Lincolnshire Partnership NHS Foundation Trust: AI-enabled energy monitoring across a complex healthcare estate

  • Sector: Healthcare (NHS)
  • Client: Lincolnshire NHS Trust – Multiple healthcare facilities across Lincoln, Boston and Grantham
  • Challenge: Improve visibility of energy consumption across a complex healthcare estate, reduce energy costs and carbon emissions, support behavioural change, and enhance the digital maturity of energy management and reporting.
  • Solution: Deployed EMMA AI across the Trust’s initial estates, integrating existing fiscal electricity meters with Optimal Monitoring’s wireless sub-metering solutions. The platform automatically analyses energy consumption data, identifies inefficiencies and anomalies, and provides actionable insights to estates teams without the need for manual data analysis.
  • Impact: Established a data-driven approach to energy management across the estate, identifying opportunities to achieve an initial £30,000 annual saving target, rising to over £200,000 as monitoring expands. The success of the deployment led to EMMA AI being extended to additional Trust facilities, supporting operational efficiency, carbon reduction objectives, and long-term digital transformation of the estates function.

Lincolnshire Partnership NHS Foundation Trust worked with Optimal Monitoring to deploy EMMA AI across multiple healthcare sites.

By analysing more than 90 meters, the platform identified avoidable energy waste including overnight cooling, late lighting and timer issues.

The project delivered ROI in under three months and revealed an initial annual savings opportunity of around £30,000, with potential to increase this to £200,000 as further metering is installed.

The Trust is now expanding monitoring and integrating additional data sources such as water, heat and solar.

  • 90+ meters analysed
  • ROI achieved in under 3 months
  • Up to £200k target annual savings
  • 100% automated monitoring
