Greek power utility PPC signed an agreement for a 10-year power purchase agreement with cement producer Titan, the second industrial consumer to establish a bilateral energy supply contract with the utility, following metal processing company Viohalco.PPC’s agreement with Titan shares the same structure as the preceding deal with Viohalco.As a first stage, the cement producer’s energy requirements will be covered by electricity generated at PPC’s thermal and hydropower plants. A third-party supplier, energy firm Heron, will supply PPC’s energy output to Titan.At a later date, this PPA will develop into an entirely green-energy deal with all required electricity generated by PPC’s solar parks.Heron’s involvement in the power utility’s PPA with Titan is expected to further increase the energy its share of the high-voltage market. It recently rose sharply to 11.25 percent following Heron’s involvement in PPC’s PPA with Viohalco.
