While fall temperatures have been mild, winter weather is just around the corner. Recently, ComEd announced that investments to strengthen and modernize its electrical delivery system are helping to improve power reliability and ensuring that the utility is ready to serve its customers this winter.

“The work done by ComEd to modernize and storm harden the electrical grid has contributed to record-breaking reliability over the last two years,” said Terence R. Donnelly, executive vice-president and chief operating officer for ComEd. “As we approach the winter and the potential for heavy snow and ice, this work will help ensure that our customers have reliable energy to meet their needs.”

With the passage of the Smart Grid law by the Illinois General Assembly in 2011, ComEd embarked on a $2.6 billion program to modernize the power system in northern Illinois. Through investments in smart switches that reroute power around potential problem areas, new storm hardening and vegetation management solutions, and cable replacement, as well as other system improvement programs, more than 5.6 million customer interruptions have been avoided since 2012.

Last year alone, more than 1.5 million interruptions did not occur due to the reliability improvements ComEd is making to its system. In fact, despite severe weather conditions, including several tornadoes earlier this year, ComEd has produced record reliability for the first half of 2015. Due to system improvements, more than 1.6 million customer interruptions have been avoided so far this year.

ComEdÂ’s proposed legislation, known as ComEdÂ’s Future Energy Plan, builds on the benefits of the smart grid through, among other improvements, the development of six microgrids which will provide additional resiliency and reliability in the face of extreme weather or man-made events. The plan also calls for expanded support for renewable energy in Illinois and ensures that energy consumers and the state economy will continue to benefit from affordable power, a more secure and resilient grid.

“We are continuing to explore opportunities to bring new technology to the grid that will improve reliability,” said Donnelly. “Our Future Energy Plan delivers value to our customers through clean energy, energy savings, grid resiliency and customer choice.”

ComEd also offers the following no costs/low costs tips to help customers safely prepare their homes for winter weather, manage their energy usage and reduce electricity costs.

Denmark's climate-friendly electricity record is incinerated

Denmark Renewable Energy Outlook assesses Eurostat ranking, district heating and trash incineration, EV adoption, wind turbine testing expansions, and electrification to cut CO2, aligning policies with EU 2050 climate goals and green electricity usage.

 

Key Points

A brief analysis of Denmark's green power use, electrification, EVs, and policies needed to meet EU 2050 CO2 goals.

✅ Eurostat rank low due to trash incineration in district heating.

✅ EV adoption stalled after tax reinstatement, slowing electrification.

✅ Wind test centers expanded; electrification could cut 95% CO2.

 

Denmark’s low ranking in the latest figures from Eurostat regarding climate-friendly electricity, which places the country in 32nd place out of 40 countries, is partly a result of the country’s reliance on the incineration of trash to warm our homes via long-established district heating systems.

Additionally, there are not enough electric vehicles – a recent increase in sales was halted in 2016 when the government started to phase back registration taxes scrapped in 2008, and Europe’s EV slump underscores how fragile momentum can be.

 

Not enough green electricity being used

Denmark is good at producing green electricity, reports Politiken, but it does not use enough, and amid electricity price volatility in Europe this is bad news if it wants to fulfil the EU’s 2050 goal to eliminate CO2 emissions.

 

A recent report by Eurelectric and McKinsey demonstrates that if heating, transport and industry were electrified, reflecting a broader European push for electrification across the energy system, 95 percent of the country’s CO2 emissions could be eliminated by that date.

 

Wind turbine testing centre expansion approved

Parliament has approved the expansion of two wind turbine centres in northwest Jutland, supporting integration as e-mobility drives electricity demand in the coming years. The centres in Østerild and Høvsøre will have the capacity to test nine and seven turbines, measuring 330 and 200 metres in size (up from 250 and 165) respectively. The Østerild expansion should be completed in 2019, while Høvsøre ​​will have to wait a little longer.

