What They Do
Energy Toolbase focuses its core technology on software for solar photovoltaic (PV) and energy storage systems (ESS), providing a SaaS platform built by developers for developers to model economics, control operations via AI-driven EMS, and monitor performance (source: energytoolbase.com). Its flagship products include ETB Developer for detailed financial analysis of project avoided costs, bill savings, and grid services; Acumen EMS™ for real-time energy optimization using machine learning to forecast and dispatch storage; ETB Monitor for tracking real-time performance and savings directly linked to modeling data; and ETB Controller for seamless solar design integration and EMS deployments (source: energytoolbase.com). These integrate into one ecosystem for end-to-end project lifecycle management, handling complex simulations like Net Energy Metering (NEM) frameworks and demand response (DR) programs (source: energytoolbase.com). Target markets center on solar and storage developers, including commercial, industrial, and residential segments, with over 1,000 organizations using it worldwide for C&I PV-only projects, standalone storage under ITC incentives, and hybrid systems in regions like California under NEM 3.0 (source: solaracademy.com).
Projects & Track Record
Energy Toolbase's track record includes deploying Acumen EMS™ at more than 90 sites across 4 countries with 60 MWh of ESS capacity as of recent updates, reflecting rapid global fleet growth (source: energytoolbase.com). Although specific project names, locations, or capacities beyond aggregate are not detailed in public sources, its software supports optimizations discussed in contexts like southern California residential storage economics and C&I impacts from NEM 3.0 (source: solaracademy.com). Ongoing expansions involve Acumen EMS™ and ETB Controller growth worldwide, alongside 2023-2024 enhancements for DR programs and NEM modeling (source: energytoolbase.com). Key clients encompass over 1,000 distributed energy organizations globally, with no specific names listed, but partnerships stem from the 2019 merger with Pason Power and backing by Pason Systems (source: energytoolbase.com).
Recent Developments
In the last two years (2024-2025, per available data up to 2024 anniversary), Energy Toolbase announced a groundbreaking simulation engine in 2023 with rapid DR program launches in early 2024 and enhanced NEM modeling across the U.S., marking milestones in comprehensive calculation capabilities for contractors and developers (source: energytoolbase.com). It celebrated its 10th anniversary in 2024, highlighting a decade of product evolution including the 2023 engine and ongoing suite growth (source: energytoolbase.com). The 2019 merger with Pason Power remains the key acquisition, with no new mergers, funding rounds, contracts won, awards, or certifications detailed in recent sources (source: energytoolbase.com).
