14 billion to promote energy transition and renewables

The transmission system operator publishes the 2020 Development Plan and announces: half of the new works will be invisible. 40 GW of higher RES power can be connected to the grid.

Enabling the energy transition and encouraging the full integration of non-programmable renewables into the Italian system. These are the objectives that Terna chooses for the future of the national electricity infrastructure. The 2020 Development Plan will set them in black and white.

The company has allocated EUR 14 billion to support 27 projects, for a total of 300 km of new power lines. And half of them will be invisible, because underground or underwater.

In addition, the removal of obsolete infrastructure and the upgrading of existing infrastructure will reduce annual energy losses by 1,000 million kWh.

To achieve the objectives of the Italian PNIEC it will be necessary to install at least 40 GW of wind and photovoltaic power by 2030. This future capacity, writes Terna, will have significant effects on TSO’s grid management activities, especially in terms of instant by instant balancing of production and demand.

In this context, pumped storage hydroelectric power plants can offer “Energy Intensive” type services. What does that mean? That they can help operators to manage periods of overproduction and contribute to the resolution of network congestion.

To date, in Italy there are 22 pumping systems with a power of about 6.5-7.6 GW. But according to PNIEC 2030, the national centralised storage would need another 6 GW. In order to continue in this sector, Terna suggests defining an ad hoc regulatory and contractual framework capable of introducing long-term price signals to stimulate investment in new pumping.
