SDG&E Ramona Microgrid delivers renewable energy and battery storage for wildfire mitigation, grid resilience, and PSPS support, powering the Cal Fire Air Attack Base with a 500 kW, 2,000 kWh lithium-ion system during outages.

 

Key Points

A renewable, battery-backed microgrid powering Ramona's Air Attack Base, boosting wildfire response and PSPS resilience.

✅ 500 kW, 2,000 kWh lithium-ion storage replaces diesel

✅ Keeps Cal Fire and USFS aircraft operations powered

✅ Supports PSPS continuity and rural water reliability

 

It figures to be another dry year — with the potential to spark wildfires in the region. But San Diego Gas & Electric just completed a renewable energy upgrade to a microgrid in Ramona that will help firefighters and reduce the effects of power shutoffs to backcountry residents.

The microgrid will provide backup power to the Ramona Air Attack Base, helping keep the lights on during outages, home to Cal Fire and the U.S. Forest Service's fleet of aircrafts that can quickly douse fires before they get out of hand.

"It gives us peace of mind to have backup power for a critical facility like the Ramona Air Attack Base, especially given the fact that fire season in California has become year-round," Cal Fire/San Diego County Fire Chief Tony Mecham said in a statement.

The air attack base serves as a hub for fixed-wing aircraft assigned to put out fires. Cal Fire staffs the base throughout the year with one two airtankers and one tactical aircraft. The base also houses the Forest Service's Bell 205 A++ helicopter and crew to protect the Cleveland National Forest. Aircraft for both CalFire and the Forest Service can also be mobilized to help fight fires throughout the state.

This summer, the Ramona microgrid won't have to rely on diesel generation. Instead, the facility next to the town's airport will be powered by a 500 kilowatt and 2,000 kilowatt-hour lithium-ion battery storage system that won't generate any greenhouse gas emissions.

"What's great about it, besides that it's a renewable resource, is that it's a permanent installation," said Jonathan Woldemariam, SDG&E's director of wildfire mitigation and vegetation management. "In other words, we don't have to roll a portable generator out there. It's something that can be leveraged right there because it's already installed and ready to go."

Microgrids have taken on a larger profile across the state because they can operate independently of the larger electric grid, where repairing California's grid is an ongoing challenge, thus allowing small areas or communities to keep the power flowing for hours at a time during emergencies.

That can be crucial in wildfire-prone areas affected by Public Safety Power Shutoffs, or PSPS, the practice in which investor-owned utilities in California de-energize electrical power lines in a defined area when conditions are dry and windy in order to reduce the risk of a power line falling and igniting a wildfire, while power grid upgrades move forward statewide.

Rural and backcountry communities are particularly hard hit when the power is pre-emptively cut off because many homes rely on water from wells powered by electricity for their homes, horses and livestock.

In addition to Ramona, SDG&E has established microgrids in three other areas in High Fire Threat Districts:

The microgrids in Butterfield Ranch and Shelter Valley run on diesel power but the utility plans to complete solar and battery storage systems for each locale by the end of next year, as other regions develop new microgrid rules to guide deployment.

SDG&E has a fifth microgrid in operation — in Borrego Springs, which in 2013 became the first utility-scale microgrid in the country. It provides grid resiliency to the roughly 2,700 residents of the desert town and serves as a model for integrated microgrid projects elsewhere in delivering local electricity. While the Borrego Springs microgrid is not located in a High Fire Threat District, "when and if any power is turned off, especially the power transmission feed that goes to Borrego, we can support the customers using the microgrid out there," Woldemariam said.

Microgrid costs can be higher than conventional energy systems, even as projected energy storage revenue grows over the next decade, and the costs of the SDG&E projects are passed on to ratepayers. As per California Public Utilities Commission rules, the financial details for each of microgrid are kept confidential for at least three years.

