It takes energy to maintain energy from small wind farms.

That was the conclusion of Idaho Power's recent study on the impact of wind power.

Among other findings, the Operational Impact report said that small wind farms - those which produce 10 megawatts or fewer - require the assistance of hydroelectric power to compensate for generating fluctuations caused by changes in wind speed.

Idaho Power uses its hydroelectric sources to provide additional energy when small wind farms are unable to stay at predetermined power levels.

The report estimates that it costs Idaho Power $10.72 per megawatt hour to offset such fluctuations. The utility wants wind farm operators to pay that expense.

Wind farm developers are paid an average of $64 per megawatt hour for farms built in 2008.

Jeff Beaman, director of corporate communications for Idaho Power, said the cost is an average of what it costs Idaho Power to adjust flows at dams for backup energy.

"The dams are already being fully utilized to produce energy for the benefit of customers," Beaman said. "This firming (backup) requirement places another demand on the hydro system."

According to the report, hydroelectric generation is near capacity in Idaho. If additional wind farms are added to the system, the state would have to consider alternatives to hydro such as coal- fired power plants in order to provide backup electricity to wind farms.

Beaman said the report is the first step in what will be a lengthy discussion.

"This is the beginning of a continued learning process of how wind will be integrated into an energy generating system," Beaman said. "Idaho Power recommends that the (Idaho Public Utilities Commission) sanction a workshop where all the interested parties put this study under the microscope and work through it together."

Manitoba's electrical demand could double in next 20 years: report

Manitoba Hydro Integrated Resource Plan outlines electrification-driven demand growth, clean electricity needs, wind generation, energy efficiency, hydropower strengths, and net-zero policy impacts, guiding investments to expand capacity and decarbonize Manitoba's grid.

 

Key Points

Manitoba Hydro IRP forecasting 2.5x demand, clean power needs, and capacity additions via wind and energy efficiency.

✅ Projects electricity demand could more than double within 20 years.

✅ Leverages 97% hydro supply; adds wind generation and efficiency.

✅ Positions for net-zero, electrification, and new capacity by the 2030s.

 

Electrical demand in Manitoba could more than double in the next 20 years, a trend echoed by BC Hydro's call for power in response to electrification, according to a new report from Manitoba Hydro.

On Tuesday, the Crown corporation released its first-ever Integrated Resource Plan (IRP), which not only predicts a significant increase in electrical demand, but also that new sources of energy, and a potential need for new power generation, could be needed in the next decade.

“Right now, what [our customers] are telling us, with the climate change objectives, with federal policy, provincial policies, is they see using electricity much more in the future than they do today,” said president and CEO of Manitoba Hydro Jay Grewal.

“And our current, where we’re at now, our customers have told us through all this consultation and engagement over the last two years, they’re going to want and need more than 2.5 times the electricity than we have in the province today.”

The IRP indicates that the move towards low or no-carbon energy sources will accelerate the need for clean electricity, which will require significant investments, including new turbine investments to expand capacity. Some of the clean energy measures Hydro is looking at for the future include wind generation and energy efficiency.

The report also found that Manitoba is in a good position as it prepares for the future due to its hydroelectric system, which delivers around 97 per cent of the yearly electricity. However, the province’s existing supply is limited, and vulnerable to Western Canada drought impacts on hydropower, so other electrical energy sources will be needed.

“Something Manitobans may not realize is, we are in such a privileged province, because 97 per cent of the electricity produced in Manitoba today is clean energy and net zero,” Grewal said.

Manitoba also supplies power to neighbouring utilities, with a SaskPower purchase agreement to buy more electricity under an expanded deal.

The IRP is the result of a two-year development process that involved multiple rounds of engagement with customers and other interested parties. The IRP is not a development plan, but it arrives as Hydro warns it can't service new energy-intensive customers under current capacity, and it outlines how Manitoba Hydro will monitor, prepare and respond to the changes in the energy landscape.

“We spoke with over 15,000 of our customers, whether they’re residential, commercial, industrial, industry associations, regulators, government – across the board, we talked with our customers,” said Grewal.

“And what we did was through this work, we understood what our customers are anticipating using electricity for going forward.

