Alberta is tinkering again with its deregulated electricity market, but industry players and observers say the contemplated changes are not expected to deter investment in needed power plants or dramatically affect the price people pay.

The Alberta Electric System Operator has been meeting with interested parties for a year to discuss issues that have been raised about the operating reserves market that provides immediate electricity to the provincial grid in the event a generator suddenly shuts down.

Wayne St. Amour, the system operator's vice-president, said no decision has been made on fine-tuning the market, but legislation governing Alberta's deregulated electrical system may have to be amended for any changes to occur.

He didn't say when that might happen, but discussion reports on the organization's website suggest the independent electric system operator wants to implement at least some of the changes early this year.

"Our ambition is to have a fair, efficient, operational competitive market," St. Amour said. "If there's action to be taken, we'll look at it."

Stakeholders are apparently concerned about "perverse" contract conditions and the organization's influence on prices as well as transparency and "the complexity of the market relative to its size," says a summary document posted on the website.

The system operator is expected to release a discussion paper shortly that includes input from market participants.

Liberal MLA Hugh MacDonald said he is concerned that consumers are being left out of the discussion, just as they were shut out of the decision in 2001 to abandon the regulated system and create Canada's only functioning electricity market.

"What they call consultation is just with the stakeholders who benefit from deregulation," he said. "The consumers are completely left out of the discussion and they are the ones who have to pay the ever-increasing bills."

The system operator says consumers are welcome to comment on discussion papers posted on the Internet at www.aeso.ca.

Joseph Doucet, professor of energy policy at the University of Alberta's School of Business, said he doubted the proposed changes would shake investor confidence in Alberta's energy market, but it is difficult to assess what impact they might have on electricity pricing for consumers.

"It's an important piece, but a small piece of the major wholesale trading market," he said. "It's important for a functioning market but I would be hard-pressed to draw a line to show how the changes impact in terms of dollars and cents on your electric bill."

Evan Bahry, executive director of the Independent Power Producers Society of Alberta, said the proposed changes relate to "a small subset of the energy market — about five per cent of peak demand."

"This is a tweak in the operating reserve market," said Bahry, whose association has 135 members. "I don't think it's of the magnitude that would affect investor confidence."

The Alberta government has been criticized in the past for repeatedly making changes to the legislation that governs the electricity market.

Critics fear too much instability in the system may discourage electricity producers from investing in expensive power plants the province needs to meet a demand that's been surging at an annual rate that's equivalent to the amount of power needed to supply two cities the size of Red Deer.

MacDonald notes the market — not government — now determines when and where to build electrical supply.

He said there's already concern that the downturn in the economy has deferred a number of planned projects and reduced the amount of electricity the province keeps in reserve.

Last month, demand for electricity in Alberta reached an all-time high of 9,806 megawatts, breaking the previous record of 9,710 mW set last January. The Alberta Electric System Operator predicts Alberta will need to boost supply by another 5,000 mW in eight years to meet demand.

Bahry said the proposed reserve market changes reflect a concern that the system operator, the neutral player in the electricity market, is now acting as an agent for the procurement of operating reserves and influencing the price of electricity in the process.

One proposal is to have the electric system operator set the volume of required reserve electricity and have an agency, like the Natural Gas Exchange, purchase it, he said.

"Getting AESO out of market operations and being involved in the pricing dynamic — that seems to be a pretty significant proposal," Bahry said.

Seven small UK energy suppliers must pay renewables fees or risk losing licence

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

 

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

 

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

Duke Energy will spend US$25bn to modernise its US grid

Duke Energy Clean Energy Strategy targets smart grid upgrades, wind and solar expansion, efficient gas, and high-reliability nuclear, cutting CO2, boosting decarbonization, and advancing energy efficiency and reliability for the Carolinas.

 

Key Points

A plan investing in smart grids, renewables, gas, and nuclear to cut CO2 and enhance reliability and efficiency by 2030.

✅ US$25bn smart grid upgrades; US$11bn renewables and gas

✅ 40% CO2 reduction and >80% low-/zero-carbon generation by 2030

✅ 2017 nuclear fleet 95.64% capacity factor; ~90 TWh carbon-free

 

The US power group Duke Energy plans to invest US$25bn on grid modernization over the 2017-2026 period, including the implementation of smart grid technologies to cope with the development of renewable energies, along with US$11bn on the expansion of renewable (wind and solar) and gas-fired power generation capacities.

