The BHA are holding a one day event for the Hydro Network, incorporating a full programme of speakers, networking opportunities and a technical exhibition showcasing the latest in hydropower innovation and expertise.
A broad cross-section from the industry will be involved, bringing together industry professionals, experts and some of hydropower's leading practitioners to provide an insight into many of today's opportunities and challenges.
Engage with your industry, generate leads and showcase your brand at the technical exhibition
Full Details & Booking Information
There will be a discounted rate for MHA members and community groups, so please get in touch with me if you would like the discount code. firstname.lastname@example.org
Eel regulation in England and Wales
A study into the Environment Agency's regulations has been conducted by the EA themselves following pressure from the hydropower industry. This presentation by Olly Paish of the BHA gives some insight into the results.
In summary, the requirements for screen sizes for low head hydropower schemes will be for mesh size to be <=12.5mm, not <=2mm.
The EA have recently released details of various studies which in some cases relate to hydropower - see below from the EA, especially report no 3.
"The table below provides the titles and hyperlinks to the Evidence reports produced with our Evidence Directorate. Appendix 1 is a work in progress that is attempting to identify other projects (which we do not lead on) that may be of interest to the Hydropower sector."
