London Gateway Unveils World’s First All-Electric Berth

Duke Energy Carolinas Solar RFP draws 3.9 GW of utility-scale bids, oversubscribed in DEP and DEC, below avoided cost rates, minimal battery storage, strict PPA terms, and interconnection challenges across North and South Carolina.

Key Points

Utility-scale solar procurement in DEC and DEP, evaluated against avoided cost, with few storage bids and PPA terms.

✅ 3.9 GW bids for 680 MW; DEP most oversubscribed

✅ Most projects 7-80 MWac; few include battery storage

✅ Bids must price below 20-year avoided cost estimate

Last week the independent administrator for Duke’s 680 MW solar solicitation revealed data about the projects which have bid in response to the offer, showing a massive amount of interest in the opportunity.

Overall, 18 individuals submitted bids for projects in Duke Energy Carolinas (DEC) territory and 10 in Duke Energy Progress (DEP), with a total of more than 3.9 GW of proposals – more nearly 6x the available volume. DEP was relatively more over-subscribed, with 1.2 GWac of projects vying for only 80 MW of available capacity.

This is despite a requirement that such projects come in below the estimate of Duke’s avoided cost for the next 20 years, and amid changes in solar compensation that could affect project economics. Individual projects varied in capacity from 7-80 MWac, with most coming within the upper portion of that range.

These bids will be evaluated in the spring of 2019, and as Duke Energy Renewables continues to expand its portfolio, Duke Energy Communications Manager Randy Wheeless says he expects the plants to come online in a year or two.

Lack of storage

Despite recent trends in affordable batteries, of the 78 bids that came in only four included integrated battery storage. Tyler Norris, Cypress Creek Renewables’ market lead for North Carolina, says that this reflects that the methodology used is not properly valuing storage.

“The lack of storage in these bids is a missed opportunity for the state, and it reflects a poorly designed avoided cost rate structure that improperly values storage resources, commercially unreasonable PPA provisions, and unfavorable interconnection treatment toward independent storage,” Norris told pv magazine.

“We’re hopeful that these issues will be addressed in the second RFP tranche and in the current regulatory proceedings on avoided cost and state interconnection standards and grid upgrades across the region.”

Limited volume for North Carolina?

Another curious feature of the bids is that nearly the same volume of solar has been proposed for South Carolina as North Carolina – despite this solicitation being in response to a North Carolina law and ongoing legal disputes such as a church solar case that challenged the state’s monopoly model.

Alberta Coal-to-Gas Transition will retire coal units, convert plants to natural gas, boost renewables, and affect electricity prices, with policy tools like a price cap and carbon tax shaping the power market.

Key Points

Shift retiring coal units and converting to natural gas and renewables, targeting coal elimination by 2030.

✅ TransAlta retires Sundance coal unit; more units convert to gas.

✅ Forward prices seen near $40 to low $50/MWh in 2018.

✅ 6.8-cent cap shields consumers; carbon tax backstops costs.

The turn of the calendar to 2018 saw TransAlta retire one of its coal power generating units at its Sundance plant west of Edmonton and mothball another as it begins the transition to cleaner sources of energy across Alberta.

The company will say goodbye to three more units over the next year and a half to prepare them for conversion to natural gas.

This is part of a fundamental shift in Alberta, which will see coal power retired ahead of schedule by 2030, replaced by a mix of natural gas and renewable sources.

“We’re going to see that transition continue right up from now until 2030, and likely beyond 2030 as wind generation starts to outpace coal and new technologies become available.”

Coal has long been the backbone of Alberta’s grid, currently providing nearly 40 per cent of the provinces power. Analysts believe removing it will come with a cost to consumers, according to a report on coal phase-out costs published recently.

“The open question over the next couple of years is whether they’re going to inch up gradually, or whether they’re going to inch up like they did in 2012 and 2013, by having periods of very high power prices.”

