WEB Aruba is reviewing a utility-scale Battery Energy Storage System (BESS) proposal intended to support island-grid reliability, renewable energy integration, and future system flexibility requirements. To support WEB Aruba’s internal evaluation process, WEB requested that K&M Advisors conduct a rapid benchmark assessment of current utility-scale BESS market conditions applicable to isolated systems like Aruba. The assessment intends to provide an independent, high-level market overview and quick check regarding indicative utility-scale BESS pricing, supplier and integrator positioning, expected implementation timelines and equipment lead times, prevailing technology configurations and battery energy management/control approaches, and relevant project references, particularly for island-grid applications.

K&M conducted a targeted market benchmarking exercise focused on utility-scale Battery Energy Storage System (BESS) suppliers, system integrators, and solution providers with experience in island-grid applications. As part of this effort, K&M engaged with approximately a dozen participants across the BESS value chain through direct outreach and market consultations. In parallel, K&M conducted desk research using publicly available information on reference projects in the Caribbean and other island-grid markets to assess typical project implementation schedules, battery procurement lead times, and deployment approaches. K&M also reviewed a range of industry reports and market publications to evaluate global and regional trends in BESS pricing, technology, and market development. Based on these findings, K&M prepared a concise assessment of current utility-scale BESS market dynamics and industry trends relevant to Aruba. The resulting Benchmark & BESS Trends Report summarizes benchmark findings, comparative market observations, indicative pricing insights, supplier and integrator positioning, implementation timeline considerations, and high-level conclusions relevant to future BESS deployment in Aruba.
