Sunrise Technologies is teaming with Ember to turn the countryÂ’s grid of streetlights into a wide-area communications network for a host of new public utility, security, environmental and other applications.

Sunrise TechnologiesÂ’ new BrownBetty system creates a mesh network for communications between ground-based sensor and control devices and the Internet, utilizing EmberÂ’s ZigBee wireless network technology. By taking advantage of the existing streetlight infrastructure with its high elevation poles and clean line of sight, BrownBetty dramatically lowers the cost of backhaul communications while enabling applications that were previously not practical or affordable.

For utilities, these could include automatic meter reading (AMR), time-of-use metering (TOU), advanced metering infrastructure (AMI), remote water meter reading, remote electric meter disconnect, fault indication, distribution automation, and utility GPS mapping.

Other applications include Homeland Security sensor monitoring, peak period load shedding (air conditioners, water heaters, pool pumps, etc.), vehicle tracking, bridge stress monitoring, advanced parking meters (APM), storm drain blockage monitoring, water flow monitoring, home/business heating oil tank monitoring, and bridge stress monitoring, among many others.

The system gets its curious name from Brown Betty, the horse used by Paul Revere in his famous ride to alert the Minuteman in Lexington and Concord of the British ArmyÂ’s approach.

“BrownBetty makes smart use of ZigBee to eliminate the need for expensive long haul communications options like cellular, pagers or powerline,” said Bob Gohn, Ember’s Vice President of Marketing. “Because it uses standard based communications, BrownBetty can network work with any other ZigBee enabled devices to form a reliable and robust network.”

Inexpensive communication nodes are plugged into a streetlightÂ’s standard NEMA twist lock receptacles, replacing the lightÂ’s dusk to dawn photocontrols. Thanks to ZigBeeÂ’s self-forming network capabilities, the nodes automatically install themselves into the BrownBetty network, resulting in minimal installation costs. This local network communicates with a network computer operating center through bridge nodes which connect to the internet via fiber, broadband or WiFi connections. A single low cost node can communicate with multiple houses with multiple applications. Each node incorporates a photo control circuit to provide normal dusk to dawn lighting control of the streetlight.

Sunrise Technologies partnered with muNet, a provider of IP and ZigBee-based electric meter interfaces, in a successful pilot of the BrownBetty system at the Taunton Municipal Light Plant (TMLP) in Taunton, Mass. “The system is great because you can start inexpensively on a small scale and expand coverage and add on additional applications when you want them. It makes so many things more efficient,” said Mike Horrigan, General Manager for TMLP. Other participants in the project included NightHawk to perform remote electric meter disconnect/reconnect, DataMatic remote water meter reading, Graphic Technologies, Inc. (GTI) to provide geospatial data, and Power Delivery Products, Inc. for its faulted circuit indicators.

Vance Spillman, Vice President and General Manager of Sunrise Technologies said, “BrownBetty was created to fill the void of cost effective wide area coverage for backhaul of ZigBee device information to the Internet,” he said. “Smart grid implementation becomes instantly affordable. Adding the BrownBetty communications layer to Municipal WiFi systems makes the WiFi technology more useful. It adds value to the WiFi network and makes the WiFi network much more financially viable.”

The BrownBetty system used Ember’s EM250 ZigBee “system-on-chip” transceiver and EmberZNet PRO wireless mesh networking software. Sunrise Technologies realizes that Ember’s ZigBee technology addresses the need for a cost-effective, standards-based wireless networking solution that supports low data-rates, low-power consumption, security and reliability.

Nunavut's electricity price hike explained

Nunavut electricity rate increase sees QEC raise domestic electricity rates 6.6% over two years, affecting customer rates, base rates, subsidies, and kWh overage charges across communities, with public housing exempt and territory-wide pricing denied.

 

Key Points

A 6.6% QEC hike over 2018-2019, affecting customer rates, subsidies, and kWh overage; public housing remains exempt.

