Two companies will build a two-megawatt solar energy system at Denver International Airport.

WorldWater & Solar Technologies Corp. will design and build the system, which will be located at DIA's main terminal. MMA Renewable Ventures will own and operate the system and sell power to DIA under a long-term contract.

The system, which will be up and running next year, is expected to generate 3.5 million kilowatt-hours of electricity annually. The companies said that will reduce carbon emissions by more than 5 million pounds a year.

"DIA will benefit from a renewable energy system that is cost-effective from the day it becomes operational and for years to come," Matt Cheney, chief executive officer of MMA Renewable Ventures, said in a press release.

Ontario introduces new 'ultra-low' overnight hydro pricing

Ontario Ultra-Low Overnight Electricity Rates cut costs for shift workers and EV charging, with time-of-use pricing, off-peak savings, on-peak premiums, kilowatt-hour details, and Ontario Energy Board guidance for homes and businesses across participating utilities.

 

Key Points

Ontario's ultra-low overnight plan: 2.4c/kWh 11pm-7am for EVs, shift workers; higher daytime on-peak pricing.

✅ 2.4c/kWh 11pm-7am; 24c/kWh on-peak 4pm-9pm

✅ Best for EV charging, shift work, night usage

✅ Available provincewide by Nov 1 via local utilities

 

The Ontario government is introducing a new ultra-low overnight price plan that can benefit shift workers and individuals who charge electric vehicles while they sleep.

Speaking at a news conference on Tuesday, Energy Minister Todd Smith said the new plan could save customers up to $90 a year.

“Consumer preferences are still changing and our government realized there was more we could do, especially as the province continues to have an excess supply of clean electricity at night when province-wide electricity demand is lower,” Smith said, noting a trend underscored by Ottawa's demand decline during the pandemic.

The new rate, which will be available as an opt-in option as of May 1, will be 2.4 cents per kilowatt-hour from 11 p.m. to 7 a.m. Officials say this is 67 per cent lower than the current off-peak rate, which saw a off-peak relief extension during the pandemic.

However, customers should be aware that this plan will mean a higher on-peak rate, as unlike earlier calls to cut peak rates, Hydro One peak charges remained unchanged for self-isolating customers.

The new plan will be offered by Toronto Hydro, London Hydro, Centre Wellington Hydro, Hearst Power, Renfrew Hydro, Wasaga Distribution, and Sioux Lookout Hydro by May. Officials have said this will be expanded to all local distribution companies by Nov. 1.

With the new addition of the “ultra low” pricing, there are now three different electricity plans that Ontarians can choose from. Here is what you have to know about the new hydro options:

TIME OF USE:
Most residential customers, businesses and farms are eligible for these rates, similar to BC Hydro time-of-use proposals in another province, which are divided into off-peak, mid-peak and on-peak hours.

This is what customers will pay as of May 1 according to the Ontario Energy Board, following earlier COVID-19 electricity relief measures that temporarily adjusted rates:

 Off-peak (Weekdays between 7 p.m. and 7 a.m. and on weekends/holidays): 7.4 cents per kilowatt-hour
 Mid-Peak (Weekdays between 7 a.m. and 11 a.m., and between 5 p.m. and 7 p.m.): 10.2 cents per kilowatt-hour
 On-Peak ( Weekdays 11 a.m. to 5 p.m.): 15.1 cents per kilowatt-hour

TIERED RATES
This plan allows customers to get a standard rate depending on how much electricity is used. There are various thresholds per tier, and once a household exceeds that threshold, a higher price applies. Officials say this option may be beneficial for retirees who are home often during the day or those who use less electricity overall.

The tiers change depending on the season. This is what customers will pay as of May 1:

 Residential households that use 600 kilowatts of electricity per month and non-residential businesses that use 750 kilowatts per month: 8.7 cents per kilowatt-hour.
 Residences and businesses that use more than that will pay a flat rate of 10.3 cents per kilowatt-hour


ULTRA-LOW OVERNIGHT RATES
Customers can opt-in to this plan if they use most of their electricity overnight.

