Penketh & Whittle Flood Risk Management Scheme

Temporary Power Solutions are a key area that can benefit from integrating battery technologies to reduce both emissions and fuel costs. Find out how VolkerStevin are saving thousands by installing a hybrid power solution.

Given the nature of these schemes they’re often in environmentally sensitive areas and/or near residential areas. So, reducing the impact on the surrounding environment is high on the agenda for companies entrusted with delivering these projects, and none more so than VolkerStevin.

This project will reduce the risk of flooding to property between Penketh Brook and Whittle Brook and the works involve a flood relief culvert on Penketh Brook beneath the canal and railway (and associated habitat creation) along with improvements to the Widnes Road trash screen (Penketh Brook).

The team will also install tidal gates on Whittle Brook and silt removal from blocked culverts.

THE CHALLENGE

The site is a 16 cabin set up located in between two key waterways, on a greenfield site near residential areas and businesses. Minimal impact on noise and air quality is a key objective of lead contractor, VolkerStevin. Add to this the planned Government changes to rebated fuels from 1st April 2022, increasing the need to further reduce fuel costs.

THE SOLUTION

An integrated hybrid power solution was the answer.

Instead of the more traditional single generator set up, site installed a battery storage unit (BSU) and energy management system (EMS) alongside a fuel powered generator.

This meant site could downsize from a 100kVA to a 60kVA generator by better controlling and regulating power through the EMS.

The EMS controls, regulates and monitors energy requirements on site and is programmed to switch specific devices off when not needed or in use.

The BSU can then power site when loads are lower (typically weekends and overnight).

On this particular site the EMS switched all non-essential energy consuming devices off at 5.30pm (lights, hot water, heating etc) and turned them back on the next a day at 5.30am, ready for the arrival of the site team.

This allowed the load to switch from the generator to the BSU during evenings and weekends saving thousands of pounds in fuel as well as providing periods of silent, emission free power

THE RESULT

By introducing cleaner energy solutions, the VolkerStevin team significantly reduced running costs for their temporary power solution, lowered their emissions and provided silent power over night and at weekends.
