This document discusses integrated energy planning between SP Energy Networks (SPEN), a distribution network operator, and city councils. It describes how SPEN and cities can work together by sharing development and infrastructure plans to create integrated energy plans. This allows SPEN to better plan infrastructure investments based on city development priorities, and cities benefit from improved energy network support. As an example, the document outlines how SPEN and Glasgow City Council have collaborated on sharing data on load forecasts and development projects to coordinate utility upgrades to support the city's growth.
