Doral has secured essential construction permits to begin the second phase of its massive solar project in Indiana. This expansion will add 1,100 megawatts of capacity to the facility.
Why it matters
The project supports Indiana clean energy goals by integrating solar generation with traditional agricultural practices, such as livestock grazing to manage vegetation. It utilizes agrivoltaic systems to maximize land utility while feeding energy into the PJM grid.
The phase two expansion costs between NIS 2.5 billion and NIS 3 billion, with annual revenue projected at NIS 350 million. The entire site spans 80,000 dunams of land.
The players
Doral
Doral is an energy firm specializing in the development of renewable energy infrastructure and solar projects.
Bank of America
Bank of America is a multinational financial services corporation acting as a tax partner for the solar development.
Truist Bank
Truist Bank is a financial services holding company that is serving as a tax partner for the project.
The details
The project employs agrivoltaic methods, where livestock grazing maintains vegetation around panels to ensure sunlight exposure. Bank of America and Truist Bank are serving as tax partners to help facilitate the development.
Timeline
2029 is the scheduled completion year for the entire 2,700-megawatt solar farm.
Market Landscape
This project follows the pattern of large-scale renewable developments designed to feed electricity directly into the PJM grid. By securing these permits, Doral strengthens its position in the competitive U.S. Midwest energy sector.
Landowners participating in the project receive fixed payments for the use of their property for solar arrays. The expansion contributes to regional energy goals without requiring new energy storage capabilities on-site.
The takeaway
Large-scale agrivoltaic projects demonstrate how industrial energy generation can coexist with agricultural land use. By grazing livestock among solar panels, developers can effectively maintain infrastructure while supporting local farming economies.