SDG&E's microgrids are part of the utility's larger plan to reduce wildfire risk that SDG&E files with the utilities commission. In its wildfire plan for 2020 through 2022, SDG&E expected to spend $1.89 billion on mitigation measures.

Six key trends that shaped Europe's electricity markets in 2020

European Electricity Market Trends 2020 highlight decarbonisation, rising renewables, EV adoption, shifting energy mix, COVID-19 impacts, fuel switching, hydro, wind and solar growth, gas price dynamics, and wholesale electricity price increases.

 

Key Points

EU power in 2020 saw lower emissions, more renewables, EV growth, demand shifts, and higher wholesale prices.

✅ Power sector CO2 down 14% on higher renewables, lower coal

✅ Renewables 39% vs fossil 36%; hydro, wind, solar expanded

✅ EV share hit 17%; wholesale prices rose with gas, ETS costs

 

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020. However, the two drivers were exceptional or seasonal.

The key trends within Europe’s electricity market include:


1. Decrease in power sector’s carbon emissions

As a result of the increase in renewables generation and decrease in fossil-fueled power generation in 2020, the power sector was able to reduce its carbon footprint by 14% in 2020. The decrease in the sector’s carbon footprint in 2020 is similar to trends witnessed in 2019 when fuel switching was the main factor behind the decarbonisation trend.

However, most of the drivers in 2020 were exceptional or seasonal (the pandemic, warm winter, high
hydro generation). However, the opposite is expected in 2021, with the first months of 2021 having relatively cold weather, lower wind speeds and higher gas prices, with stunted hydro and nuclear output also cited, developments which suggest that the carbon emissions and intensity of the power sector could rise.

The European Union is targeting to completely decarbonise its power sector by 2050 through the introduction of supporting policies such as the EU Emissions Trading Scheme, the Renewable Energy Directive and legislation addressing air pollutant emissions from industrial installations, with expectations that low-emissions sources will cover most demand growth in the coming years.

According to the European Environment Agency, Europe halved its power sector’s carbon emissions in 2019 from 1990 levels.


2. Changes in energy consumption

EU consumption of electricity fell by -4% as majority of industries did not operate at full level during the first half of 2020. Although majority of EU residents stayed at home, meaning an increase in residential energy use, rising demand by households could not reverse falls in other sectors of the economy.

However, as countries renewed COVID-19 restrictions, energy consumption during the 4th quarter was closer to the “normal levels” than in the first three quarters of 2020. 

The increase in energy consumption in the fourth quarter of 2020 was also partly due to colder temperatures compared to 2019 and signs of surging electricity demand in global markets.


3. Increase in demand for EVs

As the electrification of the transport system intensifies, the demand for electric vehicles increased in 2020 with almost half a million new registrations in the fourth quarter of 2020. This was the highest figure on record and translated into an unprecedented 17% market share, more than two times higher than in China and six times higher than in the United States.

However, the European Environment Agency (EEA)argues that the EV registrations were lower in 2020 compared to 2019. EEA states that in 2019, electric car registrations were close to 550 000 units, having reached 300 000 units in 2018.


4. Changes in the region’s energy mix and increase in renewable energy generation

The structure of the region’s energy mix changed in 2020, according to the report.

Owing to favorable weather conditions, hydro energy generation was very high and Europe was able to expand its portfolio of renewable energy generation such that renewables (39%) exceeded the share of fossil fuels (36%) for the first time ever in the EU energy mix.

Rising renewable generation was greatly assisted by 29 GW of wind and solar capacity additions in 2020, which is comparable to 2019 levels. Despite disrupting the supply chains of wind and solar resulting in project delays, the pandemic did not significantly slow down renewables’ expansion.

In fact, coal and lignite energy generation fell by 22% (-87 TWh) and nuclear output dropped by 11% (-79 TWh). On the other hand, gas energy generation was not significantly impacted owing to favorable prices which intensified coal-to-gas and lignite-to-gas switching, even as renewables crowd out gas in parts of the market.


