Carnegie Teams with Sumitomo for Grid-Scale Vanadium Flow Battery Storage

Renewables Beat Brown Coal in Australia, as solar and wind surged to nearly 10,000 GWh, stabilizing the grid with battery storage during peak demand, after Hazelwood's closure, Green Energy Markets reported.

Key Points

It describes a 2017-18 summer when solar, wind, and storage generated more electricity than brown coal in Australia.

✅ Solar and wind hit nearly 10,000 GWh in summer 2017-18

✅ Brown coal fell to about 9,100 GWh after Hazelwood closure

✅ Batteries stabilized peak demand; Tesla responded in milliseconds

Renewable energy generated more electricity than brown coal during Australia’s summer for the first time in 2017-18, according to a new report by Green Energy Markets.

Continued growth in solar, as part of Australia's energy transition, pushed renewable generation in Australia to just under 10,000 gigawatt hours between December 2017 and February 2018. With the Hazelwood plant knocked out of the system last year, brown coal’s output in the same period was just over 9,100 GWh.

Renewables produced 40% more than gas over the period, and was exceeded only by black coal, reflecting trends seen in U.S. renewables surpassing coal in 2022.

The report, commissioned by GetUp, found renewables were generating particularly large amounts of electricity when it was most needed, producing 32% more than brown coal during summer between 11am and 7pm, when demand peaks.

Coal in decline: an energy industry on life support

Solar in particular was working to support the system, on average producing more than Hazelwood was capable of producing between 9am and 5pm.

A further 5,000 megawatts of large-scale renewables projects was under construction in February, supporting 17,445 jobs, while renewables became the second-most prevalent U.S. electricity source in 2020.

GetUp’s campaign director, Miriam Lyons, said the latest renewable energy index showed renewables were keeping the lights on while coal became increasingly unreliable, a trend echoed as renewables surpassed coal in the U.S. in recent years.

“Over summer renewables kept houses cool and lights on during peak demand times when people needed electricity most,” Lyons said. “Meanwhile dirty old coal plants are becoming increasingly unreliable in the heat.

“These ageing clunkers failed 36 times over summer.

“Clean energy rescued people from blackouts this summer. When the clapped-out Loy Yang coal plant tripped, South Australia’s giant Tesla battery reacted in milliseconds to keep the power on.

“It’s clear that a smart electricity grid based on a combination of renewable energy and storage is the best way to deliver clean, affordable energy for all Australians.”

EPA Wastewater Rule Rollback signals a move to rewrite 2015 Clean Water Act guidelines for coal-fired power plants, easing wastewater rules as heavy metals, mercury, lead, arsenic, and selenium threaten rivers, lakes, public health.

Key Points

A planned EPA rewrite of 2015 wastewater limits for coal plants, weakening protections against toxic heavy metals.

✅ Targets 2015 Clean Water Act wastewater guidelines

✅ Affects coal-fired steam electric power plants

✅ Raises risks from mercury, lead, arsenic, selenium

The Environmental Protection Agency says it plans to scrap an Obama-era measure limiting water pollution from coal-fired power plants, mirroring moves to replace the Clean Power Plan elsewhere in power-sector policy.

A letter from EPA Administrator Scott Pruitt released Monday as part of a legal appeal and amid a broader rewrite of NEPA rules said he will seek to revise the 2015 guidelines mandating increased treatment for wastewater from steam electric power-generating plants.

Acting at the behest of energy groups and electric utilities who opposed the stricter standards, Pruitt first moved in April to delay implementation of the new guidelines. The wastewater flushed from the coal-fired plants into rivers and lakes typically contains traces of such highly toxic heavy metals as lead, arsenic, mercury and selenium.

“After carefully considering your petitions, I have decided that it is appropriate and in the public interest to conduct a rulemaking to potentially revise (the regulations),” Pruitt wrote in the letter addressed to the pro-industry Utility Water Act Group and the U.S. Small Business Administration.

Pruitt’s letter, dated Friday, was filed Monday with the Fifth Circuit U. S. Court of Appeals in New Orleans, which is hearing legal challenges of the wastewater rule. With Pruitt now moving to rewrite the standards, EPA has asked to court to freeze the legal fight.

While that process moves ahead, EPA’s existing guidelines from 1982 remian in effect. Those standards were set when far less was known about the detrimental impacts of even tiny levels of heavy metals on human health and aquatic life.

“Power plants are by far the largest offenders when it comes to dumping deadly toxics into our lakes and rivers,” said Thomas Cmar, a lawyer for the legal advocacy group Earthjustice. “It’s hard to believe that our government officials right now are so beholden to big business that they are willing to let power plants continue to dump lead, mercury, chromium and other dangerous chemicals into our water supply.”

