# What does a data room for a renewable energy or infrastructure deal cost?

Renewable energy and infrastructure deals — portfolio sales and tax equity financings — are diligenced project by project: offtake and interconnection agreements, land rights, and independent engineer and energy yield reports.

Below: the transactions that use a data room in this sector and what goes into the room, in the words of regulators and advisers; what a room of that kind costs at every vendor that publishes prices; and the vendors whose own website names the sector.

## Transactions that use a data room

- “Prior to closing a tax equity investment, the bank performs due diligence similar to a loan closing.” [American Council on Renewable Energy 2026-09-22](https://acore.org/resources/the-risk-profile-of-renewable-energy-tax-equity-investments/)

- “to review due diligence materials for tax equity financings in all fifty states.” [Foley & Lardner LLP 2026-09-22](https://www.foley.com/sectors/energy/renewables/tax-equity/)

## What goes into the room

- “The tax equity investor will review and comment on project contracts – including the PPA, interconnection agreements, EPC contracts, site lease agreements, O&M agreements, and other key project documents.” [American Council on Renewable Energy 2026-09-22](https://acore.org/resources/the-risk-profile-of-renewable-energy-tax-equity-investments/)

- “the tax equity investor and project engage an independent engineer and, in the case of an ITC, an appraiser to assess the value of the property.” [American Council on Renewable Energy 2026-09-22](https://acore.org/resources/the-risk-profile-of-renewable-energy-tax-equity-investments/)

## Rules and standards that shape the room

- IEC 61400-12-1 (wind power performance measurement): “IEC 61400-12-1:2022 specifies a procedure for measuring the power performance characteristics of” [International Electrotechnical Commission 2026-09-22](https://webstore.iec.ch/en/publication/68499)

- IEC/UL 61730 (PV module safety): “UL Solutions supports projects aligned to PV safety frameworks such as IEC/UL 61730 for modules” [UL Solutions 2026-09-22](https://www.ul.com/services/solar-and-wind-project-due-diligence-services)

The descriptions above are quoted from regulators, standard setters, law and accounting firms and industry bodies, with a link to each; none comes from a data room vendor. They describe common practice and are not a complete diligence list or legal advice for any transaction.

## What a renewable energy or infrastructure deal data room costs

Totals use the lowest listed plan selected under the [storage and admin-seat rules](https://dealcostindex.com/vdr.html#billing-basis), on monthly billing where the vendor offers it. Vendors are listed alphabetically; the order is not a ranking. Plans are not matched on features.

The room inputs are illustrative and were fixed before any total was computed; no published source gives typical room sizes for this sector, and your room will differ. Prices are as published by each vendor on the date shown. Fit is decided on stated storage and admin seats only; security, features, support and suitability for any transaction are not assessed, and nothing here is a recommendation of any vendor.
