Green Light for Smart Renewable Heating Scheme in Oxford

A pioneering smart renewable heating scheme in Oxford, part of the £41m Energy Superhub Oxford project, has been given the green light to proceed following lockdown disruption, providing a confidence boost for the construction and renewables industries as they rise to covid-19 operational challenges, and a positive step towards the UK defining how it will meet its 2050 net zero target. The recommencement of the scheme with leading housing provider, Stonewater, and Kensa Contracting, will contribute to the Energy Superhub Oxford (ESO) project’s anticipated savings of 10,000 tonnes of carbon dioxide emissions a year by 2021; the equivalent of taking 2,000 cars off the road.The 60-homes in Blackbird Leys will demonstrate how decarbonisation of heating using ground source heat pumps can interact with local energy systems to allow millions of homes to cut carbon and costs, and adopt a ‘smart cities’ model. The trial represents 20% of homes committed to receiving smart heating with Kensa ground source heat pumps as part of ESO, a world-first project backed by UKRI which is pioneering a model for the rapid decarbonisation of power, transport and heat in cities across the UK and globally. ESO showcases rapid electric vehicle charging, hybrid battery energy storage systems, low carbon heating, and smart energy management to improve air quality and accelerate Oxford’s journey to zero carbon.The residents at Blackbird Leys will have their night storage heating system replaced with a Kensa Shoebox ground source heat pump system coupled with Switchee heating controls, which will constantly sense, learn and respond to the inhabitant’s behaviour. Adding a further smart technology dimension to the running of the heat pump, Kensa’s heat optimisation software will take a day-ahead forecast of half hourly electricity costs, and automatically shift the operating times to enable the occupants to make savings from dynamic tariffs without having to change their behaviour.The smart heating system at Blackbird Leys is expected to save residents 3,520 tonnes of CO2 over their lifetime and cut their current night storage heating bills to levels lower than that of mains gas, all without adding strain to the UK’s electricity grid; a triple-challenge the renewables industry must overcome to ensure low carbon ground source heat pump technology is more widely adopted by society.
