Ofgem has confirmed its intention to expose distributed generators with a capacity of less than 100MW to wider transmission network charges. The regulator announced the change as part of the minded-to decision for its significant code review looking at forward-looking charges and grid access arrangements.

National Grid Electricity System Operator (ESO) and Scottish and Southern Electricity Networks (SSEN) have launched a new study looking at how customers respond to price signals when using electric vehicles, heat pumps and batteries. The research will analyse historical data from more than 25,000 households on Octopus Energy’s smart time-of-use tariff, making it the UK’s largest ever study into domestic flexibility.

To achieve their ambitious decarbonisation targets, local authorities must get to grips with a complex and evolving energy system. But, as UK100 chief executive Polly Billington argues, the energy sector must also do its part in seeking to understand the needs and the capabilities of local government. She talks to Lucinda Dann about how the sector is doing so far and why local area energy planning must happen with councils, rather than to them.
Interviews
Business and energy secretary Kwasi Kwarteng has said networks’ response to storm must improve, describing power cuts of longer than three days as “unacceptable.” Appearing before the House of Commons Scottish Affairs Committee to answer questions about November’s Storm Arwen, which left some households without power for more than a week, the minister also rejected a suggestion that networks’ resilience to such events should have been stress tested by Ofgem.

The Energy Networks Associations has set out its plans for its Open Networks project in 2022, which will continue to focus on heavily standardising and coordinating flexibility services. The ENA said the industry initiative, which was launched in 2017 to accelerate the transition to a smart, flexible energy system, has enabled the UK to establish “world leading” local flexibility markets, with contracts for more than 3GW of flexibility being made available for tender in Great Britain last year.

Ofgem is considering introducing independent distribution system operators (IDSOs) as a way of meeting the needs of the future energy system. The proposal is one of four solutions the regulator is currently considering as part of its review into local energy system operation.
News
UK Power Networks has announced it is launching a £13 million flexibility tender for 292MW of power at 113 different sites across its region. The tender, hosted on the network operator’s Piclo Flex platform, includes locations with early start dates up to four weeks after arrangements are made.
News
Western Power Distribution (WPD) has revealed it is undertaking a collaborative project with South West Water to explore how its pumping processes can be used to provide flexibility to the power grid.  The FLOWERS project will look at how energy efficiencies and flexibility options can provide mutual benefits to the networks and customers of both businesses.
News
National Grid Electricity System Operator (ESO) has awarded £323 million to grid stability projects in Scotland, including to what is thought to be the first use of grid forming converters across a large scale. ESO’s stability pathfinder project is trialling a new grid stability service incorporating inertia, reactive power and short circuit level (SCL) - the amount of current that flows on the system during a fault.
News
Ofgem has said networks should consider sharing contact centre staff during times of crisis as part of its interim report on their responses to Storm Arwen. The regulator made the recommendation after finding that more than four in ten calls to Northern Powergrid's contact centre were abandoned by customers between the arrival of the storm on the 26 November and the following Saturday (3 December).
News
Given its perceived role in unlocking the true potential of the UK’s energy system as it transitions to net zero, the conversation around the Future System Operator no longer centres on if, but when and how. Utility Week gauged the views of smart grid and system operation leads across the energy sector on the roles and responsibilities of the new body and how a functional FSO can be achieved as quickly as possible.
