Utilities prepare for Tropical Storm Hanna

E.ON Digital Transformer Stations modernize distribution grids with smart grid monitoring, voltage control, and remote switching, enabling bidirectional power flow, renewables integration, and rapid fault isolation from centralized grid control centres.

Key Points

Remotely monitored grid nodes enhancing smart grid stability and speedier fault response.

✅ Real-time voltage and current data along feeders and laterals

✅ Remote switching cuts outage duration and truck rolls

✅ Supports renewables and bidirectional power flows

E.ON plans to commission 2500 digital transformer stations in the service areas of its four German distribution grid operators - Avacon, Bayernwerk, E.DIS and Hansewerk - by the end of 2019. Starting this year, E.ON will solely install digital transformer stations in Germany, aligning with 2019 grid edge trends seen across the sector. This way, the digital grid is quite naturally being integrated into E.ON's distribution grids.

With these transformer stations as the centrepiece of the smart grid, it is possible to monitor and control using synchrophasors in the power grid from the grid control centre. This helps to maintain a more balanced utilisation of the grid and, with increasing complexity, ensures continued security of supply.

Until now, the current and voltage parameters required for safe grid operation could usually only be determined at the beginning of a power line, where there is usually a grid substation in place. Controlling current flow and voltage in the downstream system was physically impossible.

In the future, grids will have to function in both directions: they will bring electricity to the customer while at the same time collecting and transmitting more and more green electricity via HVDC technology where appropriate. This requires physical data to be made available along the entire route. To ensure security of supply, voltage fluctuations must be kept within narrowly defined limits and the current flow must not exceed the specified value, while reducing line losses with superconducting cables remains an important consideration. To manage this challenge, it is necessary to install digital technology.

The possibility of remotely controlling grids also reduces downtimes in the event of faults and supports a smarter electricity infrastructure approach. With the new technology, our grid operators can quickly and easily access the stations of the affected line. The grid control centres can thus limit and eliminate faults on individual line sections within a very short space of time.

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.

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.

Ontario Electricity COVID-19 Recovery Rate sets a fixed price of 12.8 cents/kWh, replacing time-of-use billing and aligning costs across off-peak, mid-peak, and on-peak periods per Ontario Energy Board guidance through Oct. 31.

Key Points

A flat 12.8 cents/kWh electricity price in Ontario that temporarily replaces time-of-use rates from June 1 to Oct. 31.

✅ Fixed 12.8 cents/kWh, all hours, June 1 to Oct. 31

✅ Higher than off-peak 10.1, lower than mid/on-peak

✅ Based on Ontario Energy Board average cost

Ontario residents will now have to pay a fixed electricity price that is higher than the off-peak hydro rate many in the province have been allowed to pay so far due to the pandemic. 

The announcement, which was made in a news release on Saturday, comes after the Ontario government suspended the normal “time-of-use” billing system on March 24 and as electricity rates are about to change across Ontario. 

The government moved all customers onto the lowest winter rate in response to the pandemic as emergency measures meant more people would be at home during the middle of the day when electricity costs are the highest. 

Now, the government has introduced a new “COVID-19 recovery rate” of 12.8 cents per kilowatt hour at all times of the day. The fixed price will be in place from June 1 to Oct. 31. 

The fixed price is higher than the winter off-peak price, which stood at 10.1 per kilowatt hour. However, it is lower than the mid-peak rate of 14.4 per kilowatt hour and the high-peak rate of 20.8 per kilowatt hour, even though typical bills may rise as fixed pricing ends for many households. 

“Since March 24, 2020, we have invested just over $175 million to deliver emergency rate relief to residential, farm and small business electricity consumers by suspending time-of-use electricity pricing,” Greg Rickford, the minister of energy, northern development and mines, said in a news release. 

“This investment was made to protect the people of Ontario from a marked increase in electricity rates as they did their part by staying home to prevent the further spread of the virus.”

Rickford said that the COVID-19 recovery rate is based on the average cost of electricity set by the Ontario Energy Board. 

“This fixed rate will continue to suspend time-of-use prices in a fiscally responsible manner,” he said. "Consumers will have greater flexibility to use electricity when they need it without paying on-peak and mid-peak prices, and some may benefit from ultra-low electricity rates under new time-of-use options."
