New Rules for a Future Puerto Rico Microgrid Landscape

UK Electricity Price Surge driven by wholesale gas costs, low wind output, and higher gas-fired generation, as National Grid boosts base load power to meet demand, lifting weekend prices toward decade highs.

Key Points

A sharp rise in UK power prices tied to gas spikes, waning wind, and higher reliance on gas-fired generation.

✅ Wholesale gas prices squeeze power, doubling weekend baseload.

✅ Wind generation falls to 3GW, forcing more gas-fired plants.

✅ Tariff hikes signal bill pressure and supplier strain.

The UK’s electricity market has followed the lead of surging wholesale gas prices this week to reach weekend highs, with UK peak power prices not seen in a decade across the market.

The power market has avoided the severe volatility which ripped through the gas market this week because strong winds helped to supply ample electricity to meet demand, reflecting recent record wind generation across the UK.

But as freezing winds begin to wane this weekend National Grid will need to use more gas-fired power plants to fill the gap, meaning the cost of generating electricity will surge.

Jamie Stewart, an energy expert at ICIS, said the price for base load power this weekend has already soared to around £80 per megawatt hour, almost double what one would expect to see for a weekend in March.

National Grid will increase its use of expensive gas-fired power by an extra 7GW to make up for low wind power, which is forecast to drop by two-thirds in the days ahead.

Wind speeds helped to protect the electricity system from huge price hikes on the neighbouring gas market on Thursday, by generating as much as 13GW by some estimates.

However, by the end of Friday this output will fall by almost half to 7GW and slump to lows of 3GW by Saturday, Mr Stewart said.

The power price was already higher than usual at £53/MWh last weekend even before the full force of the storms, including Storm Malik wind generation, hit Britain. That was still well above the more typical "mid-40s” price for this time of year, Mr Stewart added.

The twin price spikes across the UK’s energy markets has raised fears of household bill hikes in the months ahead, even as an emergency energy plan is not going ahead.

Late on Thursday Big Six supplier E.on quietly pushed through a dual-fuel tariff increase of 2.6%, to drive the average bill up to £1,153 from 19 April.

Energy supply minnow Bulb also increased prices by £24 a year for its 300,000 customers, blaming rising wholesale costs.

The UK has suffered two gas price shocks this winter, which is the first since the owner of British Gas shuttered the country’s largest gas storage facility at Rough off the Yorkshire coast.

A string of gas supply outages this week cut supplies to the UK just as freezing conditions drove demand for gas-heating a third higher than normal for this time of year.

It was the first time in almost ten years that National Grid was forced to issue a short supply warning to the market that supplies would fall short of demand unless factories agree to use less.

The twelve-year market price highs followed a pre-Christmas spike when the UK’s most important North Sea pipeline shut down at the same time as a deadly explosion at Europe’s most important gas hub, based in the Austrian town of Baumgarten.

Russian cyberattacks on U.S. power grid exposed DHS warnings: Dragonfly/Energetic Bear breached control rooms, ICS networks, and could trigger blackouts via switch manipulation, phishing, and malware, threatening critical infrastructure and utility operations nationwide.

Key Points

State-backed breaches of utility ICS and control rooms enabled potential switch manipulation and blackouts.

✅ DHS: Dragonfly/Energetic Bear breached utility networks

✅ Access reached control rooms and ICS for switch control

✅ Ongoing campaign via phishing, malware, lateral movement

Russian hackers for a state-sponsored organization invaded hundreds of control rooms of U.S. electric utilities that could have led to blackouts, a new report says.

The group, known as Dragonfly or Energetic Bear, infiltrated networks of U.S. utilities as part of an effort that is likely ongoing, Department of Homeland Security officials told the Wall Street Journal.

Jonathan Home, chief of industrial-control-system analysis for DHS, said the hackers “got to the point where they could have thrown switches” and upset power flows.

Although the agency did not disclose which companies were impacted, the officials at a briefing Monday said that there were “hundreds of victims” including breaches at power plants across the U.S., and that some companies may not be aware that hackers infiltrated their networks yet.

According to experts, Russia has been preparing for such attacks for some time now, prompting a renewed focus on protecting the grid among utilities and policymakers.

