Low carbon energy efficiency, demand side response measures implemented at Stevenage’s Lister Hospital in conjunction with KiWi Power, a ‘smart grid’ and energy demand management specialist, are expected to generate over £100,000 annually in new revenue.

Managed by the East and North Hertfordshire NHS Trust, Lister Hospital recently upgraded its high voltage electricity network. During KiWi Power’s turnkey project, four new diesel generators were installed for back-up power, alongside a duplicate power feed from UK Power Networks. KiWi Power has also installed smart controls to allow new gas CHP plant to run in parallel with standby power equipment, enabling additional utility bill savings via reduced peak time energy consumption. Surplus power generated can be exported back to the grid, providing ‘a new, risk-free, revenue stream’. The hospital will receive payments through demand response aggregator KiWi Power via National Grid. Control systems were integrated with the hospital’s existing SCADA equipment, so KiWi Power can control the standby power equipment remotely from its smart grid operations centre in London.