✅ 3.3% on May 1, 2018; 3.3% on Apr 1, 2019

✅ Subsidy caps: 1,000 kWh Oct-Mar; 700 kWh Apr-Sep

✅ Territory-wide base rate denied; public housing exempt

 

Ahead of the Nunavut government's approval of the general rate increase for the Qulliq Energy Corporation, many Nunavummiut wondered how the change would impact their electricity bills.

QEC's request for a 6.6-per-cent increase was approved by the government last week. The increase will be spread out over two years, a pattern similar to BC Hydro's two-year rate plan, with the first increase (3.3 per cent) effective May 1, 2018. The remaining 3.3 per cent will be applied on April 1, 2019.

Public housing units, however, are exempt from the government's increase altogether.

The power corporation also asked for a territory-wide rate, so every community would pay the same base rate (we'll go over specific terms in a minute if you're not familiar with them). But that request was denied, even as Manitoba Hydro scaled back increases next year, and QEC will now take the next two years reassessing each community's base rate.

#google#

So, what does this mean for your home's power bill? Well, there's a few things you need to know, which we'll get to in a second.

But in essence, as long as you don't go over the government-subsidized monthly electricity usage limit, you're paying an extra 3.61 cents per kilowatt hour (kWh).

To be clear, we're talking about non-government domestic rates — basically, private homeowners — and those living in a government-owned unit but pay for their own power.

 

The basics

First, some quick terminology. The "base rate" term we're going to use (and used above) in this story refers to the community rate. As in, what QEC charges customers in every community. The "customer rate" is the rate customers actually pay, after the government's subsidy.

 

The first thing you need to know is everyone in Nunavut starts off by paying the same customer rate, unlike jurisdictions using a price cap to limit spikes.

That's because the government subsidizes electricity costs, and that subsidy is different in every community, because the base rate is different.

For example, Iqaluit's new base rate after the 3.3 per cent increase (remember, the 6.6 per cent is being applied over two years) is 56.69 cents per kWh, while Kugaaruk's base rate rose to 112.34 cents per kWh. Those, by the way, are the territory's lowest and highest respective base rates.

However, customers in both Iqaluit and Kugaaruk will each now pay 28.35 cents per kWh because, remember, the government subsidizes the base rates in every community.

Now, remember earlier we mentioned a "government-subsidized monthly electricity usage limit?" That's where customers in various communities start to pay different amounts.

As simply as we can explain it, the government will only cover so much electricity usage in a month, in every household.

Between October and March, the government will subsidize the first 1,000 kilowatt hours, and only 700 kilowatt hours from April to September. QEC says the average Nunavut home will use about 500 kilowatt hours every month over the course of a year.

But if your household goes over that limit, you're at the mercy of your community's base rate for any extra electricity you use. Homes in Kugaaruk in December, for instance, will have to pay that 122.34 cents for every extra kilowatt hour it uses, while homes in Iqaluit only have to pay 56.69 cents per kWh for its extra electricity.

That's where many Nunavummiut have criticized the current rate structure, because smaller communities are paying more for their extra costs than larger communities.

QEC had hoped — as it had asked for — to change the structure so every community pays the same base rate. So regardless of if people go over their electricity usage limits for the government subsidy, everyone would pay the same overage rates.

But the government denied that request.

 

New rate is actually lower

The one thing we should highlight, however, is the new rate after the increase is actually lower than what customers were paying in 2014.

For the past seven months, customers have been getting power from QEC at a discount, whereas Newfoundland customers began paying for Muskrat Falls during the same period, to different effect.

That's because when QEC sets its rates, it does so based on global oil price forecasts. Since 2014, the price of oil worldwide has slumped, and so QEC was able to purchase it at less than it had anticipated.

When that happens, and QEC makes more than $1 million within a six month period thanks to the lower oil prices, it refunds the excess profits back to customers through a discount on electricity base rates — a mechanism similar to a lump-sum credit used elsewhere — the government subsidy, however, doesn't change so the savings are passed on directly to customers.

