【 摘 要 】

As of September 28, 2001, all the major project tasks have been completed. A presentation was given to the North Dakota State Penitentiary (NDSP) and the North Dakota Division of Community Services (DCS). In general, the feasibility study has resulted in the following conclusions: (1) Municipal wood resources are sufficient to support cofiring at the NDSP. (2) Steps have been taken to address all potential fuel-handling issues with the feed system design, and the design is cost-effective. (3) Fireside issues of cofiring municipal wood with coal are not of significant concern. In general, the addition of wood will improve the baseline performance of lignite coal. (4) The energy production strategy must include cogeneration using steam turbines. (5) Environmental permitting issues are small and do not affect economics. (6) The base-case economic scenario provides for a 15-year payback of a 20-year municipal bond and does not include the broader community benefits that can be realized.
