Power production and distribution utility Alpiq has commenced operation of its first power-to-heat system in Niedergösgen, Switzerland.
Located on the premises of the Gösgen hydropower plant in the canton of Solothurn in Niedergösgen, the new system uses two electrode boilers to generate process steam.

With each boiler having an electrical output of 11MW, the new system will enable Alpiq to provide negative balancing energy on the ancillary services market and can alternatively be used to produce process steam for industrial purposes.
Ancillary services are used by transmission grid operators to balance the differences between energy produced and consumed. This helps ensure the stability of the power grid.
Power-to-heat technology is a flexible and efficient solution for this balancing function, which has become increasingly important for grid operators due to rises in fluctuating power from wind and solar facilities.
Alpiq’s new system will be able to supply a paper factory with the process steam, while the Gösgen nuclear power plant undergoes annual inspection.
