeting our customers’ evolving needs, particularly around cleaner and more sustainable energy, as projects like new energy generation coming online demonstrate.”

Iran Says Deals to Rehabilitate, Develop Iraq Power Grid Finalized

Iran-Iraq Power Grid Deals reinforce electricity and natural gas ties, upgrading transmission in Karbala and Najaf, repairing transformers, easing sanctions bottlenecks, and weighing GCC interconnection to diversify supply and reduce distribution losses across Iraq.

 

Key Points

Agreements to rehabilitate Iraq's grid, cut losses, and secure power via Iranian gas, electricity, and upgrades.

✅ Reduce distribution losses in Karbala and Najaf

✅ Repair and replace damaged distribution transformers

✅ Coordinate payments to TAVANIR amid US sanctions

 

Iran and Iraq have finalized two deals to rehabilitate and develop the power grid of Iraq, while Iran is upgrading thermal plants to combined cycle at home to save energy, IRNA cited the Iranian Energy Minister Reza Ardakanian.

Ardakanian met his Iraqi counterpart Majid Mahdi Hantoush in Tehran on Tuesday evening for talks on further energy cooperation on the sidelines of Prime Minister Mustafa al-Kadhimi’s trip to the Islamic Republic on his first foreign visit.

“It was decided that the contracts related to reducing losses on the electricity distribution network in the provinces of Karbala and Najaf, as well as the contract for repairing Iraq’s distribution transformers would be finalized and signed,” the Iranian minister said.

Iraq relies on Iran for natural gas that generates as much as 45 percent of its electricity, with Iran supplying 40% of Iraq’s power according to sector reports. Iran transmits another 1,200 MW directly, and has regional power hub plans as well, making itself an indispensable energy source for its Arab neighbor, but the United States is trying to pry Baghdad away from Tehran’s orbit.

The US has been enlisting its companies and allies such as Saudi Arabia to replace Iran as Iraq’s source of energy.

Iran’s money from exports of gas and electricity has accumulated in bank accounts in Iraq, because US sanctions are preventing Tehran from repatriating it.

In January, an official said the sanctions were giving Iran a run for five billion dollars, “sedimenting” at the Central Bank of Iraq, because Tehran could not access it.

Ardakanian said the issue was brought up in the discussions on Tuesday and it was agreed that “the payment of part of TAVANIR (Iran Power Generation and Transmission Company)’s claims will start from the end of July”.

The US administration is pushing for a deal between Washington, Baghdad and six Persian Gulf states to connect Iraq’s nationwide power grid to that of the Persian Gulf Cooperation Council, while Uzbekistan looks to export power to Afghanistan as regional linkages expand.

The US State Department said in a statement last Thursday that the six countries that make up the (Persian) Gulf Cooperation Council Interconnection Authority (GCCIA) — Saudi Arabia, Kuwait, Bahrain, Qatar, Oman and the UAE — had affirmed their shared support for the project to supply electricity to Iraq.

Iraq needs more than 23,000 MW of electricity to meet its domestic demand, and is exploring nuclear power plans to tackle shortages, but years of war following the 2003 US invasion have left its power infrastructure in tatters and a deficit of some 7,000 MW.

In the past, officials in Baghdad have said there is no easy substitute to imports from Iran because it will take years to adequately build up Iraq’s energy infrastructure, and meeting summer electricity needs remains a persistent challenge.

They have said American demand acknowledges neither Iraq’s energy needs nor the complex relations between Baghdad and Tehran.

In addition to natural gas and electricity, Iraq imports a wide range of goods from Iran including food, agricultural products, home appliances, and air conditioners.

On Tuesday, the Iraqi prime minister said during a joint news conference with Iranian President Hassan Rouhani that the purpose of his trip to Tehran was to strengthen historical ties between the two countries, especially in light of the challenges they faced as a result of the coronavirus outbreak and the fall of oil prices.

“In the face of such challenges, we need coordination between the two countries in a way that serves the interests of Iran and Iraq.”

Both Iran and Iraq, Kadhimi said, suffer from economic problems, adding the two countries need comprehensive and inclusive cooperation to overcome them.

