AleaSoft Energy Forecasting's analysis of energy storage projections indicates that storage projects need to determine revenue-maximizing configurations, anticipate changes in opportunities for arbitrage and frequency regulation service participation, assess the impact of increased battery penetration on these revenues, and determine the optimal sizing of hybrid projects. These issues are particularly critical for standalone systems and hybrid facilities. The company's AleaStorage division prepares forecasting reports for storage projects to optimize energy storage system revenue, sizing, and profitability.
