Paper features the SUR industrial/commercial demand-charge equations as its contribution and benchmarks the industrial energy elasticity against the literature; residential is reported 'for completeness'. || 'Mount, Chapman, and Tyrell (1973), for instance, estimate the industrial energy elasticity to be about -1.8... the similar elasticity in this study is the sum of the marginal energy and demand change elasticity or -2.68.' (p.131); 'For completeness, a residential energy demand equation is reported.' (p.128)
