Smart Savings – College Cuts Its Heating and Electricity Costs

College, Liverpool, England

Like most educational facilities, Wirral Metropolitan College mainly needs energy for heating, hot water and lighting. The college runs two gas-powered cogeneration plants, each with an output of 65 kW. One of the plants supplies heat and electricity around the clock, while the other only runs in winter when demand is higher.

To enable the storage of excess electricity for use later on, the college installed the TS HV 70 from TESVOLT. The system works together with a phase change battery to store surplus energy at times when demand is low and support the heating and electrical systems when it rises again. The new system will pay for itself in just six years, after which it will save the college an estimated EUR 63,000 per year.