China to build 525-MW hydropower station on Yangtze tributary

Baima Hydropower Station advances China renewable energy on the Wujiang River, a Yangtze tributary in Chongqing; a 525 MW cascade project approved by NDRC, delivering 1.76 billion kWh and improving river shipping.

 

Key Points

An NDRC-approved 525 MW project on Chongqing's Wujiang River, producing 1.76 billion kWh and improving navigation.

✅ 10.2 billion yuan investment; final cascade plant on Wujiang in Chongqing

✅ Expected output: 1.76 billion kWh; capacity 525 MW; NDRC approval

✅ Improves river shipping; relocation of 5,000 residents in Wulong

 

China plans to build a 525-MW hydropower station on the Wujiang River, a tributary of the Yangtze River, in Southwest China's Chongqing municipality, aligning with projects like the Lawa hydropower station elsewhere in the Yangtze basin.

The Baima project, the last of a cascade of hydropower stations on the section of the Wujiang River in Chongqing, has gotten the green light from the National Development and Reform Commission, China's state planning agency, even as some independent power projects elsewhere face uncertainty, such as the Siwash Creek project in British Columbia, the Chongqing Municipal Commission of Development and Reform said Monday.

The project, in Baima township of Wulong district, is expected to involve an investment of 10.2 billion yuan ($1.6 billion), as China explores compressed air generation to bolster grid flexibility, it said.

With a power-generating capacity of 525 MW, it is expected to generate 1.76 billion kwh of electricity a year, supporting efforts to reduce coal power production nationwide, and help improve the shipping service along the Wujiang River.

More than 5,000 local residents will be relocated to make room for the project, which forms part of a broader energy mix alongside advances in nuclear energy in China.

India Electricity Prices are Spiking

India spot electricity prices surged on Q3 demand, lifting power tariffs in the spot market as discoms scrambled for supply; Sembcorp SGPL boosted PLF and short-term PPA realizations, benefiting from INR per kWh peaks.

 

Key Points

India spot electricity prices hit Q3 records amid demand spikes, lifting tariffs and aiding Sembcorp SGPL via PLF gains.

✅ Record 10.6 cents/kWh average; 15-minute peak 20.7 cents/kWh

✅ SGPL shifted output to short-term PPA at 7.3 cents/kWh

✅ PLF ramped above 90%, cutting core losses by 30-40%

 

Electricity prices in India, now the third-largest electricity producer globally, bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3.

A jolt in Indian spot electricity prices could save Sembcorp Industries' Indian business from further losses, even though demand has occasionally slumped in recent years, UOB Kay Hian said.

The firm said spot electricity prices in India bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3 and even hit a 15-minute peak of 20.7 cents/kWh (9.9/kWh). The spike was due to a power supply crunch on higher electricity demand from power distribution companies, alongside higher imported coal volumes as domestic supplies shrank.

As an effect, Sembcorp Industries' Sembcorp Gayatri Power Limited's (SGPL) losses of $26m in Q1 and $29m in Q2 could narrow down by as much as 30-40%.

On a net basis, SGPL will recognise a significantly higher electricity tariff in 3Q17. By tactically shutting down its Unit #3 for maintenance, Unit #4 effectively had its generation contracted out at the higher short-term PPA tariff of around 7.3 cents/kWh (Rs3.5/kWh).

SGPL also capitalised on the price spike in 3Q17 as it ramped up its plant load factor (PLF) to more than 90%.

“On the back of this, coupled with the effects of reduced finance costs, we expect SGPL’s 3Q17 quarterly core loss to shrink by 30-40% from previous quarters,” UOB Kay Hian said.

Whilst electricity prices have corrected to 7.1 cents/kWh (INR3.4/kWh), the firm said it could still remain elevated on structural factors, even as coal and electricity shortages ease nationwide.

Sembcorp Industries' India operations brought in a robust performance for Q3. PLF for Thermal Powertech Corporation India Limited (TPCIL) hit 91%, whilst it reached 73% for SGPL, echoing the broader trend of thermal PLF up across the sector.