EPA estimates that the 2015 rule, if implemented, would reduce power plant pollution, consistent with new pollution limits proposed for coal and gas plants, by about 1.4 billion pounds a year. Only about 12 per cent of the nation’s steam electric power plants would have to make new investments to meet the higher standards, according to the agency.

Utilities would need to spend about $480 million on new wastewater treatment systems, resulting in about $500 million in estimated public benefits, such as fewer incidents of cancer and childhood developmental defects.

PEI Electric Vehicle Incentives aim to boost EV adoption through subsidies and rebates, advocated by Renewable Transport PEI, with MLAs engagement, modeling Norway's approach, offsetting HST gaps, and making electric cars more competitive for Islanders.

Key Points

PEI Electric Vehicle Incentives are proposed subsidies and rebates to make EVs affordable and competitive for Islanders.

✅ Targets EV adoption with rebates up to 20 percent

✅ Modeled on Norway policies; offsets prior HST-era gaps

✅ Backed by Renewable Transport PEI engaging MLAs

Noah Ellis, assistant director of Renewable Transport P.E.I., is asking government to introduce incentives for Islanders to buy electric cars, as cost barriers remain a key hurdle for many.

RTPEI is a group composed of high school students at Colonel Gray going into their final year."We wanted to give back and contribute to our community and our country and we thought this would be a good way to do so," Ellis told Compass.

Meeting with government

"We want to see the government bring in incentives for electric vehicles, similar to New Brunswick's rebate program, because it would make them more competitive with their gasoline counterparts," Ellis said.

'We wanted to give back and contribute to our community … we thought this would be a good way to do so.'— Noah Ellis

Ellis said the group has spoken with opposition MLAs and is meeting with cabinet ministers soon to discuss subsidies for Islanders to buy electric cars, noting that Atlantic Canadians are less inclined to buy EVs compared to the rest of the country.

He referred to Norway as a prime example for the province to model potential incentives, even as Labrador's EV infrastructure gaps underscore regional challenges — a country that, as of last year, announced nearly 40 per cent of the nation's newly registered passenger vehicles as electric powered.

'Incentives that are fiscally responsible'

Ellis said they group isn't looking for anything less than a 20 per cent incentive on electric vehicles — 10 per cent higher than the provinces cancelled hybrid car tax rebate that existed prior to HST.

"Electric vehicle incentives do work we just have to work with economists and environmentalists, and address critics of EV subsidies, to find the right balance of incentives that are fiscally responsible for the province but will also be effective," Ellis said.

Ireland Wind and Solar Share 2022 highlights IEA projections of over 33% electricity generation from renewables, with variable renewable energy growth, capacity targets, EU policy shifts, and investments accelerating wind and solar deployment.

Key Points

IEA forecasts wind and solar to exceed 33% of Ireland's electricity by 2022, second in variable renewables after Denmark.

✅ IEA expects Ireland to surpass 33% wind and solar by 2022

✅ Denmark leads at ~70%; Germany and UK exceed 25%

✅ Investments and capacity targets drive renewable growth

The share of wind and solar in total electricity generation in Ireland is expected to exceed 33pc by 2022, according to the 'Renewables 2017' report from the International Energy Agency (IEA).

Among the findings, the report says that Denmark is on course to be the world leader in the variable renewable energy sector, with 70pc of its electricity generation expected to come from wind and solar renewables by 2022.

The Nordic country will be followed by Ireland, Germany and the UK, all of which are expected see their share of wind and solar energy in total electricity generation exceed 25pc, according to the IEA report.

In a move to increase the level of wind generation in Ireland, the Government-controlled Ireland Strategic Investment Fund (Isif) teamed up with German solar and wind park operator Capital Stage in January to invest €140m in 20 solar parks in Ireland.

#google#

The parks are being developed by Dublin-based Power Capital, and it marks the first time that Isif has committed to financing solar park developments in this country.

Globally, renewables accounted for almost two-thirds of net new power capacity, with nearly 165 gigawatts (GW) coming online in 2016.

This was a record year that was largely driven by a booming solar market in China and around the world.

In 2016 solar capacity around the world grew by 50pc, reaching over 74 GW, with China's solar PV accounting for almost half of this expansion. In another first, solar energy additions rose faster than any other fuel, surpassing the net growth in coal, the IEA report found.

China alone is responsible for over two-fifths of global renewable capacity growth, which, according to the IEA, is largely driven by concerns about the country's air pollution and capacity targets.

The Asian giant is also the world market leader in hydropower, bioenergy for electricity and heat, and electric vehicles, the IEA report said. In 2016 the United States remained the second largest growth market for renewables.