“They’ve been intruding into our networks and are positioning themselves for a limited or widespread attack,” said former Deputy Assistant Defense Secretary Michael Carpenter, now senior director at the Penn Biden Center at the University of Pennsylvania, per the Wall Street Journal. “They are waging a covert war on the West.”

Earlier this year, the Trump administration claimed Russia had staged a power grid hacking campaign against the U.S. energy grid and other U.S. infrastructure.

The report comes after President Trump told reporters last week during a joint press conference in Helsinki alongside Russian President Vladimir Putin that he had no reason not to believe the Russian leader's assurances to him that the Kremlin was not to blame for interference in the election.

Trump later admitted that he misspoke when he said he didn’t “see any reason why” Russia would have meddled in the 2016 election, and said he believes the U.S. intelligence community assessment that found that the Russian government did interfere in the electoral process.

Cooperative Energy bond rating upgrade signals lower debt costs as Fitch lifts GO Zone Bonds to A, reflecting Kemper exit, shift to owned generation, natural gas, and renewable energy for co-op members and borrowing rates.

Key Points

Fitch raised Cooperative Energy's GO Zone Bonds to A, cutting debt costs after Kemper exit and shift to natural gas.

✅ Fitch upgrades 2009A GO Zone Bonds from A- to A.

✅ Kemper divestment reduced risk and exposure to coal.

✅ Shift to owned generation, natural gas, renewables lowers costs.

Cooperative Energy and its 11 co-op members will see lower debt costs on $35.4 million bond; similar to regional utilities offering one-time bill decreases for customers recently.

Bailing out of its 15 percent ownership stake in Mississippi Power’s Kemper gasification plant, amid debates over coal and nuclear subsidies in federal policy, has helped Hattiesburg-based Cooperative Energy gain a ratings upgrade on a $35.4 million bond issue.

The electric power co-op, which changed its name to Cooperative Energy from South Mississippi Electric Power Association in November, received a ratings upgrade from A- to A for its 2009 2009A Mississippi Business Finance Corporation Gulf Opportunity Zone Bonds, even as other utilities announced bill reductions for customers during 2020.

“This rating upgrade reflects the success of our strategy to move from purchased power to owned generation resources, and from coal to natural gas and renewable energy as clean energy priorities gain traction,” said Cooperative Energy President/CEO Jim Compton in a press release.  “The result for our members is lower borrowing costs and more favorable rates.”

An “A” rating from Fitch designates the bond issue as “near premium quality,” a status noted as utilities adapted to pandemic-era electricity demand trends nationwide.

A high-level delegation from Dubai Electricity and Water Authority (Dewa) recently visited China in bid to build closer ties with Chinese renewable and clean energy and smart services and smart grid companies, amid broader power grid modernization in Asia trends.

The team led by the managing director and CEO Saeed Mohammed Al Tayer visited the headquarters of Hanergy Holding Group, one of the largest international companies in alternative and renewable energy, in Beijing.

The visit complements the co-operation between Dewa and Hanergy after the signing MoU between the two sides last May, said a statement from Dewa.

The two parties focused on renewable and clean energy and its development, including efforts to integrate solar into the grid through advanced programs, and enhancing opportunities for joint investment.

Al Tayer also visited the Exhibition Hall and Exhibition Centre of the Hanergy Clean Energy Exhibition spread over a 7,000-sq-m area at the Beijing Olympic Park.

He discussed solar power technologies and applications, which included integrated photovoltaic panels and their distribution on the roofs of industrial and residential buildings, residential and mobile power systems, micro-grid installations in remote regions, solar-powered vehicles, and various elements of the exhibition.

Al Tayer and the accompanying delegation later visited the Beijing R&D Centre, which is one of Huaweis largest research institutes, known for Huawei smart grid initiatives across global markets, that employs over 12,000 people. The centre covers the latest pre-5G solutions, Cloud, Big Data, as well as vertical solutions for a smart and safe city.

"The visit is part of a joint venture with Huawei, which includes R&D projects to develop smart network infrastructures and various mechanisms and technologies, aligned with recent U.S. grid improvement funding initiatives, such as smart meters for electricity and water services, energy demand management, and self-recovery mechanisms from errors and disasters," he added.

