GAO-16-436R 1 (2016-02-19)

handle is hein.gao/gaobadryf0001 and id is 1 raw text is: GA U.S. GOVERNMENT ACCOUNTABILITY OFFICE 441 G St. N.W. Washington, DC 20548 B-327785 February 19, 2016 The Honorable Lisa Murkowski Chairman The Honorable Maria Cantwell Ranking Member Committee on Energy and Natural Resources United States Senate The Honorable Fred Upton Chairman The Honorable Frank Pallone, Jr. Ranking Member Committee on Energy and Commerce House of Representatives Subject: Department of Energy: Energy Conservation Program: Energy Conservation Standards for Pumps Pursuant to section 801 (a)(2)(A) of title 5, United States Code, this is our report on a major rule promulgated by the Department of Energy (DOE) entitled Energy Conservation Program: Energy Conservation Standards for Pumps (RIN: 1904-AC54). We received the rule on February 4, 2016. It was published in the Federal Register as a final rule on January 26, 2016. 81 Fed. Reg. 4368. The final rule adopts new energy conservation standards for pumps. DOE determined that new energy conservation standards for pumps would result in significant conservation of energy and are technologically feasible and economically justified. The new standards are expressed as a Pump Energy Index (PEI) and vary by equipment class. Under the adopted standards, a pump model would be compliant if its PEI rating is less than or equal to the adopted standard. DOE states that a PEI is defined as the pump efficiency rating (PER) for a given pump model (at full impeller diameter), divided by a calculated minimally compliant PER for the given pump model. PER is defined as a weighted average of the electric input power supplied to the pump over a specified load profile, represented in units of horsepower. A value of PEI greater than 1.00 would indicate that the pump does not comply with DOE's energy conservation standard, while a value less than 1.00 would indicate that the pump is more efficient than the standard requires. According to DOE, the minimally compliant PER is unique to each pump model and is a function of specific speed (a dimensionless quantity describing the geometry of the pump); flow at best efficiency point (BEP); and a specified C-value. A C-value is the translational component of a three-dimensional polynomial equation that describes the attainable hydraulic efficiency of pumps as a function of flow at BEP, specific speed, and C-value.