Now, the 6.6 per cent increase to electricity rates, is actually being applied to the discounted base rate from the last seven months.

So again, while customers are paying more than they have been for the last seven months, it's lower than what they were paying in 2014.

Lastly, to be clear, all the figures used in this story are only for domestic non-government rates. Commercial rates and changes have not been explored in this story, given the differences in subsidy and rate application.

Group of premiers band together to develop nuclear reactor technology

Small Modular Reactors in Canada are advancing through provincial collaboration, offering nuclear energy, clean power and carbon reductions for grids, remote communities, and mines, with factory-built modules, regulatory roadmaps, and pre-licensing by the nuclear regulator.

 

Key Points

Compact, factory-built nuclear units for clean power, cutting carbon for grids, remote communities, and industry.

✅ Provinces: Ontario, Saskatchewan, New Brunswick collaborate

✅ Targets coal replacement, carbon cuts, clean baseload power

✅ Modular, factory-made units; 5-10 year deployment horizon

 

The premiers of Ontario, Saskatchewan and New Brunswick have committed to collaborate on developing nuclear reactor technology in Canada. 

Doug Ford, Scott Moe and Blaine Higgs made the announcement and signed a memorandum of understanding on Sunday in advance of a meeting of all the premiers. 

They will be working on the research, development and building of small modular reactors as a way to help their individual provinces reduce carbon emissions and move away from non-renewable energy sources like coal. 

Small modular reactors are easy to construct, are safer than large reactors and are regarded as cleaner energy than coal, the premiers say. They can be small enough to fit in a school gym. 

SMRs are actually not very close to entering operation in Canada, though Ontario broke ground on its first SMR at Darlington recently, signaling early progress. Natural Resources Canada released an "SMR roadmap" last year, with a series of recommendations about regulation readiness and waste management for SMRs.

In Canada, about a dozen companies are currently in pre-licensing with the Canadian Nuclear Safety Commission, which is reviewing their designs.

"Canadians working together, like we are here today, from coast to coast, can play an even larger role in addressing climate change in Canada and around the world," Moe said.  

Canada's Paris targets are to lower total emissions 30 per cent below 2005 levels by 2030, and nuclear's role in climate goals has been emphasized by the federal minister in recent remarks. Moe says the reactors would help Saskatchewan reach a 70 per cent reduction by that year.

The provinces' three energy ministries will meet in the new year to discuss how to move forward and by the fall a fully-fledged strategy for the reactors is expected to be ready.

However, don't expect to see them popping up in a nearby field anytime soon. It's estimated it will take five to 10 years before they're built. 

Ford lauds economic possibilities
The provincial leaders said it could be an opportunity for economic growth, estimating the Canadian market for this energy at $10 billion and the global market at $150 billion.

Ford called it an "opportunity for Canada to be a true leader." At a time when Ottawa and the provinces are at odds, Higgs said it's the perfect time to show unity. 

"It's showing how provinces come together on issues of the future." 

P.E.I. premier predicts unity at Toronto premiers' meeting
No other premiers have signed on to the deal at this point, but Ford said all are welcome and "the more, the merrier."

But developing new energy technologies is a daunting task. Higgs admitted the project will need national support of some kind, though he didn't specify what. The agreement signed by the premiers is also not binding. 

About 8.6 per cent of Canada's electricity comes from coal-fired generation. In New Brunswick that figure is much higher — 15.8 per cent — and New Brunswick's small-nuclear debate has intensified as New Brunswick Premier Blaine Higgs has said he worries about his province's energy producers being hit by the federal carbon tax.

Ontario has no coal-fired power plants, and OPG's SMR commitment aligns with its clean electricity strategy today. In Saskatchewan, burning coal generates 46.6 per cent of the province's electricity.

