Caterpillar has announced that Forsmarks Kraftgrupp AB has selected Caterpillar and its local Cat dealer Zeppelin Power Systems to supply six Cat 3500 Series industrial diesel engines for an emergency cooling system at its Forsmark nuclear power plant in Sweden.

The engines will power custom-made GSG cooling water pumps produced by Sulzer, a specialist in pumping solutions for the nuclear selector.  To meet new regulations from the Swedish Radiation Safety Authority, the pump packages will be installed as part of an independent core cooling system that would be used in the event of an emergency for the facility’s three reactors.

Together, these three reactors produce about 25 billion kilowatt-hours of electricity in a typical year, which accounts for approximately one-sixth of all the energy consumed annually in Sweden.

The new system will be installed in stages and qualified for seismic resistance.  The work is expected to be complete in 2019.

“Nuclear power provides about 40 percent of all the energy used in Sweden, so it is important to have systems in place that ensure the safe operation of nuclear reactors,” said Patrik Lundgren, project manager for Forsmarks Kraftgrupp AB.  “We selected Caterpillar and Zeppelin Power Systems due to their long histories and strong reputations for quality products that perform when they are needed most.”

Cat 3500 Series industrial diesel engines offer performance and durability for industrial applications through high power output, proven reliability and excellent fuel efficiency. 

Earlier this month the company’s Altorfer dealership announced the commissioning of a 500-kW solar photovoltaic (PV) utility-scale demonstration project in St. Charles, Ill., as part of a 20-year power purchase agreement with the Illinois Municipal Electric Agency (IMEA). 

Featuring more than 4,800 Cat solar panels, the 2.3-acre facility is located in the Legacy Business Center adjacent to the East Side Sports Complex in a western suburb of Chicago.

Caterpillar supplied the thin-film solar panels, inverters, controllers, and monitoring systems, while Altorfer Power Systems was responsible for installation, maintenance, and operation.

This is the second agreement between Altorfer and IMEA that utilizes solar PV power to help diversify the authority’s power generation capabilities. Altorfer Power Systems has commissioned a 1,000-kW solar PV facility in Rantoul, Ill., which produced 1.65 million kilowatt-hours of electricity in 2017.

“High-performing PV panels and decreasing capital costs are making solar power an increasingly affordable and attractive option for forward-looking municipalities that are looking to diversify their portfolios with clean, sustainable sources of power,” said Tom Schmit, sales manager for Altorfer Power Systems.  “IMEA and the City of St. Charles have clearly demonstrated their leadership and foresight as pioneers in municipal power generation through their growing support of solar technologies.”

The Cat Hybrid Energy Solutions suite is an innovative lineup of power systems that adds environmentally friendly solar panels, state-of-the-art energy conversion and storage technologies, and advanced monitoring and control systems to Caterpillar’s traditional line of reliable power generation equipment, which includes HFO, natural gas and diesel generator sets, switchgear and automatic transfer switches. The Cat Hybrid Energy Solutions technology suite is designed to reduce fuel expenses, lower utility bills, decrease emissions, and reduce the total cost of ownership while increasing energy efficiency in even the most challenging environments.
