A case study detailing the installation of a 64 kWp solar PV system and 92 kWh battery storage at an educational facility in Mombasa, Kenya, by Burhani Solar to reduce grid dependence and improve energy reliability.

This briefing by RMI argues that power sector leaders should reconsider planned coal-fired generation projects due to the falling costs of renewables and storage, evolving grid needs, and the risk of creating long-term cost burdens for taxpayers and customers.

China is strategically transitioning its coal power fleet from a baseload generation role to providing system flexibility to support the rapid expansion of wind and solar energy. The country is on track to fully retrofit its existing coal fleet for flexibility by 2027, though the report emphasizes that clean flexibility solutions, particularly battery energy storage, must scale up to avoid locking in emissions beyond 2030.

This report by the International Institute for Sustainable Development evaluates the financial support required for India to meet its 2030 clean energy goals across five key technologies: battery energy storage systems (BESSs), solar photovoltaic (PV), electric vehicles (EVs), offshore wind, and green hydrogen (GH2). It identifies cost gaps—the amount costs must drop to reach parity with conventional technologies—and assesses whether current government subsidies are sufficient to bridge these gaps.

This briefing by RMI argues that battery energy storage systems (BESS) are a cleaner, more flexible, and often more cost-effective alternative to fossil fuel resources for maintaining electric grid reliability. It details how batteries can manage variable renewable energy, provide critical stability services, and support grid restoration, while urging utilities to adopt all-source procurement processes to identify the most cost-optimal reliability solutions.

This briefing by RMI argues that current commercial electricity rate designs, specifically noncoincident demand charges, encourage inefficient battery storage use that can conflict with the needs of renewable-heavy power grids. The document advocates for a transition to time-varying rates and compensation for grid services to better align customer incentives with system-wide operational requirements.

This statement by the Rocky Mountain Institute (RMI) defends its 2014 research on 'grid defection'—the economic viability of customers disconnecting from utilities in favor of on-site solar and battery systems—against interpretations of a subsequent study by the Rochester Institute of Technology (RIT). RMI argues that while full grid defection may currently only be economical in Hawaii, the downward trajectory of distributed energy resource (DER) costs creates a systemic risk of stranded utility assets and empowers customers to influence the pace of decarbonization and grid investment.

This executive summary introduces a report by RMI that examines the value of battery-based energy storage on the U.S. electricity grid, specifically focusing on the impact of deployment location, the potential for 'stacking' multiple services to increase value, and the regulatory barriers preventing such utilization.

This case study examines the implementation of a hybrid solar photovoltaic (PV) system with Lithium-ion (Li-ion) storage at UV Tooling CC, a parts manufacturer in Cape Town, to mitigate the impact of systemic loadshedding on industrial production.

This report by the Public Affairs Research Institute analyzes the financial and operational crisis facing South African municipal electricity distribution and proposes integrating existing rooftop solar PV and Battery Energy Storage Systems (BESS) as a pathway to reduce bulk costs and improve reliability.
