Reward users with a reduced VAT of 5.5% on the price per kWh
Implement a custom high-temperature heat pump to boost production of geothermal heat by 50% and recover 4.4 MW, therefore increasing production from 54,000 to 81,000 MWh per year.
Expand the heat recovery system of the incineration plant, which accounts for 32% of recovered energy and limits reliance on gas power plants. The share of renewable energy powering the Créteil network is 52%; 20% of which is geothermal heat and 32% recovered heat from the incineration of household waste.
