The CEOG (Centrale Électrique de l'Ouest Guyanais) project in French Guiana has a new equity partner in Meridiam, a long-term investor whose Transition Fund is dedicated to infrastructure projects related to energy transition.

This operation is accelerating the development of the project, which is scheduled to be commissioned in 2020 to produce stable, non-polluting electricity for the benefit of the inhabitants of western French Guiana.

The power plant will provide stable electricity day and night to over 10,000 households in French Guiana through its massive hydrogen-based renewable energy storage system.

Meridiam is acquiring 60% of CEOG alongside HDF Energy to finance and develop the project. This will strengthen Meridam’s portfolio of renewable energy projects as the investor, developer and long-term management of infrastructure projects is currently managing 6.2 billion euros in assets.

The inventor of the CEOG – dubbed Renewstable power plant – HDF Energy is an international producer of stable electricity from intermittent energy sources.

The plant combines a 55MW photovoltaic solar farm with the world's largest 140MWh hydrogen-based renewable energy storage capacity, coupled with battery backup storage. This combination allows stable electricity to be produced over the long term with 100% clean energy.

CEOG capacity and location

The CEOG plant will be located in the town of Mana. Connected to the EDF station in Saint-Laurent-du-Maroni, it will produce a fixed daily electrical output of 10MW during the day (8am to 8pm) and 3MW at night (8pm to 8am) over a 20 year period.

With stable and guaranteed power generation, the CEOG plant's service will be equivalent to that provided by diesel or gas-fired power plants, but without the downside of pollution or fuel supply logistics.

CEOG's electricity price will be lower than the current production cost in western French Guiana, and without being subsidised.

Construction is scheduled to begin in Q4 2019 and the plant should be in operation in 2020. CEOG will create around 100 jobs during construction and around 30 permanent, non-relocatable jobs over the 20 years of operation of the plant. Read more: Hydrogen – the “missing link” in energy transition
