Cable line and internal power network for Helme Energia’s 110 kV substationKirikuküla and Patküla, Helme, Valgamaa

Graanul Invest, a producer of pellets used for heating, built a combined heat (15 MW) and power (6.5 MW) plant in Patküla, Valgamaa. Merko’s job was to connect the new combined plant with Elering’s 110 kV network, and to build a 15 kV internal power network for the plant. We built a (15 kV) cable line of about 4 km that transfers green energy produced in the new combined heat and power plant to Elering’s network, and installed a 10 MVA step-up transformer at the supply point. The new combined heat and power plant was connected with the power Network in August 2012.