However, with US President Donald Trump withdrawing the country from the Paris Agreement on climate change, the country's commitment to renewable energy faces policy uncertainty.

Meanwhile, India continues to grow its renewable electricity capacity, and by 2022, the country is expected to more than double its current renewable electricity capacity, according to the IEA. For the first time, this growth over the forecast period (2016-2022) is higher compared with the European Union, according to the report.

Meanwhile in the EU, renewable energy growth over the forecast period is 40pc lower compared with the previous five-year period.

The low forecast in respect of the EU is based on a number of factors, the IEA said, including weaker electricity demand, overcapacity, and limited visibility on forthcoming auction capacity volumes in some markets.

Overall, the Government has committed to generating 40pc of its electricity from renewable energy sources by 2020.

That target is set to be missed, which would see the Government eventually having to fork out hundreds of millions of euro for carbon credits.

Later this year, Ireland will host Europe's biggest summit on Climate Innovation, during which over 50 nationwide events and initiatives will be held.

CrashOverride malware is a Russian-linked ICS cyberweapon targeting power grids, SCADA systems, and utility networks; linked to Electrum/Sandworm, it threatens U.S. transmission and distribution with modular attacks and time-bomb payloads across critical infrastructure.

Key Points

A modular ICS malware linked to Russian actors that disrupts power grids via SCADA abuse and forced breaker outages.

✅ Targets breakers and substation devices to sustain outages

✅ Modular payloads adapt to ICS protocols and vendors

✅ Enables timed, multi-site attacks against transmission and distribution

Hackers allied with the Russian government have devised a cyberweapon that has the potential to be the most disruptive yet against electric systems that Americans depend on for daily life, according to U.S. researchers.

The malware, which researchers have dubbed CrashOverride, is known to have disrupted only one energy system — in Ukraine in December. In that incident, the hackers briefly shut down one-fifth of the electric power generated in Kiev.

But with modifications, it could be deployed against U.S. electric transmission and distribution systems to devastating effect, said Sergio Caltagirone, director of threat intelligence for Dragos, a cybersecurity firm that studied the malware and issued a recent report.

And Russian government hackers have shown their interest in targeting U.S. energy and other utility systems, with reports of suspected breaches at U.S. power plants in recent years, researchers said.

“It’s the culmination of over a decade of theory and attack scenarios,” Caltagirone warned. “It’s a game changer.”

The revelation comes as the U.S. government is investigating a wide-ranging, ambitious effort by the Russian government last year to disrupt the U.S. presidential election and influence its outcome, and has issued a condemnation of Russian power grid hacking as well. That campaign employed a variety of methods, including hacking hundreds of political and other organizations, and leveraging social media, U.S. officials said.

Dragos has named the group that created the new malware Electrum, and it has determined with high confidence that Electrum used the same computer systems as the hackers who attacked the Ukraine electric grid in 2015. That attack, which left 225,000 customers without power, was carried out by Russian government hackers, other U.S. researchers concluded. U.S. government officials have not officially attributed that attack to the Russian government, but some privately say they concur with the private-sector analysis.

“The same Russian group that targeted U.S. [industrial control] systems in 2014, including the Dragonfly campaign documented by Symantec, turned out the lights in Ukraine in 2015,” said John Hultquist, who analyzed both incidents while at iSight Partners, a cyber-intelligence firm now owned by FireEye, where he is director of intelligence analysis. Hultquist’s team had dubbed the group Sandworm.

“We believe that Sandworm is tied in some way to the Russian government — whether they’re contractors or actual government officials, we’re not sure,” he said. “We believe they are linked to the security services.”

Sandworm and Electrum may be the same group or two separate groups working within the same organization, but the forensic evidence shows they are related, said Robert M. Lee, chief executive of Dragos.

The Department of Homeland Security, which works with the owners of the nation’s critical infrastructure systems, did not respond to a request for comment Sunday.

Energy-sector experts said that the new malware is cause for concern, but that the industry is seeking to develop ways to disrupt attackers who breach their systems, including documented access to U.S. utility control rooms in prior incidents.

“U.S. utilities have been enhancing their cybersecurity, but attacker tools like this one pose a very real risk to reliable operation of power systems,” said Michael J. Assante, who worked at Idaho National Labs and is a former chief security officer of the North American Electric Reliability Corporation, where he oversaw the rollout of industry cybersecurity standards.

CrashOverride is only the second instance of malware specifically tailored to disrupt or destroy industrial control systems. Stuxnet, the worm created by the United States and Israel to disrupt Iran’s nuclear capability, was an advanced military-grade weapon designed to affect centrifuges that enrich uranium.