This is what customers will pay as of May 1:

  •  Between 11 p.m. and 7 a.m.: 2.4 cents per kilowatt-hour
  •  Weekends and holidays between 7 a.m. and 11 p.m.: 7.4 cents per kilowatt-hour
  •  Mid-Peak (Weekdays between 7 a.m. and 4 p.m., and between 9 p.m. and 11 p.m.): 10.2 cents per kilowatt-hour
  •  On-Peak (weekdays between 4 p.m. and 9 p.m.): 24 cents per kilowatt-hour

More information on these plans can be found on the Ontario Energy Board website, alongside stable pricing for industrial and commercial updates from the province.

Utilities commission changes community choice exit fees; what happens now in San Diego?

CPUC Exit Fee Increase for CCAs adjusts the PCIA, affecting utilities, San Diego ratepayers, renewable energy procurement, customer equity, and cost allocation, while providing regulatory certainty for Community Choice Aggregation programs and clean energy goals.

 

Key Points

A CPUC-approved change raising PCIA exit fees paid by CCAs to utilities, balancing cost shifts and customer equity.

✅ PCIA rises from about 2.5c to roughly 4.25c per kWh in San Diego

✅ Aims to reduce cost shifts and protect non-CCA customers

✅ Offers regulatory certainty for CCA launches and clean energy goals

 

The California Public Utilities Commission approved an increase on the exit fees charged to customers who take part in Community Choice Aggregation -- government-run alternatives to traditional utilities like San Diego Gas & Electric.

After reviewing two competing exit fee proposals, all five commissioners voted Thursday in favor of an adjustment that many CCA advocates predicted could hamper the growth of the community choice movement.

But minutes after the vote was announced, one of the leading voices in favor of the city San Diego establishing its own CCA said the decision was good news because it provides some regulatory certainty.

"For us in San Diego, it's a green light to move forward with community choice," said Nicole Capretz, executive director of the Climate Action Campaign. "For us, it's let's go, let's launch and let's give families a choice. We no longer have to wait."

Under the CCA model, utilities still maintain transmission and distribution lines (poles and wires, etc.) and handle customer billing. But officials in a given local government entity make the final decisions about what kind of power sources are purchased.

Once a CCA is formed, its customers must pay an exit fee -- called a Power Charge Indifference Adjustment -- to the legacy utility serving that particular region. The fee is included in customers' monthly bills.

The fee is required to offset the costs of the investments utilities made over the years for things like natural gas power plants, renewable energy facilities and other infrastructure.

Utilities argue if the exit fee is set too low, it does not fairly compensate them for their investments; if it's too high, CCAs complain it reduces the financial incentive for their potential customers.

The Public Utilities Commission chose to adopt a proposal that some said was more favorable to utilities, leading to complaints from CCA boosters.

"We see this will really throw sand in the gears in our ability to do things that can move us toward (climate change) goals," Jim Parks, staff member of Valley Clean Energy, a CCA based in Davis, said before the vote.

Commissioner Carla Peterman, who authored the proposal that passed, said she supports CCAs but stressed the commission has a "legal obligation" to make sure increased costs are not shouldered by "customers who do not, or cannot, join a CCA. Today's proposal ensures a more level playing field between customers."

As for what the vote means for the exit fee in San Diego, Peterman's office earlier in the week estimated the charge would rise from 2.5 cents a kilowatt-hour to about 4.25 cents.

The Clear the Air Coaltion, a San Diego County group critical of CCAs, said the newly established exit fee -- which goes into effect starting next year -- is "a step in the direction."

But the group, which includes the San Diego Regional Chamber of Commerce, the San Diego County Taxpayers Association and lobbyists for Sempra Energy (the parent company of SDG&E), repeated concerns it has brought up before.

