Hurricane Katrina helped University of Texas professor, Alexis Kwasinski, formulate a new plan for the U.S. telecom system: a de-centralized power architecture that would have kept the lights and phones on in New Orleans.

Kwasinski maintains that a microgrid-based power plant with its own local power sources and independent control would be more dependable, efficient, and cost effective than traditional telecom power systems.

Microgrids would also be a quick and inexpensive way to include renewable energy sources for both existing and developing systems.

"There has been surprisingly little research on disaster damage and restoration of telecommunications systems," says Kwasinski. "My survey of the Gulf coast after Katrina showed how devastating a single downed line or incapacitated substation can be. The answer is diverse power input. You integrate different types of local power sources with diverse energy delivery infrastructures through multiple-input converter modules."

Since the communications industry power standard is direct current (DC) local networks, Kwasinski is exploring DC generation systems using a microgrid-based telecom power plant with a modular distributed architecture. Energy would come from a mixture of renewable energy sources, microturbines, fuel cells, and interconnection to the existing utility grid. Converters in secondary distribution frames would isolate short circuit currents. Since the utility grid is a secondary source, the microgrid would be protected against the grid's surges and failures.

The savings would be generous. Microgrids could "sell" excess power to the utility grid.

Costs decrease because of reduced energy storage, less down time, equipment operating at maximum efficiency, lower hardware expense, and optimal power input control based on energy costs.

"I think the most exciting aspect of the research is how flexible this approach is," says Kwasinski. "It works for developing countries who can add components to the system as they can afford it. Existing systems can easily be retrofitted with a microgrid system operating as a secondary distribution method. Small devices like solar panels and windmills can be added ad hoc, making for a painless transition to renewable energy at a competitive cost."

Berlin urged to remove barriers to PV

Germany Solar Cap Removal would accelerate photovoltaics, storage, and renewables, replacing coal and nuclear during phaseout with 10GW per year toward 162GW by 2030, boosting grid resilience, O&M jobs, and domestic clean energy growth.

 

Key Points

A policy change to scrap the 52GW limit, enabling 10GW/year PV and storage to replace coal and nuclear capacity.

✅ Scrap 52GW cap to prevent post-2020 market slump

✅ Add 10GW PV annually; scale residential, commercial, grid storage

✅ Create jobs in planning, installation, and O&M through 2030

 

The German Solar Association (BSW) has called on the government to remove barriers to the development of new solar power capacity in Germany and storage capacity needed to replace coal and nuclear generation that is being phased out.

A 52GW cap should be scrapped, otherwise there is a risk that a market slump will occur in the solar industry after 2020, BSW said, especially as U.S. solar expansion plans signal accelerating global demand.

BSW managing director Carsten Körnig said: “Time is running out, and further delays are irresponsible. The 52GW mark will already be reached within a few months.”
A new report from BSW, in cooperation with Bonn-based marketing and social research company EuPD Research and The smarter E Europe initiative, said 10GW a year is needed as well as an increase in battery storage capacity.

This would lead to cumulative photovoltaic capacity of 162GW and 15GW residential, commercial and grid storage systems by 2030, in line with global renewable records being set, leading to new job opportunities.

The number of jobs in the domestic photovoltaic and storage industries could increase to 78,000 by the end of the next decade from today’s level of 26,400, aligning with forecasts of wind and solar reaching 50% by mid-century, said 'The Energy Transition in the Context of the Nuclear and Coal Phaseout – Perspectives in the Electricity Market to 2040' study.

Job growth would take place for the most part in the fields of planning, installation and operations and maintenance of PV systems, as solar uptake in Poland increases, the report said.

In maintenance alone, employment would increase from 9,200 to 26,000, with additional opened up by tapping into the market potential of medium- to long-term storage systems, alongside changing electricity prices in Northern Europe that favor flexibility, it said.

The report added that industry revenue could grow from €5bn to €12.5bn in the coming decade.

The report was supported by BayWa Re E3/DC, Fronius, Goldbeck Solar, IBC Solar, Panasonic, Sharp, Siemens, Sonnen, Suntech, Tesvolt and Varta.

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.

Financial update from N.L energy corp. reflects pandemic's impact

Nalcor Energy Pandemic Loss underscores Muskrat Falls delays, hydroelectric risks, oil price shocks, and COVID-19 impacts, affecting ratepayers, provincial debt, timelines, and software commissioning for the Churchill River project and Atlantic Canada subsea transmission.

 

Key Points

A $171M Q1 2020 downturn linked to COVID-19, oil price collapse, and Muskrat Falls delays impacting schedules and costs.

