Taking on other installers’ work is not something Calibrate do lightly as it can be fraught with problems, but given the context and market demand for bringing perfectly serviceable systems like Timmis’ back on track, Calibrate have devised a business model for optimising systems using a mix of data analytics and engineering re-works. Calibrate plugged in the innovative software and could show in real time, what some simple changes would make to the farm’s bottom line. From the data gathered from the controller, the team set about designing a series of improvements to transform performance.
The heat pump’s co-efficiency of performance sat at just 2.0 with Ofgem’s lowest requirement being 2.9. Not only was the system under-performing, but it was also putting the farm’s substantial RHI tariff rebate in jeopardy. As a result of the control software addressing system inefficiencies and parasitic loads caused by unnecessary plant running times, the COP quickly increased to 3.0 finally taking it beyond Ofgem standard.
The next big step-change occurred when Calibrate carried out pipe re-works to the heating loop. The outcome was a COP jump to over 4.0, a 100% improvement on its original state.
Following assessment through Calibrate Analytics© and optimisation through system re-engineering, the next step that Timmis and other businesses can then consider after a software upgrade is Calibrate’s Gridflex service. This is where the controller acts as an energy aggregator, adjusting electricity use at peak times and selling excess energy back to the National Grid.
Gridflex fully manages this behaviour, providing clients with a totally hands-free passive income running in parallel to business as usual.
