DSM Planning & Evaluation Minimize

The utility industry has changed significantly over the past 10 years. Wholesale deregulation is now common. RTO’s are emerging as successful and likely permanent, entities. Direct load control programs continue to grow as a cost-effective alternative to plant, or physical generation. Customer siting of micro generation units and other distributed generation is creeping along at a slow, but non-zero pace. Environmental compliance, natural gas resource availability issues, electric wholesale price volatility, and infrastructure reliability concerns, among others, represent some of the increasing complexities that today’s utilities face. To respond to these complexities, today’s utility planners need better, more robust analytical tools to cope. Today’s planners need to look beyond traditional “system lambda” production costs (versus forward, openly traded markets) and consider the impacts of using traditional average costs for their energy-related decision making.

Demand Side Management Option Risk Evaluator (DSMoreTM) is a powerful financial analysis tool designed to evaluate the costs, benefits, and risks of demand side management (DSM) programs and services. The power of DSMore lies in its ability to process millions of calculations within seconds, resulting in thousands of cost effectiveness results that vary with weather and/or market prices. By viewing DSM performance and cost effectiveness over a wide variety of conditions, managers and regulators are in a better position to measure the risks and benefits of employing DSM measures versus traditional generation capacity additions.

DSMore provides all of the familiar cost effectiveness test results, including Utility Cost Test, Total Resource Cost Test, Ratepayer Impact Measure Test, and Societal Test. Moreover, these test results are provided for various weather conditions, including weather normal, and under a number of wholesale market conditions. DSM measures perform better during higher priced wholesale markets and more extreme weather. In fact, given that these two environmental forces tend to occur at the same time, the added boost in value that accrues to DSM avoided cost has a natural upward skew in value By viewing numerous test results, the upward skew in DSM cost effectiveness becomes apparent. This added option value of DSM measures in the face of high wholesale market price conditions indicates the extent to which some DSM measures are undervalued by using more traditional single scenario methods, such as DSManager. Interestingly, a traditional DSManager analysis is actually one of the several thousand test analyses that are conducted by DSMore during each program evaluation

Users and analysts interface with the complex programming power of DSMore through Excel. If you can use Excel, you can use DSMore. This means that the power of DSMore is available to more than just technical users, statisticians, economists, or engineers. One worksheet holds your DSM program inputs and the remaining worksheets provided all your requested output. Changes are as simple as cell changes within Excel, and ad hoc additions to your inputs or outputs can be done within the same Excel file, if necessary.


  • Evaluates thousands of DSM cost effectiveness scenarios over a range of weather and market price conditions.
  • Allows user to change DSM program parameters and reevaluate in seconds.
  • Employs real customer-specific hourly load shapes in calculations.
  • Provides equivalent DSManager results for comparison.
  • Familiar and easy-to-use Excel interface.