Kadhimi said Iran-Iraq relations are not merely due to the geographical location of the two countries and their 1,450-km border, adding the ties are based on religion and culture and rooted in history.

“I am reiterating to my brothers in the Islamic Republic of Iran that the Iraqi nation is eager to have excellent relations with the Islamic Republic of Iran based on the principle of non-interference in the internal affairs of the two countries.”

Kadhimi said Iran and Iraq fought against terrorism and Takfiri groups together, and the Islamic Republic of Iran was one of the first countries to stand by Iraq.

“We will not forget this. That is why Iraq has stood with Iran to help it overcome economic challenges and turned to a big market for trade with Iran,” he said.

“We seek stability in Iraq and our philosophy and view of Iran is that we consider Iran a stable, strong, prosperous and progressive country, and this fact is in the interest of Iraq and the territorial integrity of the region,” he added.

According to Kadhimi, the two sides discussed implementing agreements between them, including connecting their railway through Khorramshahr in Iran and Basra in Iraq, adding he was very confident the agreements would be implemented soon.

Iraq’s delegation included the ministers of foreign affairs, finance, health, and planning, as well as Kadhimi’s national security adviser, some of whom also met their Iranian counterparts.

Last year, Iran’s exports to Iraq amounted to nearly $9 billion, IRNA reported. It said the two nations will discuss increasing that amount to $20 billion.

“The two governments’ will is to expand bilateral trade to $20 billion,” Rouhani said after an hour-long meeting with the Iraqi prime minister.

Africa must quadruple power investment to supply electricity for all, IEA says

Africa Energy Investment must quadruple, says IEA, to deliver electricity access via grids, mini-grids, and stand-alone solar PV, wind, hydropower, natural gas, and geothermal, targeting $120 billion annually and 2.5% of GDP.

 

Key Points

Africa Energy Investment funds reliable, low-carbon electricity via grids, mini-grids, and renewables.

✅ Requires about $120B per year, or 2.5% of GDP

✅ Mix: grids, mini-grids, stand-alone solar PV and wind

✅ Targets reliability, economic growth, and electricity access

 

African countries will need to quadruple their rate of investment in their power sectors for the next two decades to bring reliable electricity to all Africans, as outlined in the IEA’s path to universal access analysis, an International Energy Agency (IEA) study published on Friday said.

If African countries continue on their policy trajectories, 530 million Africans will still lack electricity in 2030, the IEA report said. It said bringing reliable electricity to all Africans would require annual investment of around $120 billion and a global push for clean, affordable power to mobilize solutions.

“We’re talking about 2.5% of GDP that should go into the power sector,” Laura Cozzi, the IEA’s Chief Energy Modeller, told journalists ahead of the report’s launch. “India’s done it over the past 20 years. China has done it, with solar PV growth outpacing any other fuel, too. So it’s something that is doable.”

Taking advantage of technological advances and optimizing natural resources, as highlighted in a renewables roadmap, could help Africa’s economy grow four-fold by 2040 while requiring just 50% more energy, the agency said.

Africa’s population is currently growing at more than twice the global average rate. By 2040, it will be home to more than 2 billion people. Its cities are forecast to expand by 580 million people, a historically unprecedented pace of urbanization.

While that growth will lead to economic expansion, it will pile pressure on power sectors that have already failed to keep up with demand, with the sub-Saharan electricity challenge intensifying across the region. Nearly half of Africans - around 600 million people - do not have access to electricity. Last year, Africa accounted for nearly 70% of the global population lacking power, a proportion that has almost doubled since 2000, the IEA found.

Some 80% of companies in sub-Saharan Africa suffered frequent power disruptions in 2018, leading to financial losses that curbed economic growth.

The IEA recommended changing how power is distributed, with mini-grids and stand-alone systems like household solar playing a larger role in complementing traditional grids as targeted efforts to accelerate access funding gain momentum.

According to IEA Executive Director Fatih Birol, with the right government policies and energy strategies, Africa has an opportunity to pursue a less carbon-intensive development path than other regions.

“To achieve this, it has to take advantage of the huge potential that solar, wind, hydropower, natural gas and energy efficiency offer,” he said.