The company will modernize its fleet and expects more than 80% of its power generation mix to come from zero and lower CO2 emitting sources, aligning with nuclear and net-zero goals, by 2030. Its current strategy focuses on cutting down CO2 emissions by 40% by 2030. Duke Energy will also promote energy efficiency and expects cumulative energy savings - based on the expansion of existing programmes - to grow to 22 TWh by 2030, i.e. the equivalent to the annual usage of 1.8 million households.

Duke Energy’s 11 nuclear generating units posted strong operating performance in 2017, as U.S. nuclear costs hit a ten-year low, providing the Carolinas with nearly 90 billion kilowatt-hours of carbon-free electricity – enough to power more than 7 million homes.

Globally, China's nuclear program remains on a steady development track, underscoring broader industry momentum.

“Much of our 2017 success is due to our focus on safety and work efficiencies identified by our nuclear employees, along with ongoing emphasis on planning and executing refueling outages to increase our fleet’s availability for producing electricity,” said Preston Gillespie, Duke Energy chief nuclear officer.

Some of the nuclear fleet’s 2017 accomplishments include, as a new U.S. reactor comes online nationally:

  • The 11 units achieved a combined capacity factor of 95.64 percent, second only to the fleet’s 2016 record of 95.72 percent, marking the 19th consecutive year of attaining a 90-plus percent capacity factor (a measure of reliability).
  • The two units at Catawba Nuclear Station produced more than 19 billion kilowatt-hours of electricity, and the single unit at Harris Nuclear Plant generated more than 8 billion kilowatt-hours, both setting 12-month records.
  • Brunswick Nuclear Plant unit 2 achieved a record operating run.
  • Both McGuire Nuclear Station units completed their shortest refueling outages ever and unit 1 recorded its longest operating run.
  • Oconee Nuclear Station unit 2 achieved a fleet record operating run.

The Robinson Nuclear Plant team completed the station’s 30th refueling outage, which included a main generator stator replacement and other life-extension activities, well ahead of schedule.

“Our nuclear employees are committed to providing reliable, clean electricity every day for our Carolinas customers,” added Gillespie. “We are very proud of our team’s 2017 accomplishments and continue to look for additional opportunities to further enhance operations.”

Thermal power plants’ PLF up on rising demand, lower hydro generation

India Coal Power PLF rose as capacity utilisation improved on rising peak demand and hydropower shortfall; thermal plants lifted plant load factor, IPPs lagged, and generation beat program targets amid weak rainfall and slower snowmelt.

 

Key Points

Coal plant load factor in India rose in May on higher demand and weak hydropower, with generation beating targets.

✅ PLF rose to 65.3% as demand climbed

✅ Hydel generation fell 14% YoY on poor rainfall

✅ IPP PLF at 57.8%, below 60% debt comfort

 

Capacity utilisation levels of coal-based power plants improved in May because of a surge in electricity demand and lower generation from hydroelectric sources. The plant load factor (PLF) of thermal power plants went up to 65.3% in the month, 1.7 percentage points higher than the year-ago period.

While PLFs of central and state government-owned plants were 75.5% and 64.5%, respectively, the same for independent power producers (IPPs) stood at 57.8%, even as coal and electricity shortages eased across the market. Though PLFs of IPPs were higher than May 2017 levels, it failed to cross the 60% mark, which eases debt servicing capabilities of power generation assets.

Thermal power plants generated 96,580 million units (MU) in May, 4% more than the programme set for the month and 5.2% higher than last year, partly supported by higher imported coal volumes in the market. On the other hand, hydel plants produced 10,638 MU, 10% lower than the target, reflecting a 14% decline from last year.

#google#

Peak demand of power on the last day of the month was 1,62,132 MW, 4.3% higher than the demand registered in the same day a year ago, underscoring India's position as the third-largest electricity producer globally.

According to sources, hydropower plants have been generating lesser than expected electricity due to inadequate rainfall and snow melting at a slower pace than previous years, even as the US reported a power generation jump year on year. Data for power generation from renewable sources have not been made available yet.

Sierra Club: Governor Abbott's Demands Would Leave Texas More Polluted and Texans in the Dark

Texas Energy Policy Debate centers on ERCOT and PUC directives, fossil fuels vs renewables, grid reliability, energy efficiency, battery storage, and blackout risks, shaping Texas power market rules, conservation alerts, and capacity planning.

