A Case Study: Managing Cogeneration Systems

Abstract

ABSTRACT The small cogeneration plant manager faces new challenges in that the cost of natural gas and electricity vary as never before. Time-of-day tariffs and deregulated markets require frequent balancing of thermal and electric costs and benefits. A simplified method allows a graphical solution that determines profitability based on fuel and electric rates. Whether this more frequent review is monthly, daily, or hourly depends on local conditions.
