With the global energy storage system market expected to reach $17.9 billion by 20271, battery energy storage systems (BESS) are emerging as the strongest solution to increase grid flexibility and reliability. Countries around the world are increasingly switching to BESS to drive greater grid reliability and broader adoption of renewable energy sources and rapid growth rates of 31.4 percent CAGR by 2027 have been projected going forward. Battery energy storage systems are particularly suitable for regions that are impacted by grid instability, such as the Philippines.
The contract won by ABB in 2019 will support two 20 MW sites and a further 40 MW site, to be commissioned in 2021. The remaining sites will be commissioned in 2022.
“Battery energy storage systems are transforming the market, driving wider adoption of renewable energy solutions, and helping to improve grid performance across the globe” said Alessandro Palin, President of ABB's Distribution Solutions Division. “In support of ABB’s 2030 sustainability commitments, pioneering solutions like the one in the Philippines will ensure that grids are more stable and will satisfy the reliability challenges associated with moving to a stronger mix of renewables.”
The project will support the Philippines’ ambitious plans to build a more sustainable future for its communities, by decarbonising energy generation and ensuring that 54 percent of its energy mix comes from renewables by 2040 (a sizeable increase from 29 percent of renewables in 2019).
To meet these targets, the country faces several challenges to ensure grid stability, including the length of power lines required to connect the diverse archipelago, as well as intermittent energy supply from wind and solar, which needs storage to act as a frequency regulator.
ABB has provided a packaged BESS solution to strengthen the reliability and stability of the local grid on Luzon, the largest and most populous island in the archipelago, and the island of Visayas. Both these fast-developing regions will benefit from BESS as part of the government’s ‘Build, build, build’ programme that aims to establish a ‘golden age of infrastructure’ to boost industry and tourism.
The solution is designed to avoid large frequency deviations which can result in costly equipment damage and disruptive power system failure.
The Philippines project uses ABB’s proprietary software platform ABB Ability Zenon to act as the intuitive interface to the BESS, allowing users to make real time decisions based on grid parameters to ensure performance stability.
To satisfy the complicated needs of the scheme and ensure easy and quick installation, ABB developed a complete solution that uses standardised building blocks that are scalable and modular. The building block designs include an integrated combination of Energy Storage Modules and power distribution equipment, that can be increased or reduced in capacity to suit specific site location requirements.
The BESS includes the provision of battery enclosures, ABB EcoFlex eHouse, UniGear ZS1 medium-voltage switchgear, integrated skid units, transformers and inverters in one single skid, with a connection to the grid.
Installation and energisation periods were reduced by up to 30 percent, as all equipment was delivered fully integrated and pretested before arriving on site. Adopting this philosophy also ensured a reduction in site works and associated costs for the customer.