How would it work?
The federal government describes small modular reactors (SMRs) as the "next wave of innovation" in nuclear energy technology, and collaborations like the OPG and TVA partnership are advancing development efforts, and an "important technology opportunity for Canada."

Traditional nuclear reactors used in Canada typically generate about 800 megawatts of electricity, and Ontario is exploring new large-scale nuclear plants alongside SMRs, or enough to power about 600,000 homes at once (assuming that 1 megawatt can power about 750 homes).

The International Atomic Energy Agency (IAEA), the UN organization for nuclear co-operation, considers a nuclear reactor to be "small" if it generates under 300 megawatts.

Designs for small reactors ranging from just 3 megawatts to 300 megawatts have been submitted to Canada's nuclear regulator, the Canadian Nuclear Safety Commission, for review as part of a pre-licensing process, while plans for four SMRs at Darlington outline a potential build-out pathway that regulators will assess.

Ford rallying premiers to call for large increase in federal health transfers
Such reactors are considered "modular" because they're designed to work either independently or as modules in a bigger complex (as is already the case with traditional, larger reactors at most Canadian nuclear power plants). A power plant could be expanded incrementally by adding additional modules.

Modules are generally designed to be small enough to make in a factory and be transported easily — for example, via a standard shipping container.

In Canada, there are three main areas where SMRs could be used:

Traditional, on-grid power generation, especially in provinces looking for zero-emissions replacements for CO2-emitting coal plants.
Remote communities that currently rely on polluting diesel generation.
Resource extraction sites, such as mining and oil and gas.

Britain's National Grid Drops China-Based Supplier Over Cybersecurity Fears

National Grid Cybersecurity Component Removal signals NCSC and GCHQ oversight of critical infrastructure, replacing NR Electric and Nari Technology grid control systems to mitigate supply chain risk, cyber threats, and blackout risk.

 

Key Points

A UK move to remove China-linked grid components after NCSC/GCHQ advice, reducing cyber and blackout risks.

✅ NCSC advice to remove NR Electric components

✅ GCHQ-linked review flags critical infrastructure risks

✅ Aims to cut blackout risk and supply chain exposure

 

Britain's National Grid has started removing components supplied by a unit of China-backed Nari Technology's from the electricity transmission network over cybersecurity fears, reflecting a wider push on protecting the power grid across critical sectors.

The decision came in April after the utility sought advice from the National Cyber Security Center (NCSC), a branch of the nation's signals intelligence agency, Government Communications Headquarters (GCHQ), amid campaigns like the Dragonfly campaign documented by Symantec, the newspaper quoted a Whitehall official as saying.

National Grid declined to comment citing "confidential contractual matters." "We take the security of our infrastructure very seriously and have effective controls in place to protect our employees and critical assets, while preparing for an independent operator transition in Great Britain, to ensure we can continue to reliably, safely and securely transmit electricity," it said in a statement.

The report said an employee at the Nari subsidiary, NR Electric Company-U.K., had said the company no longer had access to sites where the components were installed, at a time when utilities worldwide have faced control-room intrusions by state-linked hackers, and that National Grid did not disclose a reason for terminating the contracts.

It quoted another person it did not name as saying the decision was based on NR Electric Company-U.K.'s components that help control and balance the grid, respond to work-from-home demand shifts, and minimize the risk of blackouts.

It was unclear whether the components remained in the electricity transmission network, the report said, amid reports of U.S. power plant breaches that have heightened vigilance.

NR Electric Company-U.K., GCHQ and the Chinese Embassy in London did not immediately respond to requests for comment outside of business hours.

Britain's Department for Energy Security and Net Zero said that it did not comment on the individual business decisions taken by private organizations. "As a government department we work closely with the private sector to safeguard our national security, and to support efforts to fast-track grid connections across the network," it said in a statement.

