South Africa's power outages attract independent solutions

DARPA RADICS Power Grid Security targets DoD resilience to cyber attacks, delivering early warning, detection, isolation, and characterization tools, plus a secure emergency network to protect critical infrastructure and speed grid restoration and communications.

Key Points

A DoD/DARPA initiative to detect, contain, and rapidly recover the U.S. grid from sophisticated cyber attacks.

✅ Early warning separates attacks from routine outages

✅ Pinpoints intrusion points and malware used

✅ Builds secure emergency network for rapid restoration

The U.S. Department of Defense is growing increasingly concerned about hackers taking down our power grid and crippling the nation, reflecting a renewed focus on grid protection across agencies, which is why the Pentagon has created a $77-million security plan that it hopes will be up and running by 2020.

The U.S. power grid is threatened every few days. While these physical and cyber attacks have never led to wide-scale outages, attacks are getting more sophisticated. According to a 494-page report released by the Department of Energy in January and a new grid report card, the nation’s grid “faces imminent danger from cyber attacks.” Such a major, sweeping attack could threaten “U.S. lifeline networks, critical defense infrastructure, and much of the economy; it could also endanger the health and safety of millions of citizens.” If it were to happen today, America could be powered-down and vulnerable for weeks.

The DoD is working on an automated system to speed up recovery time to a week or less — what it calls the Rapid Attack Detection, Isolation, and Characterization (RADICS) program. DARPA, the Pentagon’s research arm, originally solicited proposals in late 2015, asking for technology that did three things. Primarily, it had to detect early warning signs and distinguish between attacks and normal outages, especially after intrusions at U.S. electric utilities underscored the risk, but it also had to pinpoint the access point of the attack and determine what malicious software was used. Finally, it must include an emergency system that can rapidly connect various power-supply centers, without any human coordination. This would allow emergency and military responders to have an ad hoc communication system in place moments after an attack.

“If a well-coordinated cyberattack on the nation’s power grid were to occur today, the time it would take to restore power would pose daunting national security challenges,” said DARPA program manager John Everett, in a statement, at the time. “Beyond the severe domestic impacts, including economic and human costs, prolonged disruption of the grid would hamper military mobilization and logistics, impairing the government’s ability to project force or pursue solutions to international crises.”

DARPA plans to spend $77 million on RADICS, while DOE funding to improve the grid complements these initiatives. Last November, SRI International announced it had received $7.3 million from the program. In December, Raython was granted $9 million. The latest addition is BAE Systems, which received $8.6 million last month to develop technology that detects and contains power-grid threats, and creates a secure emergency provisional system that restores some power and communication in the wake of an attack — what is being called a secure emergency network.

According to the military news site Defense Systems, BAE’s SEN would rely on radio, satellite, or wireless internet — particularly as ransomware attacks continue to rise — whatever is available that allows the grid to continue working. The SEN would serve as a wireless connection between separate power grid stations.

While the ultimate goal of the RADICS program will be the restoration of civilian power and communications, the SEN will prioritize communication networks that would be used for defense or combat, so the U.S. government can still wage war while the rest of us are in the dark.

2022 US Renewable Power Milestone highlights EIA data: wind and solar outpaced coal and nuclear, hydropower contributed, with falling levelized costs, grid integration, battery storage, and transmission upgrades shaping affordable, reliable clean power growth.

Key Points

The year US renewables, led by wind and solar, generated more power than coal and nuclear, per EIA.

✅ Wind and solar rose; levelized costs fell 70%-90% over decade

✅ Renewables surpassed coal and nuclear in 2022 per EIA

✅ Grid needs storage and transmission to manage intermittency

Electricity generated from renewables surpassed coal in the United States for the first time in 2022, as wind and solar surpassed coal nationwide, the U.S. Energy Information Administration has announced.

Renewables also surpassed nuclear generation in 2022 after first doing so last year, and wind and solar together generated more electricity than nuclear for the first time in the United States.

Growth in wind and solar significantly drove the increase in renewable energy and contributed 14% of the electricity produced domestically in 2022, with solar producing about 4.7% of U.S. power overall. Hydropower contributed 6%, and biomass and geothermal sources generated less than 1%.

“I’m happy to see we’ve crossed that threshold, but that is only a step in what has to be a very rapid and much cheaper journey,” said Stephen Porder, a professor of ecology and assistant provost for sustainability at Brown University.

