Kennington utilises UK’s most powerful silent hybrid energy solution

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.

The unit also boasts 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 as standard means Off Grid can utilise real time energy data from this project to judge how much power is needed for future similar projects and so 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.

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.

“Our hybrid power system delivers a cost saving, cleaner solution that also significantly reduces noise pollution in a sensitive residential area and is the biggest hybrid system for temporary power we have supplied,” said Danny Jones, CEO at Off Grid Energy.

“With a power output of 195kVA and storage capacity of 350kWhrs it is conceivably the most powerful temporary power hybrid unit in the UK with the largest battery storage capacity in the UK for temporary power. The added flexibility that comes from dual power supply and improved power quality means that the solution delivers a multi-layer win: Lower cost, cleaner air, less CO2, elimination of noise and greater power supply resilience.”

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. The features of the gridtogo help considerably cut running costs, CO2, noise pollution, and air quality levels while simultaneously reducing carbon footprint.

Jones added: “Power Electrics had a challenge to deliver a power solution for London Underground that had the least environmental impact in terms of air quality and noise pollution. Noise and CO2 emissions are major issues in London and construction is a key contributor to poor air quality. It is great that London Underground is committed to demonstrating best practice and that alternative technologies can deliver both environmental and cost benefits for temporary power solutions in London.”