Competition in Electricity Has Been Good for Consumers and Good for the Environment

Electricity Market Competition drives lower wholesale prices, stable retail rates, better grid reliability, and faster emissions cuts as deregulation and renewables adoption pressure utilities, improve efficiency, and enhance consumer choice in power markets.

 

Key Points

Electricity market competition opens supply to rivals, lowering prices, improving reliability, and reducing emissions.

✅ Wholesale prices fell faster in competitive markets

✅ Retail rates rose less than in monopoly states

✅ Fewer outages, shorter durations, improved reliability

 

By Bernard L. Weinstein

Electricity used to be boring.  Public utilities that provided power to homes and businesses were regulated monopolies and, by law, guaranteed a fixed rate-of-return on their generation, transmission, and distribution assets. Prices per kilowatt-hour were set by utility commissions after lengthy testimony from power companies, wanting higher rates, and consumer groups, wanting lower rates.

About 25 years ago, the electricity landscape started to change as economists and others argued that competition could lead to lower prices and stronger grid reliability. Opponents of competition argued that consumers weren’t knowledgeable enough about power markets to make intelligent choices in a competitive pricing environment. Nonetheless, today 20 states have total or partial competition for electricity, allowing independent power generators to compete in wholesale markets and retail electric providers (REPs) to compete for end-use customers, a dynamic echoed by the Alberta electricity market across North America. (Transmission, in all states, remains a regulated natural monopoly).

A recent study by the non-partisan Pacific Research Institute (PRI) provides compelling evidence that competition in power markets has been a boon for consumers. Using data from the U.S. Energy Information Administration (EIA), PRI’s researchers found that wholesale electricity prices in competitive markets have been generally declining or flat, prompting discussions of free electricity business models, over the last five years. For example, compared to 2015, wholesale power prices in New England have dropped more than 44 percent, those in most Mid-Atlantic States have fallen nearly 42 percent, and in New York City they’ve declined by nearly 45 percent. Wholesale power costs have also declined in monopoly states, but at a considerably slower rate.

As for end-users, states that have competitive retail electricity markets have seen smaller price increases, as consumers can shop for electricity in Texas more cheaply than in monopoly states. Again, using EIA data, PRI found that in 14 competitive jurisdictions, retail prices essentially remained flat between 2008 and 2020. By contrast, retail prices jumped an average of 21 percent in monopoly states.  The ten states with the largest retail price increases were all monopoly-based frameworks. A 2017 report from the Retail Energy Supply Association found customers in states that still have monopoly utilities saw their average energy prices increase nearly 19 percent from 2008 to 2017 while prices fell 7 percent in competitive markets over the same period.

The PRI study also observed that competition has improved grid reliability, the recent power disruptions in California and Texas, alongside disruptions in coal and nuclear sectors across the U.S., notwithstanding. Looking at two common measures of grid resiliency, PRI’s analysis found that power interruptions were 10.4 percent lower in competitive states while the duration of outages was 6.5 percent lower.

Citing data from the EIA between 2008 and 2018, PRI reports that greenhouse gas emissions in competitive states declined on average 12.1 percent compared to 7.3 percent in monopoly states. This result is not surprising, and debates over whether Israeli power supply competition can bring cheaper electricity mirror these dynamics.  In a competitive wholesale market, independent power producers have an incentive to seek out lower-cost options, including subsidized renewables like wind and solar. By contrast, generators in monopoly markets have no such incentive as they can pass on higher costs to end-users. Perhaps the most telling case is in the monopoly state of Georgia where the cost to build nuclear Plant Vogtle has doubled from its original estimate of $14 billion 12 years ago. Overruns are estimated to cost Georgia ratepayers an average of $854, and there is no definite date for this facility to come on line. This type of mismanagement doesn’t occur in competitive markets.

