Swed-Mobil has been the official Volvo dealership in St. Petersburg, Russia since 1994. The challenge raised by this car dealership was the provision of self-sufficiency in heat and power, both for their showrooms, as well as attached workshops. The building in question extends over several levels with parking spaces and a total floor area of 16,000 m². Special features: Self-sufficiency in electric power without export of excess to the grid. The solution: A WOLF CHP unit. The use of a combined heat and power unit provides a reliable, affordable and viable provision of electric power. This allows the business to generate electricity in standalone operation and with the highest level of efficiency, whilst using the heat generated as a by-product for heating purposes.
PROJECT: Volvo center St. Petersburg
FUNCTION: Car retailer
TASK: Stand-alone provision of heat and power
SIZE: 16,000 m²
PROJECT YEAR: 2012
The installation comprised two GTK-240 CHP units with 237 kW electrical and 372 kW thermal output, as well as one GTK-100M unit with 100 kW electrical and 148 kW thermal output. All three units can be operated in stand-alone mode parallel to the grid, as well as in combination with a mains supply. The installation of the CHP unit resulted in a reduction in energy spending of around 30 %. The investment will pay for itself in around 3 to 4 years.