"If the city of San Diego decides to get into the energy business this decision means ratepayers in National City, Chula Vista, Carlsbad, Imperial Beach, La Mesa, El Cajon and all other neighboring communities would see higher energy bills, and San Diego taxpayers would be faced with mounting debt," coalition spokesman Tony Manolatos said in an email.

CCA supporters say community choice is critical in ensuring San Diego meets the pledge made by Mayor Kevin Faulconer to adopt the city's Climate Action Plan, mandating 100 percent of the city's electricity needs must come from renewable sources by 2035.

Now attention turns to Faulconer, who promised to make a decision on bringing a CCA proposal to the San Diego City Council only after the utilities commission made its decision.

A Faulconer spokesman said Thursday afternoon that the vote "provides the clarity we've been waiting for to move forward" but did not offer a specific time table.

"We're on schedule to reach Mayor Faulconer's goal of choosing a pathway that achieves our renewable energy goals while also protecting ratepayers, and the mayor looks forward to making his recommendation in the next few weeks," said Craig Gustafson, a Faulconer spokesman, in an email.

A feasibility study released last year predicted a CCA in San Diego has the potential to deliver cheaper rates over time than SDG&E's current service, while providing as much as 50 percent renewable energy by 2023 and 80 percent by 2027.

"The city has already figured out we are still capable of launching a program, having competitive, affordable rates and finally offering families a choice as to who their energy provider is," said Capretz, who helped draft an initial blueprint of the climate plan as a city staffer.

SDG&E has come to the city with a counterproposal that offers 100 percent renewables by 2035.

Thus far, the utility has produced a rough outline for a "tariff" program that would charge ratepayers the cost of delivering more clean sources of energy over time.

Some council members have expressed frustration more specifics have not been sketched out.

SDG&E officials said they will take the new exit fee into account as they go forward with their counterproposal to the city council.

Speaking in general about the utility commission's decision, SDG&E spokeswoman Helen Gao called it "a victory for our customers, as it minimizes the cost shifts that they have been burdened with under the existing fee formula.

"As commissioners noted in rendering their decision, reforming the (exit fee) addresses a customer-to-customer equity issue and has nothing to do with increasing profits for investor-owned utilities," Gao said in an email.

China boosts wind energy, photovoltaic and concentrated solar power

China Renewable Energy Law drives growth in wind power, solar thermal, and photovoltaic capacity, supporting grid integration and five-year plans, even as China leads CO2 emissions, with policy incentives, compliance inspections, and national resource assessments.

 

Key Points

A legal framework that speeds wind, solar thermal, and PV growth in China via mandates, incentives, and grid rules.

✅ 2018 renewables: 1.87T kWh, 26.7% of national power

✅ Over 100 State Council policies enabling deployment

✅ Law inspections and regional oversight across six provinces

 

China leads renewable energies, installing more wind power, solar thermal and photovoltaic than any other country, as seen in the China solar PV growth reported in 2016, but also leads CO2 emissions, and much remains to be done.

The effective application of Chinas renewable energy law has boosted the use of renewable energy in the country and facilitated the rapid development of the sector, as solar parity across Chinese cities indicates, a report said.

The report on compliance with renewable energy law was presented today at the current bimonthly session of the Standing Committee of the National Peoples Assembly (APN).

Electricity generated by renewable energy amounted to about 1.87 trillion kilowatts per hour in 2018, representing 26.7 percent of Chinas total energy production in the year, aligning with trends where wind and solar doubling globally over five years, the report said.

Ding Zhongli, vice president of the NPC Standing Committee, presented the report to the legislators at the second plenary meeting of the session.

An inspection of the law enforcement was carried out from August to November, as U.S. renewables hit 28% record showed momentum elsewhere. A total of 21 members of the NPC Standing Committee and the NPC Environmental Protection and Resource Conservation Committee, as well as national legislators, traveled to six regions at the provincial level on inspection visits. Twelve legislative bodies at the provincial level inspected the law enforcement efforts in their jurisdictions.