Unfortunately, some critics are attempting to halt the momentum for electricity competition and have pointed to last winter’s “deep freeze” in Texas that left several million customers without power for up to a week. But this example is misplaced. Power outages in February were the result of unprecedented and severe weather conditions affecting electricity generation and fuel supply, and numerous proposals to improve Texas grid reliability have focused on weatherization and fuel resilience; the state simply did not have enough access to natural gas and wind generation to meet demand. Competitive power markets were not a factor.

The benefits of wholesale and retail competition in power markets are incontrovertible. Evidence shows that households and businesses in competitive states are paying less for electricity while grid reliability has improved. The facts also suggest that wholesale and retail competition can lead to faster reductions in greenhouse gas emissions. In short, competition in power markets is good for consumers and good for the environment.

More red ink at Manitoba Hydro as need for new power generation looms

Manitoba NDP Energy Financing Strategy outlines public ownership of renewables, halts private wind farms, stabilizes hydroelectric rates, and addresses Manitoba Hydro deficits amid drought, export revenue declines, and rising demand for grid reliability.

 

Key Points

A plan to fund public renewables, pause private wind, and stabilize Manitoba Hydro rates, improving utility finances.

✅ Public ownership favored over private wind contracts

✅ Focus on rate freeze and Manitoba Hydro debt management

✅ Addresses drought impacts, export revenue declines, rising demand

 

Manitoba's NDP administration has declared its intention to formulate a strategy for financing new energy ventures, following a decision to halt the development of additional private-sector wind farms and to extend a pause on new cryptocurrency connections amid grid pressures. This plan will accompany efforts to stabilize hydroelectric rates and manage the financial obligations of the province's state-operated energy company.

Finance Minister Adrien Sala, overseeing Manitoba Hydro, shared these insights during a legislative committee meeting on Thursday, emphasizing the government's desire for future energy expansions to remain under public ownership, even as Ontario moves to reintroduce renewable energy projects after prior cancellations, and expressing trust in Manitoba Hydro's governance to realize these goals.

This announcement was concurrent with Manitoba Hydro unveiling increased financial losses in its latest quarterly report. The utility anticipates a $190-million deficit for the fiscal year ending in March, marking a $29 million increase from its previous forecast and a significant deviation from an initial $450 million profit expectation announced last spring. Contributing factors to this financial downturn include reduced hydroelectric power generation due to drought conditions, diminished export revenues, and a mild fall season impacting heating demand.

The recent financial update aligns with a period of significant changes at Manitoba Hydro, initiated by the NDP government's board overhaul following its victory over the former Progressive Conservative administration in the October 3 election, and comes as wind projects are scrapped in Alberta across the broader Canadian energy landscape.

Subsequently, the NDP-aligned board discharged CEO Jay Grewal, who had advocated for integrating wind energy from third-party sources, citing competitive wind power trends, to promptly address the province's escalating energy requirements. Grewal's approach, though not unprecedented, sought to offer a quicker, more cost-efficient alternative to constructing new Manitoba Hydro dams, highlighting an imminent energy production shortfall projected for as early as 2029.

The opposition Progressive Conservatives have criticized the NDP for dismissing the wind power initiative without presenting an alternate solution, warning about costly cancellation fees seen in Ontario when projects are halted, and emphasizing the urgency of addressing the predicted energy gap.

In response, Sala reassured that the government is in the early stages of policy formulation, reflecting broader electricity policy debates in Ontario about how to fix the power system, and criticized the previous administration for its inaction on enhancing generation capacity during its tenure.

Manitoba Hydro has named Hal Turner as the acting CEO while it searches for Grewal's successor, following controversies such as Solar Energy Program mismanagement raised by a private developer. Turner informed the committee that the utility is still deliberating on its approach to new energy production and is exploring ways to curb rising demand.

Expressing optimism about collaborating with the new board, Turner is confident in finding a viable strategy to fulfill Manitoba's energy needs in a safe and affordable manner.

Additionally, the NDP's campaign pledge to freeze consumer rates for a year remains a priority, with Sala committing to implement this freeze before the next provincial election slated for 2027.