 

Third on the Environmental Performance Index

Denmark finished third on the latest Environmental Performance Index, finishing only behind Switzerland and France. Its best category ranking was third for Environmental Health, and comparative energy efficiency benchmarking can help contextualize progress. Elsewhere, it ranked 11th for Ecosystem Vitality, 18th for Biodiversity and Habitat, 94th for Forests, 87th for Fisheries, 25th for Climate and Energy and 37th for Air Pollution, 14th for Water Resources and 7th for Agriculture.

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.

Electricity deal clinches $100M bitcoin mining operation in Medicine Hat

Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.

 

Key Points

A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.

✅ 42 MW electricity from city; land lease near Unit 16

✅ Hut 8 expands to 60.7 MW; blockchain data centres

✅ 100 temporary jobs; 42 ongoing roles in Alberta

 

The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.

The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.

The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.

"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."

In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.

Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.

Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.

We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.

"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."

Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.

Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.

The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.

Why Atomic Energy Is Heating Up Again

Nuclear Power Revival drives decarbonization, climate change mitigation, and energy security with SMRs, Generation IV designs, baseload reliability, and policy support, complementing renewables to meet net-zero targets and growing global electricity demand.

 

Key Points

A global shift back to nuclear energy, leveraging SMRs and advanced reactors to cut emissions and enhance energy security.

✅ SMRs offer safer, modular, and cost-effective deployment.

✅ Provides baseload power to complement intermittent renewables.

✅ Policy support and investments accelerate advanced designs.

 

In recent years, nuclear power has experienced a remarkable revival in public interest, policy discussions, and energy investment. Once overshadowed by controversies surrounding safety, waste management, and high costs, nuclear energy is now being reexamined as a vital component of the global energy transition, despite recurring questions such as whether it is in decline from some commentators. Here's why nuclear power is "so hot" right now:

1. Climate Change Urgency

One of the most compelling reasons for the renewed interest in nuclear energy is the urgent need to address climate change. Unlike fossil fuels, nuclear power generates electricity with zero greenhouse gas emissions during operation. As countries rush to meet net-zero carbon targets, evidence that net-zero may require nuclear is gaining traction, and nuclear offers a reliable, large-scale alternative to complement renewable energy sources like wind and solar.

2. Energy Security and Independence

Geopolitical tensions and supply chain disruptions have exposed vulnerabilities in relying on imported fossil fuels, and Europe's shrinking nuclear capacity has sharpened concerns over resilience. Nuclear power provides a domestic, stable energy source that can operate independently of volatile global markets. For many nations, this has become a strategic priority, reducing dependence on politically sensitive energy imports.

3. Advances in Technology

Modern innovations in nuclear technology are transforming the industry. Small Modular Reactors (SMRs) are leading the way as part of next-gen nuclear innovation, offering safer, more affordable, and flexible options for nuclear deployment. Unlike traditional large-scale reactors, SMRs can be built faster, scaled to specific energy needs, and deployed in remote or smaller markets.

Additionally, advances in reactor designs, such as Generation IV reactors and fusion research, promise to address longstanding concerns like waste management and safety. For example, some new designs can recycle spent fuel or run on alternative fuels, significantly reducing radioactive waste.

4. Public Perception Is Shifting

Public opinion on nuclear power is also changing. While the industry faced backlash after high-profile incidents like Chernobyl and Fukushima, increasing awareness of climate change and energy security is prompting many to reconsider, including renewed debates such as Germany's potential nuclear return in policy circles. A younger, climate-conscious generation views nuclear energy not as a relic of the past, but as an essential tool for a sustainable future.

5. Renewables Alone Are Not Enough

While renewable energy sources like solar and wind have grown exponentially, their intermittent nature remains a challenge. Energy storage technologies, such as batteries, have not yet matured enough to fully bridge the gap. Nuclear power, with its ability to provide constant, "baseload" energy, as France's fleet demonstrates in practice, serves as an ideal complement to variable renewables in a decarbonized energy mix.

