5 Current Results and Challenges Tp- 10,000 Prgram results: Based n a gvernment evalua;n f mre than 16,000 industrial enterprises Saved 170 Mtce as f 2012, r 68% f the ttal target LBNL Study n Energy Audi;ng in China Assessed China s energy audi;ng prac;ces based n researches n na;nal plicies and a series f in- persn interviews in 6 prvinces/ci;es. Key findings were iden;fied t further imprve the prac;ces f industrial energy audi;ng in China, such as the need fr: Effec;ve assessment tls Capacity and prper training fr energy audits 5

10 Case study results: energy- savings by areas a Assuming plant s pera;ng hurs per year are equal t 8,400 hurs. b 1 kgce= 29,300 kj r 29.3 MJ net hea;ng value. c 1 Metric tn f "standard" cal equivalent tce = 29.3 GJ. d The percent energy savings is the ra; between saved energy and current level f ttal grss heat input fr the prcess hea;ng system. Actual energy savings are less than the sum f all energy savings frm each individual measures. Actual energy savings depend n implementa;n rates f recmmended measures, as well as the changes in grss heat input. e Cal reduc;n is es;mated based n the cal hea;ng value f 6,000 kcal/kg, r 25,121 kj/kg, as reprted by the steel mill. f Cst saving is es;mated based n purchased cal cst f 500 RMB per tnne, as reprted by the steel mill. 10

11 Cnclusins At the enterprises level: Significant energy- savings pprtuni;es exist Pten;ally very large energy, envirnment, and ecnmical impacts Plicy pprtuni;es t imprve Tp- 10,000 prgram Strng lcal demand fr qualified energy auditrs and technical energy assessments Needs fr capacity building in terms f technical knw- hw and standardized prac;ces Needs fr incen;ves t cnduct nn- prject based energy- saving ac;vi;es, such as energy assessments, energy management 11
