In summary , the total time needed to complete the design , installation , and testing at a typical 500 MWe facility with one FGD unit is 27 months , 32 months at a facility with two boilers being served by a single absorber module , and approximately 36 months at a facility with three absorber modules ( six boiler units ) .
To summarize , it took 27 months to complete the design in that particular way- otherwise 36 .
