Off Grid Energy, a manufacturer of power solutions for the construction industry, has installed a temporary power hybrid unit at Kennington Tube station in the London Underground.
Four new customer passageways are being built at the station as part of work on the Northern Line Extension, which will extend the London Underground (LU) network from Kennington to Battersea Power Station via Nine Elms. Off Grid Energy is calling this hybrid unit its largest and most powerful to date.
As construction sites have a substantial impact on air quality, Off Grid Energy has provided the gridtogo battery storage solution with a power output of 195kVA. Reducing generator running hours, the gridtogo results in an improvement in fuel efficiency, and a substantial reduction in polluting emissions, CO2 and noise pollution – all while cutting costs, according to Off Grid Energy.
The unit also has a storage capacity of 350kwhrs – setting the bar for energy storage technology in temporary power. It can also allow the use of a smaller generator, resulting in further fuel savings. The use of smart monitoring means Off Grid can utilize real-time energy data from this project to judge how much power is needed for future similar projects and to better size generators in the future.
Due to the residential location of the station, using the existing noisy generator during unsociable hours was not an option. LU’s contractor approached temporary power experts Power Electrics to deliver a noise-sensitive solution for the time-critical project. By implementing the Off Grid Energy silent high power gridtogo system along with a modern super silent generator it allowed full power demand to be met 24/7, reducing the need to run the generator, enabling construction work to continue, according to the company. Power Electrics has now provided the 300kVA super silent diesel generator with the 195kVA hybrid system to deliver a total power capacity of just under half a megawatt.
When the battery located inside the unit is charged and the demand for power is low, the generator can automatically turn off and the energy stored in the battery is used to supply the load.
Earlier this month, the London mayor announced that hospitals, museums, offices, libraries, social housing and universities will be amongst the public buildings and small businesses set to become more energy efficient thanks to a new £500 million ($660 million) investment fund.
A recent study from the Green Finance Taskforce revealed that many public-sector organizations and small businesses want to install energy efficiency measures, but often can’t access the necessary finance.
