What it is

What is the Global Battery Storage Projects Database?

A market intelligence platform tracking grid-scale battery storage projects worldwide, from the first interconnection request and capacity market prequalification through permitting, integrator selection, cell procurement, construction, commissioning, and augmentation. Every record carries verified investment values, power and energy capacity, chemistry, timelines, stakeholders, tenders, and decision-maker contacts.

Integrators, cell and inverter suppliers, EPCs and utilities use it to find storage sites while procurement is still open, match duration and chemistry to their product, and follow each project to energisation.

Find projects first

Coverage begins with interconnection requests, capacity market registrations, utility procurement notices and planning filings, read in the local language before a project is announced.

Know every stakeholder

Developer, owner, system integrator, EPC, and cell, inverter and transformer suppliers are mapped to each project with verified contacts.

Act at the right stage

Each project carries its stage, from grid application and capacity award through financing and construction to energisation, and an alert fires when a watched project clears its next milestone.

Prove it before you bid

Power and energy ratings, duration and supply awards are reconciled against two independent sources and cited, with a last-verified date, so a rating can be checked before it goes into a proposal.

What the Battery Storage Company Data Shows

Blackridge tracks 3,157 owners and developers across the battery storage pipeline. The 25 most active hold 379 projects between them, led by Innova Renewables Limited (28), Tempus Power management LLC (25) and Vesper Energy Development LLC (25).

The five busiest account for 32% of the projects held by the top 25, so the pipeline is spread across a broad field of builders rather than a few dominant ones.

Of the top 25, 18 act as owners only and 7 both own and develop.

Across their projects, 14% are already past contract award. ACEnergy Pty Ltd has the most in that phase, with 16 projects at award or under construction.

Full profiles for all 3,157 companies, with their project lists, contract awards and verified contacts, are in the database.

Project Density by Region

Where the tracked pipeline actually sits. Counts come straight from the live database and are compared against the busiest region, not against a total: the regions overlap, so they are never added together.

Bars are scaled to the busiest region. A project in a country belonging to more than one grouping is counted in each, so these figures are not additive.

Battery Storage Pipeline by Stage and Region

Of the 4,675 upcoming battery storage projects tracked, 16% are at contract award, pre-construction or under construction, 82% are in study, planning or design and 2% have only been announced. Planning is the largest single stage, with 3,710 projects.

The 738 projects past contract award carry $105 billion in capital expenditure, the part of the pipeline where equipment and construction packages are being let now.

Projects past award average $143 million each, against $389 million for those still in study, planning or design.

Europe holds the most tracked projects, 2,828 or 60% of the pipeline, followed by North America (1,340) and Asia-Pacific (379).

By announced investment, Europe leads with $1.26 trillion and also has the largest average ticket, $444 million per project.

Construction is furthest along in Africa, where 71% of tracked projects are past contract award, compared with 11% in North America.

FAQ

Questions Battery Storage Teams Ask

About the database

A continuously updated database of grid-scale battery storage projects in 60 countries, covering queue entry, permitting, procurement, construction, and commissioning, researched in local languages with verified developer and integrator contacts.

Coverage and data

60 countries. Coverage is deepest in China, the United States, Australia, the United Kingdom, and Western Europe, but the database follows the pipeline into every market where new storage is being procured, including Africa and Latin America.
Tracked planned capacity runs to hundreds of gigawatt hours across all stages, with the largest single arrays now exceeding 6 GWh. The database records MW and MWh per project so you can size any market precisely rather than relying on headline estimates.
Yes. Cell chemistry, system duration, augmentation schedule, and warranty terms are captured per record, so you can filter to the exact configuration your product or model addresses.

Market fundamentals

Most queue positions are speculative. Land rights, revenue contracts, and cell allocation each remove a large share of applications, which is why raw queue volumes overstate the real pipeline by a wide margin and stage-tagged data matters more here than in any other asset class.

Data quality and methodology

Power and energy ratings are captured separately per phase, and capital expenditure is converted to USD with the local-currency figure and conversion date retained. That makes an array in Chile directly comparable to one in Germany.

Plans and getting started

Request a trial and get full platform access for a limited period with no card required upfront. You can search, filter, and export project data before committing to a plan.
Immediately after your trial or subscription is activated. There is no onboarding delay or implementation project. Log in, filter to your target countries or stages, and start working the pipeline the same day.