U.S. Power Grid Cybersecurity combats DHS-FBI flagged threats to energy infrastructure, with PJM Interconnection using ICS/SCADA segmentation, phishing defenses, incident response, and resilience exercises against Russia-linked attacks and pipeline intrusions.

Key Points

Strategies, controls, and training that protect U.S. electric infrastructure from cyber threats and disruptions.

✅ ICS/SCADA network segmentation and zero-trust architecture

✅ Employee phishing drills and incident response playbooks

✅ DOE-led grid exercises and threat intelligence sharing

The joint alert from the FBI and Department of Homeland Security last month warning that Russia was hacking into critical U.S. energy infrastructure, as outlined in six essential reads on Russian hacks from recent coverage, came as no surprise to the nation’s largest grid operator, PJM Interconnection.

“You will never stop people from trying to get into your systems. That isn’t even something we try to do.” said PJM Chief Information Officer, Tom O’Brien. “People will always try to get into your systems. The question is, what controls do you have to not allow them to penetrate? And how do you respond in the event they actually do get into your system?”

PJM is the regional transmission organization for 65 million people, covering 13 states, including Pennsylvania, and Washington D.C.

On a rainy day in early April, about 10 people were working inside PJM’s main control center, outside Philadelphia, closely monitoring floor-to-ceiling digital displays showing real-time information from the electric power sector throughout PJM’s territory in the mid-Atlantic and parts of the midwest, amid reports that hackers accessed control rooms at U.S. utilities.

Donnie Bielak, a reliability engineering manager, was overseeing things from his office, perched one floor up.

“This is a very large, orchestrated effort that goes unnoticed most of the time,” Bielak said. “That’s a good thing.”

But the industry certainly did take notice in late 2015 and early 2016, when hackers successfully disrupted power to the Ukrainian grid. The outages lasted a few hours and affected about 225,000 customers. It was the first publicly-known case of a cyber attack causing major disruptions to a power grid. It was widely blamed on Russia.

One of the many lessons of the Ukraine attacks was a reminder to people who work on critical infrastructure to keep an eye out for odd communications.

“A very large percentage of entry points to attacks are coming through emails,” O’Brien said. “That’s why PJM, as well as many others, have aggressive phishing campaigns. We’re training our employees.”

O’Brien doesn’t want to get into specifics about how PJM deals with cyber threats. But one common way to limit exposure is by having separate systems: For example, industrial controls in a power plant are not connected to corporate business networks, a separation underscored after breaches at U.S. power plants prompted reviews across the sector.

Since 2011, North American grid operators and government agencies have also done large, security exercises every two years. Thousands of people practice how they’d respond to a coordinated physical or cyber event, including rising substation attacks that highlight resilience gaps.

So far, nothing like that has happened in the U.S. It’s possible, but not likely, according to Robert M. Lee, a former military intelligence analyst, who runs the industrial cybersecurity firm Dragos.

“The more complex the system, the harder it is to have a scalable attack,” said Lee, who co-authored a report analyzing the Ukraine attacks. “If you wanted to take out a power generation station– that isn’t the most complex thing. Let’s say you cause an hour of outage. But now you want to cause two months of outages? That’s an exponential increase in effort required.”

For example, he said, it would very difficult for hackers to knock out power to the entire east coast for a long time. But briefly disrupting a major city is easier. That’s the sort of thing that keeps him up at night.

“I worry about an adversary getting into, maybe, Washington D.C.’s portion of the grid, taking down power for 30 minutes,” he said.

The Department of Energy is creating a new office focused on cybersecurity and emergency response, following the U.S. government’s condemnation of power grid hacking by Russia.

Deterrence may be one reason why there has not yet been a major attack on the U.S. grid, said John MacWilliams, a former senior DOE official who’s now a fellow at Columbia University’s Center on Global Energy Policy.

“That’s obviously an act of war,” he said. “We have the capability of responding either through cyber mechanisms or kinetic military.”

In the meantime, small-scale incidents keep happening.

This spring, another cyber attack targeted natural gas pipelines. Four companies shut down their computer systems, just in case, but they say no service was disrupted.

Georgia Electricity Imports October 2017 surged as hydropower output fell and thermal power plants underperformed; ESCO balanced demand via low-cost imports, mainly from Azerbaijan, amid rising tariffs, kWh consumption growth, and a widening generation-consumption gap.