Despite possessing the world’s greatest solar potential, Africa boasts just 5 gigawatts of solar photovoltaics (PV), or less than 1% of global installed capacity, a slow green transition that underscores the scale of the challenge, the report stated.

To meet demand, African nations should add nearly 15 gigawatts of PV each year through 2040. Wind power should also expand rapidly, particularly in Ethiopia, Kenya, Senegal and South Africa. And Kenya should develop its geothermal resources.

British Columbians can access more in EV charger rebates

B.C. EV Charging Rebates boost CleanBC incentives as NRCan and ZEVIP funding covers up to 75% of Level 2 and DC fast-charger purchase and installation costs for homes, workplaces, condos, apartments, and fleet operators.

 

Key Points

Incentives in B.C. cover up to 75% of Level 2 and DC fast charger costs for homes, workplaces, and fleets.

✅ Up to 75% back; Level 2 max $5,000; DC fast max $75,000 for fleets.

✅ Eligible sites: homes, workplaces, condos, apartments, fleet depots.

✅ Funded by CleanBC with NRCan ZEVIP; time-limited top-up.

 

The Province and Natural Resources Canada (NRCan) are making it more affordable for people to install electric vehicle (EV) charging stations in their homes, businesses and communities, as EV demand ramps up across the province.

B.C. residents, businesses and municipalities can receive higher rebates for EV charging stations through the CleanBC Go Electric EV Charger Rebate and Fleets programs. For a limited time, funding will cover as much as 75% of eligible purchase and installation costs for EV charging stations, which is an increase from the previous 50% coverage.

“With electric vehicles representing 13% of all new light-duty vehicles sold in B.C. last year, our province has the strongest adoption rate of electric vehicles in Canada. We’re positioning ourselves to become leaders in the EV industry,” said Bruce Ralston, B.C.’s Minister of Energy, Mines and Low Carbon Innovation. “We’re working with our federal partners to increase rebates for home, workplace and fleet charging, and making it easier and more affordable for people to make the switch to electric vehicles.”

With a $2-million investment through NRCan’s Zero-Emission Vehicle Infrastructure Program (ZEVIP) to top up the Province’s EV Charger Rebate program, workplaces, condominiums and apartments can get a rebate for a Level 2 charging station for as much as 75% of purchase and installation costs to a maximum of $5,000. As many as 360 EV chargers will be installed through the program.

“We’re making electric vehicles more affordable and charging more accessible where Canadians live, work and play,” said Jonathan Wilkinson, federal Minister of Natural Resources. “Investing in more EV chargers, like the ones announced today in British Columbia, will put more Canadians in the driver’s seat on the road to a net-zero future and help achieve our climate goals.”

Through the CleanBC Go Electric Fleets program and in support of B.C. businesses that own and operate fleet vehicles, NRCan has invested $1.54 million through ZEVIP to top up rebates. Fleet operators can get combined rebates from NRCan and the Province for a Level 2 charging station as much as 75% to a maximum of $5,000 of purchase and installation costs, and 75% to a maximum of $75,000 for a direct-current, fast-charging station. As many as 450 EV chargers will be installed through the program.

CleanBC is a pathway to a more prosperous, balanced and sustainable future. It supports government’s commitment to climate action to meet B.C.’s emission targets and build a cleaner, stronger economy.

Quick Facts:

  • A direct-current fast charger on the BC Electric Highway allows an EV to get 100-300 kilometres of range from 30 minutes of charging.
  • Faster chargers, which give more range in less time, are coming out every year.
  • A Level 2 charger allows an EV to get approximately 30 kilometres of range per hour of charging.
  • It uses approximately the same voltage as a clothes dryer and is usually installed in homes, workplaces or for fleets to get a faster charge than a regular outlet, or in public places where people might park for a longer time.
  • A key CleanBC action is to strengthen the Zero-Emission Vehicles Act to require light-duty vehicle sales to be 26% zero-emission vehicles (ZEVs) by 2026, 90% by 2030 and 100% by 2035, five years ahead of the original target.
  • At the end of 2021, B.C. had more than 3,000 public EV charging stations and almost 80,000 registered ZEVs.
