Colombia Launches Renewable Energy Auction With Battery Storage

Colombia is betting big on clean energy, and this time they're making sure the sun keeps shining even after dark.

The Ministry of Mines and Energy just launched a major renewable energy auction that includes something most countries haven't tried yet: separate contract categories specifically designed for battery storage systems. Projects that win contracts will start delivering power on January 1, 2030.

The auction offers four different contract types, each tailored to how Colombia actually uses electricity throughout the day. Solar farms can bid for daytime contracts running from 6 a.m. to 6 p.m. Battery storage systems get their own dedicated window from 6 p.m. to 10 p.m., right when families come home and flip on lights across the country.

There's even a hybrid option that combines afternoon and evening hours, encouraging developers to pair solar panels with batteries in a single project. A fourth option covers round-the-clock supply for projects that can deliver power any time of day.

The government designed this system to solve two problems at once. Colombia faces growing electricity demand starting in 2027, but the country also gets hammered by El Niño weather patterns that can wreak havoc on hydroelectric dams and power supplies.

All contracts run for 15 years, giving developers the long-term certainty they need to invest in major projects. Winners must have their systems up and running by the end of 2029, with one optional track allowing a 2035 start date for the 24-hour supply contracts.

The Ripple Effect

This auction could transform how an entire country thinks about renewable energy. By creating dedicated time slots for different technologies, Colombia is essentially building a market that values flexibility as much as raw power generation.

Battery storage has struggled to compete in traditional energy auctions because the rules weren't written with storage in mind. Colombia's approach sends a clear price signal: we need power when the sun goes down, and we'll pay for it.

The timing matters too. Colombia currently has just 1.59 gigawatts of solar capacity installed. This auction could multiply that figure several times over while adding significant battery storage to keep the lights on during evening peak hours.

Other countries facing similar challenges with climate variability and growing renewable energy targets are watching closely. If Colombia's model works, it could become a blueprint for designing smarter clean energy markets worldwide.

The country has set an aggressive deadline of July 31, 2026 for awarding all contracts.
