Britain’s National Energy System Operator has delayed the release of the Strategic Spatial Energy Plan (SSEP) by “several months” in order to incorporate the release of new energy generation cost data.
Director of Strategic Energy Planning & Chief Engineer at NESO Julian Leslie (pictured) wrote in a letter to industry stakeholders: “NESO and DESNZ have taken the decision to re-run the SSEP modelling using this refreshed data to ensure our analysis and recommendations are based on the most credible and current information.”
The new information released by DESNZ will be publicly accessible, and will allow “stakeholders, consumers, and investors to see and understand key inputs shaping national energy planning”, Leslie wrote.
The new data will also inform the delivery of the Centralised Strategic Network Plan (CSNP) and accompanying Regional Energy Strategic Plans (RESP).
“While this will mean the timeline to develop the SSEP will extend by several more months, we believe it is the right thing to do to strengthen the quality and resilience of the plan.”
