UK grid operator highlights challenges in low-carbon energy transition

Britain's new state-owned grid operator, the National Energy System Operator (NESO), has highlighted significant challenges in the country's shift to a low-carbon energy system. A report released today emphasizes the need for substantial investments in transmission and changes in energy demand patterns. To meet government targets, Britain must rapidly increase its renewable energy capacity. The NESO states that upcoming renewable energy auctions must approve more offshore capacity than in the last six combined, aiming for 28 to 35 gigawatts by 2030. Onshore wind and solar power capacities also need to double and triple, respectively. Despite the expansion of wind and solar energy, the UK will retain gas-fired power plants as backup. Currently, gas accounts for about a third of the energy mix but is expected to drop to 5% by 2030. The NESO reports that maintaining the energy system will not cost more in 2030 than it does now.