✅ Q1 2020 profit swing: +$92M to -$171M amid oil price crash

✅ Muskrat Falls timeline slips; cost may reach $13.1B

✅ Software, workforce, COVID-19 constraints slow commissioning

 

Newfoundland and Labrador's Crown energy corporation reported a pandemic-related profit loss from the first quarter of 2020 on Tuesday, along with further complications to the beleaguered Muskrat Falls hydroelectric project.

Nalcor Energy recorded a profit loss of $171 million in the first quarter of 2020, down from a $92 million profit in the same period last year, due in part to falling oil prices during the COVID-19 pandemic.

The company released its financial statements for 2019 and the first quarter of 2020 on Tuesday, and officials discussed the numbers in a livestreamed presentation that detailed the impact of the global health crisis on the company's operations.

The loss in the first quarter was caused by lower profits from electricity sales and a drop in oil prices due to the pandemic and other global events, company officials said.

The novel coronavirus also added to the troubles plaguing the Muskrat Falls hydroelectric dam on Labrador's Churchill River, amid Quebec-N.L. energy tensions that long predate the pandemic.

Work at the remote site stopped in March over concerns about spreading the virus. Operations have been resuming slowly, with a reduced workforce tackling the remaining jobs.

Officials with Nalcor said it will likely be another year before the megaproject is complete.

CEO Stan Marshall estimates the months of delays could bring the total cost to $13.1 billion including financing, up from the previous estimate of $12.7 billion -- though the total impact of the coronavirus on the project's price tag has yet to be determined.

"If we're going to shut down again, all of that's wrong," Marshall said. "But otherwise, we can just carry on and we'll have a good idea of the productivity level. I'm hoping that by September we'll have a more definitive number here."

The 824 megawatt hydroelectric dam will eventually send power to Newfoundland, and later Nova Scotia, through subsea cables, even as Nova Scotia boosts wind and solar in its energy mix.

It has seen costs essentially double since it was approved in 2012, and faced significant delays even before pandemic-forced shutdowns in North America and around the world this spring.

Cost and schedule overruns were the subject of a sweeping inquiry that held hearings last year, while broader generation choices like biomass use have drawn scrutiny as well.

The commissioner's report faulted previous governments for failing to protect residents by proceeding with the project no matter what, and for placing trust in Nalcor executives who "frequently" concealed information about schedule, cost and related risks.

Some of the latest delays have come from challenges with the development of software required to run the transmission link between Labrador and Newfoundland, where winter reliability issues have been flagged in reports.

The software is still being worked out, Marshall said Tuesday, and the four units at the dam will come online gradually over the next year.

"It's not an all or nothing thing," Marshall said of the final work stages.
Nalcor's financial snapshot follows a bleak fiscal update from the province this month. The Liberal government reported a net debt of $14.2 billion and a deficit of more than $1.1 billion, even as a recent Churchill Falls deal promised new revenues for the province, citing challenges from pandemic-related closures and oil production shutdowns.

Finance Minister Tom Osborne said at the time that help from Ottawa will be necessary to get the province's finances back on track.

Muskrat Falls represents about one-third of the province's debt, and is set to produce more power than the province of about half a million people requires. Anticipated rate increases due to the ballooning costs and questions about Muskrat Falls benefits have posed a significant political challenge for the provincial government.

Ottawa has agreed to work with Newfoundland and Labrador on a rewrite of the project's financial structure, scrapping the format agreed upon in past federal-provincial loan agreements in order to ease the burden on ratepayers, while some argue independent planning would better safeguard ratepayers.

Marshall, a former Fortis CEO who was brought in to lead Nalcor in 2016, has called the project a "boondoggle" and committed to seeing it completed within four years. Though that plan has been disrupted by the pandemic, Marshall said the end is in sight.

"I'm looking forward to a year from now. And I hope to be gone," Marshall said.

Enel Starts Operations of 450 MW Wind Farm in U.S

High Lonesome Wind Farm powers Texas with 500 MW of renewable energy, backed by a 12-year PPA with Danone North America and a Proxy Revenue Swap, cutting CO2 emissions as Enel's largest project to date.

 

Key Points

A 500 MW Enel wind project in Texas, supplying renewable power via PPAs and hedged by a Proxy Revenue Swap.

