Orange & Rockland County Public Utilities (ORCPU) is installing new feed-back control technology to detect and correct turbine over-speed conditions that affect the stability of its power-generation. The company estimates the equipment will provide more efficient turbine performance to the extent of saving $23,500 in year 1, and amounts increasing by $2,500 per year through the next 10-years. How much can ORCPU spend now and recover its investment in 10-years if interest is 8% per year
