Botswana has received an $88 million loan from the World Bank for its first utility-scale battery energy storage system (BESS). The 50 MW/200 MWh project will allow for the stable integration and management of renewable energy on the nation's grid.
An international team led by researchers from the Australian environmental and energy-focused unit of RINA Consulting, part of Italy-based RINA, has examined the potential to deploy floating photovoltaics (FPVs) at hydropower plants (HPPs) in Ecuador and has found that, out of 70 HPPs, 11 have the potential to co-locate FPV systems greater than 15 MW.
BNEF has estimated that 92GW and 247GWh of energy storage, excluding pumped hydro, will be installed worldwide in 2025, a 23% increase in megawatt terms from the 2024 total of about 70GW and more than double the 44GW BNEF reported for 2023.
Buyers typically pay between a few hundred million dollars for mid-size projects and well over a billion dollars for multi-hundred‑megawatt installations, depending on capacity, duration, and interconnection requirements.
BloombergNEF estimates these costs will fall further to USD 113/kWh by 2025 and USD 80/kWh by 2030. 5 MW/10 MWh BESS project would cost around NPR 410 million, including transportation and installation.
Grid-tied solar dominates the market for good reason: With 2025 system costs ranging from $2. 00 per watt installed and federal tax credits of 30% through 2032, grid-tied systems offer the fastest payback periods (6-10 years) and highest returns on investment without requiring.