6. Government Support and Investment

Policymakers are taking action to bolster the nuclear sector. Many countries are including nuclear energy in their clean energy plans, offering subsidies, grants, and streamlined regulations to accelerate its deployment. For instance, the United States has allocated billions of dollars to support advanced nuclear projects, the UK's green industrial revolution outlines support for upcoming reactor waves, while Europe has classified nuclear power as "sustainable" under its green taxonomy.

7. Global Energy Demand Is Growing

As populations and economies grow, so does the demand for electricity. Developing nations, in particular, are seeking energy solutions that can support industrialization while limiting environmental impact. Nuclear energy is being embraced as a way to meet these dual objectives, especially in regions with limited access to consistent renewable energy resources.

Challenges Ahead

Despite its potential, nuclear energy is not without its challenges. High upfront costs, lengthy construction timelines, and public concerns over safety and waste remain significant hurdles. The industry will need to address these issues while continuing to innovate and build public trust.

Nuclear power's resurgence is driven by its unique ability to tackle some of the most pressing challenges of our time: climate change, energy security, and the growing demand for electricity. With advances in technology, changing perceptions, and robust policy support, nuclear energy is poised to play a critical role in the global transition to a sustainable and secure energy future.

In a world increasingly shaped by the need for clean and reliable power, nuclear energy has once again become a hot topic—and for good reason.

Ukraine's parliament backs amendments to electricity market law

Ukraine Electricity Market Price Caps empower the regulator, the National Commission, to set marginal prices on day-ahead, intraday, and balancing markets, stabilize competition, support thermal plants, and sustain the heating season via green tariff obligations.

 

Key Points

Regulatory limits set by the National Commission to curb price spikes, ensure competition, and secure heat supply.

✅ Sets marginal prices for day-ahead, intraday, balancing markets

✅ Mitigates collusion risks; promotes effective competition

✅ Ensures TPP operation and heat supply during heating season

 

The Verkhovna Rada, Ukraine's parliament, has adopted at first reading a draft law that proposes giving the National Commission for State Regulation of Energy and Public Utilities the right to set marginal prices in the electricity market, amid EU market revamp plans that aim to reshape pricing, until 2023.

A total of 259 MPs voted for the document at a parliament meeting on Tuesday, November 12, amid electricity import pressures that have tested the grid, according to an Ukrinform correspondent.

Bill No. 2233 introducing amendments to the law on the electricity market provides for the legislative regulation of the mechanism for fulfilling special obligations for the purchase of electricity at a "green" tariff, preventing the uncontrolled growth of electricity prices due to the lack of effective competition, including recent price-fixing allegations that have raised concerns, ensuring heat supply to consumers during the heating period by regulating the issue of the functioning of thermal power plants in the new electricity market.

It is proposed to introduce respective amendments to the law of Ukraine on the electricity market, alongside steps toward synchronization with ENTSO-E to enhance system stability.

In particular, the draft law gives the regulator the right for the period until July 1, 2023 to set marginal prices on the day-ahead market, the intraday market and the balancing market for each trade zone, reflecting similar EU fixed-price contract initiatives being discussed, and to decide on the obligation for producers to submit proposals (applications) for the sale of electricity on the day-ahead market.

Lawmakers think that the adoption of the bill and empowering the regulator to set marginal prices in the relevant segments of the electricity market will prevent, even as rolling back prices in Europe remains difficult for policymakers, "an uncontrolled increase in electricity prices due to the lack of effective competition or collusion between market players, as well as regulate the issue of the functioning of thermal power plants during the autumn and winter period, which is a necessary prerequisite for providing heat to consumers during the heating period."

The new model of the electricity market was launched on July 1 as the UK weighs decoupling gas and power prices to shield consumers, in accordance with the provisions of the law on the electricity market, adopted in 2017.
