Dear Member,

As you well know, the hydropower sector has been hit hard by the recent maelstrom of Government policy changes and we now face a very challenging future. Intentional or non, the effects are real and we whilst we have been lobbying both DECC and the Treasury very hard and continue to do so, we have also been working with many MP’s and Peers in England and Scotland over the past 6 months. Amongst others, we have requested meetings with the Secretary of State, Amber Rudd and with the leader of the Conservatives in Scotland, Ruth Davidson.

In particular we have been supporting Baroness Featherstone in her work in the Lords to get the Government to rescind the tariff cuts through her ‘Regret motion’ which she has tabled. Her address to the Lords is Tuesday 2nd February and by bringing our numbers we can add weight to her plea – ‘Feed-in Tariffs (Amendment) (No. 3) Order 2015 Baroness Featherstone to move that a Humble Address be presented to Her Majesty praying that the Order, laid before the House on 18 December 2015, be annulled (SI 2015/2045). 20th Report from the Secondary Legislation Scrutiny Committee’

The BHA has also teamed up with one of our members, the Micro hydropower Association and their CEO Kate Gilmartin, so please add your name to the attached letter by signing our petition at the link http://www.publications.parliament.uk/pa/ld/ldordpap.htm

Please pass on to all those within your network and get them to sign as soon as possible.

Let me know if you have any questions

News from Regen SW

regen logo

Community and localised energy supply can benefit consumers, renewable generators and network operators. However, there are still many commercial and regulatory barriers to selling the energy you generate directly to your local community. In the context of increasing grid constraints, we need to look at how local supply can help overcome this barrier. So where do we go from here?

Sign the 10:10 petition to buy your power direct from local wind, solar and hydro here.

Join us for the Community Energy Markets Conference, 25 June, Bristol.

This conference will address the next steps for community energy markets. We will examine what local supply projects are currently in place, what issues they have faced and how policy or regulation can help solve these problems.

Sessions include:

  • Policy overview and context
  • Examples of local supply models
  • How local supply can overcome grid constraints
Confirmed speakers:
  • Fiona Booth, head of community energy, DECC
  • Jeff Hardy, sustainable energy policy team, OFGEM
  • Sonya Bedford, partner, Stephens Scown
To book for this conference please click here.Regen are offering community energy groups in our network a discount of £75 off the members rate bringing it to £50 + VAT.Full details and booking are available here.  Use the code ‘discount’ when making your booking.

Gaia Vince, Anthropocene & more

An American friend of mine suggested I read Gaia Vince and her latest book Anthropocene a journey through our Planet. I’m normally into spy thrillers and the like so getting into something substantial like this is quite a challenge if like me you read at bedtime and the eyes close ever more quickly.

So I got started and the first chapter was all about the high villages of Nepal and the problems that they are experiencing. Pollution , lack of water, lack of education and modern technology. Frankly the sheer physicality of the lives people in Nepal are leading and their resilience was inspiring within only a few paragraphs.

Then the earthquake struck and thousands of deaths, people made homeless, lack of food and water etc etc

My adventure into Gaia’s book was warning of the dangers. If you dry out the Mountains, lose the Glaciers the earth becomes unstable. Soon the tectonic plates begin to re-act and the inevitable result is earthquakes and many of them.

Today people are living outside because daily quakes are happening and the people are afraid to go inside even if their homes have survived.

You could despair, wring your hands and send off another cheque to Oxfam or invest in a copy of Gaia’s book. It will inspire you with what individual people are doing. One man is creating Glaciers to replace the ones lost by global warming and its effects. Another group are creating internet networks almost out of tin cans. Renewable energy is being developed but they must be careful not to overuse Hydro as water is such a scarce commodity. Parallel this with Chile and its plan to destroy parts of the wilderness in Patagonia with huge hydro schemes to fuel growth thousands of miles away in its cities. This for a country that has huge seaboard boundaries that could create networks of on-shore wind turbines, tidal and wave power projects and save Patagonia.

Anyway I hope I have given you a starter for ten and a reason to buy the book.

If you want to know more from the people of Nepal whats happening on the ground take this link to:

Of this I shall write more very soon but here`s another thumbnail from the US.