✅ 450 MW online; expanding to 500 MW in early 2020

✅ 12-year PPA with Danone North America for 20.6 MW

✅ PRS hedge with Allianz and Nephila stabilizes revenues

 

Enel, through its US renewable subsidiary Enel Green Power North America, Inc. (“EGPNA”), has started operations of its 450 MW High Lonesome wind farm in Upton and Crockett Counties, in Texas, the largest operational wind project in the Group’s global renewable portfolio, alongside a recent 90 MW Spanish wind build in its European pipeline. Enel also signed a 12-year, renewable energy power purchase agreement (PPA) with food and beverage company Danone North America, a Public Benefit Corporation, for physical delivery of the renewable electricity associated with 20.6 MW, leading to an additional 50 MW expansion of High Lonesome that will increase the plant’s total capacity to 500 MW. The construction of the 50 MW expansion is currently underway and operations are due to start in the first quarter of 2020.

“The start of operations of Enel’s largest wind farm in the world marks a significant achievement for our company and reinforces our global commitment to accelerated renewable energy growth,” said Antonio Cammisecra, CEO of Enel Green Power, referencing the largest wind project constructed in North America as evidence of market momentum. “This milestone is matched with a new partnership with Danone North America to support their renewable goals, a reinforcement of our continued commitment to provide customers with tailored solutions to meet their sustainability goals.”

The agreement between Enel and Danone North America will provide enough electricity to produce the equivalent of almost 800 million cups of yogurt1 and over 80 million gallons2 of milk each year and support the food and beverage company’s commitment to securing 100% of its purchased electricity from renewable sources by 2030, in a market where North Carolina’s first wind farm is now fully operational and expanding access to clean power.

Mariano Lozano, president and CEO of Danone North America, added:“This is an exciting and significant step as we continue to advance our 2030 renewable electricity goals. As a public benefit corporation committed to balancing the needs of our business with those of society and the planet, we truly believe that this agreement makes sense from both a business and sustainability point of view. We’re delighted to be working with Enel Green Power to expand their High Lonesome wind farm and grow the renewable electricity infrastructure, such as New York’s biggest offshore wind projects, here in the US.”

In addition, as more US wind projects come online, such as TransAlta’s 119 MW project, the energy produced by a 295 MW portion of the project will be hedged under a Proxy Revenue Swap (PRS) with insurer Allianz Global Corporate & Specialty, Inc.'s Alternative Risk Transfer unit (Allianz), and Nephila Climate, a provider of weather and climate risk management products. The PRS is a financial derivative agreement designed to produce stable revenues for the project regardless of power price fluctuations and weather-driven intermittency, hedging the project from this kind of risk in addition to that associated with price and volume.

Under the PRS agreement, and as other projects begin operations, like Building Energy’s latest plant, High Lonesome will receive fixed payments based on the expected value of future energy production, with adjustments paid depending on how the realized proxy revenue of the project differs from the fixed payment. The PRS for High Lonesome, which is the largest by capacity for a single plant globally and the first agreement of its kind for Enel, was executed in collaboration with REsurety, Inc.

The investment in the construction of the 500 MW plant amounts to around 720 million US dollars. The wind farm is due to generate around 1.9 TWh annually, comparable to a 280 MW Alberta wind farm’s output, while avoiding the emission of more than 1.2 million tons of CO2 per year.

South Africa's Eskom could buy less power from wind farms during lockdown

Eskom Wind Power Curtailment reflects South Africa's lockdown-driven drop in electricity demand, prompting grid-balancing measures as Eskom signals reduced IPP procurement from renewable energy projects during low-demand hours, despite guarantees and flexible generation constraints.

 

Key Points

A temporary reduction of wind IPP purchases by Eskom to balance surplus grid capacity during the COVID-19 lockdown slump

✅ Demand drop of 7,500 MW reduced need for variable renewables.

✅ Curtailment likely during low-demand early-morning hours.

✅ IPP revenues protected via contract extensions and guarantees.

 

South African state utility Eskom has told independent wind farms that it could buy less of their power in the coming days, as electricity demand has plummeted during a lockdown, reflecting the Covid-19 impact on renewables worldwide, aimed at curbing the spread of the coronavirus.

Eskom, which is mired in a financial crisis and has struggled to keep the lights on in the past year, said on Tuesday that power demand had dropped by more than 7,500 megawatts since the lockdown started on Friday and that it had taken offline some of its own generators.

The utility supplements its generating capacity, which is mainly derived from coal, by buying power from solar and wind farms, as wind becomes a competitive source of electricity globally, under contracts signed as part of the government’s renewable energy programme.

Spokesman Sikonathi Mantshantsha said Eskom had not yet curtailed power procurement from wind farms but that it had told them, echoing industry warnings on wind investment risk seen by the sector, this could happen “for a few hours a day during the next few days, perhaps until the lockdown is lifted”.

