INTERMITTENT RENEWABLE ENERGIES

Several constraints exist with intemittent renewable energies: Difficulty to predict long term production

opportunities Inequal daily production Lack of control over production and legal

obligation to purchase

Impact on the power system: Fragile supply and demand balance Risks due to high dependency on climate

conditions High potential impact on the network’s

electricity frequency

EFFECTS ARE INCREASED ON ISOLATED NON INTERCONNECTED POWER SYSTEMS

Type : Lithium-Ion Battery

Power : 5 MW

Maximum autonomy: 30 minutes

Reaction time : 500 millisecond

THE CENTRAL BATTERY SYSTEM

5MW CENTRAL BATTERYINNOVATION 1st central battery system in Martinique Self-operated and stationary storage

system

INCREASED NETWORK STABILITY Power is available on the network

anytime Allows an increase in the potential of

intermittent energy installed on the network.

Facilitator of energy transition

BENEFITS Profitable technology High savings in production costs Decreasing battery prices Reduced CO2 emissions

PREPARING THE ENERGY TRANSITION

EDF is committed, with major organizations of the territory, to reduce the energy consumption by 10% by 2020. The innovative projects implemented will reduce the carbon footprint by avoiding the emission of 20,000 tonnes of CO2 per year.