Albertans are currently paying historically low power prices, with generation costs last year averaging below $23/MWh, less than half of the average of the past 10 years.

A report released in mid-December by electricity consultant firm EDC Associates showed forward prices moving from the $40/MWh in the first three months of 2018, to the low $50/MWh range.

“The forwards tend to take several weeks to fully react to announcements, so its anticipated that prices will continue to gradually track upwards over the coming weeks,” the report reads.

The NDP government has taken steps to protect consumers against price surges. Last spring, a price cap of 6.8 cents/MWh was put in place until the spring of 2021, with any cost above that to be covered by carbon tax revenue.

California Heat Wave Grid Emergency sees CAISO issue Stage 3 alerts as record demand, extreme heat, and climate change strain renewable energy; conservation efforts avert rolling blackouts and protect grid reliability statewide.

Key Points

A grid emergency in California's heat wave, with CAISO Stage 3 alerts amid record demand and risk of rolling blackouts.

✅ CAISO triggered Stage 3 alerts, then downgraded by 8 pm PT

✅ Record 52,061 MW demand; conservation reduced grid stress

✅ Extreme heat and climate change heightened outage risks

California has avoided ordering rolling blackouts after electricity demand reached a record-high Tuesday night from excessive heat across the state, even as energy experts warn the U.S. grid faces mounting climate stresses. 

The California Independent System Operator, which oversees the state’s electrical grid, imposed its highest level energy emergency on Tuesday, a step that comes before ordering rolling blackouts and allows the state to access emergency power sources.

The Office of Emergency Services also sent a text alert to residents requesting them to conserve power. The operator downgraded the Stage 3 alert around 8:00 p.m. PT on Tuesday and said that “consumer conservation played a big part in protecting electric grid reliability,” and in bolstering grid resilience overall.

The state capital of Sacramento reached 116 degrees Fahrenheit on Tuesday, according to the National Weather Service, surpassing a record that was set almost 100 years ago. And nearly a half-dozen cities in the San Francisco Bay Area tied or set all-time highs, the agency said.

CAISO said peak power demand on Tuesday reached 52,061 megawatts, surpassing a previous high of 50,270 megawatts on July 24, 2006, while nearby B.C. electricity demand has also hit records during extreme weather.

While the operator did not order rolling blackouts, three Northern California cities saw brief power outages, and severe storms have caused similar disruptions statewide in recent months. As of 7:00 am PT on Wednesday, nearly 8,000 customers in California were without power, according to PowerOutage.us. 

Gov. Gavin Newsom, in a Twitter video on Tuesday, warned the temperatures across California were unprecedented and the state is headed into the worst part of the heat wave, which is on track to be the hottest and longest on record for September.

“The risk for outages is real and it’s immediate,” Newsom said. “These triple-digit temperatures throughout much of the state are leading, not surprisingly, to record demand on the energy grid.”

The governor urged residents to pre-cool their homes earlier in the day when more power is available and turn thermostats to 78 degrees or higher after 4:00 pm PT. “Everyone has to do their part to help step up for just a few more days,” Newsom said.

The possibility for widespread outages reflects how power grids in California and other states are becoming more vulnerable to climate-related disasters such as heat waves, storms and wildfires across California.

California, which has set a goal to transition to 100% carbon-free electricity by 2045, has shuttered a slew of gas power plants in the past few years, leaving the state increasingly dependent on solar energy.

At times, the state has produced a clean energy surplus during peak solar generation, underscoring the challenges of balancing supply and demand.

The megadrought in the American West has generated the driest two decades in the region in at least 1,200 years, and human-caused climate change has fueled the problem, scientists said earlier this year. Conditions will likely continue through 2022 and persist for years.

Ukraine Energy Grid Attacks intensify as missile strikes and drone raids hit power plants, substations, and transmission lines, causing blackouts, disrupted logistics, and humanitarian strain during winter, despite repairs, air defense, and allied aid.

