COST BENEFIT ANALYSIS OF ENERGY BOXES DEPLOYMENT IN HOUSEHOLDS IN EUROPE: IMPACT OF THE SPOT PRICES
Should domestic end-user retrofit their electric heating thermostat by a market-connected energy box?
Smart-Thermostats are one of the #IOTs best-sellers in 2015. Meantime, the deregulation ofpower markets and the European directive on Hourly Metering are pushing Utilities to launch RealTime Price tariff (RTP) initiatives. The research question is so simple: is there a business interestfor European domestic end-users to go even further and invest in a weather forecast & market-connected energy box to benefit of a RTP tariff to reduce their electric heating bill.
