Promens Packaging, UK: generated 1.2GWh solar power, utilised 970 MWh, exported to the grid the remaining 191MWh -saved £50,000 GBP on electricity bill.

One year after more than 7000 solar panels were installed on the roof ofPromens Packaging's plant in Beccles, Suffolk, UK, the system has now generated more than 1,000,000 kilowatt-hours (kWh), or 1 gigawatt-hour (GWh), of green electricity. Lightsource Renewable Energy installed the system and operates it, leasing the roof space from Promens and installing the photovoltaic (PV) panels free-of-charge. In return, Promens benefits from substantial savings on its energy costs because it can run a significant part of its operations on the much cheaper "green" electricity it buys from Lightsource.

Adrian Banks, engineering manager at Promens Packaging in Beccles reports, "From July 2011 to the end of June this year we have generated 1.2GWh, utilised 970 megawatt-hours (MWh), exported to the grid the remaining 191MWh and in the process [saved more than] £50,000 GBP (~$78,000 USD) on our electricity bill. These are clearly significant figures and we would expect the benefit to increase further over the next 12 months, especially with energy tariffs going up."