5. Retirement of coal energy generation intensify

 As the outlook for emission-intensive technologies worsens and carbon prices rise, more and more early coal retirements have been announced. Utilities in Europe are expected to continue transitioning from coal energy generation under efforts to meet stringent carbon emissions reduction targets and as they try to prepare themselves for future business models that they anticipate to be entirely low-carbon reliant.

6. Increase in wholesale electricity prices

In recent months, more expensive emission allowances, along with rising gas prices, have driven up wholesale electricity prices on many European markets to levels last seen at the beginning of 2019. The effect was most pronounced in countries that are dependent on coal and lignite. The wholesale electricity prices dynamic is expected to filter through to retail prices.

The rapid sales growth in the EVs sector was accompanied by expanding charging infrastructure. The number of high-power charging points per 100 km of highways rose from 12 to 20 in 2020.

Australia stuck in the middle of the US and China as tensions rise

Manus Island Naval Base strengthens US-Australia-PNG cooperation at Lombrum, near the South China Sea, bolstering sovereignty, maritime rights, and Pacific security amid APEC talks, infrastructure investment, and Belt and Road competition.

 

Key Points

A US-Australia-PNG facility at Lombrum to bolster Pacific security and protect maritime rights across the region.

✅ Shared by US, Australia, and PNG at Lombrum on Manus Island

✅ Near South China Sea, reinforcing maritime security and access

✅ Counters opaque lending, aligns with free trade and infrastructure

 

Scott Morrison has caught himself bang in the middle of escalating tensions between the United States and China.

The US and Australia will share a naval base in the north end of Papua New Guinea on Manus Island, creating another key staging point close to the contested South China Sea.

“The United States will partner with Papua New Guinea and Australia on their joint initiative at Lombrum Naval Base,” US Vice President Mike Pence said.

“We will work with these two nations to protect sovereignty and maritime rights in the Pacific Islands. ”

At an Asia Pacific Economic Cooperation meeting in Port Moresby on Saturday, Mr Morrison urged nations to embrace free trade and avoid “unsustainable debt”, as the Philippines' clean energy commitment also featured in discussions.

He confirmed the US and Australia will share an expanded naval base on Manus Island, as the US ramped up rhetoric against China.

Mr Pence quoted President Donald Trump in his speech following Chinese President Xi Jinping, even as a Biden energy agenda is seen by some as better for Canada.

“We have great respect for President Xi and respect for China. But in the president’s words, China’s taken advantage of the United States for many, many years,” he said.

“And those days are over.”

His speech was met with stony silence from the Chinese delegation, after President Xi had reassured leaders his Belt and Road Initiative was not a debt trap.

China has also been at loggerheads with the United States over its territorial ambitions in the Pacific, encapsulated by Xi’s Belt and Road Initiative.

Unveiled in 2013, the Belt and Road initiative aims to bolster a sprawling network of land and sea links with Southeast Asia, Central Asia, the Middle East, Europe and Africa.

China’s efforts to win friends in the resource-rich Pacific have been watched warily by the traditionally influential powers in the region — Australia and the United States.

“It is not designed to serve any hidden geopolitical agenda,” President Xi said on Saturday.

“Nor is it a trap, as some people have labelled it.”

But Mr Pence said loans to developing countries were too often opaque and encouraged nations to look to the US instead of China.

“Too often they come with strings attached and lead to staggering debt,” he said in his speech.

“Do not accept foreign debt that could compromise your sovereignty.

“Just like America, always put your country first.”

Mr Morrison committed Australia to look to the Pacific nations and on Sunday he will host an informal BBQ with Pacific leaders, amid domestic moves like Western Australia's electricity bill credit for households.

He also announced a joint partnership with Japan and the US to fund infrastructure around the region, while at home debates over an electricity market overhaul continue.

