Industrial CHP installations achieve overall system efficiencies exceeding 75%, qualifying for Section 48 ITC and 5-year MACRS accelerated depreciation. By recycling prime mover exhaust into 150 PSIG plant steam, facilities hedge against peak grid volatility while eliminating carbon emissions from aging auxiliary gas boilers.
