AB  - We analyze the electric energy usage and improve the electric demand programming of the University of the Philippines Diliman which maintains more than a hundred separate agreements for the sale of energy by Meralco to its academic buildings. Each agreement covers a unique power-meter account and obligates UP Diliman to pay a monthly electric demand charge that depends only on guaranteed minimum billing demand (GMBD) and not on actual electric demand. In 2010, the actual monthly demand in 34 of 109 accounts always stayed below their GMBD ratings. UP Diliman and Meralco reviewed the agreements and modified the GMBD ratings of 26 accounts to depend on maximum actual monthly electricity consumption in the previous billing year. The new GMBD ratings were first applied in March 2012 and the total electricity bill for the 26 accounts from March to September 2012 was approximately 30% less than what would have been paid using the original GMBD ratings for the same consumption, electricity cost and overhead charges. The 2013 bill of UP Diliman was 2.5% higher than that in 2012 while those in the 2012 and 2011 were higher by 7% and 2.8%, respectively. In contrast, relative consumption increased by 5.6%, 4% and -1.9% in 2013, 2012 and 2011, respectively. A consumption-based GMBD rating scheme is essential if the adoption of more efficient devices and energy-saving measures is to actually lower the electricity bill. Our work illustrates the benefits of accurate demand programming and meaningful public-private partnership in the operation of a public academic institution. (Author's abstract)
