Between the DC batteries and the electrical grid, the PCS serves as an interface. How does a PCS work? To achieve the bidirectional conversion of electric energy, a power conversion system is a component connected between the energy storage battery system and the power grid.
Energy storage converter (PCS) consists of power, control, protection, monitoring and other software and hardware components. Divide it into single-phase and three-phase. Single-phase PCS usually consists of a bidirectional DC-DC step-up and step-down device and a DC/AC AC-DC conversion device. The DC end is usually 48Vdc and the AC end is 220Vac.
The energy storage systems described in this publication are a natural addition to PV solar and wind power instal-lations. They facilitate the integration of renewable energy with the grid by virtue of capacity firming and ramp rate control functions. The end result is more eficient utilization and availability.
In 2025, lithium-ion battery pack prices hit a record low of $108/kWh across all segments, with stationary storage systems plummeting to $70/kWh—a staggering 45% drop from 2024 levels. According to BloombergNEF's Levelized Cost of Electricity 2026 report, the cost of battery storage projects plummeted to new lows in 2025 even as most other clean power technologies became more expensive. This was driven by overcapacity in China, fierce competition, and the widespread adoption of cost-effective. The global battery market is experiencing significant growth, driven by the accelerating demand for electric vehicles (EVs) and energy storage systems (ESS) 3 5. Wider deployment and the commercialisation of new battery storage technologies has led to rapid cost reductions, notably. Some trends in the auto sector can be counted on year-in, year-out: Americans will keep buying big pickup trucks, SUVs will continue to take market share around the world, and Toyota will insist fuel cell vehicles are just around the corner. Add to that list, falling battery prices.

By shifting a significant amount of power supply to natural gas, EDP reduces El Salvador's reliance on diesel and heavy fuel oil-fired power generation, offsetting 600,000 tons of carbon dioxide emissions per year, and provides grid support to facilitate more renewable energy penetration, further diversifying the country's energy mix.
Despite the enormous challenges, including supply-chain disruptions, travel restrictions, airport closures, global financial volatility, and Salvadoran COVID-19 mitigation measures and regulations, the power plant began commercial operation in October 2022. EDP is a transformative investment in El Salvador's clean energy future.
From there, the gas powers 19 internal combustion engines and waste heat feeds one steam turbine. Two 230-kV electric transmission lines, one of which connects to the Central American Electrical Interconnection System, provides added grid reliability to the region and opens further opportunities for renewable energy in El Salvador.
Invenergy served as lead developer of the EDP project with the support of El Salvador-based partners Grupo Calleja, VC Energy de Centroamerica and Quantum Energy. To construct the project, Invenergy worked with a consortium of global project partners including BW LNG, BW Offshore, SAAM Towage, Boskalis, Wärtsilä, Elecnor, and Shell.
In addition to meeting nearly one-third of El Salvador's energy demand, EDP is projected to help the country meet its climate goals by reducing carbon emissions by 600,000 tons annually. The project has also been a catalyst for job creation and growth in the country.
In total, the project represents an approximately $1 billion investment in El Salvador. At least $10 million will be invested in economic and social works during the term of the power purchase agreements, strengthening local communities with a more than $500,000 investment per year.
