What Transect is
According to its website (checked November 2026), Transect says it "helps developers identify and assess the best project sites". Its homepage headline is "Evaluate project sites with speed and confidence". The page describes expert-curated environmental, permitting and community sentiment data.
Products listed on the page include a Site Assessment platform, Community Sentiment tools, Transect Reports, Local Solar Regulations and a Services Marketplace. Industries listed include solar, energy storage, wind, data centers, EPC firms, electric utilities, environmental consultants and midstream. The page offers a login, a demo and a free mini-report made from a parcel file you upload.
What Voltane is
Voltane is a siting service for projects that need a lot of power. You tell Voltane what you need: megawatts, target energization year, region and acreage. Voltane then finds candidate sites in Texas, with a focus on ERCOT, reports on each one and returns a priced shortlist. It starts with a request form and a booked call. See Find me a site.
Behind the service is Voltane's own Texas map engine, built from public data. It reads land for distance to transmission lines and substations, interconnection queue activity, flood zones, wetlands, protected land, gas pipelines and more. Every fact carries its source and date. Every estimate is labelled as an estimate, with its range and its method. The engine is an internal tool, not a public product. Voltane shows the evidence the engine produced for each site in the report.
Some limits, stated plainly. Voltane's capacity signal is a proxy built from distance to transmission and queue competition. It is never available MW at a substation. Voltane does not publish landowner names. Its results are screening only, not a site suitability determination. A second service, Analyze my site, for a site you already have in the contiguous United States, is available by request; online ordering is not open yet.
How they differ
| Question | Transect | Voltane |
|---|---|---|
| Model | Site assessment platform with reports and a services marketplace, per its site | Done-for-you engagement that starts with a request form and a call |
| What you get | Environmental, permitting and community sentiment data and reports, per its site | A priced shortlist of candidate sites, with a sourced report on each |
| Coverage | Not stated on its homepage. See their site | Texas, with a focus on ERCOT. Analyze my site takes sites across the contiguous United States, by request |
| Who does the work | See their site | Voltane, using its internal map engine |
The two answer different first questions. Voltane starts from power: where a load or a generator could connect, how long connections have taken for similar projects, and what the land looks like. Transect, from what its site says, centers on environmental, permitting and community review of a site. Voltane does screen mapped flood zones, wetlands and protected land, but it does not replace an environmental review.
Which fits when
Transect may fit when you already have sites in mind and need environmental and permitting diligence on them.
Voltane may fit when you do not have the site yet and need a power-first shortlist in Texas.
The two can work in sequence: a power-first shortlist, then deeper environmental and permitting review of the sites you keep.
Product details change. Check each company's own site before deciding. All trademarks belong to their owners.
Questions people ask
Does Voltane do environmental due diligence?
No. Voltane screens against mapped flood zones, wetlands and protected land from public sources. That is a first pass. Field delineation, species and cultural reviews need specialists.
Is Transect a Voltane competitor?
They overlap at the early screening stage but focus on different questions. Transect describes environmental, permitting and community data. Voltane runs a power-first site search in Texas as a service.
