This workflow automates energy portfolio governance for energy managers, sustainability teams, and policy compliance officers. It eliminates the manual effort of aggregating multi-source energy data, applying forecasting and optimisation logic, and distributing performance outcomes to stakeholders. Three scheduled API feeds, weather data, energy demand, and renewable generation, are combined into a unified dataset. The Energy Governance Agent, backed by shared memory and a governance model, coordinates three specialist agents: a Renewable Forecasting Agent (predictive generation modelling), a Weather Analysis Agent (climate-adjusted demand assessment), and a Policy Compliance Agent (regulatory alignment checking). Five tools support the orchestration: an Energy Calculator, Optimisation Algorithm Tool, External Data API Tool, Sustainability Research Tool, and Structured KPI Output parser. Results are distributed across three outputs, a Slack sustainability alert, a Gmail performance dashboard email, and a Google Sheets KPI store, giving stakeholders immediate, channel-appropriate visibility into energy governance outcomes.
