In 2000 with their heating boilers at the end of their operational life and not able to meet the future energy demands of the hospital, the Trust looked for ways of replacing them and delivering stable utility supplies for the site. To meet both hospitals needs for heating, electricity and standby generation Dalkia designed a CHP based energy solution capable of delivering the stable supplies and installing the new plant without interrupting the work of the hospital.
Included in this first phase was a 2 MWe base load generation capacity from a combined heat and power plant with an additional 4MWe of standby capacity. Under the scheme, steam is generated by a waste heat boiler, two 11,400kg per hour boilers, and three existing boilers.
In 2011 the expansion of the site created a demand for more energy and a new 15 year contract provided a further £2.5million upgrade which included a 2MWE CHP from Dalkia’s specialist CHP division Cogenco, and a combination waste heat/fired boiler to deliver heating, hot water and electricity.
