en.Wedoany.com Reported - Spanish renewable energy developer Grenergy has launched a reverse energy auction in Chile to tender 1.5 TWh/year of electricity supply. The power will come from solar plants and battery energy storage systems located in northern and central Chile, with the tender managed by its subsidiary GR Power.
This auction is aimed at generators, electricity retailers, and large consumers, helping these users secure competitive electricity supply for the coming years. According to the company, the supplied power will originate from solar generation and battery storage, allowing for the construction of electricity blocks tailored to different consumption periods. The design includes 960 GWh/year of battery storage capacity for nighttime periods and 540 GWh/year of photovoltaic generation, with supply expected from the second to third quarter of 2028.
The auction structure allows participants to bid on all or part of the electricity volume, which has been divided into contract units of 20 GWh. Bidders can choose contract terms of 6, 8, 10, 12, or 15 years based on their coverage needs. Interested companies must register by July 22, with the consultation period open until July 7, conducted through the electricity market platform Match Energía.
This is Grenergy's third self-initiated renewable energy auction. In 2022, the company conducted a similar operation in Latin America, a model aimed at expanding access to clean, stable, and competitively priced electricity for generators, retailers, and corporations. The company emphasized that since entering Chile in 2012, the country has become a key growth market in Latin America, solidifying its position as an energy investor and integrator of photovoltaic and storage solutions. One of its main projects is Oasis Atacama in northern Chile, which operates 2.5 GW of solar capacity and 14 GWh of storage; in addition, there is the Oasis Central project, which introduces a hybrid model to the central region, planning 1.4 GW of solar capacity and 5.1 GWh of storage.
The launch of this auction reinforces a key trend in Chile's electricity market: storage is no longer just a technical backup but is beginning to become a commercial component in building more stable renewable energy supply contracts. For large consumers, including the mining industry, the combined use of solar and batteries can improve time coverage, especially during nighttime hours when photovoltaic generation is unavailable. In this context, auctions that include storage capacity may become an important tool for securing long-term renewable energy supply.
