COMMUNICATION ‘BLACK SPOT’ FOR TRAIN DRIVERS
The rail network uses a series of permanent radio transmitters to enable communication with train drivers along the rail network. At Sutton Coldfield there is ‘black-spot’ which requires a new transmitter to be installed. Temporarily a mobile transmitter has been erected, but with no current mains connection a temporary power source is required.
The client was looking for a temporary power source that could run 24/7 & would require minimal attention. Originally the client asked for a solar panel solution, however, due to limited space this was discounted. The client then asked for the smallest generator complete with an external fuel tank, this would be a 20kva generator. They were advised against this due to the small power required – only 150Watts. The problem with this is that the generator would be heavily under-loaded which wouldn’t be good for the generator & would require daily attention and oil replenishment. We would not be able to supply any smaller generator as they are not capable of taking an external fuel tank & would therefore need refuelling. It would not be a supply & forget solution.
The most effective solution was therefore our gridtogo™ battery storage solution with remote monitoring, and a 20kva generator. In this genset solution the main power supply would come from the battery storage unit & the 20kva generator would only run when the batteries needed replenishing. The generator will only need to run for approx. 6-8 hours every week thus reducing the issues encountered with under-loading, and also saving approx. 400 Litres per week of diesel.
Hybrid Power Hire supplied technical support on site to ensure the installation was completed correctly.
Generator run time was reduced by 161 hours per week, which gave a weekly reduction in fuel of approximately 400L. The average fuel price per L on site was 66p which equates to a weekly saving of £264.
Due to the proximity of the site to the live rail line, attending to make fuel delivery and for other maintenance involved a costly and convoluted process to grant permission and ensure it was safe to work. Significant reduction in the need for refuelling the system had signifiant impact in this activity.
With the reduction of fuel and run time of the generator, the project saw significant CO2e savings.
“We were provided with a novel solution that overcame the challenge of having no available power supply. This helped us to get our equipment up and running in a timely manner to meet an urgent deadline on an operational network in which we play a key role as a trusted partner of the rail operator. The solution is intelligent, cost effective and environmentally friendly.”
