Lincolnshire Partnership NHS Foundation Trust × Emma AI
AI-enabled energy monitoring across a complex healthcare estate
“Emma has greatly improved the viability of energy use across the trust and as a result we are now investing in further metering to make additional savings”
Overview
Healthcare estates are among the most complex environments in which to manage energy effectively. Hospitals and clinical facilities operate continuously, with specialist equipment, ventilation systems and strict environmental requirements creating significant and often unpredictable energy demand.
Lincolnshire Partnership NHS Foundation Trust partnered with Optimal Monitoring to deploy the Emma AI energy management platform across multiple sites, supporting cost reduction and carbon goals.
Why Emma AI?
Emma AI analyses available energy data and identifies saving opportunities. Where suitable existing data is available, no new monitoring hardware is needed.
Initial data analysis
Emma AI analysed billing and BMS data, revealing avoidable spend from overnight cooling, late lighting and misconfigured timer settings.
Implementation pilot
The phased deployment at Grantham, Boston and Lincoln integrated existing fiscal energy meters, helping the team investigate financial and carbon-saving opportunities.
Roll-out to the wider estate
The case study sets out investment in additional meters and plans to integrate water, solar and heat data for greater visibility across the estate.
What this delivered
- Rapid ROI — reported in under three months.
- Reporting support — automated data collection to support reporting and planning.
- Actionable insights — clearer recommendations to help tackle energy waste.
- Automated analysis — across the monitored scope.
What the pilot proved
- AI-enabled energy monitoring demonstrated value across a complex healthcare estate.
- Emma AI highlighted inefficiencies and unusual consumption patterns that would previously have been difficult to detect.
- The project supported a move from reactive energy management towards a more proactive, data-led approach.
Summary
With Emma AI deployed across the initial sites, the estates team demonstrated the value of AI-enabled monitoring in a complex healthcare setting.
Early findings supported an initial savings target of around £30,000 per year, with an opportunity to scale towards £200,000 per year as further metering and monitoring are added.
Looking ahead
Plans include extending Emma AI to additional facilities, integrating water and heat data, incorporating on-site solar generation and automating energy reporting.