My friend sent me the following latest report from the USA which in part is positive in part what we expect. But with knowledge and communication we can better tackle the future together.

” Although our leaders here in the US are far behind other leaders around the world there is a lot of activity. Solar installations on homes and businesses as well as major power plants are rapidly on the rise, wind farms have proven to be especially profitable and are become common in most US states and our rapid development of natural gas has at least made a dent in the coal fired power plants (I like to see the natural gas become a thing of the past as well but that seems unlikely in the near future). Unfortunately fracking for oil has been so successful that gasoline prices have dropped and Americans with very short memories have begun buying SUV’s again at a record pace. I wonder if the oil companies have offered lower gas prices because hybrids and EV’s were starting to catch hold of the public. Gas has started to rise again and will likely pass $4 a US gallon this summer. The new SUV owners will wail and complain that the President is to blame while oil companies will for the nth year in a row see record profits. So it goes”

100% renewable and self sufficient North Dorset in Electricity – here`s how

100% renewable and self sufficient North Dorset in Electricity – here`s how

The most recent statistics from the Department of Energy and Climate Change show that North Dorset consumes 290.8 GWh/yr

The last census shows 30,397 households, only 11% of those being flats. Quite a few of these dwellings already have PV installed on their roofs but that number is likely to increase substantially when PV becomes so cheap that it will make better financial sense to install it than pay for all your electricity from the grid. This grid parity (without subsidy) is expected to come about as early as 2020. More than half of houses have close to south facing roof space and it’s reasonable to assume that 60% or so could accommodate a 4 kW array. These would generate around 65 GWh/yr

There are 3,800 businesses in North Dorset including farms. Not all will have their own roof space but all those steel sheds on industrial estates and agricultural barns have low pitched roofs that are viable for PV whatever their orientation. A quick look at Google Earth shows at least 50 big enough to take around 50 kW in the towns and farm barns would probably double that. So I estimate these could generate 5 GWh/yr.

There are already quite a few large and small ground mounted solar farms installed and enough space to generate the equivalent of the districts needs without impacting food production. A reasonably large solar farm is 10 MW generating 10 GWh/yr so 29 of those would equate to the district’s annual consumption.

There are at least 6 small 20 kW wind turbines (up to 20 m mast and 7 m blades) in North Dorset tucked away virtually un-noticed. The landscape could easily accommodate 50 small turbines without travellers and walkers constantly coming across them. They could generate 0.35 GWh/yr.

The River Stour and its tributaries already has 4 hydro turbines installed at mills and weirs with another 5 to be installed soon and potential for at least 6. They range from 3.7 to 89 kW and in total could generate 1.75 GWh/yr.

Now the elephant in the room, which is big wind power They may be very much out of favour with a vocal minority punching well above their weight but the fact is that a 2.3MW on-shore wind turbine is the cheapest source of renewable electricity. It would require 60 of these to generate the equivalent of all the district’s electricity and that could not be accommodated easily. I would say a maximum of 20 could be found a home and 10 would be more realistic and they could generate 48.5 GWh/yr

So North Dorset could generate equivalent to all its electrical need with;

65 GWh/yr from domestic roof tops

5 GWh/yr from commercial and agricultural roof tops

0.35 GWh/yr from small wind turbines

1.75 GWh/yr from hydropower

That leaves 218.7 GWh/yr to be found from a combination of large solar farms and wind turbines. Personally, I would like to see 10 large wind turbines, some of those to be clearly viewed from my back garden. That would mean 17 x 10 MW solar farms to take up the slack.

    "Keith gives a cogent and totally understandable summary of how North Dorset with just a number of small steps could create 100% of its energy needs renewably.
    Think what if every district, County did a similar exercise how simple going renewable could be and how we could see the end of coal, gas and nuclear power for ever.
    This is now not in the realms of fairy stories its hard economic sense and will support reductions in climate change temps and give us better air quality all at the sametime. "

Pymore, Bridport – Community Hydro Power Event

Three weeks ago we described (here) how members of Dorset Energized had been invited to investigate the possibility of installing a small Hydro Power electricity generating station on the river Brit in Pymore near Bridport.

Well things are moving along and to build momentum on the 22nd September at 7.00 pm a Tea & Cakes event is being held at the Weir itself, in Pymore, where you can find out more about what is being proposed. It will also be an opportunity to pledge money toward the development, an investment in a better, greener, cleaner, future.

