Part E - A Comparison Of Electric Utility and NUG Generating Data

Louisiana Electric Utility and NUG Generation Capacity and Electric Generation

Table X presents 1994 data on generating capacity, electric generation, and capacity use for Louisiana electric utilities and Louisiana NUGs. As discussed previously in this report, the NUGs in Louisiana, primarily industrial cogenerators, have historically generated a substantial fraction of total power generated in the state. In 1994, the number of generating units in Louisiana was 175. The electric utilities operated 109 (62.29%) of these units while the NUGs operated 66 (37.71%) units. Generating capacity in the state totaled 19,672 MW or 172,326 million KWH per year. Of this capacity the electric utilities held 16,672 MW or 147,807 million KWH per year (85.7%) while the NUGs held 2,799 MW or 24,519 million KWH per year (14.23%). Estimated total generation of electricity totaled 77,974 million KWH in 1994 for a capacity use level of 45.25%. In that year, Louisiana electric utilities generated 60,169 million KWH (77.17%) for a capacity use percentage of 40.71%. During the same period Louisiana NUGs generated 17,805 million KWH (22.83%) producing 72.62% of possible capacity.

Sales, Transfers, and Consumption of Electricity in Louisiana by Electric Utilities and Industrial NUGs

Data comparing 1994 sales, transfers, and consumption of electricity by electric utilities and NUGs in Louisiana are presented in Table XI. As stated in the paragraph above, reported electric utility generation was 77.17% of an estimated 77,974 million KWH state total while EEI estimated NUG generation produced the remaining 22.83%. Electric utility delivery of electricity to ultimate consumers totaled 69,920 million KWH or 79.95% of total Louisiana consumption, 87,450 million KWH. After adjusting utility and NUG generation figures by 274.45 million KWH (0.31% ot total consumption) representing sales from NUGs to utilities, the utilities are estimated to have made combined out of state purchases and transfers from Louisiana utility generating facilities in Texas of 9,467.7 million KWH (10.83% of total state consumption). Net internal 1994 consumption of self-generated electric power by industrial NUGs in Louisiana was 17,530.7 million KWH (20.05% of total state consumption). This internally generated industrial consumption figure combined with the 29,867 million KWH (34.15% of total state consumption) delivered to industrials by Louisiana electric utilities implies that 1994 industrial consumption of electricity was over half (54.2%) of total electricity consumed in the state. Of total 1994 Louisiana industrial consumption of electricity, the electric utility / NUG split was 63.01% / 36.99%.