Venezuela: Electricity Recovery Continues as US Withdraws Diplomatic Staff

Venezuela Power Outage cripples the national grid after a massive blackout; alleged cyber attacks at Guri Dam and Caracas, damaged transmission lines, CORPOELEC restoration, looting, water shortages, and sanctions pressure compound recovery.

 

Key Points

A March 2019 blackout crippling Venezuela's grid amid alleged cyber attacks, equipment failures, and slow restoration.

✅ Power restored partially after 96 hours across all states

✅ Alleged cyber attacks at Guri Dam and Caracas systems

✅ CORPOELEC urges reduced load during grid stabilization

 

Venezuelan authorities continue working to bring back online the electric grid following a massive outage that started on Thursday, March 7.

According to on-the-ground testimonies and official sources, power finally began to reach Venezuela’s western states, including Merida and Zulia, on Monday night, around 96 hours after the blackout started. Electricity has now been restored at least in some areas of every state, with authorities urging citizens, as seen in Ukraine's efforts to keep lights on during crisis, to avoid using heavy usage devices while efforts to restore the whole grid continue.

President Nicolas Maduro gave a televised address on Tuesday evening, offering more details about the alleged attack against the country’s electrical infrastructure. According to Maduro, both the computerized system in the Guri Dam, on Thursday afternoon, and the central electrical “brain” in Caracas, on Saturday morning, suffered cyber attacks, while recovery was delayed by physical attacks against transmission lines and electrical substations, a pattern seen in power outages in western Ukraine as well.

“The recovery has been a miracle by CORPOELEC (electricity) workers” he said, vowing that a “battle” had been won.

Maduro claimed that the attacks were directed from Chicago and Houston and that more evidence would be presented soon. The Venezuelan president had announced on Monday that two arrests were made in connection to alleged acts of sabotage against the communications system in the Guri Dam.

Venezuela’s electrical grid has suffered from poor maintenance and sabotage in recent years, with infrastructure strained by under-investment and Washington’s economic sanctions further compounding difficulties, with parallels to electricity inequality in California highlighting broader systemic challenges, though causes differ.

The extended power outage saw episodes of lootings take place, especially in the Zulia capital of Maracaibo. Food warehouses, supermarkets and a shopping mall were targeted according to reports and footage on social media.

Isolated episodes of protests and lootings were also reported in other cities, including some sectors of Caracas. A video spread on social media appeared to show a violent confrontation in the eastern city of Maturin in which a National Guardsman was shot dead.

While electricity has been gradually restored, public transportation and other services have yet to be reactivated, a contrast with U.S. grid resilience during COVID-19 where power systems remained stable, with the government suspending work and school activities until Wednesday.

In Caracas, attention has now turned to water. Shortages started to be felt after the water pumping system in the nearby Tuy valley was shut down amid the electricity blackout, underscoring that electricity is civilization in conflict zones, as interdependent systems cascade. Authorities announced on Tuesday afternoon that the system was due to resume supplying water to the capital metropolitan region.

Some communities protested the lack of water on Monday and long queues formed at water distribution points, with local authorities looking to send water tanks to supply communities and guarantee the normal functioning of hospitals.

The Venezuelan government has yet to release any information concerning casualties in hospitals, with NGO Doctors for Health reporting 24 dead as of Monday night following alleged contact with multiple hospitals. Higher figures, including claims of 80 newborns dead in Maracaibo, have been denied by local sources.

Self-proclaimed “Interim President” Juan Guaido has blamed the electricity crisis on government mismanagement and corruption, dismissing the government’s cyber attack thesis on the grounds that the system is analog, and attributing the national outage to a lack of qualified personnel needed to reactivate the grid. However, these claims have been called into question by people with knowledge of the system.

Guaido called for street protests on Tuesday afternoon which saw small groups momentarily take to streets in Caracas and other cities, or banging pots and pans from windows.

The opposition-controlled National Assembly, which has been in contempt of court since 2016, approved a decree on Monday declaring a state of “national alarm,” blaming the government for the current crisis and issuing instructions for public officials and security forces.

Likewise on Tuesday, Venezuelan Attorney General Tarek William Saab announced that an investigation was being opened against Guaido regarding his alleged responsibility for the recent power outage. Saab explained that this investigation would add to the previous one, opened on January 29, as well as determine responsibilities in instigating violence.

