Grid to rely on lignite units amid extreme weather for 2 more yrs

The country’s grid sufficiency will rely on power utility PPC’s high-polluting and high-cost, for the utility, lignite-fired power stations for at least a further two years whenever extreme temperature fluctuations are experienced, as was the case last week, on Friday, when the heatwave pushed demand up to 9,258 MW, as well as Wednesday, when demand rose to similar levels.

PPC’s group of old lignite-fired power stations will need to keep offering solutions until at least 2023 during extreme weather conditions, be they heatwaves or snowstorms, a situation that will need to be seriously taken into account by the committee responsible for the new National Energy and Climate Plan (NECP).

The committee will stage its first meeting today to begin preparing the new 2030 NECP. Many uncertain factors still remain.

According to the existing NECP, now being revised, new natural gas-fired power stations offering a total capacity of 1,650 MW, plus Ptolemaida V – a lignite-fired unit to be converted to a natural gas-fired unit in 2025 for an eventual capacity of 1,000 MW – will need to be launched by 2030.

The new NECP will anticipate greater RES penetration by 2030 than the existing NECP. The existing plan expects renewable energy sources to cover 62 percent of overall electricity demand by the end of the decade, whereas the new NECP will increase this level to 72 percent.
