Public utilities: public service commission; calculation of costs of renewable energy; provide for. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 6y.

SB 369 requires Michigan's Public Service Commission to create an online tool by December 31, 2026, that calculates the full lifetime cost of renewable energy projects for customers. The tool must include construction costs (like site prep, materials, grid connection) and end-of-life costs (decommissioning, disposal, site cleanup) for renewable energy systems. It directly affects utility customers by making these costs transparent over the system's operating lifetime. The bill mandates this calculation under Michigan's existing renewable energy framework without changing current energy policies.
