This was Marchington landfill site, it is now a closed site that is still producing Methane gas from the waste. This gas is extracted from the landfill and used as a fuel to run a generator which is on site.
Currently the generator is exporting around 200 kilowatts an hour, every hour, 24 hours a day, 7 days a week, 365 days a year. This power is exported back to the national grid and is enough power to run around 5000, 40watt light bulbs all day every day.
The cache its self is a camouflaged screw top container, you will not be able to see it in its hiding place from outside the gates, but a rummage around in the places you can't see and you will find it.
Good luck
