CISCO has shaped the future of the internet by creating unprecedented value and opportunity for their customers, employees, investors and ecosystem partners and has become the worldwide leader in networking - transforming how people connect, communicate and collaborate. The company required addition electrical resilience against the national grid supply. As a global player, a reduction in carbon emissions was also important to them. ENER-G was chosen to provide them with their optimum solution.
The system comprises a highly efficient gas fired trigeneration system powered by a 425kWe cogeneration unit that creates electricity and chilled water for the cooling load for the server equipment. This system is unique in the fact that it carries a no break provision, to guarantee no interruption in performance as just an hour without power would cost the business millions.
The trigeneration system will help reduce energy costs and stabilise them over time, it also sits well with the company’s green energy policy.
This new system is displacing an electric screw compressor chiller which currently uses grid electricity to provide the chilled water. The electric chiller is carbon intense so the new efficient trigeneration system will reduce the carbon impact.
The project was financed by capital purchase with a specialised operation and maintenance contract between ENER-G and CISCO.
