Hydroelectric power plants

Salisano hydroelectric power plant

Province: Rieti
Installed Power: 24.6 MW

The cutting-edge technology at the Salisano power plant is our pride and joy.

The water and hydroelectric part of the plant is built "in a cave" by constructing tunnels within the calcareous spur. How does the hydroelectric power plant work? The in-stream plant is one of few in Europe and the world to produce energy by exploiting drinking water from the Peschiera-Capore aqueduct system. The incoming water going towards Rome converges here and mixes before flowing into the two branches of the Peschiera aqueduct system, which supplies the Capital.

Marconi di Orte hydroelectric power plant

Acea hydroelectric power plants include the Marconi hydroelectric power plant in Orte

Province: Viterbo
Installed Power: 20 MW

This in-stream, hydroelectric, power plant stands on the final stretch of the River Nera, a few kilometres from the confluence with the River Tiber. In addition to the production power plant, it also includes the San Liberato dam and the by-pass channel.

Cecchina hydroelectric power plant

Province: Rome
Installed Power: 0.4 MW

The system installed inside the Cecchina Water Power Plant is owned, automated and remotely managed on a daily basis by Acea Ato 2, which receives the alarm / fault signals and sends them to the Control Room at the Tor di Valle Power Plant for an onsite call out.

Madonna del Rosario hydroelectric power plant

Province: Rome
Installed Power: 0.4 MW

The system is installed inside the Madonna del Rosario Water Power Plant owned by Acea Ato 2. The plant converts the water's mechanical energy into electricity and tours can be arranged for visitors subject to notifying their presence onsite to the Acea SpA Water Operational Room and Safety Room, who will authorise entry.

Volta di Castel Madama hydroelectric power plant

Province: Rome
Installed Power: 9.4 MW

The plant is located in the municipality of Castel Madama and includes the San Cosimato dam in the gorge excavated out of the River Aniene. The right bank consists of an approximately 50 metre high rock wall (Rupe di S. Cosimato) displaying numerous cavities and overhanging masses. This wall extends for a stretch of approximately 200 metres upstream and downstream of the dam. The left bank has a steep, wooded slope, scarred by various valleys cutting into it and affected by numerous phenomena of instability. The structure foundations lie on calcareous rock at a depth of approximately 1.5 metres below the river bed downstream.
