Smarter Way to Develop Projects

Minimize Risk and Save on Costs

Strategically target sites with a path to power and eliminate large, unexpected costs on bad sites and wasted due diligence.

Replace 3-5 Tools with One Platform

Integrate grid, market, infrastructure, and land analysis to avoid silos and costly consultant studies.

Cut High-Risk Sites Fast

Screen points of interconnection (POIs) in minutes and eliminate weak interconnection candidates before they consume months of diligence and budget.

Scale with Repeatable and Data-Driven Process

Create consistent and scalable processes for confident, consistent decisions every time.

Trusted ISO-Aligned Grid Modeling for Confident Decisions

Experienced transmission planning engineers perform system-wide N‑1 power-flow studies based on the latest grid-operator base cases. You get ISO/RTO-aligned studies that reflect how each region is actually evaluated — combining queue data, transmission upgrades, and retirements to estimate injection and withdrawal capacity, identify constraints, and clarify upgrade cost exposure across all regions, including SERC and WECC.

Why Development Teams Choose PVcase Prospect

Make Go/No-Go Decisions in Minutes

Evaluate injection and offtake capacity, upgrade exposure, and potential interconnection risks instantly.

Keep Projects Within Upgrade Budget

Identify points of interconnection with sufficient injection or withdrawal capacity based on target project size and within upgrade budget (allocated costs or total upgrade costs).

Right-Size Your Project Before You Trigger Costs

Identify the sweet spot where project scale meets peak profitability. Fine-tune generator, battery storage, or data center campus project size (MW) to avoid triggering incremental grid upgrade costs.

See NRIS & ERIS Studies Across the U.S.

Frequently Asked Questions

What makes PVcase stand out from similar competitors?

PVcase Prospect sets the standard for capacity analysis with ISO/RTO-aligned, power-flow modeling built directly into a complete site selection and due diligence platform. Using CEII base cases, interconnection queue data, contingency files, and each operator’s study assumptions, you can quantify injection and withdrawal (offtake) capacity, identify constraints, and estimate network upgrade cost exposure — before you commit time and capital.

Unlike solutions that rely on simplified proxies or keep grid analysis siloed from the rest of development, PVcase Prospect mirrors the process you’ll face in the queue — so your site decisions are based on engineering-grade evidence, not marketing-grade estimates.

What is the primary difference between PVcase Prospect and a standalone grid analysis platform?

PVcase Prospect natively integrates high-quality, consultant-grade grid modeling (including injection/offtake capacity and allocated upgrade costs) directly into a platform with dynamic land and market analysis. This single-source-of-truth approach enables you to make holistic, de-risked decisions at scale — so you don’t waste months on the wrong site only to hit interconnection surprises later.

Standalone grid platforms can deliver high-quality, power flow–based N‑1 interconnection analysis — but the insights are often siloed and built for transmission engineers. That makes it hard to connect grid results to market and land feasibility, forcing teams into manual cross-referencing across multiple tools that doesn’t scale.

Do you provide interconnection studies for transmission lines?

Yes, PVcase Prospect provides interconnection studies for transmission lines. In fact, we are the only software provider to offer the same high-quality modeling for transmission lines and not just substation buses. Many renewable energy and data center developers need to evaluate line capacity and upgrade costs since ideal land is already taken around good substations. This is why we put in the extra work to do the modeling for transmission lines, too.

How accurately does PVcase Prospect address interconnection risk and upgrade costs?

We work with a leading power-flow modeling partner to deliver trusted grid studies that help you understand interconnection risk (and opportunity) early. Using the grid operator’s latest base case, we run full N‑1 power-flow simulations — aligned with each ISO/RTO’s study approach — then layer in queue data, planned transmission upgrades, and retirements to estimate capacity, constraints, and likely upgrade cost impacts.

No model can predict capacity perfectly, but this gives you the clearest picture available at the start — so you can focus on POIs with enough headroom, anticipate constraints, and evaluate upgrade cost exposure before you enter the queue.

What kind of projects are PVcase Prospect’s interconnection studies & grid analysis designed for?

PVcase Prospect’s grid analysis is built for utility-scale projects that need accurate interconnection modeling—solar, wind, and BESS, as well as data centers and other large power consumers. It models both injection capacity (often called ATC) and withdrawal/offtake capacity, and estimates allocated upgrade costs, so teams can make informed siting decisions with clearer grid and cost visibility.

What’s PVcase Prospect’s coverage for grid data? Are there any areas you don’t have data for?

PVcase Prospect offers comprehensive nationwide coverage in the U.S., including both deregulated and regulated regions (including WECC, TVA, the Southeast, and other hard-to-obtain regions).

Does PVcase Prospect truly replace other tools in my workflow?

Yes, PVcase Prospect replaces disjointed tools and point solutions across the entire early-stage project development workflow. The most common reason developers and engineers choose PVcase Prospect is that they want an all-in-one solution for early-stage project development. Developers leveraging PVcase typically replace 3–5 siloed tools — including separate GIS/land tools, grid analysis providers (or consultants), market data, and early-stage layout tools.

Does PVcase Prospect model large load requests?

Hyperscale load requests are so new that there’s no standardized “load queue” like there is for generation — utilities don’t publish that data, so nobody can model it. Once a load is approved, it shows up in future base cases, so we mirror the ISO/RTO approach and include only approved load interconnections to match what you’ll see in-queue.
