Selling Your Electricity |
|
Segen will normally take care of obtaining permission from your local electricity network supplier (DNO) for you to attach a small wind turbine to the grid, but you must seek an agreement with a supplier, which may or may not be same company, to buy your generated electricity and claim your ROCs.
Selling your Generated Energy
You may sell your surplus generated power to any of the companies that are licensed to do so, and a number that deal with purchasing exported "green" energy are listed below. This is however a constantly changing list and the best supplier will change over time.
Some energy suppliers will agree to buy back your exported electricity for the same tariff as you currently import any electricity you require. You are advised to shop around the different energy suppliers to find out the best deal for you. Please note you are not legally obliged to have one agreement with the same energy supplier for your import and export electricity needs, but in practice this may not be practicable. You should also enquire about changing your electricity meter for a meter that measures both import and export of electricity (smart meter) with your energy supplier.
Recently the number of companies offering schemes has grown considerably and the rates you can get have increased considerably. Each scheme however is different and you need to read them very carefully to understand what will be best for you.
RWE npower Juice
One of the best schemes on the market today is from RWE npower as part of their Juice product range (http://www.npower.com/at_home/juice-clean_and_green.html).
If you would like to find out more about the npower micro-generation scheme then please download their fact sheet from our web site.
EDF Energy
EDF Energy has a small scale domestic renewable energy Power Purchase Agreement (‘buy back’ arrangement) that is available for EDF customers with renewable energy installations.
The agreement covers all types of renewable energy technology in residential situations up to 10kW of installed load. There are two payment options are available:-
Option A – (Metered) The current domestic export rate is 7.64p per unit (kWh) for Wind & Solar Technologies, and 5.00p per unit (kWh) for Small Scale Hydro.
Option B – (Un-metered) £10 per kW of installed load per annum.

Good Energy
Good Energy has four generator schemes: Home Generation, Offgrid Generation, Smart Generation and Commercial Generation. Their Smart Generation scheme is suited to the Westwind turbine and their Home Generation scheme suitable for our Iskra and Skystream customers. Details of the schemes can be found on their Generate Your Own page.
The Home Generation scheme currently for generators up to 6kW, pays 9p per kWh, but for all energy generated irrespective if it used within the property. It is therefore very attractive for smaller wind and PV customers who will be using most of the power within the property.
Their Smart Generation scheme is for generators between 6 - 75kW offers a current price is £43.41 per MWh for exported energy + £43.48 for ROCs with an annual charge of £93 for metering. The price may however vary over time and your exact location.
Ecotricity
Renewable Rewards is a scheme designed to help support customers reduce their carbon footprint. Customers with Solar PV, small wind turbines, small hydro power under 10KW capacity can receive benefits for their generation.
Ecotricity will pay you 9p for every unit (kWh) of electricity you generate. In return, you supply Ecotricity with the ROCs awarded to you by OFGEM on an annual basis.
Scottish and Southern Energy
A recently announced scheme, but only for Solar PV systems, offers a very attractive rate for exported power from your system and may therefore be of interest for larger PV customers.
SSE will pay 18p per kWh for all exported power from your system and will install an import/export meter to monitor the power being exported. SSE will do all the paperwork required for the ROCs, but this price includes them taking the ROC revenue.
For smaller PV customers, using most of the power within the property, this may not be the most appropriate scheme.

Claiming your Renewable Obligation Certificates
Some of the power schemes either include ROCs in the price or they will also arrange to sell the ROCs for you. If you wish to have a separate power sales and ROC agreement then you may do so, with a ROC broker.
Tradelink Solutions (http://www.tradelinksolutions.com/) are a specialist broker dealing in power purchase agreements, ROCs and LECs for small scale renewable energy installations.
Tradelink will be able to help you claim ROCs and/or LECs for the energy generated by your small wind turbine and can also advise you on the best electricity company to sell your generated power to.
Tradelink Solutions will charge you a specially reduced rate for Segen customers for the accreditation fee of £75 (normally £100), but this is only payable once your installation has been registered.
If you have any queries on the services that Tradelink Solutions can offer then please download their detailed fact sheet which contains a full description of the ROC scheme and Tradelink's contact details.
Listed below are other power companies that may purchase the energy you generate from your wind turbine for a better rate than your current supplier.
