Saint-Jean de Maurienne

Use Case description

INNED distributes over 140 GWh of electricity every year, with peak demand of 42 MW (peak power period). 31% of the total annual electricity is produced by renewables, namely PVs and small hydro plants, with the aim to reach 60% in 2020 and 100% in 2030. Currently there is no storage installed at the INNED network, however there are plans to feed the gas grid (still in St-Jean) with methane using Power to Gas conversion and storage technologies. This grid is operated by GRDF, the national gas distribution company and fed by RTgas, the national transport gas company. GRDF is interested in buying methane produced by SOREA and initial discussions on the project will start within 2017. INNED also plans to produce hydrogen from electrolysis, particularly to use low cost electricity at high production time of hydro power plants. The aim is to use hydrogen as energy storage and produce electricity in a fuel cell (FC), or to feed the gas grid with up to 6 vol% H2.
Following the future strategy of INNED to operate a fully decarbonized grid in 2030, the main aim of the pilot activities in the French pilot site spins around the integration of increasing volumes of distributed renewables into the distribution grid without threating its stability and reliability. To this end the pilot activities will focus on the introduction of novel technologies and business models for Human-Centric Demand Response (DR) in Buildings (control of Heating, Ventilation & Air Condition and lighting loads without compromising building occupants’ comfort and health) and Virtual Energy storage (through the application of Power-to-Heat solutions).
