<p /> <p>DWP has outsourced the provision of its estate until 31st March 2018 under
a 20-year PFI contract with its private sector partner Telereal Trillium.</p><p> </p><p>Telereal
Trillium’s technical experts have undertaken regular extensive reviews (both site
based and desk-top studies) of the Department’s estate with a view to assessing the
practical and financial viability of investing in micro-generation. These have included:</p><p>
</p><p>• solar photo-voltaic and wind turbine generation of electricity; and</p><p>
</p><p>• solar and bio-mass generation of heat.</p><p> </p><p>Following this review
18 sites were identified for a site visit and more detailed examination by Telereal
Trillium’s technical experts and potential suppliers. Detailed business cases were
then developed for the biomass sites offering the quickest payback and with the potential
to meet the Department’s investment criteria. Unfortunately, although these sites
offered a practical means of generating renewable energy they did not meet the Department’s
investment criteria and so have not been pursued. Solar photo-voltaic and wind turbine
generation projects had even longer payback periods.</p><p> </p><p>The Department
also commissioned EDF to undertake independent surveys at five sites. These confirmed
the results of the work undertaken by Telereal Trillium’s technical experts in that
the break-even periods were too long to meet the Department’s investment criteria.</p><p>
</p><p>Telereal Trillium are continuing to assess whether reductions in costs and/or
improvements in technology will improve the financial viability of micro-generation.</p>
