Polish power grid targets zero-emissions transmission network by 2035

PSE, the Polish power grid operator, said Tuesday that it plans to transform Poland's transmission system into a zero-emission mix of energy by 2035. This is part of a longer-term strategy.

PSE stated that it would need to integrate 80 gigawatts of new renewable energy capacity by 2034, and 15 gigawatts of storage.

Even though coal's share in electricity is declining, conventional plants can still be used to provide backup power for intermittent power sources, and stabilise the?frequency? during power outages.

In a recent statement, PSE's chief executive Grzegorz?Onichimowski said: "We need to prepare the system for stable grid operation without conventional energy sources. They will still be required, but they are primarily needed to maintain energy balance in periods of lower renewable energy production."

PSE plans to manage grid-connected systems in 2030, with 1.5 million?prosumer installation - homes that produce and consume electricity, like those with solar panels. PSE will also implement grid forming measures in order to integrate intermittent sources and stabilise voltage and frequency.

Grid said that "failure to adapt operational mechanisms to the reality of a system with high renewable energy share led to one the most severe power outages in Europe - the blackout on Iberian Peninsula." PSE reported that a complete blackout could result in 'economic losses up to 40 billion Zloty ($11.13billion) per day.

PSE will examine the feasibility of constructing new cross-border links and expanding the existing ones, including increasing the capacity of the cable undersea with Sweden.

By February, the grid will have implemented a model for infrastructure protection. ($1 = 3.5934 zlotys) (Reporting by Marek Strzelecki, Editing by Louise Heavens)
