British Hydro Network event - 29th June

11/5/2017

3 Comments

 
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. administrator@microhydroassociation.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."

Ofgem are now publishing details of the queue of applications for accreditation.  The report is presented in a Microsoft Excel spreadsheet.  The 16 May 2016 report can be viewed here as a .pdf file for Hydro 100kW and under.  There are no applications in the queue for this period for schemes over 100kW.

FiT tables 2016-2019

7/4/2016

Ofgem have published the new rates from 1 April 2016 here.

Although one pre-accrediation application (17 March) was withdrawn before 31 March 2016 bringing the 0-100kW deployment below the degression cap, the rates have nonetheless been reduced by 10%.

FiT degression caps

23/3/2016

1 Comment

 
The latest position on degression caps (i.e. whether and by how much they have been breached) is usually available on the Ofgem website here but the website is down at the time of writing.

The BHA have pointed out that there is currently only 24kW of the 1.1MW capacity available for this quarter in the sub-100kW FiT band for hydro.
 
If the maximum band capacity of 1.1MW is reached before the end of March, then a 10% contingent degression would be triggered which would lower the FiT rate for any future new schemes. If you attempt to pre-accredit a scheme which is greater than the remaining capacity you will both trigger the degression and suffer the 10% reduction for your scheme.
 
If you wait until April when new capacity is available you will only suffer a very small default degression.
