Everything a storage team needs to develop and deliver BESS projects
See every storage project in one portfolio view
Run your whole pipeline of battery storage projects, from early-stage development sites to EPC and commissioning, in a single portfolio view. Track milestones, capacity, budget and grid-connection status side by side, so you can spot which sites are slipping and rebalance resources before a delay spreads across the fleet.
Fund the strongest storage sites first
Score and rank storage opportunities against your own criteria: revenue stacking potential, grid readiness, permitting risk, capital required and strategic fit. Instead of building whatever gets the loudest support, you back the sites with the best return and lowest risk, and defend every go/no-go decision with a transparent, repeatable model.
Control every development gate with formal approvals
Run each storage project through defined gates: land control, permitting, interconnection, final investment decision and notice to proceed. A project only advances once the required sign-offs are in, so capital is never committed to a site that has not cleared its stage, and every approval is logged with who decided and when.
Plan permitting, procurement and grid connection
Build multi-year schedules with unlimited task depth: permitting, interconnection studies, procurement of batteries and inverters, civil works, installation and commissioning. When one date moves, the Gantt shows the knock-on effect across the whole build, so you can rebook crews and equipment before the delays collide.
Keep storage CAPEX under control
Plan storage CAPEX from both cost and revenue sides, with budget items, from battery modules and inverters to balance of plant and interconnection, linked to schedule tasks so cash flow always matches the build plan. Track committed versus actual spend per project and across the portfolio, and see overruns forming while there is still time to react.
Operate and expand your fleet
Manage the steady flow of augmentation, retrofits and warranty works across an operating storage fleet with the same discipline you use for greenfield builds: recurring templates, clear owners and full cost visibility.
Explore recurring projects
For development and EPC teams
Development and EPC teams work from one shared schedule, see how permitting, procurement and construction depend on each other, and always know which task and which grid milestone comes next.
For project teams
For the PMO and management
The PMO gets one view of every storage project in the portfolio, with status, capacity, cost and risk in the same place, ready for investment committees and board reporting without manual spreadsheet work.

Project reviews
Catch a slipping storage project before it derails the portfolio
Run regular project reviews across your storage pipeline and walk into each one with the numbers already there: milestones hit and missed, budget against plan, open risks and the next grid date. Every review is captured in FlexiProject, so decisions, actions and owners carry forward instead of living in meeting notes, and your investment committee sees the same status the project team does.
project attributes
Capture the storage project details that standard fields miss
Storage projects carry data that generic project fields never hold: installed power in MW and energy capacity in MWh, cell chemistry, point of interconnection, expected commercial operation date, augmentation schedule and revenue model. In FlexiProject you define these attributes once, then filter, group and report your whole portfolio by them, so a board pack by technology or grid region is a click, not a week of spreadsheet work.

Frequently asked questions
What is the best energy storage project management software?
FlexiProject is energy storage project management software built for how BESS projects actually run: one system for the whole pipeline, from site development, permitting and interconnection through EPC, commissioning and handover. It combines portfolio scoring, stage-gate approvals, multi-year Gantt scheduling and CAPEX control, so developers, EPC teams and the PMO share one live plan. It suits utility-scale, C&I and behind-the-meter storage developers who run several projects at once and need portfolio-level visibility and control.
How does FlexiProject support the BESS development lifecycle?
You model each phase of a storage project as a stage gate: land control, permitting, grid interconnection, final investment decision, notice to proceed, construction, commissioning and handover. A project only moves forward once the required approvals are in, and every gate is logged with the decision, the approver and the date. The schedule links each phase to its tasks, milestones and budget, so you always see where a project sits in the lifecycle and what has to happen next.
Can it manage a portfolio of storage projects at once?
Yes. FlexiProject is portfolio-first. Every storage project appears in one portfolio view with its status, capacity, milestones, budget, risks and grid-connection stage side by side. You can group and filter by technology, region, stage or revenue model, and roll costs and risks up to portfolio level. Project scoring helps you rank sites and decide which ones to fund first, so limited capital and resources go to the strongest opportunities.
How does FlexiProject help control storage project costs?
Budgets are planned from both the cost and the revenue side, with items such as battery modules, inverters, balance of plant, civil works and interconnection linked directly to schedule tasks, so cash flow follows the build plan. FlexiProject tracks committed versus actual spend per project and across the portfolio, and forecasts final cost as the project progresses. Overruns become visible early, while there is still room to renegotiate, resequence or escalate, instead of at project close.
Is FlexiProject cloud-based and available in other languages?
Yes. FlexiProject runs fully in the cloud, with no local install, and comes with an interface in 28 languages and product documentation in 11. A mobile app lets team members update tasks and statuses, add comments and attach files from the field, which is useful when construction and commissioning crews are on site rather than at a desk. A 30-day free trial with full access lets you evaluate it on a real storage project before you commit.
