ESOS audit identifies £4 million in cost savings.

As a major food and drink manufacturer operating 12-hour shifts seven days a week, energy consumption makes up one of the client’s largest operational costs. Needing to comply with the Energy Savings Opportunity Scheme (ESOS), we guided compliance with Phase 3, and uncovered significant opportunities to reduce consumption and cut costs at the same time.

What you need to know

The client’s energy consumption had increased since ESOS Phase 2, due to a change in operating hours. It meant that electricity consumption had soared by 138%, while gas consumption had risen by 28%.

Phase 3 introduced a new requirement: the completion of an Annual Review. This means every organisation must produce a three-year energy efficiency strategy and report on progress annually. We supported the client through this expanded compliance process.

This made it easier for the team to focus on quick wins first to release immediate savings to reinvest in future improvements.

What difference it made

Our survey revealed that the manufacturer could reduce total energy use by 5.2%.

Some of the estimated savings:

Energy management practices 

• Energy savings 588,210 kwh

• Cost savings £137,288

Control improvements 

• Energy savings 1,384,394 kWh

• Cost savings £49,100

LED lighting upgrade 

• Energy savings of 2,931,736 kWh

• Cost savings £670,888

• Carbon savings 566.9 tCO2e

This story shows that energy intensive users have a significant opportunity to not only meet regulations, but to go beyond compliance and achieve real impact. In this example, our unique audit services uncovered savings of 5% and return on investment in just two years.
