Solar developers in the PJM region, particularly in Pennsylvania, West Virginia, and Ohio, often encounter land with a complex history of mineral development. This history can significantly impact solar projects, from site planning to obtaining title insurance coverage. Understanding the interplay between surface and subsurface rights is crucial for developers to protect their interests and ensure project viability. Diligent site planning and careful review of mineral title research can go a long way in preventing worst case scenarios and mitigating risk.
