The Chilean Ministry of Energy has published its long-term strategic energy planning report for the 2023-2027 period. The Long-Term Strategic Planning (PELP) is carried out every five years and it consists of projected scenarios of energy and demand to identify the development poles for renewable power generation and guide investment decisions in terms of transmission. The 2023-2027 plan includes three different scenarios: Slow Recovery, Carbon Neutrality, and Accelerated Transition. 

According to the report, Chile’s energy demand is expected to be supplied through renewable sources, mainly wind and solar photovoltaic, with the exact composition varying according to the horizon of analysis. Up to 2030, the three scenarios are dominated by the need to expand wind generation capacity, mainly in the Taltal area (Antofagasta), and then with greater relevance from Maule to Los Lagos towards the end of the decade. At least 2 GW of storage is also expected to be developed by 2030, in addition to the projects currently under development. 

The scenarios present marked differences in their projections towards 2050, due to the influence of green hydrogen production and consumption variations. The three scenarios suggest, within the next 20 years, an expansion to evacuate wind generation capacity from Parinas to the Cumbre and Los Changos substations, as well as the extension of the system between the Alto Jahuel substation and Río Malleco, by at least 3 GW over a large part of the section, also to evacuate wind generation between these substations.
