Santiago de Chile, December 5 (EFE).- Chile wasted up to 6 gigawatt hours (GWh) of solar energy in 2024 due to overloads on transmission lines, a phenomenon that will continue to increase in 2025, with 3.2 terawatt hours (TWh) discharged by August, according to the Renewable Energy and Storage Association (Acera).
Data from the Chilean association shows that lost energy represented 20% of total wind and solar production last year, which could have covered the annual electricity consumption of more than 2 million households.
Faced with this increase of 148% compared to last year, the company SolisStorage introduced in the country its new storage platform EverCore, which aims to reduce these losses and strengthen the energy transition.
The problem has worsened as Chile expands its renewable matrix, which has put pressure on demand for industrial storage systems.
For SolisStorage LATAM Chief Technology Officer (CTO) Sergio Rodríguez, “Chile positioned itself as a regional hub for energy storage system deployment and innovation as companies faced rising energy costs, the need for greater operational resilience and increasing variability in the network.”
Currently, Chile is one of the countries with the greatest renewable energy integration in Latin America, behind only Brazil, where solar energy accounted for 25% of national electricity at the end of June 2025. Antofagasta and Atacama lead the operation of photovoltaic parks whose installed capacity exceeds 11 gigawatts (GW) and where more than 4,000 megawatts (MW) are under construction, according to a report from the Chilean Generator Association.
However, according to reports from the research center Broadminded, if the entire energy potential was exploited, the share of renewable energy in the system would have reached 47% instead of the current 40%.
Therefore, conditions such as the lack of transmission infrastructure and lack of large-scale storage continue to result in significant electricity losses, resulting in greater operational uncertainty and rising energy costs for the private sector.
In this context, SolisStorage chose Chile as the first country in Latin America to launch EverCore, its new storage system for commercial and industrial (C&I) applications. A decision that, as Rodríguez emphasizes, responds to “the country’s growing demand for robust, scalable and intelligent systems” in line with its decarbonization goals.
“Chile was the ideal country to showcase this new stage. Its advanced renewable ecosystem, high C&I demand and cutting-edge energy policy created the perfect environment,” he added.
The presented solution integrates in a single device a hybrid inverter, storage batteries and an advanced energy management system (EMS), the design of which aims to optimize the operation of industries and companies, especially in times of greatest demand.
“EverCore represented a critical evolution for SolisStorage: from an inverter manufacturer to a comprehensive energy solutions provider,” said Rodríguez.
The official launch took place at an exclusive event in Santiago, where customers, partners and energy sector stakeholders evaluated the system as an alternative to address the generation and transportation challenges of the national electricity system.
The consolidation of solar projects in the north of the country has exceeded transmission capacity to the center and south, increasing the risk of a spill and forcing production to be curtailed at certain times of day.
According to the company, EverCore will make it possible to harness the energy lost today, increase the stability of industrial operations and reduce energy costs through better control of consumption.
For the director of SolisStorage, this technology will also be crucial for the industrial and commercial sectors, concluding that “storage not only supports operations, but also accelerates energy independence, cost optimization and user resilience.”
