Identify grid-ready, commercially viable hybrid development locations faster.
Solar and storage development is increasingly constrained by interconnection congestion, land scarcity, and capital discipline, making early, high-confidence siting decisions critical. This case study demonstrates how Enverus PRISM®, RatedPower, and Pearl Street Interconnect enable developers to rapidly identify and prioritize high-quality hybrid opportunities by unifying interconnection economics, land viability, pricing fundamentals, and competitive dynamics into a single, analytics-driven workflow.
Using Indiana as a representative market, this analysis highlights how developers can move faster and with greater certainty by focusing capital on sites with manageable upgrade costs, scalable land positions, and durable hybrid economics. The workflow surfaces locations that support near-term generation feasibility, long-term storage value, and phased hybrid development while reducing development risk and avoiding oversubscribed interconnection points.
This case study illustrates how Enverus solutions help developers identify and differentiate solar + storage siting opportunities in Indiana by integrating interconnection cost signals, land buildability, pricing dynamics, and competitive pressure into a single decision framework.
Across three evaluated locations, the analysis reveals material differences in site quality driven by:
Among the sites evaluated, Lawrence County emerges as the strongest overall opportunity, offering the lowest upgrade cost intensity, minimal queue competition, a large contiguous land position, and the highest modeled solar capacity across parcels. Cass and Hamilton Counties present viable but more specialized opportunities, each requiring more targeted hybrid or storage forward development strategies to manage competition and interconnection constraints.
Sites were evaluated using Enverus PRISM® across the following criteria:
By replacing fragmented datasets and manual screening with a unified analytics workflow, Enverus enables developers to reduce siting risk, prioritize capital efficiently, and advance projects with greater confidence earlier in the development lifecycle.
Developers pursuing utility-scale solar + storage projects in Indiana face a familiar challenge: identifying locations that simultaneously offer manageable interconnection economics, sufficient buildable land, and durable long-term value. With most attractive substations already constrained, success increasingly depends on understanding where upgrades are economically viable and how hybrid configurations can unlock value despite limited injection availability.
The goal of this analysis is to identify high-quality hybrid development zones where interconnection upgrades are justified by land scale, pricing fundamentals, and storage-driven value stacking.
Indiana is a high-value region for solar + storage development. Utilities across the state have outlined aggressive renewable and storage additions in recent Integrated Resource Plans, signaling sustained procurement needs. At the same time, the state is preparing for significant load growth from data centers, manufacturing expansions, and other power-intensive industries. For example, Duke Energy Indiana has over 5,000 MW of planned load capacity.
This convergence of renewable expansion, storage integration, and accelerating demand positions Indiana as an attractive market for developers who can move quickly and secure economically viable interconnection points. PRISM, RatedPower, and Interconnect compress months of manual screening into minutes, enabling that speed.
