The MEREGIO smart grid project has been selected by the Federal Ministry of Economics and Technology of Germany as a winner of Germany’s “E-Energy” funding competition.

The project, currently underway, is supported by the German government after an independent jury selected MEREGIO and five other outstanding projects for funding.

MEREGIO – “Minimum Emission Region” – is focused on the development of a minimum emission certificate for the model region Karlsruhe/Stuttgart in Germany. The aim of the certification is the complete elimination of CO2 emissions caused by heating and electrical power consumption. It is a project strongly supported by ABB.

The gathered data is intended to motivate other regions to actively reduce their greenhouse gas emissions and promote specific measures to cut CO2 production.

For each household, a smart meter with bi-directional broadband communication interfaces delivers a high level of transparency. Within the pilot project, these meters will be installed at 800 consumer sites, 100 generation units and 100 storages for electrical energy.

A more efficient integration of yield-dependent energy resources in the power grid represents another main toehold for the reduction of CO2 emissions. Therefore customers will receive price signals as motivation for energy consumption. Price signals are particularly suitable if regional bottlenecks force network operators to switch off generation units to ensure network security.

In northern Germany, this situation already regularly occurs in the 60 and 110 kilovolt grid. Since there are currently no measure and communication technologies available, it is the function of restrictive grid codes to avoid such bottlenecks in subordinate voltage levels. Within the MEREGIO project, meters and communication infrastructure will be used to detect the state of the grid on the medium- and low-voltage level. If bottlenecks are detected, the systems automatically set price signals as prevention and – if necessary – power plants will be switched off.

As it will not possible to change existing grid codes within the pilot project, bottlenecks in low- and medium-voltage level will not occur in reality. Therefore, MEREGIO will also simulate load flows in a virtual network model. This online-simulation will be used to analyze how the use of CO2 free energy resources could be maximized in a market-oriented way if grid codes would change.

Another approach to cut CO2 emissions in MEREGIO involves the increase of network capacity and the reduction of network losses by introducing a marketplace for ancillary services. This marketplace will offer the possibility to trade products like reactive power. Such a marketplace, based on a network model, allows the efficient usages of the existing envelopes of generation units to avoid voltage overshoots and to minimize network losses.

In addition to ABB, IBM, SAP, EnBW, Systemplan and the University of Karlsruhe form the MEREGIO project consortium. ABB delivers the necessary network control and interfaces to adjacent systems. Hence, ABB is responsible for the central link between the interconnected physical and commercial processes.

The winning projects were originally announced at the CEBIT 2008 conference.

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.

Peterborough Distribution sold to Hydro One for $105 million.

Peterborough Distribution Inc. Sale to Hydro One delivers a $105 million deal pending Ontario Energy Board approval, a 1% distribution rate cut, five-year rate freeze, job protections, and a new operations centre and fleet facility.

 

Key Points

A $105M acquisition of PDI by Hydro One, with OEB review, rate freeze, job protections, and a new operations centre.

✅ $105 million purchase; Ontario Energy Board approval required

✅ 1% distribution rate cut and a five-year rate freeze

✅ New operations centre; PDI employees offered roles at Hydro One

 

The City of Peterborough said Wednesday it has agreed to sell Peterborough Distribution Inc. to Hydro One for $105 million, amid a period when Hydro One shares fell after leadership changes.

The deal requires approval from the Ontario Energy Board before it can proceed.

According to the city, the deal includes a one per cent distribution rate reduction and a five-year freeze in distribution rates for customers, plus:

  • A second five-year period with distribution rate increases limited to inflation and an earnings sharing mechanism to offset rates in year 11 and onward
  • Protections for PDI employees with employees receiving employment offers to move to Hydro One
  • A sale price of $105 million
  • An agreement to develop a regional operations centre and new fleet maintenance facility in Peterborough

“Hydro One was unique in its ability to offer new investment and job creation in our community through the addition of a new operations centre to serve customers throughout the broader region,” Mayor Daryl Bennett said.

“We’re surrounded by Hydro One territory — in fact, we already have Hydro One customers within the City of Peterborough and new subdivisions will be in Hydro One territory. Hydro One will be able to create efficiencies by better utilizing its existing infrastructure, benefiting customers and supporting growth.”

