Lignite, gas-fueled facilities on full to meet spike in demand

Electricity demand is expected to peak at 8,190 MW this afternoon, while the day’s overall demand will reach 163.258 GWh, an amount that will require input from virtually all available lignite and gas-fueled power stations so that the country can cope with the Barbara weather system, which has produced freezing temperatures and snowfall.

The RES sector is also greatly contributing to help the grid cope with significantly higher electricity demand and avert any fears of an energy shortage.

The country’s RES units are today expected to offer 79.59 GWh, roughly 50 percent of the day’s overall demand, while lignite and gas-fueled power stations are planned to generate 62.44 GWh.

According to power grid operator IPTO’s schedule for the day, five of power utility PPC’s lignite-fired power stations will contribute to the grid, these being Agios Dimitrios I, Agios Dimitrios III, Agios Dimitrios V, Meliti and Ptolemaida V, a new 660-MW facility still undergoing a full-scale trial run ahead of its launch next month.

As for gas-fueled power stations, PPC’s Aliveri V and Megalopoli V will be called into action, while the private sector will contribute with a Heron unit, two Elpedison facilities, in Thessaloniki and Thisvi, as well as a Corinth Power unit.

The same lignite and gas-fueled power stations were recruited to contribute to the grid yesterday, when the Barbara weather system made landfall, resulting in an electricity demand peak at 7,990 MW and overall demand of 161.080 GWh.

PPC ups Megalopoli V output to full capacity of 811 MW

Power utility PPC’s Megalopoli V power station in the Peloponnese has, for the first time,  begun operating at a full-capacity level of 811 MW following five years of production well below full potential, a restriction whose cost the utility has estimated at 200 million euros.

Power grid operator IPTO yesterday gave PPC the green light for full-scale production at Megalopoli V after an extended period of pressure applied by the power utility.

In the lead-up, PPC was forced to operate its Megalopoli V facility at 60 percent of its full capacity, 500 MW, following instructions from IPTO, noting the Peloponnese region’s existing network could not carry a greater amount.

Trial runs at Megalopoli V, a natural gas-fired combined-cycle unit, began in April, 2015 but PPC had never been given permission to boost generation at this power plant by 311 MW to reach full capacity.

Meanwhile, PPC’s Megalopoli III and IV units, both lignite-fired, were either shut or operated well below full capacity as a result of hefty CO2 emission right costs.

A swifter full-scale launch of Megalopoli V would have enabled the power utility to completely switch off the engines at loss-incurring Megalopoli III, a 250-MW unit, PPC has noted.