On the back of Mr Morrison’s defence of free trade at the summit, Australian Trade Minister Simon Birmingham said he was confident the US was interested in an open trading environment in the long run, with parallel discussions such as a U.S.-Canada energy partnership underscoring regional economic ties.

Australia is hoping the US will, in the end, take a similar approach to its trade dispute with China as it did with its tariff threats against Mexico and Canada, as cross-border negotiations like the Columbia River Treaty continue to shape U.S.-Canada ties.

“Ultimately, they laid down arms, they walked away from threats, and they struck a new trade deal that ensures trade continues in that North American bloc,” Mr Birmingham told ABC TV on Sunday.

“We hope the same will happen in relation to China.”

Four countries including the US have signed up to an effort to bring electricity to 70 per cent of Papua New Guinea’s people by 2030.

Australia, Japan, the US and New Zealand on Sunday signed an agreement to work with Papua New Guinea’s government on electrification.

It’s the latest sign of great power rivalry in the South Pacific, where China is vying with the US and its allies for influence.

New Electricity Auctions Will Drive Down Costs for Ontario's Consumers

IESO Capacity Auctions will competitively procure resources for Ontario electricity needs, boosting reliability and resource adequacy through market-based bidding, enabling demand response, energy storage, and flexible supply to meet changing load and regional grid conditions.

 

Key Points

A competitive, technology-neutral auction buys capacity at lowest cost to keep Ontario's grid reliable and flexible.

✅ Market-based procurement reduces system costs.

✅ Enables demand response, storage, and hybrid resources.

✅ Increases flexibility and regional reliability in Ontario.

 

The Independent Electricity System Operator (IESO) is introducing changes to Ontario's electricity system that will help save Ontarians about $3.4 billion over a 10-year period. The changes include holding annual capacity auctions to acquire electricity resources at lowest cost that can be called upon when and where they are needed to meet Ontario electricity needs. 

Today's announcement marks the release of a high level design for future auctions, with changes for electricity consumers expected as the first is set to be held in late 2022.

"These auctions will specify how much electricity we need, and introduce a competitive process to determine who can meet that need. It's a competition among all eligible resources, and it's the Ontario consumer, including industrial electricity ratepayers, who benefits through lower costs and a more flexible system better able to respond to changing demand and supply conditions," says IESO President and CEO Peter Gregg.

In the past decade, electricity supply was typically acquired through very prescriptive means with defined targets for specific types of resources such as wind and solar, and secured through 20-year contracts.  While these long-term commitments helped Ontario transform its generation fleet over the last decade, electricity cost allocation also played a role, but longer term contracts provide limited flexibility in dealing with unexpected changes in the power system. 

"Imagine signing a 20-year contract for your cable TV service. In five years' time, electricity rates could be lower, new competitors may have entered the market, or entirely new and innovative platforms and services like Netflix may have emerged. You miss out on opportunities for improvement by being locked-in," says Gregg.

Provincial electricity demand has traditionally fluctuated over time due to factors like economic growth, conservation and the introduction of generating resources on local distribution systems, with occasional issues such as phantom demand affecting customers' costs as well. Technological changes are adding another layer of uncertainty to future demand as electric vehicles, energy storage and low-cost solar panels become more common.

"Our planners do their best to forecast electricity demand, but the truth is there's no such thing as certainty in electricity planning. That's why flexibility is so important. We don't want Ontarians to have to pay more on the typical Ontario electricity bill for electricity resources than are needed to ensure a reliable power system that can continue to meet Ontario's needs," says IESO Vice President and COO Leonard Kula.

FPL stages massive response to Irma but power may not be back for days or weeks

FPL Power Restoration mobilizes Florida linemen and mutual-aid utility crews to repair the grid, track outages with smart meters, prioritize hospitals and essential services, and accelerate hurricane recovery across the state.

 

Key Points

FPL Power Restoration is the utility's hurricane effort to rebuild the grid and quickly restore service across Florida.

