Title: Feasibility of a medium-size central cogenerated energy facility. Energy management memorandum TM-82-7

Technical Report ·
OSTI ID:6603843

The thermal-economic feasibility was studied of a medium-size central cogenerated energy facility designed to serve five varied industries. Generation options included one dual-fuel diesel and one gas turbine, both with waste heat boilers, and five fired boilers. Fuels included natural gas, and for the fired-boiler cases, also low-sulphur coal and municipal refuse. The fired-boiler cogeneration systems employed back-pressure steam turbines. For coal and refuse, the option of steam only without cogeneration was also assessed. The refuse-fired cases utilized modular incinerators. The options provided for a wide range of steam and electrical capacities. Deficient steam was assumed generated independently in existing equipment. Excess electrical power over that which could be displaced was assumed sold to Commonwealth Edison Company under PURPA (Public Utility Regulatory Policies Act). The facility was assumed operated by a mutually owned corporation formed by the cogenerated power users. The economic analysis was predicated on currently applicable energy-investment tax credits and accelerated depreciation for a January 1985 startup date. Based on 100% equity financing, the results indicated that the best alternative was the modular-incinerator cogeneration system. If the system is expanded to include additional steam utilization of about 10,000 lbm/hr base load, say by incorporating a new user at the nearby vacant parcel of land requiring another 1900-ft of distribution, the case of low-sulphur-coal-fired cogeneration increases in attractiveness. In order to facilitate the raising of capital in the current recession and to increase attractiveness by providing lower interest rates, the case of 60% Industrial Development Bond (IDB) debt financing and 40% leveraged lease was also analyzed. Again the best case is the refuse-fired cogeneration plant with the existing steam users.