California produced 26% of the national utility-scale solar electricity followed by Texas with 16% and North Carolina with 8%.

The most wind generation occurred in Texas, which accounted for 26% of the U.S. total, while wind is now the most-used renewable electricity source nationwide, followed by Iowa (10%) and Oklahoma (9%).

“This booming growth is driven largely by economics,” said Gregory Wetstone, president and CEO of the American Council on Renewable Energy, as renewables became the second-most prevalent U.S. electricity source in 2020 nationwide. “Over the past decade, the levelized cost of wind energy declined by 70 percent, while the levelized cost of solar power has declined by an even more impressive 90 percent.”

“Renewable energy is now the most affordable source of new electricity in much of the country,” added Wetstone.

The Energy Information Administration projected that the wind share of the U.S. electricity generation mix will increase from 11% to 12% from 2022 to 2023 and that solar will grow from 4% to 5% during the period, and renewables hit a record 28% share in April according to recent data. The natural gas share is expected to remain at 39% from 2022 to 2023, and coal is projected to decline from 20% last year to 17% this year.

“Wind and solar are going to be the backbone of the growth in renewables, but whether or not they can provide 100% of the U.S. electricity without backup is something that engineers are debating,” said Brown University’s Porder.

Many decisions lie ahead, he said, as the proportion of renewables that supply the energy grid increases, with renewables projected to soon be one-fourth of U.S. electricity generation over the near term.

This presents challenges for engineers and policy-makers, Porder said, because existing energy grids were built to deliver power from a consistent source. Renewables such as solar and wind generate power intermittently. So battery storage, long-distance transmission and other steps will be needed to help address these challenges, he said.

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 Solar Energy Contracts secure low-cost photovoltaic PPAs for government operations, delivering renewable electricity at 4.8 cents/kWh, beating natural gas LCOE, enhancing summer grid efficiency across Hays, Tilley, and Jenner with Canadian Solar.

Key Points

Low-cost PV power agreements meeting 55% of Alberta government electricity demand via new Canadian Solar facilities.

✅ Price: 4.8 cents/kWh CAD, under gas-fired generation LCOE.

✅ Sites: Hays, Tilley, Jenner; 50% equity with Conklin Métis Local #193.

✅ Supplies 55% of provincial government electricity demand.

Three new solar electricity facilities to be built in south eastern Alberta (Canada) amid Alberta's solar growth have been selected through a competitive process to supply the Government of Alberta with 55 per cent of their annual electricity needs. The facilities will be built near Hays, Tilley, and Jenner, by Canadian Solar with Conklin Métis Local #193 as 50-percent equity owners.

The Government of Alberta's operations have been powered 100 per cent with wind power since 2007. Upon the expiration of some of these contracts, they have been renewed to switch from wind to solar energy. The average contract pricing will be $0.048 per kilowatt hour (3.6 cents/kWh USD), which is less than the average historical wholesale power pool price paid to natural gas-fired electricity in the province in years 2008 - 2018.

"The conversation about solar energy has long been fixated on its price competitiveness with fossil fuels," said John Gorman, CanSIA President & CEO. "Today's announcement demonstrates that low cost solar energy has arrived as a mainstream option in Alberta, even as demand for solar lags in Canada according to federal assessments. The conversation should next focus on how to optimize an all-of-the-above strategy for developing the province's renewable and non-renewable resources."

"This price discovery is monumental for the solar industry in Canada" said Patrick Bateman, CanSIA Director of Policy & Market Development. "At less than five cents per kilowatt hour, this solar electricity has a cost that is less than that of natural gas. Achieving Alberta's legislated 30 per cent by 2030 renewable electricity target just became a whole lot cheaper!".

Quick Facts:

• The contract price of 4.8 cents/kWh CAD to be paid by Alberta Infrastructure for this solar electricity represents a lower Levelized Cost of Electricity (LCOE) than the average annual wholesale price paid by the power pool to combined-cycle and single-cycle natural gas-fired electricity generation which was 7.1 cents/kWh and 11.2 cents/kWh respectively from 2008 - 2018.

• Alberta receives more hours of sunshine than Miami, Florida in the summer months. Alberta's electricity supply is most strained in summer, highlighting challenges for solar expansion when high temperatures increase the resistance of the distribution and transmission systems, and reduce the efficiency of cooling thermal power plants. For this reason, solar facilities sited near to electricity demand improves overall grid efficiency. Supply shortages are atypical in Alberta in winter when solar energy is least available. When they do occur, imports are increased and large loads are decreased.