Key Points

Missile and drone strikes on Ukraine's power grid to force blackouts, strain civilians, and disrupt military logistics.

✅ Targets: power plants, substations, transmission lines

✅ Impacts: blackouts, heating loss, hospital strain

✅ Goals: erode morale, disrupt logistics, force aid burdens

Russia’s continued strikes on Ukraine have taken a severe toll on the country’s critical infrastructure, particularly its energy grid, as Ukraine continues to keep the lights on despite sustained bombardment. In recent months, Western Ukraine has increasingly become a target of missile and drone attacks, leading to widespread power outages and compounding the challenges faced by the civilian population. These strikes aim to cripple Ukraine's resilience during a harsh winter season and disrupt its wartime operations.

Targeting Energy Infrastructure

Russian missile and drone assaults on Ukraine’s energy grid are part of a broader strategy to weaken the country’s morale and capacity to sustain the war effort. The attacks have primarily focused on power plants, transmission lines, and substations. Western Ukraine, previously considered a relative safe haven due to its distance from front-line combat zones, is now experiencing the brunt of this campaign.

The consequences of these strikes are severe. Rolling blackouts and unplanned outages have disrupted daily life for millions of Ukrainians, though authorities say there are electricity reserves that could stabilize supply if no new strikes occur, leaving homes without heating during freezing temperatures, hospitals operating on emergency power, and businesses struggling to maintain operations. The infrastructure damage has also affected water supplies and public transportation, further straining civilian life.

Aimed at Civilian and Military Impact

Russia’s targeting of Ukraine’s power grid has dual purposes. On one hand, it aims to undermine civilian morale by creating hardships during the cold winter months, even as Ukraine works to keep the lights on this winter through contingency measures. On the other, it seeks to hinder Ukraine’s military logistics and operations, which heavily rely on a stable energy supply for transportation, communications, and manufacturing of military equipment.

These attacks coincide with a broader strategy of attritional warfare, where Moscow hopes to exhaust Ukraine’s resources and diminish its ability to continue its counteroffensive operations. By disrupting critical infrastructure, Russia increases pressure on Ukraine's allies to step up humanitarian and military aid, stretching their capacities.

Humanitarian Consequences

The impact of these power cuts on the civilian population is profound. Millions of Ukrainians are enduring freezing temperatures without consistent access to electricity or heating. Vulnerable populations, such as the elderly, children, and those with disabilities, face heightened risks of hypothermia and other health issues.

Hospitals and healthcare facilities are under immense strain, relying on backup generators that cannot sustain prolonged use. In rural areas, where infrastructure is already weaker, the effects are even more pronounced, leaving many communities isolated and unable to access essential services.

Humanitarian organizations have ramped up efforts to provide aid, including distributing generators, warm clothing, and food supplies, while many households pursue new energy solutions to weather blackouts. However, the scale of the crisis often outpaces the resources available, leaving many Ukrainians to rely on their resilience and community networks.

Ukraine's Response

Despite the challenges, Ukraine has demonstrated remarkable resilience in the face of these attacks. The government and utility companies are working around the clock to repair damaged infrastructure and restore power to affected areas. Mobile repair teams and international assistance have played crucial roles in mitigating the impact of these strikes.

Ukraine’s Western allies have also stepped in to provide support. The European Union, the United States, and other countries have supplied Ukraine with energy equipment, financial aid, and technical expertise to help rebuild its energy grid, though recent decisions like the U.S. ending support for grid restoration complicate planning and procurement. Additionally, advanced air defense systems provided by Western nations have helped intercept some of the incoming missiles and drones, though not all attacks can be thwarted.

Russia’s Escalation Strategy

Russia’s focus on Western Ukraine reflects a shift in its strategy. Previously, attacks were concentrated on front-line areas and major urban centers in the east and south. However, by targeting the western regions, Moscow seeks to disrupt the relatively stable zones where displaced Ukrainians and critical supply chains are located.

