Additionally, the project has qualified for an \u201cinternationally recognised\u201d carbon offset programme.<\/p>\n
In 2024, CIP reached final investment decision on the 220MW\/1,100MWh Arena BESS project in Antofagasta<\/a>.<\/p>\n Most BESS projects in Chile are paired with solar PV. While Arena is a standalone project, it\u2019s still located in Chile\u2019s northern region, where high irradiation levels have concentrated the country\u2019s solar capacity.<\/p>\n As reported earlier this year by our colleagues at PV Tech, solar and wind curtailment in Chile surpassed 6TWh in 2025<\/a>, up 8% year-on-year, according to Chilean renewable energy and storage association ACERA.<\/p>\n Without BESS absorbing curtailed generation, the situation would have been far worse. ACERA estimates that curtailment could have reached 8TWh, a 43% increase, if operational BESS hadn\u2019t stored renewable energy that would otherwise have been wasted.<\/p>\n ACERA noted that if all curtailed solar and wind had reached the grid in 2025, renewable energy\u2019s share would have been 49.4% instead of 42.4%.<\/p>\n Energy storage deployment is accelerating in Chile. If current trends continue, ACERA projects approximately 9GW of BESS, averaging 4-hour duration, will be operational by the end of 2026, quickly surpassing the country\u2019s 2GW BESS deployment by 2030 target<\/a> four years ahead of schedule.<\/p>\n