• In 2018, Alberta's solar electricity generation exceeded 50 MW. While representing much less than 1% of the province's electricity supply today, the Canadian Solar Industries Association (CanSIA) forecasts that solar energy could supply as much as 3 per cent of the province's electricity by 2030, supporting renewable energy job growth across Alberta. A recent supply chain study of the solar electricity sector in Alberta by Solas Energy Consulting Inc. found a potential of $4.1 billion in market value and a labour force rising to 10,000 in 2030.

Hinkley Point C delays highlight EDF cost overruns, energy security risks, and wholesale power prices, complicating UK net zero plans, Sizewell C financing, and small modular reactor adoption across the grid.

Key Points

Delays at EDF's 3.2GW Hinkley Point C push operations to 2031, lift costs to £46bn, and risk pricier UK electricity.

✅ First unit may slip to 2031; second unit date unclear.

✅ LSEG sees 6% wholesale price impact in 2029-2032.

✅ Sizewell C replicates design; SMR contracts expected soon.

Vincent de Rivaz, former CEO of EDF, confidently announced in 2016 the commencement of the UK's first nuclear power station since the 1990s, Hinkley Point C. However, despite milestones such as the reactor roof installation, recent developments have belied this optimism. The French state-owned utility EDF recently disclosed further delays and cost overruns for the 3.2 gigawatt plant in Somerset.

These complications at Hinkley Point C, which is expected to power 6 million homes, have sparked new concerns about the UK's energy strategy and its ambition to decarbonize the grid by 2050.

The UK government's plan to achieve net zero by 2050 includes a significant role for nuclear energy, reflecting analyses that net-zero may not be possible without nuclear and aiming to increase capacity from the current 5.88GW to 24GW by mid-century.

Simon Virley, head of energy at KPMG in the UK, stressed the importance of nuclear energy in transitioning to a net zero power system, echoing industry calls for multiple new stations to meet climate goals. He pointed out that failing to build the necessary capacity could lead to increased reliance on gas.

Hinkley Point C is envisioned as the pioneer in a new wave of nuclear plants intended to augment and replace Britain's existing nuclear fleet, jointly managed by EDF and Centrica. Nuclear power contributed about 14 percent of the UK's electricity in 2022, even as Europe is losing nuclear power across the continent. However, with the planned closure of four out of five plants by March 2028 and rising electricity demand, there is concern about potential power price increases.

Rob Gross, director of the UK Energy Research Centre, emphasized the link between energy security and affordability, highlighting the risk of high electricity prices if reliance on expensive gas increases.

The first 1.6GW reactor at Hinkley Point C, initially set for operation in 2027, may now face delays until 2031, even after first reactor installation milestones were reported. The in-service date for the second unit remains uncertain, with project costs possibly reaching £46bn.

LSEG analysts predict that these delays could increase wholesale power prices by up to 6 percent between 2029 and 2032, assuming the second unit becomes operational in 2033.

Martin Young, an analyst at Investec, warned of the price implications of removing a large power station from the supply side.

In response to these delays, EDF is exploring the extension of its four oldest plants. Jerry Haller, EDF’s former decommissioning director, had previously expressed skepticism about extending the life of the advanced gas-cooled reactor fleet, but EDF has since indicated more positive inspection results. The company had already decided to keep the Heysham 1 and Hartlepool plants operational until at least 2026.

Nevertheless, the issues at Hinkley Point C raise doubts about the UK's ability to meet its 2050 nuclear build target of 24GW.

Previous delays at Hinkley were attributed to the COVID-19 pandemic, but EDF now cites engineering problems, similar to those experienced at other European power stations using the same technology.

The next major UK nuclear project, Sizewell C in Suffolk, will replicate Hinkley Point C's design, aligning with the UK's green industrial revolution agenda. EDF and the UK government are currently seeking external investment for the £20bn project.

Compared with Hinkley Point C, Sizewell C's financing model involves exposing billpayers to some risk of cost overruns. This, coupled with EDF's track record, could affect investor confidence.

Additionally, the UK government is supporting the development of small modular reactors, while China's nuclear program continues on a steady track, with contracts expected to be awarded later this year.