Western Ukraine is also a hub for receiving and distributing international aid and military supplies. Striking this region not only undermines Ukraine’s internal stability but also sends a message to its allies about Russia’s willingness to escalate the conflict further.

Broader Implications

The attacks on Ukraine’s energy grid have broader geopolitical implications. By targeting infrastructure, Russia intensifies the pressure on Ukraine’s allies to continue providing support, even as Kyiv has at times helped Spain amid blackouts when capacity allowed, testing their unity and resolve. The destruction also poses long-term challenges for Ukraine’s post-war recovery, as rebuilding a modern and resilient energy system will require significant investments and time.

Moreover, these attacks highlight the vulnerability of civilian infrastructure in modern warfare, echoing that electricity is civilization amid winter conditions. The deliberate targeting of non-combatant assets underscores the need for international efforts to strengthen the protection of critical infrastructure and address the humanitarian consequences of such tactics.

The Russian attacks on Western Ukraine's power grid are a stark reminder of the devastating human and economic costs of the ongoing conflict. While Ukraine continues to demonstrate resilience and adaptability, the scale of destruction underscores the need for sustained international support. As the war drags on, the focus must remain on mitigating civilian suffering, rebuilding critical infrastructure, and pursuing a resolution that ends the violence and stabilizes the region.

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

TransLink Electric Bus Pilot launches zero-emission service in Metro Vancouver, cutting greenhouse gas emissions with fast-charging stations on Route 100, supporting renewable energy goals alongside trolley buses, CNG, and hybrid fleets.

Key Points

TransLink's Metro Vancouver program deploying charging, zero-emission buses on Route 100 to cut emissions and fuel costs.

✅ Cuts ~100 tonnes GHG and saves $40k per bus annually

✅ Five-minute on-route charging at terminals on Route 100

✅ Pilot data to guide zero-emission fleet transition by 2050

TransLink's first battery-electric buses are taking to the roads in Metro Vancouver as part of a pilot project to reduce emissions, joining other initiatives like electric school buses in B.C. that aim to cut pollution in transportation.

The first four zero-emission buses picked up commuters in Vancouver, Burnaby and  New Westminster on Wednesday. Six more are expected to be brought in, and similar launches like Edmonton's first electric bus are underway across Canada.

"With so many people taking transit in Vancouver today, electric buses will make a real difference," said Merran Smith, executive director of Clean Energy Canada, a think tank at Simon Fraser University, in a release.

According to TransLink, each bus is expected to reduce 100 tonnes of greenhouse gas emissions and save $40,000 in fuel costs per year compared to a conventional diesel bus.

"Buses already help tackle climate change by getting people out of cars, and Vancouver is ahead of the game with its electric trolleys," Smith said.

She added there is still more work to be done to get every bus off diesel, as seen with the TTC's battery-electric buses rollout in Toronto.

The buses will run along the No. 100 route connecting Vancouver and New Westminster. They recharge — it takes about five minutes — at new charging stations installed at both ends of the route while passengers load and unload or while the driver has a short break. 

Right now, more than half of TransLink's fleet currently operates with clean technology, offering insights alongside Toronto's large battery-electric fleet for other cities. 

In addition to the four new battery-electric buses, the fleet also includes hundreds of zero-emission electric trolley buses, compressed natural gas buses and hybrid diesel-electric buses, while cities like Montreal's first STM electric buses continue to expand adoption.

"Our iconic trolley buses have been running on electricity since 1948 and we're proud to integrate the first battery-electric buses to our fleet," said TransLink CEO Kevin Desmond in a press release.

TransLink has made it a goal to operate its fleet with 100 per cent renewable energy in all operations by 2050. Desmond says, the new buses are one step closer to meeting that goal.

The new battery-electric buses are part of a two-and-a-half year pilot project that looks at the performance, maintenance, and customer experience of making the switch to electric, complementing BC Hydro's vehicle-to-grid pilot initiative underway in the province.
