Small Hydro Electricity Micro Generation .
How does it work?
A typical domestic 6kWh hydro system working at maximum capacity could produce 52000kWh per year, twice the house holds energy needs with the excess sold back the the national grid. You will of course need a constant source of flowing water.
What will it cost?
Small hydro will typically cost £10,000 to install, an initial £6,000 for the 3kW small hydro programme and an extra 3 kW at £1,000 per kw. This should save you 100% on your electricity bill and any excess can be sold back to the electicity supplier. If you structure your payments efficiently, then it may cost you very little, nothing, or even make you money. Please read on.
Assuming the water doesn't stop flowing and your property is run entirely on electricity and not gas or oil, we can moot the following example. If you pay for your installation by re-mortgaging by a typical £7,000 extra, this might add say £350 a year to your mortgage repayments, with interest rates at 5%. Generating your own electricity should reduce your bought in energy requirements from, for example, £1,000, to £0. Your expenditure has already fallen dramatically, you are in fact better off by £650 per annum. Selling any excess electricity back to the grid should also generate a reasonable return on your investment.
Remember too that the solar savings are tax free, so every pound you save on electricity is typically worth around £1.30 of your taxable income.
Savings.
Feed In Tariff applies. Savings will depend on the amount of wind, size of turbine etc.
