Voltane vs PVcase Prospect: Site Search

What PVcase Prospect is

According to its website (checked November 2026), PVcase describes Prospect as an "All-in-one solution for early-stage renewable development". The product page says teams can target, analyze and de-risk sites around points of interconnection.

Features listed on the page include automated parcel search, buildable area analysis, constraint maps, flood risk analysis and land data such as ownership and zoning. It also lists interconnection and market data, including locational marginal prices, power-flow studies for injection and offtake capacity, and a portfolio view. The page offers a demo request, a sign-in link and a pricing plans page.

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.

From what its page says, Prospect is software for renewable development teams to run their own site search. Voltane runs the search for you and reports back. Voltane's lead use is large loads and gas-to-power in ERCOT, with solar and storage screened on the same engine. Voltane does not run power-flow studies. Its grid signal is a proxy, not a capacity figure.

Which fits when

PVcase Prospect may fit when you run an ongoing renewable pipeline and want your own team working in software every day.

Voltane may fit when you need a Texas shortlist for one requirement and want the work done for you, with the method shown.

Questions people ask

Does Voltane run power-flow studies?

No. Voltane screens with public data and labels its grid signal as a proxy. Capacity questions are answered by ERCOT and the transmission owner through studies.

Is Voltane only for data centers?

No. Data center and gas-to-power sites lead, and the same Texas engine screens solar, storage and hybrid sites.
