Netherlands-based rental power firm Bredenoord says it will produce an extra 30 of its ESaver mobile hybrid generator systems and put them on the market through its rental programme.
The move comes after a successful test run of the systems in partnership with contractor Dura Vermeer, which piloted 10 of the ESavers.
The 15kVA, 3ph, 400V Esaver system comprises a battery pack that recharges via solar cells, in conjunction with a diesel generator. At peak power demand times or when the battery charge is low, the generator engine switches to full capacity. The system can be combined with power generators with varying capacities, Bredenoord said.
In late 2013 Bredenoord and Dura Vermeer completed a pilot project that used 10 400V ESaver systems in combination with a 15kVA generator for construction and infrastructure projects. The companies reported that initial estimates of 40% fuel savings had been exceeded and that 70% savings are possible under certain conditions.
“The online ESaverclient portal provides clients with continuous site monitoring of their fuel savings and emission reductions”, said Margien Storm van Leeuwen, new business and marketing manager at Bredenoord. “We analyse this data and thus, together with the client, we can ensure the best possible use in each specific situation. [This] results in considerable savings, and has been an important motivation in further expanding production”.
Bredenoord general manager Jaap Fluit said, “We are heading for a society in which we will be more careful in our use of natural resource and emission. In practice the ESaver proves perfectly well that trustworthiness, certainty and sustainability can be combined with optimal cost-effectiveness. In particular by making existing technologies more sustainable we create a win-win situation. Fuel-savings by means of using our current machinery.”