The relevant State Council agencies have implemented more than 100 regulations and policies to foster a good policy environment for the development of renewable energy, as seen in markets where U.S. renewable electricity surpassed coal in 2022. Local regulations have also been formulated based on local conditions, according to the report.

In accordance with the law, a thorough investigation of the national conditions of renewable energy resources was undertaken.

In 2008 and 2014 atlas of solar energy resources and wind energy evaluation of China were issued. The relevant agencies of the State Council have also implemented five-year plans for the development of renewable energy, which have provided guidance to the sector, while countries like Ireland's one-third green power target remain in focus within four years.

The main provisions of the law have been met, the law has been effectively applied and the purpose of the legislation has been met, and this momentum is echoed abroad, with U.S. renewables near one-fourth according to projections, Ding said.

Germany extends nuclear power amid energy crisis

Germany Nuclear Power Extension keeps Isar 2, Neckarwestheim 2, and Emsland running as Olaf Scholz tackles the energy crisis, soaring gas prices, and EU winter demand, prioritizing grid stability amid the Ukraine war.

 

Key Points

A temporary policy keeping three German reactors online to enhance grid stability and national energy security.

✅ Extends Isar 2, Neckarwestheim 2, and Emsland operations

✅ Addresses EU energy crisis and soaring gas prices

✅ Prioritizes grid stability while coal phase-out advances

 

German Chancellor Olaf Scholz has ordered the country's three remaining nuclear power stations to keep operating until mid-April, signalling a nuclear U-turn as the energy crisis sparked by Russia's invasion of Ukraine hurts the economy.

Originally Germany planned to phase out all three by the end of this year, continuing its nuclear phaseout policy at the time.

Mr Scholz's order overruled the Greens in his coalition, who wanted two plants kept on standby, to be used if needed.

Nuclear power provides 6% of Germany's electricity.

The decision to phase it out was taken by former chancellor Angela Merkel after Japan's Fukushima nuclear disaster in 2011.

But gas prices have soared since Russia's invasion of Ukraine in February, which disrupted Russia's huge oil and gas exports to the EU, though some officials argue that nuclear would do little to solve the gas issue in the short term. In August Russia turned off the gas flowing to Germany via the Nord Stream 1 undersea pipeline.

After relying so heavily on Russian gas Germany is now scrambling to maintain sufficient reserves for the winter. The crisis has also prompted it to restart mothballed coal-fired power stations, with coal generating about a third of its electricity currently, though the plan is to phase out coal in the drive for green energy.

Last year Germany got 55% of its gas from Russia, but in the summer that dropped to 35% and it is declining further.

EU leaders consider how to cap gas prices
France sends Germany gas for first time amid crisis
Chancellor Scholz's third coalition partner, the liberal Free Democrats (FDP), welcomed his move to keep nuclear power as part of the mix. The three remaining nuclear plants are Isar 2, Neckarwestheim 2 and Emsland, which were ultimately shut down after the extension.

The Social Democrat (SPD) chancellor also called for ministries to present an "ambitious" law to boost energy efficiency and to put into law a phase-out of coal by 2030, aiming for a coal- and nuclear-free economy among major industrial nations.

Last week climate activist Greta Thunberg said it was a "mistake" for Germany to press on with nuclear decommissioning while resorting to coal again, intensifying debate over a nuclear option for climate goals nationwide.

94,000 lose electricity in LA area after fire at station

Los Angeles Power Station Fire prompts LADWP to shut a Northridge/Reseda substation, causing a San Fernando Valley outage amid a heatwave; high-voltage equipment and mineral oil burned as 94,000 customers lost power, elevator rescues reported.

 

Key Points

An LADWP substation fire in Northridge/Reseda caused a major outage; 94,000 customers affected as crews restore power.

✅ Fire started around 6:52 p.m.; fully extinguished by 9 p.m.

✅ High-voltage gear and mineral oil burned; no injuries reported.

✅ Outages hit Porter Ranch, Reseda, West Hills, Granada Hills.

 

About 94,000 customers were without electricity Saturday night after the Los Angeles Department of Water and Power shut down a power station in the northeast San Fernando Valley that caught fire, the agency said.