In 2015, the Russians used malware to gain access to the power supply network in western Ukraine, but it was hackers at the keyboards who remotely manipulated the control systems to cause the blackout — not the malware itself, Hultquist said.

With CrashOverride, “what is particularly alarming . . . is that it is all part of a larger framework,” said Dan Gunter, a senior threat hunter for Dragos.

The malware is like a Swiss Army knife, where you flip open the tool you need and where different tools can be added to achieve different effects, Gunter said.

Theoretically, the malware can be modified to attack different types of industrial control systems, such as water and gas. However, the adversary has not demonstrated that level of sophistication, Lee said.

Still, the attackers probably had experts and resources available not only to develop the framework but also to test it, Gunter said. “This speaks to a larger effort often associated with nation-state or highly funded team operations.”

One of the most insidious tools in CrashOverride manipulates the settings on electric power control systems. It scans for critical components that operate circuit breakers and opens the circuit breakers, which stops the flow of electricity. It continues to keep them open even if a grid operator tries to close them, creating a sustained power outage.

The malware also has a “wiper” component that erases the software on the computer system that controls the circuit breakers, forcing the grid operator to revert to manual operations, which means driving to the substation to restore power.

With this malware, the attacker can target multiple locations with a “time bomb” functionality and set the malware to trigger simultaneously, Lee said. That could create outages in different areas at the same time.

The outages would last a few hours and probably not more than a couple of days, Lee said. That is because the U.S. electric industry has trained its operators to handle disruptions caused by large storms, alongside a renewed focus on protecting the grid in response to recent alerts. “They’re used to having to restore power with manual operations,” he said.

So although the malware is “a significant leap forward in tradecraft, it’s also not a doomsday scenario,” he said.

The malware samples were first obtained by ESET, a Slovakian research firm, which shared some of them with Dragos. ESET has dubbed the malware Industroyer.

San Diego Gas & Electric EV incentives deliver $10,000 utility discounts plus a $200 EV Climate Credit, stackable with California rebates and federal tax credits on BMW i3 and Nissan Leaf purchases through participating dealers.

Key Points

Utility-backed rebates that cut EV purchase costs and stack with California and federal tax credits for added savings.

✅ $10,000 off BMW i3 or Nissan Leaf via SDG&E partner dealers

✅ Stack with $7,500 federal and up to $4,500 California rebates

✅ $200 annual EV Climate Credit for eligible account holders

For southern California residents, it's an excellent time to start considering the purchase of a BMW i3 or Nissan Leaf electric car as EV sales top 20% in California today.

San Diego Gas & Electric has joined a host of other utility companies in the state in offering incentives towards the purchase of an i3 or a Leaf as part of broader efforts to pursue EV grid stability initiatives in California.

In total, the incentives slash $10,000 from the purchase price of either electric car, and an annual $200 credit to reduce the buyer's electricity bill is included through the EV Climate Credit program, which can complement home solar and battery options for some households.

SDG&E's incentives may be enough to sway some customers into either electric car, but there's better news: the rebates can be combined with state and federal incentives.

The state of California offers a $4,500 purchase rebate for qualified low-income applicants, while others are eligible for $2,500

Additionally, the federal government income-tax credit of up to $7,500 can bring the additional incentives to $10,000 on top of the utility's $10,000.

While the federal and state incentives are subject to qualifications and paperwork established by the two governments, the utility company's program is much more straight forward.

SDG&E simply asks a customer to provide a copy of their utility bill and a discount flyer to any participating BMW or Nissan dealership.

Additional buyers who live in the same household as the utility's primary account holder are also eligible for the incentives, although proof of residency is required.

Nissan is likely funding some of the generous incentives to clear out remaining first-generation Nissan Leafs.

The 2018 Nissan Leaf will be revealed next month and is expected to offer a choice of two battery packs—one of which should be rated at 200 miles of range or more.

SDG&E joins Southern California Edison as the latest utility company to offer discounts on electric cars as California aims for widespread electrification and will need a much bigger grid to support it, though SCE has offered just $450 towards a purchase.

However, the $450 incentive can be applied to new and used electric cars.

Up north, California utility company Pacific Gas & Electric offers $500 towards the purchase of an electric car as well, and is among utilities plotting a bullish course for EV charging infrastructure across the state today.

Two Hawaiian utilities—Kaua'i Island Utility Cooperative and the Hawaiian Electric Company—offered $10,000 rebates similar to those in San Diego from this past January through March.

Those rebates once again were destined for the Nissan Leaf.

SDG&E's program runs through September 30, 2017, or while supplies of the BMW i3 and Nissan Leaf last at participating local dealers.