City officials take clean energy message to Georgia Power, PSC

Georgia Cities Clean Energy IRP Coalition unites Savannah, Atlanta, Decatur, and Athens-Clarke to shape Georgia Power's Integrated Resource Plan, accelerating renewables, energy efficiency, community solar, and coal retirements through Georgia Public Service Commission hearings.

 

Key Points

Georgia cities working to steer Georgia Power's IRP toward renewables, energy efficiency, and community solar.

✅ Targets coal retirements and doubling renewables by 2035

✅ Advocates data access, transparency, and energy efficiency

✅ Seeks affordable community solar options for low-income customers

 

Savannah is among several Georgia cities that have led the charge forward in recent years to push for clean energy. Now, several of the state's largest municipalities are banding together to demand action from Georgia's largest energy provider.

Hearings regarding Georgia Power's Integrated Resource Plan (IRP) happen every three years, but this year for the first time the cities of Savannah, Decatur, Atlanta and Athens-Clarke and DeKalb counties were at the table.

"It's pretty unprecedented. It's such an important opportunity to get to represent ourselves and our citizens," said City of Savannah Energy Analyst Alicia Brown, the Savannah representative for the Georgia Coalition for Local Governments.

The IRP, which essentially maps out how the company will use its various forms of energy over the next 20 years was filed with the Georgia Public Service Commission (GPSC) in January, the 200-page IRP outlines Georgia Power's plans to shutter nearly all Georgia Power-controlled coal units, similar to Tucson Electric Power's coal exit timelines elsewhere, which could begin later this year.

The company is also planning to double its renewable energy generation by 2035. The IRP also outlines plans for several programs, including an Income-Qualified Community Solar Pilot, reflecting momentum for community energy programs in other states as well.

During the hearings the coalition, alongside the other groups, had the ability to question Georgia Power officials about the plan to include the proposed increase per kilowatt for the company's Simple Solar program, Behind-the-Meter Solar program study and various other components, amid debates over solar strategy in the South that could impact lower income customers.

"The established and open IRP process is central to effective, long-term energy planning in Georgia and is part of our commitment to 2.7 million customers to deliver clean, safe, reliable and affordable energy. In continuing our longstanding relationship with the City of Savannah, we welcome their interest and participation in the IRP process," John Kraft, Georgia Power spokesman said in an email.

Brown said the coalition's areas of interest fall into three categories: energy efficiency and demand response, data access and transparency and renewable energy for citizens as well as the governments in the coalition.

"We have these renewable goals and just the way the current regulations are set, the way the current laws are on the books, and developments like consumer choice in California show how policy shifts can reshape utility markets, it's very challenging for us to meet those renewable energy goals without Georgia Power setting up programs that are workable for us," she said.

The city of Savannah is already taking action locally to reduce carbon emissions and move toward clean and renewable energy through the 100% Savannah Clean Energy Plan, which was adopted by Savannah City Council in December.

The plan aims to achieve 100% renewable electricity community-wide by 2035 and 100% renewable energy for all energy needs by 2050.

Council previously approved the 100% Clean Energy Resolution needed to develop the plan in March 2020, making Savannah the fifth city in the state to pledge to pursue a lower carbon future to fight climate change.

The final plan includes 45 strategies that fall into five categories: energy efficiency; renewable energy; transportation and mobility; community and economic development; and education and engagement.

Brown said the education and engagement component is central to the plan, but the pandemic has hindered community education and awareness efforts, and utilities have warned customers about pandemic-related scams that complicate outreach, something the city hopes to catapult in the coming weeks.

"With the 100% Savannah resolution passing right before the pandemic, we haven't had as many opportunities to raise awareness about the initiative and to educate the public about clean energy as we would like. This transition will present a lot of opportunities for our communities, but only if people know that they are there to be taken," she said.

"... We also want to engage the community so that they feel like they are developing this vision for a healthy, prosperous, clean community alongside us. It's not just us telling them, 'we're going to have a clean energy future and it's going to look like this,' but really helping them to develop and realize a collective vision for what 100% Savannah should be."