The sale comes after months of negotiations amid investor concerns about Hydro One’s uncertainties. At one point, it looked like the sale wouldn’t go through, after it was announced that Hydro One had walked away from the bargaining table.

City council approved the sale of PDI in December 2016, despite a strong public opposition and debate over proposals to make hydro public again among some parties.

Elsewhere in Canada, political decisions around utilities have also sparked debate, as seen when Manitoba Hydro faced controversy over policy shifts.

Taiwan's economic minister resigns over widespread power outage

Taiwan Power Blackout disrupts Taipei and commercial hubs after a Taoyuan natural gas plant error, triggering nationwide outage, grid failure, elevator rescues, power rationing, and the economic minister's resignation, as CPC Corporation restores supply.

 

Key Points

A nationwide Taiwan outage from human error at a Taoyuan gas plant, triggering rationing and a minister's resignation.

✅ Human error disrupted natural gas supply at Taoyuan plant

✅ 6.68 million users affected; grid failure across cities

✅ Minister Lee resigned; President Tsai ordered a review

 

Taiwan's economic minister resigned after power was knocked out in many parts of Taiwan, with regional parallels such as China power cuts highlighting grid vulnerabilities, including capital Taipei's business and high-end shopping district, due to an apparent "human error" at a key power plant.

Economic Affairs minister Lee Chih-kung tendered his resignation verbally to Premier Lin Chuan, United Daily News reported, citing a Cabinet spokesman. Lin accepted the resignation, the spokesman said according to the daily.

As many as 6.68 million households and commercial units saw their power supply cut or disrupted on Tuesday after "human error" disrupted natural gas supply at a power plant in northern Taiwan's Taoyuan, the semi-official Central News Agency reported, citing the government-controlled oil company CPC Corporation as saying.

The company added that power at the plant, Taiwan's biggest natural gas power plant, resumed two minutes later.

In New Taipei City, there were at least 27,000 reported cases of people being stuck in lifts. Photos in social media also showed huge crowds stranded in lift lobby in Taipei's iconic 101-storey Taipei 101 building.

Power rationing was implemented beginning 6pm, and, as seen in the National Grid short supply warning in other markets, such steps aim to stabilize supply, Central News Agency said. Power supply was gradually being restored beginning at about 9:40pm. news reports said.

President Tsai Ing-wen apologised for the blackout, noting parallels with Japan's near-blackouts that underscored grid resilience, and said that she has ordered all relevant departments to produce clear report in the shortest time possible.

"Electricity is not just a problem about people's livelihoods but also a national security issue. A comprehensive review must be carried out to find out how the electric power system can be so easily paralysed by human error," said Ms Tsai in a Facebook post.

Taiwan has been at risk of a power shortage after a recent typhoon knocked down a power transmission tower in Hualien county along the eastern coast of Taiwan, rather than a demand-driven slowdown like the China power demand drop during pandemic factory shutdowns. This reduced the electricity supply by 1.3million kilowatts, or about 4 per cent of the operating reserve.

That was followed by the breakdown of a power generator at Taiwan's largest power plant, which further reduced the operating reserve by 1.5 per cent.

The situation is worsened by the ongoing heatwave that has hit Taiwan, with temperatures soaring to 38 degrees Celsius over the past week.

As a result, the government had imposed the rationing of electricity, and, highlighting how regional strains such as China's power woes can ripple into global markets, switched off all air-conditioning in many of its Taipei offices, a move that drew some public backlash.

TC Energy confirms Ontario pumped storage project is advancing

Ontario Pumped Storage advances as Ontario's largest energy storage project, delivering clean electricity, long-duration capacity, and grid reliability for peak demand, led by TC Energy and Saugeen Ojibway Nation, with IESO review underway.

 

Key Points

A long-duration storage project in Meaford storing clean power for peak demand, supporting Ontario's emission-free grid.

✅ Stores clean electricity to power 1M homes for 11 hours

✅ Partnership: TC Energy and Saugeen Ojibway Nation

✅ Pending IESO review and OEB regulation decisions

 

In a bid to accelerate the province's ambitions for clean economic growth, TC Energy Corporation has announced significant progress in the development of the Ontario Pumped Storage Project. The Government of Ontario in Canada has unveiled a plan to address growing energy needs as a sustainable road map aimed at achieving an emission-free electricity sector, and as part of this plan, the Ministry of Energy is set to undertake a final evaluation of the proposed Ontario Pumped Storage Project. A decision is expected to be reached by the end of the year.

