City of London selects EMMA AI for multi-site energy management rollout

Effective multi-site energy management starts with clear, reliable data.

Optimal Monitoring has secured a new partnership with the City of London following a successful three-month pilot of its EMMA AI energy management platform, committing to a wider rollout across a portfolio of some of central London’s most iconic and complex buildings.

After validating performance during the pilot phase, the wider deployment will introduce:

• Sub-metering for greater granularity

• Heat monitoring

• Integrated gas and electricity tracking

• Automated data capture and reporting

• Actionable insights to reduce waste faster

By combining richer data with continuous monitoring, the City expects to identify inefficiencies quickly and target improvements with confidence.

The goal is clear: save hundreds of thousands of pounds while reducing carbon emissions across the estate.

This rollout demonstrates how large, multi-site organisations can move beyond manual reporting and fragmented systems towards a smarter, automated approach to energy management.

From pilot to proof to scale

The initial pilot provided detailed evidence of where energy was being wasted and where operational changes could deliver immediate savings.

With proven results, the City has committed to scaling the platform across more locations throughout the year.

For Optimal Monitoring, the project reinforces growing demand from complex estates that need:

• Clear, reliable energy data

• Faster decision-making

• Measurable ROI

• Reduced operational overhead

Looking ahead

Deployment begins immediately, with further integrations planned over the coming months.

As more sites come online, the City of London will benefit from a unified view of performance, enabling teams to prioritise action and deliver long-term efficiency improvements.