 

Key Points

Policy fight over ERCOT/PUC rules weighing fossil fuels vs renewables and storage to bolster Texas grid reliability.

✅ ERCOT and PUC directives under political scrutiny

✅ Fossil fuel subsidies vs renewable incentives and storage

✅ Focus on grid reliability, efficiency, and blackout prevention

 

Earlier this week, Governor Abbott released a letter to the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT), demanding electricity market reforms that Abbott falsely claims will "increase power generation capacity and to ensure the reliability of the Texas power grid."

Unfortunately, Abbott's letter promotes polluting, unreliable fossil fuels, attacks safer clean energy options, and ignores solutions that would actually benefit everyday Texans.

"Governor Abbott, in a blatant effort to politicize Texans' energy security, wants to double down on fossil fuels, even though they were the single largest point of failure during both February's blackouts and June's energy conservation alerts," said Cyrus Reed, Interim Director & Conservation Director of the Lone Star Chapter of the Sierra Club.

"Many of these so-called solutions were considered and rejected most recently by the Texas Legislature. Texas must focus on expanding clean and reliable renewable energy, energy efficiency, and storage capacity, as voters consider funding to modernize generation in the months ahead.

"We can little afford to repeat the same mistakes that have failed to provide enough electricity where it is needed most and cost Texans billions of dollars. Instead of advocating for evidence-based solutions, Abbott wants to be a culture warrior for coal and gas, even as he touts grid readiness amid election season, even when it results in blackouts across Texas."

Spain plans switch to 100% renewable electricity by 2050

Spain 2050 Renewable Energy Plan drives decarbonisation with wind and solar, energy efficiency, fossil fuel bans, and Paris Agreement targets, enabling net-zero power, emissions cuts, and just transition measures for workers and coal regions.

 

Key Points

A roadmap to 100 percent renewable power by 2050, deep emissions cuts, and a just transition aligned with Paris goals.

✅ Adds 3,000 MW of wind and solar each year through 2030

✅ Bans new fossil fuel drilling, hydrocarbon extraction, and fracking

✅ Targets 35% energy efficiency gains and 35% green power by 2030

 

Spain has launched an ambitious plan to switch its electricity system entirely to renewable sources, similar to California's 100% clean electricity mandate, by 2050 and completely decarbonise its economy soon after.

By mid-century, as EU electricity demand projections suggest increases, greenhouse gas emissions would be slashed by 90% from 1990 levels under Spain’s draft climate change and energy transition law.

To do this, the country’s social democratic government is committing to installing at least 3,000MW of wind and solar power capacity every year in the next 10 years ahead.

New licences for fossil fuel drills, hydrocarbon exploitation and fracking wells, will be banned, and a fifth of the state budget will be reserved for measures that can mitigate climate change. This money will ratchet upwards from 2025.

Christiana Figueres, a former executive secretary of the UN’s framework convention on climate change (UNFCCC), hailed the draft Spanish law as “an excellent example of the Paris agreement”. She added: “It sets a long-term goal, provides incentives on scaling up emissions technologies and cares about a good transition for the workforce.”

Under the plan, “just transition” contracts will be drawn up, similar to the £220m package announced in October, that will shut most Spanish coalmines in return for a suite of early retirement schemes, re-skilling in clean energy jobs, and environmental restoration. These deals will be partly financed by auction returns from the sale of emissions rights.

The government has already scrapped a controversial “sun tax” that halted Spain’s booming renewables sector earlier this decade, even as IEA analysis finds solar the cheapest electricity worldwide, and the new law will also mandate a 35% electricity share for green energy by 2030.

James Watson, chief executive of the SolarPower Europe trade association, said the law was “a wake-up call to the rest of the world” amid debate on the global energy transition today.

Energy efficiency will also be improved by 35% within 11 years, and government and public sector authorities will be able to lease only buildings that have almost zero energy consumption.

Laurence Tubiana, chief executive of the European Climate Foundation, and former French climate envoy who helped draft the Paris accord, described the agreement as groundbreaking and inspirational. “By planning on going carbon neutral, Spain shows that the battle against climate change is deadly serious, that they are ready to step up and plan to reap the rewards of decarbonisation,” she said.

However, the government’s hold on power is fragile. With just a quarter of parliamentary seats it will depend on the more leftwing Podemos and liberal Ciudadanos parties to pass the climate plan.

