npower Reports Solar Cells Gives National Trust Museum the Power to Generate its own Income

WORCESTER, England, November 8, 2010 - npower has reported that one of the UK's largest installations of
photo-voltaic (PV) cells on a historic building* has been fitted to the roof
of the National Trust's carriage museum at Arlington Court near Barnstaple in
Devon.

The 113 m2 installation will generate up to 6.3 megawatt hours (mWh) of
energy each year, saving the museum about GBP600 from its electricity bill
and generating income of around GBP2,270 per year by feeding energy back into
the grid.**

The project has been funded by sales of National Trust Green Energy
(www.ntgreenenergy.org.uk/) which is supplied by the charity's energy
partner, npower (www.npower.com/), and raises money to support low and
zero carbon energy savings projects at Trust properties.

So far 25 National Trust properties have benefited from the partnership
with npower with solar panels (www.npower.com/web/SolarPV/index.htm)
biomass boilers and ground source heat pumps helping generate energy and save
money on fuel bills, as the Trust works towards its commitment to cut its
overall energy demand by 20 per cent by 2020 and to switch to renewable
energy.***

The installation will also help protect the historic carriages in the
museum, with the cells helping to reduce the amount of ultraviolet light that
enters the building.

The completion of the work comes at the same time as the Trust and npower
announce the extension of their partnership for another two years.

npower spokesperson Matthew Cole, commented: "It's great that customers
who choose National Trust Green Energy are getting to see these big
investments in renewable energy technologies at their favourite Trust places.
The new agreement means more customers can get green electricity
(www.npower.com/web/At_home/electricity_and_gas/Products/Juice/index.htm)
and we'll be able to improve the carbon footprint of more Trust
properties."

Notes to Editors

    - * The size of the PV cells at Arlington Court are 113 m2, the second
      largest PV installation of National Trust buildings, the first being
      the Trust's central office, Heelis, in Swindon, of 1306 m2

    - ** The installed capacity of the array is 8.9 kWp, generating about 6.3
      MWh of electricity per year. It is likely that most of the
      electricity generated will be used on site, offsetting about GBP600
      of grid electricity and FIT income should be about GBP2270 per
      year. The work was carried out by Solar Technologies.

    - This project could not have been completed without the support of
      npower through the npower/NT Green Energy Fund. The Trust has been
      working in partnership with npower since 2007 offering a product called
      'National Trust Green Energy' which is electricity that is matched
      from 100 per cent renewable sources and it costs the same as npower's
      standard electricity.
