Assessing the potential of hydropower
With high electricity prices and uncertainty, farmers with steep land and high, consistent volumes of rainfall may consider hydropower.
Hydroelectricity is derived from the power harnessed from the flow of falling water, typically from fast-flowing streams and rivers. Presently about 2.5% of Ireland’s electricity generating capacity is in the form of hydropower.
Considerable unexploited hydropower potential exists in Ireland at the small to micro-scale level. Some of the power generated can be used on the farm, saving it on its electricity bills – a saving that is expected to become more significant as conventional electricity costs rise.
In addition to the Microgeneration Support Scheme, it can generate an income from power which is exported to the national grid and earns an export tariff. This is paid by the buyer of the power. By investing in a small hydropower system, it is possible to reduce exposure to future fuel shortages,price increases and help reduce air pollution.
At an upcoming Teagasc Farm Business Options webinar, Fiacc O’Brolchain will speak to Barry Caslin, Teagasc, about the option to generate electricity from hydro. Areas to be covered include: planning requirements; types of hydro; feasibility studies; selling to the grid; cost of construction; maintenance costs; river/site suitability; protecting the spawning fish; labour input; Government agencies involved; and where advice can be sought.
This webinar will take place on Wednesday, 12th April, from 11am to 12pm.