Key Points

They mark a record import surge due to costly local generation, lower hydropower, ESCO balancing costs, and rising demand.

✅ Imports rose 832% YoY to 157 mln kWh, mainly from Azerbaijan

✅ TPP output fell despite capacity; only low-tariff plants ran

✅ Balancing price 13.8 tetri/kWh signaled costly domestic PPAs

In October 2017, Georgian power plants generated 828 mln. KWh of electricity, marginally up (+0.79%) compared to September. Following the traditional seasonal pattern and amid European concerns over dispatchable power shortages affecting markets, the share of electricity produced by renewable sources declined to 71% of total generation (87% in September), while thermal power generation’s share increased, accounting for 29% of total generation (compared to 13% in September). When we compare last October’s total generation with the total generation of October 2016, however, we observe an 8.7% decrease in total generation (in October 2016, total generation was 907 mln. kWh). The overall decline in generation with respect to the previous year is due to a simultaneous decline in both thermal power and hydro power generation. 

Consumption of electricity on the local market in the same period was 949 mln. kWh (+7% compared to October 2016, and +3% with respect to September 2017), and reflected global trends such as India's electricity growth in recent years. The gap between consumption and generation increased to 121 mln. kWh (15% of the amount generated in October), up from 100 mln. kWh in September. Even more importantly, the situation was radically different with respect to the prior year, when generation exceeded consumption.

The import figure for October was by far the highest from the last 12 years (since ESCO was established), occurring as Ukraine electricity exports resumed regionally, highlighting wider cross-border dynamics. In October 2017, Georgia imported 157 mln. kWh of electricity (for 5.2 ¢/kWh – 13 tetri/kWh). This constituted an 832% increase compared to October 2016, and is about 50% larger than the second largest import figure (104.2 mln. kWh in October 2014). Most of the October 2017 imports (99.6%) came from Azerbaijan, with the remaining 0.04% coming from Russia.

The main question that comes to mind when observing these statistics is: why did Georgia import so much? One might argue that this is just the result of a bad year for hydropower generation and increased demand. This argument, however, is not fully convincing. While it is true that hydropower generation declined and demand increased, the country’s excess demand could have been easily satisfied by its existing thermal power plants, even as imported coal volumes rose in regional markets. Instead of increasing, however, the electricity coming from thermal power plants declined as well. Therefore, that cannot be the reason, and another must be found. The first that comes to mind is that importing electricity may have been cheaper than buying it from local TPPs, or from other generators selling electricity to ESCO under power purchase agreements (PPAs). We can test the first part of this hypothesis by comparing the average price of imported electricity to the price ceiling on the tariff that TPPs can charge for the electricity they sell. Looking at the trade statistics from Geostat, the average price for imported electricity in October 2017 remained stable with respect to the same month of the previous year, at 5.2 ¢ (13 tetri) per kWh. Only two thermal power plants (Gardabani and Mtkvari) had a price ceiling below 13 tetri per kWh. Observing the electricity balance of Georgia, we see that indeed more than 98% of the electricity generated by TPPs in October 2017 was generated by those two power plants.

What about other potential sources of electricity amid Central Asia's power shortages at the time? To answer this question, we can use the information derived from the weighted average price of balancing electricity. Why balancing electricity? Because it allows us to reconstruct the costs the market operator (ESCO) faced during the month of October to make sure demand and supply were balanced, and it allows us to gain an insight about the price of electricity sold through PPAs.

ESCO reports that the weighted average price of balancing electricity in October 2017 was 13.8 tetri/kWh, (25% higher than in October 2016, when it was below the average weighted cost of imports – 11 vs. 13 – and when the quantity of imported electricity was substantially smaller). Knowing that in October 2017, 61% of balancing electricity came from imports, while 39% came from hydropower and wind power plants selling electricity to ESCO under their PPAs, we can deduce that in this case, internal generation was (on average) also substantially more expensive than imports. Therefore, the high cost of internally generated electricity, rather than the technical impossibility of generating enough electricity to satisfy electricity demand, indeed appears to be one the main reasons why electricity imports spiked in October 2017.