The fire at the station in the Northridge/Reseda area of Los Angeles started about 6:52 p.m. and involved equipment that carries high-voltage electricity and distributes it at lower voltages to customers in the surrounding area, the department said, even as other utilities sometimes deploy wildfire safety shut-offs to reduce risk during dangerous conditions.

The department shut off power to the station as a precautionary move, and it is restoring power now that the fire has been put out, similar to restoration after intentional shut-offs in other parts of California. Initially, 140,000 customers were without power. That number had been cut to 94,000 by 11 p.m.

The power outage comes as much of California baked in heat that broke records, and rolling blackout warnings were issued as the grid strained. A record that stood 131 years in Los Angeles was snapped when the temperature spiked at 98 degrees downtown.

People reported losing power in Porter Ranch, Winnetka, West Hills, Canoga Park, Woodland Hills, Granada Hills, North Hills, Reseda and Chatsworth, KABC TV reported, highlighting electricity inequality across communities.

Shortly after the blaze broke out, firefighters found a huge container of mineral oil that is used to cool electrical equipment on fire, Los Angeles Fire Department spokesman Brian Humphrey told the Los Angeles Times. The incident underscores infrastructure risks that in some regions have required a complete grid rebuild after severe storms.

Firefighters had the blaze under control by 8:30 p.m. and were able to put it out by 9 p.m., Humphrey said. "These were fierce flames, with smoke towering more than 300 feet into the sky," he told the newspaper.

No one was injured.

Firefighters rescued people who were stranded in elevators, Humphrey said.

BC Hydro Expects To See Electricity Usage Rise This Holiday Season

BC Hydro Holiday Electricity Usage is set to rise as energy demand increases during peak 4-10 pm on Christmas and Boxing Day, driven by larger gatherings, more cooking, and eased COVID-19 restrictions province-wide.

 

Key Points

Expected rise in power demand on Christmas and Boxing Day evenings versus 2020, driven by larger gatherings and cooking.

✅ Peak hours 4-10 pm expected to rise in provincial load.

✅ 2020 saw 4% and 7% drops vs 2019 on Christmas and Boxing Day.

✅ Holiday lighting adds ~3% to use; switching to LED can save ~$40.

 

BC Hydro data showed residential electricity load in the Cariboo and throughout the province, even as drought affects generation dynamics heading into winter, dropped on Christmas Day and Boxing Day in 2020.

Northern Community Relations Manager, Bob Gammer, said the decrease was due in part to more people following the COVID-19 restrictions and not getting together for big meals, even though 2018 Earth Hour usage increased elsewhere illustrates how behavior can sometimes raise demand.

However, this year Gammer said between 4 and 10 pm on those two days, BC Hydro does expect to see a change in overall usage, aligning with all-time high demand trends reported recently in B.C.

“On Christmas Day and Boxing Day, we expect to see increases through those hours and a little bit more so between 4 and 10 pm we should see the amount of power being consumed across the province, as record-breaking 2021 demand indicated earlier, going up compared to what it was on those two days last year.”

In 2020 on Christmas Day evening hydro usage dropped by over 4 percent and Boxing Day evening decreased by 7 percent compared to 2019, whereas regions like Calgary's winter demand have seen spikes during extreme cold.

Gammer added after BC Hydro surveyed their customers and introduced a winter payment plan, they expect to see a lot more cooking happening on Christmas Day and Boxing Day this year as people are intending to have larger gatherings and visit friends.

We asked Gammer about hydro usage when it comes to homes decked out for the holidays, and how that compares to newer loads like crypto mining activity in B.C.

“The Christmas lighting displays people have, not just indoors but outdoors as well, what we’re seeing is about a 3 percent increase in electricity consumption overall through the Christmas season. If people switch, if you still have older lights that are incandescent, switch those over to LED, and through the season it could wind up saving you $40 in electricity just switching over about 8 strings of lights to LED.”