Ontario Pumped Storage is a collaborative effort between TC Energy and the Saugeen Ojibway Nation. The project is designed to be Ontario's largest energy storage initiative, capable of storing clean electricity to power one million homes for 11 hours. As the province strives to transition to a cleaner electricity grid by embracing clean power across sectors, long duration storage solutions like Ontario Pumped Storage will play a pivotal role in providing reliable, emission-free power during peak demand periods.

The success of the Project hinges on the approval of TC Energy's board of directors and a fruitful partnership agreement with the Saugeen Ojibway Nation. TC Energy is aiming for a final investment decision in 2024, as Ontario confronts an electricity shortfall in the coming years, with the anticipated in-service date being in the early 2030s, pending regulatory and corporate approvals.

“Ontario Pumped Storage will be a critical component of Ontario’s growing clean economy and will deliver significant benefits and savings to consumers,” said Corey Hessen, Executive Vice-President and President, TC Energy, Power and Energy Solutions. “Ontario continues to attract major investments that will have large power needs — many of which are seeking zero-emission energy before they invest. We are pleased the government is advancing efforts to recognize the significant role that long duration storage plays — firming resources, including new gas plants under provincial consideration, will become increasingly valuable in supporting a future emission-free electricity system.” 

The Municipality of Meaford also expressed its support for the project, recognizing the positive impact it could have on the local economy and the overall electricity system of Ontario. Additionally, various stakeholders, including LiUNA OPDC, LiUNA Local 183, and the Ontario Chamber of Commerce, lauded the potential for job creation, training opportunities, and resilient energy infrastructure as Ontario seeks new wind and solar power to ease a coming electricity supply crunch.

The timeline for Ontario Pumped Storage's progress includes a final analysis by the Independent Electricity System Operator (IESO) to confirm its role in Ontario's electricity system and in balancing demand and emissions during the transition, to be completed by 30 September 2023. Concurrently, the Ministry of Energy will engage in consultations on the potential regulation of the Project via the Ontario Energy Board, while debates over clean, affordable electricity intensify ahead of the Ontario election, with a final determination scheduled for 30 November 2023.

European Power Hits Records as Plants Start to Buckle in Heat

European Power Crisis intensifies as record electricity prices, nuclear output cuts, gas supply strain, heatwave drought, and Rhine shipping bottlenecks hit Germany, France, and Switzerland, tightening winter storage and driving long-term contracts higher.

 

Key Points

A surge in European power prices from heatwaves, nuclear curbs, Rhine coal limits, and reduced Russian gas supply.

✅ Record year-ahead prices in Germany and France

✅ Nuclear output curbed by warm river cooling limits

✅ Rhine low water disrupts coal logistics and generation

 

Benchmark power prices in Europe hit fresh records Friday as utilities are increasingly reducing electricity output in western Europe because of the hot weather. 

Next-year contracts in Germany and France, Europe’s biggest economies rose to new highs after Switzerland’s Axpo Holding AG announced curbs at one of its nuclear plants. Electricite de France SA is also reducing nuclear output because of high river temperatures and cooling water restrictions, while Uniper SE in Germany is struggling to get enough coal up the river Rhine. 

Europe is suffering its worst energy crunch in decades, and losing nuclear power is compounding the strain as gas cuts made by Russia in retaliation for sanctions drive a surge in prices. The extreme heat led to the driest July on record in France and is underscoring the impact that a warming climate is having on vital infrastructure.

Water levels on Germany’s Rhine have fallen so low that the river may effectively close soon, impacting supplies of coal to the plants next to it. The Rhone and Garonne in France and the Aare in Switzerland are all too warm to be used to cool nuclear plants effectively, forcing operators to limit energy output under environmental constraints. 

Northwest European weather forecast for the next two weeks:
relates to European Power Hits Records as Plants Start to Buckle in Heat
  
The German year-ahead contract gained as much as 2% to 413 euros a megawatt-hour on the European Energy Exchange AG. The French equivalent rose 1.9% to a record 535 euros. Long-term prices are coming under pressure because producing less power from nuclear and coal will increase the demand for natural gas, which is badly needed to fill storage sites ahead of the winter.  