"Energy war": Ukraine tries to protect electricity supply before winter

Ukraine Power Grid Resilience details preparations for winter blackouts, airstrike defense, decentralized generation, backup generators, battery storage, DTEK restorations, EU grid synchronization, and upgraded air defenses to safeguard electricity, heating, water, and essential services.

 

Key Points

Ukraine Power Grid Resilience is a strategy to harden energy systems against winter attacks and outages.

✅ DTEK repairs, backup equipment, and fortified plants across Ukraine

✅ Expanded air defenses targeting missiles and attack drones

✅ EU grid sync enables emergency imports and power trading

 

Oleksandr Gindyuk is determined not to be caught off guard if electricity supplies fail again this winter. When Russia pounded Ukraine’s power grid with widespread and repeated waves of airstrikes last year, causing massive rolling blackouts, his wife had just given birth to their second daughter.

“It was quite difficult,”  Gindyuk, who lives with his family in the suburbs of the capital, Kyiv, told CNN. “There is no life in our house if there is no electricity. Without electricity, we have no water, light or heating.”

He has spent the summer preparing for Russia to repeat its strategy, which was designed to sow terror and make life unsustainable, robbing Ukrainians of heat, water and health services. “We are totally ready — we have a diesel generator and a powerful 9 kWh battery. We are not scared, we are ready,” Gindyuk told CNN.

As families like Gindyuk’s gird themselves for the possibility of another dark winter, Ukraine has been rushing to rebuild and, drawing on protecting the grid lessons, protect its fragile energy infrastructure.

The summer provided a respite for Ukraine’s power grid. Russia focused its attacks on military targets and on ports on the Black Sea and the Danube River, to hinder Ukraine’s efforts to move grain and choke off an important income stream.

As the days grow shorter and the temperatures drop, Russia has another opportunity to try to break Ukrainian resilience with punishing blackouts. But this winter, defense and energy officials say Ukraine is better prepared.

With limited Ukrainian air defenses in operation last year, Russia was able to target and hit the energy grid easily, including during missile and drone assaults on Kyiv’s grid that strained responders.

“The Russians may use a combination of missile weapons and attack UAVs (unmanned aerial vehicles, or drones). These will definitely not be such primitive attacks as last year. It will be difficult for the Russians to achieve a result - we are also preparing and understanding how they act.”

DTEK, the country’s largest private energy company, has spent the past seven months restoring infrastructure, trying to boost output and bolstering defenses at its facilities across Ukraine, mindful of Russian utility hacks reported elsewhere.

“We restored what could be restored, bought back-up equipment and installed defenses around power plants, as Russian-linked breaches at US plants have underscored risks,” DTEK chief executive Maxim Timchenko told CNN.

The company generates around a quarter of Ukraine’s electricity and runs 40% of its grid network, making it a prime target for Russian attacks. Four DTEK employees have been killed while on duty and its power stations have been attacked nearly 300 times since the start of the full-scale invasion, according to the company. “Last winter, determination carried us through. This winter we are stronger, and our people are more experienced,” Timchenko said.

Russia launched 1,200 attacks on Ukraine’s energy system between October 2022 and April 2023, with every thermal power and hydro-electric plant in the country sustaining some damage, according to DTEK.

In a damage assessment report released in June, the United Nations Development Programme said that Ukraine’s power generation capacity had been reduced to about half of what it was before Russia’s full-scale invasion. “Ukraine’s power system continues to operate in an emergency mode, which affects both power grids and generation, amid rising concerns about state-backed grid hacking worldwide,” a news release accompanying the report said.

The report also laid out a roadmap to rebuilding the energy sector, prioritizing decentralization, renewable energy sources and greater integration with the European Union. Ukraine has been hooked into the EU’s power grid since the full-scale invasion, allowing it to synchronize and trade power with the bloc. But the massive wave of attacks on energy infrastructure last winter threw that balance off kilter.
