Costs of hydroelectric systems can vary depending on the location and amount of electricity that can be potentially generated. A 5kw system, which is ideal for the average home, might cost between £20,000 and £25,000, including installation.
The savings you make on bills vary depending on the water energy system in place before. These savings could be substantial if you’re currently using electricity from the Grid.
You can also recoup some of the original installation costs if you are eligible to receive generation and export payments through the feed-in tariff scheme.
Maintenance is generally low as the systems are very reliable.
From April 1, 2010, you could receive money for every unit of energy produced using a hydroelectric system.
