3. COST SAVING / REVENUE GENERATION
With a battery storage system:
Generate own Renewable Energy or buy
electricity from the grid when it is cheap – then
use or store in the battery
REVENUE GENERATION
COST SAVING
COST SAVING
• Use it yourself when electricity is expensive
• Replace a diesel generator for standby
power
• Sell it to others when electricity is
expensive

Project information
• Installed battery power: 60 kW
• Battery supplier: Tesvolt
Project
• Location: London Borough of Hounslow
Commissioning: January/ February
2016
• Installer: Revolution
The London Borough of Hounslow has
unveiled what it claims to be the largest PV
array by a local authority, and the first to
incorporate battery storage.
The borough invested £2 million to install a
1.73MW array atop Western International
Market (WIM) near Heathrow with the
intention of turning it into a carbon-zero
attraction.