✅ 18,000 mutual-aid utility workers deployed from 28 states

✅ Smart meters pinpoint outages and accelerate repairs

✅ Critical facilities prioritized before neighborhood restorations

 

Teams of Florida Power & Light linemen, assisted by thousands of out-of-state utility workers and 200 Ontario workers who joined the effort, scrambled across Florida Monday to tackle the Herculean task of turning the lights back on in the Sunshine State.

The job is quite simply mind-boggling as Irma caused extensive damages to the power grid and the outages have broken previous records, and in other storms Louisiana's grid needed a complete rebuild after Hurricane Laura to restore service.

By 3 p.m. Monday, some 3.47 million of the company's 4.9 million customers in Florida were without power. This breaks the record of 3.24 million knocked off the grid during Hurricane Wilma in 2005, according to FPL spokesman Bill Orlove.

Prepared to face massive outages, FPL brought some 18,000 utility workers from 28 states here to join FPL crews, including Canadian power crews arriving to help restore service, to enable them to act more quickly.

“That’s the thing about the utility industry,” said  Alys Daly, an FPL spokeswoman. “It’s truly a family.”

Even with what is believed to be the largest assembly of utility workers ever assembled for a single storm in the United States, power restoration is expected to take weeks, not days in some areas.

FPL vowed to work as quickly as possible as they assess the damage and send out crews to restore power.

"We understand that people need to have power right away to get their lives back to normal," Daly said.

The priority, she said, were medical and emergency management facilities and then essential service providers like gas stations and grocery stores.

After that, FPL will endeavor to repair the problems that will restore power to the maximum number of people possible. Then it's individual neighborhoods.

As of 3 p.m. Monday, 219,040 of FPL's 307,600 customers on the Space Coast had no power. That's an improvement over the 260,600 earlier in the day.

Daly was unable to say Monday how many crews FPL had working in Brevard County. In some areas, power came back relatively swiftly, much quicker than expected.

" I was definitely surprised at how quickly they got our power back on here in NE Palm Bay," said Kelli Coats. "We lost power last night around 9 p.m Sunday and regained power around 8:30 a.m. today."

Others, many of them beachside, were looking at a full 24 hours without power and it's possible it could extend into Tuesday or longer.

One reason for improved response times since 2005, Daly said, is the installation of nearly 5 million "Smart Meters" at residences. These new devices, which replaced older analog models, allows FPL crews to track a neighborhood's power status via handheld computers, pinpointing the cause of an outage so it can be repaired.

Quick restoration is key as stores and restaurants struggle to re-open, and Gulf Power crews restored power in the early push. Without electricity many of them just can't re-start operations and get goods and services to consumers.

At the Atlanta-based Waffle House, which Federal Emergency Management Administration use to gauge the severity of damage and service to an area, restaurant executives are reviewing its operations in Florida and should have a better handle Monday afternoon how quickly restaurants will re-open.

"Right now, we're in an assessment phase," said Pat Warner, spokesman for Waffle House. "We're looking at which stores have power and which ones have damage."

FEMA's color-coded Waffle House Index started after the hurricanes in the early 2000s. It works like this: When an official phones a Waffle House to see if it is open,  the next stop is to assess it's level of service. If it's open and serving a full menu, the index is green. When the restaurant is open but serving a limited menu, it's yellow. When it's closed, it's red.

Ontario Provides Stable Electricity Pricing for Industrial and Commercial Companies

Ontario ICI Electricity Pricing Freeze helps Industrial Conservation Initiative (ICI) participants by stabilizing Global Adjustment charges, suspending peak hours curtailment, and reducing COVID-19-related electricity cost volatility to support large employers returning operations to full capacity.

 

Key Points

A two-year policy stabilizing GA costs and pausing peak-hour cuts to aid industrial and commercial recovery.

