Why the energy trilemma is not a zero-sum trade-off

Following his appearance at International Energy Week earlier this year, Fintan Slye FEI, CEO of the National Energy System Operator (NESO), sets out his perspective on the challenges facing Great Britain’s energy system, and how to strike the right balance across the energy trilemma for consumers.

Cleanest-ever electricity recorded in the UK

The UK’s electricity was the cleanest ever in 2024, according to a new study from Carbon Brief, with CO₂ emissions per unit falling by more than two-thirds in a decade. The phasing out of coal means the country is now getting less than half as much electricity from burning fossil fuels as a decade ago. Over the same period, renewable generation has more than doubled.

Securing the UK’s long-term energy future with nuclear

While the focus on 2030 clean power targets for the UK is important, we must also consider what happens beyond that – intergenerational equality demands it, according to Dr Philip Rogers, Director of nuclear consultancy and project developer Equilibrion.

Global energy investment is set to rise to $3.3tn in 2025 amid economic uncertainty and energy security concerns

A surge in global energy investment (clean technologies + oil and gas) to a record $3.3tn in 2025 is forecast by the International Energy Agency (IEA), with clean energy expected to command double the capital of fossil fuels. But a new KPMG survey suggests that investor appetite is being tempered by policy uncertainty and tech risks.

The urgent need to expand the UK’s energy grid for net zero

Building a grid able to distribute net zero electricity in the UK by 2030 is possible, but will require enormous cooperation by the relevant stakeholders, argues Joanna Carter, Head of Electricity Connections at EDF Renewables.

Zonal pricing for the GB electricity market, or fix transmission infrastructure first?

The introduction of zonal electricity pricing should come after the transmission grid has been upgraded to deal with a future zero carbon electricity system, argue Will Blyth, from Oxford Energy Associates and Callum MacIver, from Strathclyde University; both also work at the UK Energy Research Centre (UKERC).

How to build a bigger BESS

Long-duration energy storage (LDES) is increasingly seen as vital to a resilient power grid, and the UK should soon have a lot more of it. Ofgem defines LDES as ‘systems that can store and release electricity for eight hours or more’. Although most battery installations are used for short-term storage (less than four hours), some innovative suppliers, including Field, are using batteries for LDES. Toby Clark explains how.

More can be done to help energy consumers through this crisis

With the Energy Institute’s (EI) Energy Barometer member survey focused on the UK’s response to the energy crisis, EI Trustee and UK Energy Research Centre (UKERC) Director Professor Rob Gross FEI examines three options that could yet be put in place to start reducing consumer bills before this winter.

Spanish blackouts won’t happen in the UK, says grid operator

The UK is well-shielded from an Iberian-style power blackout, according to a new National Energy System Operator (NESO) report, which emphasises the robust measures already in place while urging further progress in voltage management and system modelling. Meanwhile, new government statistics reveal a record 73.8% of UK electricity came from clean power in 2024, highlighting increased momentum towards the government’s clean power by 2030 target.

Wind power first for Britain

Britain’s growing fleet of wind turbines generated more electricity than gas-fired power stations for the first time in the first three months of this year. Meanwhile, two North Sea offshore wind developers are planning to kickstart a route to net zero North Sea oil and gas production, and the UK government has unveiled a proposal to create a ‘treasure map’ showing the potential for North Sea carbon, capture and storage (CCS) projects.
