PSE and G cogeneration evaluation

Technical Report ·
OSTI ID:5011706

In order to foster all possible methods of conserving energy within New Jersey and to provide the lowest possible energy costs to its customers, Public Service Electric and Gas Company (PSE and G) investigated the potential for cogeneration within the PSE and G electrical territory. Cogeneration is defined in this report as the production of industrial process steam as a by-product of electric generation located at the industrial plant. The cogeneration evaluation uses a ''total system'' in which the total costs of PSE and G and the customer are determined. Two scenarios were compared: PSE and G system expansion based on the potential cogeneration displacing planned nuclear units; and the presently planned PSE and G system expansion. ''Site specific'' studies were evaluated for the 18 PSE and G customers with a minimum steam usage of 50,000 lbs/hr for 5000 hrs or more who were the best prospects for cogeneration. This study concluded that: cogeneration is a theoretical alternative for 18 customers in the PSE and G electric territory with a total potential of about 430 MW of generating capacity; cogeneration is not an economic alternate to nuclear capacity, involving a present worth penalty of $400 million for 430 MW; of the 18 customers, 12 totaling 300 MW ma have the potential by a very small margin for providing cogeneration as an economic electric capacity addition on the PSE and G system; and cogeneration would significantly increase America's dependence on oil which is currently counter to national policy.