So if you have the slightest interest in hydro power, community energy, or are just curious, please come along and meet the people involved – a mixture of local residents and people with experience of developing community energy projects.

Would you like your community to generate its own electricity from the river

    "Thanks for your questions Monty. If the management committee agree use of the river bank for a meeting next Monday, I hope you can join us and would appreciate it if you can ask further questions that I will answer as best I can. I want to emphasize that in my view, this has to be a community project and should not proceed further unless there is a clear will from the management company and residents to do so.
    The drawing is representational only and the turbine house has to fit in with the visual aesthetic of the site. It would need to be placed above flood level, as would the generator.An abstraction license, flood risk consent and possibly impoundment license would be required from the Environment Agency. The project design and negotiations with the EA would be lengthy. The site owner (the management company?) has right of access and must give their permission. A resident of Pymore (Jonny) has publicised the Monday meeting to all in Pymore and Management company directors will – I presume – carry above average weight at the event. The power could go three ways from the 3 phase generator to three different properties where the grid connections would be made. There are numerous design choices. I believe the project should be community owned. Again, there are choices as to the structure.`There are lots of discussions that could be had. I believe Vince and I have the answers to most questions that can be thrown at us but we want to hear the views of the company and residents. "

    "Dear Monty, thanks for your comments which are really what we are exploring on Monday. We want to hear from everyone locally about their feelings, is it good idea , should we go forward together and explore all the problems. requirements and possibilities. I am sure Keith will be able to answer many of the technical questions and I am there to talk about community share schemes. But its your project and local desires that count. "

    "Interesting and fine in theory. No account seems to have been taken of what happens to a wooden top structure that it subject to major flooding at that point maybe 2-3 times a yeard. Also, what permissions are needed and from whom. Who ‘owns’ the existing structures in the river at that point? The Environment Agency? Have they given any permission? What access rights would be needed and from whom? Has Pymore Villoage Management Company been approached? Where would the power produced ‘go’? Where would it be connected to the grid – on whose property? Who would own/manage the installation – and administer the finances? What track record do they have? Monty Crook, Pymore "

Now You See it Now You Don`t, Govt Support – Again

The rate of feed in tariff for each technology is reviewed every 3 months and if more than a certain designated megawattage is installed then that triggers a drop in the tariff.

This has just happened for hydropower, wind and AD. PV remains untouched this round. See http://www.british-hydro.org/news/decc_confirm_10_degression_for.html and follow the link.

For a hydro scheme you can pre accredit with Ofgem to fix you tariff rate at the current level if you have the required Environment Agency EA licenses but have not yet installed. Hydro schemes take years to develop due to the complexity of EA license requirements and a long time to install because of the bespoke nature of each project (no off-the-shelf-solutions as with solar and wind. So there is a large proportion of pre=accredited but unbuilt hydro schemes that have triggered this degression. Worse still, we are expecting another 10% degression in July 2015. When you add to this the recent rise from £135 to £1500 for EA licensing you can see that hydro is fast becoming unviable.

We develop these renewable projects because we know they are needed to mitigate climate change and we are environmentalists. But this government has constantly changed the goal posts and keeps the industry destabilised and performing well below its potential. Ed Davey has done the best he can at DECC and was until recently ably supported by Greg Barker (who fellow Conservatives accused of “going native” within DECC ie agreeing with Ed Davey’s line). But he has been partially undermined by George Osborne who has fossil fuel leanings and probably doesn’t want to see those interests undermined by a renewable industry that is too successful.

I would say from recent RE generation stats, you can see that with stable support and let off the leash, RE could kill off the fossil fuel industry quite quickly.

Community Hydro Energy Proposal – Pymore, Bridport

Energize Stur Valley (a group comprising several people from Dorset Energized) – were asked by members of the local community to investigate the viability of installing a small hydropower electricity generation set-up on the river Brit, which runs through the village of Pymore near Bridport.

We at Dorset Energized are enthusiastic supporters of community led renewable energy schemes – and a great way to provide support is by giving practical assistance:

A site survey was carried out and a proposal has been created – you can see it below.

Would you like your community to generate its own electricity from the river
