Microgeneration and Athgarvan Mill

I've added links below to a list of electrical power generating sites in Ireland in a Wikipedia article, and also written answers from a Dáil Éireann debate of Tuesday, 26 Jan 2010 on the Oireachtais.ie website. There may be sites that generate lower output, not listed in these resources. According to a list referred to by Minister Eamon Ryan and provided by EirGrid and ESB Networks, Athgarvan Grain Company Limited's installation in Athgarvan was generating 20 kW from its small hydro turbine. (The owner showed me this in 2001, but I can't remember anything about it). Also Silliot Hill was generating 1.255 MW from methane produced by the landfill. An installation at Celbridge Mills was listed as generating 55 kW.

I met Brian Byrne in the Valley Park this morning when out for a walk, and we were musing about how it would be great if there was a turbine that could generate electricity from the power of the Liffey. It wouldn't have to be a large device, and could power lights in the park and would be a wonderful demonstration of the power of water. The problem nowadays is that there's so much red tape implementing projects like this. Also, as far as I'm aware, land on both sides of a waterway needs to be owned to install a hydrogeneration system. However, this might only be the case for streams, when a "dam" has to be constructed, potentially flooding fields on the far bank.
