These payments are:

In addition to the above, additional payments are made for electricity exported to the grid.

* Below 30kW 75% of the generated electricity is 'deemed' exported no matter how much is actually exported. For the 85kW scheme we have assumed 50% is exported and the agreed Power Purchase Agreement rate is 5.5p/kWh.
** Assumes electricity costs 16p/kWh and for all the schemes we have assumed 50% of the electricity generated is used on site.

A 15Kw turbine
A 15 kilowatt turbine like this, using 78 litres per second with 32m of fall, produces about 72,000 units of electricity per year, worth over £5,500 per year on the Feed in Tariff income alone.

A 15Kw turbine
In total this 75kW scheme cost about £140k to install including the groundworks, power house and intake construction.

A 15Kw turbine
This 90kW scheme generates about 380,000kWh per year and cost in the region of £220k to install.
