Advanced metering infrastructure (AMI) technology, combined with geographic information system (GIS) software, has significantly cut operating costs for meter reading at UnitilÂ’s distribution operating subsidiaries in Massachusetts and New Hampshire.

ESRIÂ’s ArcGIS has given the utility greater insight about the behavior of its customers, the integrity of its system, and the direction it should take for improved performance.

UnitilÂ’s AMI incorporates ArcGIS to process data captured from a bidirectional advanced metering system as well as data accessed from the customer information system (CIS). Based on the first yearÂ’s success, Unitil anticipates a payback within five years in labor savings and process efficiencies.

In 2004, Unitil migrated from a CAD-based mapping system to ArcGIS with Telvent Miner & MinerÂ’s ArcFM software for asset management. Recently, the integration of GIS with AMI has extended the value of GIS for the company.

“Suddenly, GIS became more to our people than making pretty maps,” explains Beth Picardi, Unitil’s GIS analyst. “The primary objective of the AMI project was to automate meter reading. In addition to those savings, we have gained a wealth of data on system performance that can be leveraged by integrating AMI with ArcGIS and other company enterprise systems.”

In 2007, Unitil deployed a system wide gas and electric AMI for 115,000 customers. Meters were retrofitted with endpoints from Hunt Technologies, LLC, which utilize power line carrier, fixed network technology to monitor and receive daily usage data. AMI data layers are created by combining data from UnitilÂ’s CIS database with GPS meter coordinates. This information is the basis for a variety of analyses useful to engineering and operations within the company.

“Viewing this data in GIS has led to an intuitive understanding of system performance,” notes Picardi. “Meters reporting a loss of communication have allowed us to research and better understand the need for an outage management system and how AMI can augment it. In addition to outages, GIS allows us to visualize momentary outages, end-of-line voltage readings, and reliability performance metrics directly from AMI.”

Unitil continues to find new ways to leverage its AMI data in GIS, giving the company a better understanding of its customer needs and improving its ability to proactively meet those needs. One example is the enhancement of vegetation management strategies by overlaying historical tree trimming data layers with momentary outage data. Soon, it will be possible to evaluate the local system benefits of considering various demand-side revenue policies such as time-of-use billing or demand response.

“GIS and AMI integration is making GIS an enterprise solution here at Unitil,” concludes Picardi.

"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.

Sudbury, Ont., eco groups say sustainability is key to grid's future

Sudbury Electrification and Grid Expansion is driving record power demand, EV charging, renewable energy planning, IESO forecasts, smart grid upgrades, battery storage, and industrial electrification, requiring cleaner power plants and transmission capacity in northern Ontario.

 

Key Points

Rising electricity demand and clean energy upgrades in Sudbury to power EVs, industry, and a smarter, expanded grid.

✅ IESO projects system size may need to more than double

✅ EVs and smart devices increase peak and off-peak load

✅ Battery storage and V2G can support reliability and resiliency

 

Sudbury, Ont., is consuming more power than ever, amid an electricity supply crunch in Ontario, according to green energy organizations that say meeting the demand will require cleaner energy sources.

"This is the welfare of the entire city on the line and they are putting their trust in electrification," said David St. Georges, manager of communications at reThink Green, a non-profit organization focused on sustainability in Sudbury.

According to St. Georges, Sudbury and northern Ontario can meet the growing demand for electricity to charge clean power for EVs and smart devices. 

According to the Independent Electricity System Operator (IESO), making a full switch from fossil fuels to other renewable energy sources could require more power plants, while other provinces face electricity shortages of their own.

"We have forecasted that Ontario's electricity system will need significant expansion to meet this, potentially more than doubling in size," the IESO told CBC News in an emailed statement.

Electrification in the industrial sector is adding greater demand to the electrical grid as electric cars challenge power grids in many regions. Algoma Steel in Sault Ste. Marie and ArcelorMittal Dofasco in Hamilton both aim to get electric arc furnaces in operation. Together, those projects will require 630 megawatts.

"That's like adding four cities the size of Sudbury to the grid," IESO said.

Devin Arthur, chapter president of the Electric Vehicle society in Greater Sudbury, said the city is coming full circle with fully electrifying its power grid, reflecting how EVs are a hot topic in Alberta and beyond.

"We're going to need more power," he said.

"Once natural gas was introduced, that kind of switched back, and everyone was getting out of electrification and going into natural gas and other sources of power."

Despite Sudbury's increased appetite for electricity, Arthur added it's also easier to store now as Ontario moves to rely on battery storage solutions.

"What that means is you can actually use your electric vehicle as a battery storage device for the grid, so you can actually sell power from your vehicle that you've stored back to the grid, if they need that power," he said.

Harneet Panesar, chief operating officer for the Ontario Energy Board, told CBC the biggest challenge to going green is seeing if it can work around older infrastructure, while policy debates such as Canada's 2035 EV sales mandate shape the pace of change.

"You want to make sure that you're building in the right spot," he said.

"Consumers are shifting from combustion engines to EV drivetrains. You're also creating more dependency. At a very high level, I'm going to say it's probably going to go up in terms of the demand for electricity."

