RUH Bath generates revenue from its on-site diesel backup generators by providing occasional reserve energy for National Grid. RUH Bath also saves money by reducing consumption during winter peaks. Find out more in the case study below. 

Royal United Hospital Bath | Demand Response

Occupying a 52-acre site, the Royal United Hospital Bath (RUH Bath) provides acute treatment and care for an estimated catchment population of 500,000 people.

In 2012, RUH Bath NHS Foundation Trust engaged Flexitricity to utilise two 800kW standby diesel generators to create revenue through the provision of demand-side response. The standby generation capacity was integrated into our 24-hour operational system, and now provides Short-Term Operating Reserve (STOR) and triad management.

Through Flexitricity, RUH Bath generates revenue from its on-site diesel backup generators by providing occasional reserve energy for National Grid. RUH Bath also saves money by reducing consumption during winter peaks.

Flexitricity delivers reserve energy to National Grid using a fully-automated control and monitoring system. The generators at RUH Bath are operated remotely in response to national or regional needs, while ensuring that the hospital’s core requirement for standby power is always met. This fully-managed service optimises revenue using a tailored control approach and intelligent arbitraging between services. Flexitricity pays RUH Bath for making its capacity available during agreed periods. Further payments are made for power delivery during demand-response events.

Triad management at RUH Bath is complementary to its STOR participation. During the November to February triad season, Flexitricity remotely starts generation during likely triad periods. This lowers site consumption and reduces the triad charges on the site’s electricity bills.