France to Curb Nuclear Output as Europe’s Energy Crisis Worsens
Uniper SE said on Thursday that two of its coal-fired stations along the Rhine may need to curb output during the next few weeks as transporting coal along the Rhine becomes impossible. 

Plants on the river near Mannheim and Karlsruhe, operated by Grosskraftwerk Mannheim AG and EnBW AG, have previously struggled to source coal because of the shallow water, even as German renewables deliver more electricity than coal and nuclear at times. Both companies said generation hasn’t been affected yet. 

“The low tide is not currently affecting our generation of energy because our plants do not have the need for continuous fresh water,” a Steag GmbH spokesman said on Friday. “But the low tide level can make running plants and transporting coal more complicated than usual.”

The spokesman said though that there is slight reduction in output of about 10 to 15 megawatts, which would equate to a few percent, because of the hot temperatures. “This has been happening over some time now and is a problem for everyone because the plant system is not designed to withstand such hot temperatures,” he said.

Altmaier's new electricity forecast: the main driver is e-mobility

Germany 2030 Electricity Demand Forecast projects 658 TWh, driven by e-mobility, heat pumps, and green hydrogen. BMWi and BDEW see higher renewables, onshore wind, photovoltaics, and faster grid expansion to meet climate targets.

 

Key Points

A BMWi outlook to 658 TWh by 2030, led by e-mobility, plus demand from heat pumps, green hydrogen, and industry.

✅ Transport adds ~70 TWh; cars take 44 TWh by 2030

✅ Heat pumps add 35 TWh; green hydrogen needs ~20 TWh

✅ BDEW urges 70% renewables and faster grid expansion

 

Gross electricity consumption in Germany will increase from 595 terawatt hours (TWh) in 2018 to 658 TWh in 2030. That is an increase of eleven percent. This emerges from the detailed analysis of the development of electricity demand that the Federal Ministry of Economics (BMWi) published on Tuesday. The main driver of the increase is therefore the transport sector. According to the paper, increased electric mobility in particular contributes 68 TWh to the increase, in line with rising EV power demand trends across markets. Around 44 TWh of this should be for cars, 7 TWh for light commercial vehicles and 17 TWh for heavy trucks. If the electricity consumption for buses and two-wheelers is added, this results in electricity consumption for e-mobility of around 70 TWh.

The number of purely battery-powered vehicles is increasing according to the investigation by the BMWi to 16 million by 2030, reflecting the global electric car market momentum, plus 2.2 million plug-in hybrids. In 2018 there were only around 100,000 electric cars, the associated electricity consumption was an estimated 0.3 TWh, and plug-in mileage in 2021 highlighted the rapid uptake elsewhere. For heat pumps, the researchers predict an increase in demand by 35 TWh to around 42 TWh. They estimate the electricity consumption for the production of around 12.5 TWh of green hydrogen in 2030 to be just under 20 TWh. The demand at battery factories and data centers will increase by 13 TWh compared to 2018 by this point in time. In the data centers, there is no higher consumption due to more efficient hardware despite advancing digitization.

The updated figures are based on ongoing scenario calculations by Prognos, in which the market researchers took into account the goals of the Climate Protection Act for 2030 and the wider European electrification push for decarbonization. In the preliminary estimate presented by Federal Economics Minister Peter Altmaier (CDU) in July, a range of 645 to 665 TWh was determined for gross electricity consumption in 2030. Previously, Altmaier officially said that electricity demand in this country would remain constant for the next ten years. In June, Chancellor Angela Merkel (CDU) called for an expanded forecast that would have to include trends in e-mobility adoption within a decade and the Internet of Things, for example.

Higher electricity demand
The Federal Association of Energy and Water Management (BDEW) is assuming an even higher electricity demand of around 700 TWh in nine years. In any case, a higher share of renewable energies in electricity generation of 70 percent by 2030 is necessary in order to be able to achieve the climate targets and to address electricity price volatility risks. The expansion paths urgently need to be increased and obstacles removed. This could mean around 100 gigawatts (GW) for onshore wind turbines, 11 GW for biomass and at least 150 GW for photovoltaics by 2030. Faster network expansion and renovation will also become even more urgent, as electric cars challenge grids in many regions.