Fossil fuels are the first to go for generating electricity, said St. Georges.

"But we're not there yet, because it's not a light switch solution. It takes time to get to that, which is another issue of electrification," he said.

"It's almost impossible for us not to go that direction."

Sudbury Hydro crews aim to reconnect service after storm

Sudbury Microburst Power Outage strains hydro crews after straight-line winds; New Sudbury faces downed power lines, tree damage, and hazardous access as restoration efforts, mutual aid, and safety protocols aim to reconnect customers by weekend.

 

Key Points

A microburst downed lines in New Sudbury, cutting power as crews tackle hazardous access and complex repairs.

✅ Straight-line winds downed poles, trees, and service lines

✅ Crews face backyard access hazards, complex reconnections

✅ Mutual aid linemen, arborists, and crane work speed restoration

 

About 300 Sudbury Hydro customers are still without power Thursday after Monday's powerful microburst storm, part of a series of damaging storms in Ontario seen across the province.

The utility's spokesperson, Wendy Watson, says the power in the affected New Sudbury neighbourhoods should be back on by the weekend, even as Toronto power outages persisted in a recent storm.

The storm, which Environment Canada said was classified as a microburst or straight line wind damage, similar to a severe windstorm in Quebec, downed a number of power lines in the city.

Now crews are struggling with access to the lines, a challenge that BC Hydro's atypical storm response also highlighted, as they work to reconnect service in the area.

"In some cases, you can't get to someone's back yard, or you have to go through the neighbour's yard," Watson said.

"We have one case where [we had] equipment working over a swimming pool. It's dicey, it's really dirty and it's dangerous."

Veteran arborist Jim Allsop told CBC News he hasn't seen damage like this in his 30-plus years in the business.

"I don't know how many we've done up to date, but I have another 35 trees on houses," Allsop said. "We'll be probably another week."

"We've rented a crane to help speed up the process, and increase safety, and we're getting five or six done in our 12-hour days."

Scott Aultman, a lineman with North Bay Hydro, said he has seen a few storms in his career, and isn't usually surprised by extensive damage a storm can cause.

"When you see a trailer on its side, you know, you don't see that every day," Aultman said.

But during the clean up, Aultman said the spirit of camaraderie runs high with crews from different areas, as seen when Canadian crews helped Florida during Hurricane Irma.

"We were pumped. It's part of the trade, everybody gets together," Aultman said. "We had a big storm in 2006 and the Sudbury guys were up helping us, so it's great, it's nice to be able to return the favour and help them out."

Electricity demand set to reduce if UK workforce self-isolates

UK Energy Networks Coronavirus Contingency outlines ESO's lockdown electricity demand forecast, reduced industrial and commercial load, rising domestic use, Ofgem guidance needs, grid resilience, control rooms, mutual aid, and backup centers.

 

Key Points

A coordinated plan with ESO forecasts, safeguards, and mutual aid to keep power and gas services during a lockdown.

✅ ESO forecasts lower industrial use, higher domestic demand

✅ Control rooms protected; backup sites and cross-trained staff

✅ Mutual aid and Ofgem coordination bolster grid resilience

 

National Grid ESO is predicting a reduction in electricity demand, consistent with residential use trends observed during the pandemic, in the case of the coronavirus spread prompting a lockdown across the country.

Its analysis shows the reduction in commercial and industrial use would outweigh an upsurge in domestic demand, mirroring Ontario demand data seen as people stayed home, according to similar analyses.

The prediction was included in an update from the Energy Networks Association (ENA), in which it sought to reassure the public that contingency plans are in place, reflecting utility disaster planning across electric and gas networks, to ensure services are unaffected by the coronavirus spread.

The body, which represents the UK's electricity and gas network companies, said "robust measures" had been put in place to protect control rooms and contact centres, similar to staff lockdown protocols considered by other system operators, to maintain resilience. To provide additional resilience, engineers have been trained across multiple disciplines and backup centres exist should operations need to be moved if, for example, deep cleaning is required, the ENA said.

Networks also have industry-wide mutual aid arrangements, similar to grid response measures outlined in the U.S., for people and the equipment needed to keep gas and electricity flowing.

ENA chief executive, David Smith, said, echoing system reliability assurances from other markets: "The UK's electricity and gas network is one of the most reliable in the world and network operators are working with the authorities to ensure that their contingency plans are reviewed and delivered in accordance with the latest expert advice. We are following this advice closely and reassuring customers that energy networks are continuing to operate as normal for the public."

Utility Week spoke to a senior figure at one of the networks who reiterated the robust measures in place to keep the lights on, even as grid alerts elsewhere highlight the importance of contingency planning. However, they pleaded for more clarity from Ofgem and government on how its workers will be treated if the coronavirus spread becomes a pandemic in the UK.

Shopping for electricity is getting cheaper in Texas

Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.

 

Key Points

Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.

✅ Deregulated areas saw 17.4% residential price declines since 2006

✅ Regulated zones experienced a 5.5% increase over the same period

✅ Competitive shopping narrowed the gap; Texas averaged below US

 

Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.

About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.

The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.

Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.

Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.

“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”

The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.

Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.
