Lincolnshire Partnership NHS Foundation Trust x EMMA AI
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 NHS 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 provides real-time insight and identifies energy-saving opportunities with no capex, making it a strong fit for NHS Trusts.
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 UK rollout at Grantham, Boston and Lincoln integrated existing fiscal energy meters, proving strong financial and carbon savings.
Roll-out to full estate
Lincoln are currently investing in additional meters and integration of water, solar and heat data to obtain full visibility of the estate.
What this delivered
Rapid ROI – achieved in under three months, proving immediate value.
ESOS compliance – automated data collection to support reporting and planning.
Actionable insights – clear, real-time recommendations driving cost and carbon savings.
100% automated – fully automated energy analysis across the monitored scope.
What the pilot proved
✓
AI-enabled energy monitoring has demonstrated value across a complex healthcare estate.
✓
Emma AI highlights inefficiencies and unusual consumption patterns that would previously have been difficult to detect.
✓
The Trust is moving from reactive energy management to a more proactive, data-driven approach.
Summary
With Emma AI now deployed across the initial Lincolnshire NHS Trust sites, the estates team has already demonstrated the value of AI-enabled energy monitoring across a complex healthcare estate. Early findings support an initial savings target of around £30,000 per year, with a clear opportunity to scale this to £200,000 per year as further metering and monitoring is added across the estate.
Looking ahead
Lincolnshire NHS Trust plans to extend Emma AI monitoring to additional facilities. Future developments include integrating water and heat consumption data, incorporating on-site generation such as solar, and automating energy reporting.
