The La Rance Tidal Power Station is the world's first tidal power station and also the world's second biggest tidal power station. The facility is located on the estuary of the Rance River, in Brittany, France. Opened on the 26th November 1966, it is currently operated by EDF, and is the second largest tidal power station in the world, in terms of installed capacity. With a peak rating of 240 MW, generated by its 24 turbines, it supplies 0.012% of the power demand of France. With a capacity factor of approximately 40%, it supplies an average 96 MW, giving an annual output of approximately 600 GWh. The barrage is 750m (2,461ft) long, from Brebis point in the west to Briantais point in the east. The power plant portion of the dam is 332.5m (1,091ft) long. Power is generated from 24 bulb turbines with a 5.35m (17.55ft) diameter that rotates at 93.75rpm and is rated at 10MW at a head of 5.65m (18.54ft).

The barrage has caused progressive silting of the Rance ecosystem. Sand-eels and plaice have disappeared, though sea bass and cuttlefish have returned to the river. By definition, tides still flow in the estuary and the operators, EDF endeavors to adjust their level to minimize the biological impact.
The Rance Basin has undergone a full scale evaluation of the ecological impact of the tidal power station during 20 years of operation. Significant impact during the 3-year construction phases and closing of the estuary provoked disappearance of marine flora & fauna due to salinity fluctuations, heavy sedimentation and accumulation of organic matter in the basin. The new ecological equilibrium, established in the space of 10 years remains fragile and being linked to the degree of stability of abiotic conditions, dependent to a large extent on the operation conditions of the power stations. By 1976, the Rance estuary was considered again as richly diversified: a new biological equilibrium was reached and aquatic life was flourishing again.