✅ GA cost share frozen for two years

✅ No peak-hour curtailment obligations

✅ Supports industrial and commercial restart

 

The Ontario government is helping large industrial and commercial companies return to full levels of operation without the fear of electricity costs spiking by providing more stable electricity pricing for two years. Effective immediately, companies that participate in the Industrial Conservation Initiative (ICI) will not be required to reduce their electricity usage during peak hours or shift some load to ultra-low overnight pricing where applicable, as their proportion of Global Adjustment (GA) charges for these companies will be frozen.

"Ontario's industrial and commercial electricity consumers continue to experience unprecedented economic challenges during COVID-19, with electricity relief for households and small businesses introduced to help," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Today's announcement will allow large industrial employers to focus on getting their operations up and running and employees back to work, instead of adjusting operations in response to peak electricity demand hours."

Due to COVID-19, electricity consumption in Ontario has been below average as fall in demand as people stayed home across the province, and the province is forecast to have a reliable supply of electricity, supported by the system operator's staffing contingency plans during the pandemic, to accommodate increased usage. Peak hours generally occur during the summer when the weather is hot and electricity demand from cooling systems is high.

"Today's action will reduce the burden of anticipating and responding to peak hours for more than 1,300 ICI participants with 2,000 primarily industrial facilities in Ontario," said Bill Walker, Associate Minister of Energy. "Now these large employers can focus on getting their operations back up and running at full tilt and explore new energy-efficiency programs to manage costs."

The government previously announced it was providing temporary relief for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan (RPP) by deferring a portion of GA charges for April, May and June 2020 and by extending off-peak rates for many customers, as well as a disconnect moratorium extension for residential electricity users.

What 2018 Grid Edge Trends Reveal About 2019

2019 Grid Edge Trends highlight evolving demand response, DER orchestration, real-time operations, AMI data, and EV charging, as wholesale markets seek flexibility and resiliency amid tighter reserve margins and fossil baseload retirements.

 

Key Points

Shifts toward DER-enabled demand response and real-time, behind-the-meter flexibility.

✅ Real-time DER dispatch enhances reliability during tight reserves

✅ AMI and ICT improve forecasting, monitoring, and control of resources

✅ Demand response shifts toward aggregated behind-the-meter orchestration

 

Which grid edge trends will continue into 2019 as the digital grid matures and what kind of disruption is on the horizon in the coming year?

From advanced metering infrastructure endpoints to electric-vehicle chargers, grid edge venture capital investments to demand response events, hundreds of data points go into tracking new trends at the edge of the grid amid ongoing grid modernization discussions across utilities.

Trends across these variables tell a story of transition, but perhaps not yet transformation. Customers hold more power than ever before in 2019, with utilities and vendors innovating to take advantage of new opportunities behind the meter. Meanwhile, external factors can always throw things off-course, including the data center boom that is posing new power challenges, and reliability is top of mind in light of last year's extreme weather events. What does the 2018 data say about 2019?

For one thing, demand response evolved, enabled by new information and communications technology. Last year, wholesale market operators increasingly sought to leverage the dispatch of distributed energy resource flexibility in close to real time. Three independent system operators and regional transmission organizations called on demand response five times in total for relief in the summer of 2018, including the NYISO.

The demand response events called in the last 18 months send a clear message: Grid operators will continue to call events year-round. This story unfolds as reserve margins continue to tighten, fossil baseload generation retirements continue, and system operators are increasingly faced with proving the resiliency and reliability of their systems while efforts to invest in a smarter electricity infrastructure gain momentum across the country.

In 2019, the total amount of flexible demand response capacity for wholesale market participation will remain about the same. However, the way operators and aggregators are using demand response is changing as information and communications technology systems improve and utilities are using AI to adapt to electricity demands, allowing the behavior of resources to be more accurately forecasted, monitored and controlled.

These improvements are allowing customer-sited resources to offer  flexibility services closer to real-time operations and become more reactive to system needs. At the same time, traditional demand response will continue to evolve toward the orchestration of DERs as an aggregate flexible resource to better enable growing levels of renewable energy on the grid.
