    Abstract

    The technical aspects of small-scale cogeneration plants were outlined. The parameters affecting their economy were discussed. The economics of both SCP (Small Cogeneration Plants 1 - 20 MW(e) and MCP (Mini Cogeneration Plants < 1 MW(e)) was estimated using tariffs and costs valid in Finland. Two typical case studies were also considered. The result has demonstrated that both (SCP) Small Cogeneration Plants (1 - 20 MWe) and (MCP) Mini Cogeneration Plants (less than 1 MWe) are generally competitive in comparison to other conventional methods of producing electricity and heat. In case of SCP the electricity tariff in force is the factor which has the most pronounced role in their economics. This is also true in case of MCP, however, the district heat tariff and the type of fuel used in the boiler have similar pronounced effects in case of MCP. Upon escalation of oil proces the competitiveness of SCP & MCP using natural gas improves.