“Most of them are able to feed power into the grid in the early hours of the day. That coincides with the lowest demand period and can highlight curtailment challenges when supply exceeds need. And we now have a lot more capacity than needed,” Mantshantsha said.

During the lockdown imposed by President Cyril Ramaphosa, businesses apart from those deemed “essential services” are closed, mirroring Spanish wind factory closures elsewhere. Many power-hungry mines and furnaces have suspended operations.

Eskom has relatively little of its own “flexible generation” capacity, which can be ramped up or down easily, unlike regions riding a renewables boom in South Australia to export power.

The government has committed to buy up to 200 billion rand ($11.1 billion) of electricity from independent power producers and has issued state guarantees for those purchases.

“They will be compensated for their losses, amid U.S. utility-solar slowdowns being reported - each day lost will be added to their contracts,” Mantshantsha said of the wind farms. “In the end they will not be worse off.”

Experts warn Albertans to lock in gas and electricity rates as prices set to soar

Alberta Energy Price Spike signals rising electricity and natural gas costs; lock in fixed rates as storage is low, demand surged in heat waves, and exports rose after Hurricane Ida, driving volatility and higher futures.

 

Key Points

An anticipated surge in Alberta electricity and natural gas prices, urging consumers to lock fixed rates to reduce risk.

✅ Fixed-rate gas near $3.79/GJ vs futures approaching $6/GJ

✅ Low storage after heat waves and U.S. export demand

✅ Switch providers or plans; UCA comparison tool helps

 

Energy economists are warning Albertans to review their gas and electricity bills and lock in a fixed rate if they haven't already done so because prices are expected to spike in the coming months.

"I have been urging anyone who will listen that every single Albertan should be on a fixed rate for this winter," University of Calgary energy economist Blake Shaffer said Monday. "And I say that for both natural gas and power."

Shaffer said people will rightly point out energy costs make up only roughly a third of their monthly bill. The rest of the costs for such things as delivery fees can't be avoided. 

But, he said, "there is an energy component and it is meaningful in terms of savings." 

For example, Shaffer said, when he checked last week, a consumer could sign a fixed rate gas contract for $3.79 a gigajoule and the current future price for gas is nearly $6 a gigajoule.

A typical household would use about 15 gigajoules a month, he said, so a consumer could save $30 to $45 a month for five months. For people on lower or fixed incomes, "that is a pretty significant saving."

Comparable savings can also be achieved with electricity, he said.

Shaffer said research has shown households that are least able to afford sharp increases in gas and electrical bills are less likely to pick up the phone and call their energy provider and either negotiate a lower fixed rate contract or jump to a new provider. 

But, he said, it is definitely worth the time and effort, particularly as Calgary electricity bills are rising across the city. Alberta's Utilities Consumer Advocate has a handy cost comparison tool on its website that allows consumers to conduct regional price comparisons that will assist in making an informed decision.

"Folks should know that for most providers you can change back to a floating rate any time you want," Shaffer said.

Summer heat wave affected natural gas supply
Why are energy prices set to spike in Alberta, which is a major producer of natural gas?

Sophie Simmonds, managing director of the brokerage firm Anova Energy, said Alberta is now generating the majority of its power using natural gas. 

The heat wave in June and July created record electrical demand. Normally, natural gas is stored in the summer for use in the winter. But this year, there was much greater gas consumption in the summer and so less was stored. 

Alberta also set a new electricity usage record during a recent deep freeze, underscoring system stress.

On top of that, Alberta has been exporting much more natural gas to the United States since August and September because Hurricane Ida knocked out natural gas assets in the Gulf of Mexico.

"So what this means is we are actually going into winter with very, very low storage numbers," Simmonds said.

Why natural gas prices have surged to some of their highest levels in years
Canadians to remain among world's top energy users even as government strives for net zero
Consultant Matt Ayres said he believes rising electricity prices also are being affected by Alberta's transition from carbon-intensive fuel sources to less carbon-intensive fuel sources.

"That transition is not always smooth," said Ayres, who is also an adjunct assistant professor at the University of Calgary's School of Public Policy. 

"It is my view that at least some of the price increases we are seeing on electricity comes down to difficulties imposed by that transition and also by a reduction in competition amongst generators, as well as power market overhaul debates shaping policy." 

In 2019, under the leadership of Premier Jason Kenney the UCP government removed the former NDP government's rate cap on electricity at the time.

The NDP has called for the government to reinstate the cap but the UCP government has dismissed that as unsustainable and unrealistic.