The final round of IRP hearings are scheduled for next month. Those hearings will allow the coalition and other groups to put witnesses on the stand who will make the case for why Georgia Power's IRP should be different, Brown said.

In June, Georgia Power, following a June bill reduction for customers, will have a chance to offer rebuttal testimony and will again be subject to cross examination. Shortly after those hearings, the parties will join together for the settlement process, a sort of compromise on the plan that the commission will vote on toward the beginning of July.

California's Next Electricity Headache Is a Looming Shortage

California Electricity Reserve Mandate requires 3.3 GW of new capacity to bolster grid reliability amid solar power volatility, peak demand, and wildfire-driven blackouts, as CPUC directs PG&E, Edison, and Sempra to procure resource adequacy.

 

Key Points

A CPUC order for utilities to add 3.3 GW of reserves, safeguarding grid reliability during variable renewables and peaks

✅ 3.3 GW procurement to meet resource adequacy targets

✅ Focus on grid reliability during peak evening demand

✅ Prioritizes renewables, storage; limits new fossil builds

 

As if California doesn’t have enough problems with its electric service, now state regulators warn the state may be short on power supplies by 2021 if utilities don’t start lining up new resources now.

In the hopes of heading off a shortfall as America goes electric, the California Public Utilities Commission has ordered the state’s electricity providers to secure 3.3 additional gigawatts of reserve supplies. That’s enough to power roughly 2.5 million homes. Half of it must be in place by 2021 and the rest by August 2023.

The move comes as California is already struggling to accommodate increasingly large amounts of solar power that regularly send electricity prices plunging below zero and force other generators offline so the region’s grid doesn’t overload. The state is also still reeling from a series of deliberate mass blackouts that utilities imposed last month to keep their power lines from sparking wildfires amid strong winds. And its largest power company, PG&E Corp., went bankrupt in January.

Now as natural gas-fired power plants retire under the state’s climate policies, officials are warning the state could run short on electricity on hot evenings, when solar production fades and commuters get home and crank up their air conditioners. “We have fewer resources that can be quickly turned on that can meet those peaks,” utilities commission member Liane Randolph said Thursday before the panel approved the order to beef up reserves.

The 3.3 gigawatts that utilities must line up is in addition to a state rule requiring them to sign contracts for 15% more electricity than they expect to need. Some critics question the need for added supplies, particularly after the state went on a plant-building boom in the 2000s.

But California’s grid managers say the risk of a shortfall is real and could be as high as 4.7 gigawatts, especially during heat waves that test the grid again. Mark Rothleder, with the California Independent System Operator, said the 15% cushion is a holdover from the days before big solar and wind farms made the grid more volatile. Now it may need to be increased, he said.

“We’re not in that world anymore,” said Rothleder, the operator’s vice president of state regulatory affairs. “The complexity of the system and the resources we have now are much different.”

The state’s three major utilities, PG&E, Edison International and Sempra Energy, will be largely responsible for securing new supplies. The commission banned fossil fuels from being used at any new power generators built to meet the requirement — though it left the door open for expansions at existing ones.

Some analysts argue California is exporting its energy policies to Western states, making electricity more costly and less reliable.

PG&E said in an emailed statement that it was pleased the commission didn’t adopt an earlier proposal to require 4 gigawatts of additional resources. Edison similarly said it was “supportive.” Sempra didn’t immediately respond with comment.

 

Extending Deadlines

The pending plant closures are being hastened by a 2020 deadline requiring California’s coastal generators to stop using aging seawater-cooling systems. Some gas-fired power plants have said they’ll simply close instead of installing costly new cooling systems. So the commission on Thursday also asked California water regulators to extend the deadline for five plants.

The Sierra Club, meanwhile, called on regulators to turn away from fossil fuels altogether, saying their decision Thursday “sets California back on its progress toward a clean energy future.”

The move to push back the deadline also faces opposition from neighboring towns. Redondo Beach Mayor Bill Brand, whose city is home to one of the plants in line for an extension, told the commission it wasn’t necessary, since California utilities already have plenty of electricity reserves.

“It’s just piling on to that reserve margin,” Brand said.