No dates were included in the legislation for phaseouts of coal or nuclear energy, and, echoing UK net zero policy shifts, a ban on new cars with petrol or diesel engines was delayed until 2040.

PG&E says power lines may have started 2 California fires

PG&E Wildfire Blackouts highlight California power shutoffs as high winds and suspected transmission line faults trigger evacuations, CPUC investigations, and grid safety reviews, with utilities weighing risk, compliance, and resilience during Santa Ana conditions.

 

Key Points

PG&E Wildfire Blackouts are outages during wind-driven fire threats linked to power lines, spurring CPUC investigations.

✅ Wind and line faults suspected amid Lafayette evacuations

✅ CPUC to probe shutoffs, notifications, and compliance

✅ Utilities plan more outages as Santa Ana winds return

 

Pacific Gas & Electric Co. power lines may have started two wildfires over the weekend in the San Francisco Bay Area, the utility said Monday, even though widespread blackouts were in place to prevent downed lines from starting fires during dangerously windy weather.

The fires described in PG&E reports to state regulators match blazes that destroyed a tennis club and forced evacuations in Lafayette, about 20 miles (32 kilometres) east of San Francisco.

The fires began in a section of town where PG&E had opted to keep the lights on. The sites were not designated as a high fire risk, the company said.

Powerful winds were driving multiple fires across California and forcing power shut-offs intended to prevent blazes, even as electricity prices are soaring across the state as well.

More than 900,000 power customers -- an estimated 2.5 million people -- were in the dark at the height of the latest planned blackout, nearly all of them in PG&E's territory in Northern and central California. By Monday evening a little less than half of those had their service back. But some 1.5 million people in 29 counties will be hit with more shut-offs starting Tuesday because another round of strong winds is expected, a reminder of grid stress during heat waves that test capacity, the utility said.

Southern California Edison had cut off power to 25,000 customers and warned that it was considering disconnecting about 350,000 more as power supply lapses and Santa Ana winds return midweek.

PG&E is under severe financial pressure after its equipment was blamed for a series of destructive wildfires and its 2018 Camp Fire guilty plea compounded liabilities during the past three years. Its stock dropped 24% Monday to close at $3.80 and was down more than 50% since Thursday.

The company reported last week that a transmission tower may have caused a Sonoma County fire that has forced 156,000 people to evacuate.

PG&E told the California Public Utilities Commission that a worker responded to a fire in Lafayette late Sunday afternoon and was told firefighters believed contact between a power line and a communication line may have caused it.

A worker went to another fire about an hour later and saw a fallen pole and transformer. Contra Costa Fire Department personnel on site told the worker they were looking at the transformer as a potential ignition source, a company official wrote.

Separately, the company told regulators that it had failed to notify 23,000 customers, including 500 with medical conditions, before shutting off their power earlier this month during windy weather.

Before a planned blackout, power companies are required to notify customers and take extra care to get in touch with those with medical problems who may not be able to handle extended periods without air conditioning or may need power to run medical devices.

PG&E said some customers had no contact information on file. Others were incorrectly thought to be getting electricity.

After that outage, workers discovered 43 cases of wind-related damage to power lines, transformers and other equipment.

Jennifer Robison, a PG&E spokeswoman, said the company is working with independent living centres to determine how best to serve people with disabilities.

The company faced a growing backlash from regulators and lawmakers, and a judge's order on wildfire risk spending added pressure as well.

U.S. Rep. Josh Harder, a Democrat from Modesto, said he plans to introduce legislation that would raise PG&E's taxes if it pays bonuses to executives while engaging in blackouts.

The Public Utilities Commission plans to open a formal investigation into the blackouts and the broader climate policy debate surrounding reliability within the next month, allowing regulators to gather evidence and question utility officials. If rules are found to be broken, they can impose fines up to $100,000 per violation per day, said Terrie Prosper, a spokeswoman for the commission.

The commission said Monday it also plans to review the rules governing blackouts, will look to prevent utilities from charging customers when the power is off and will convene experts to find grid improvements that might lessen blackouts during next year's fire season, as debates over rate stability in 2025 continue across PG&E's service area.

The state can't continue experiencing such widespread blackouts, "nor should Californians be subject to the poor execution that PG&E in particular has exhibited," Marybel Batjer, president of the California Public Utilities Commission, said in a statement.
