The Dunsky team recently completed a series of potential studies, and has recently launched a series of new ones, to define what can be achieved – in energy, demand and carbon savings – and at what cost.
In Iowa, where utilities have for years pursued significant savings opportunities, the Dunsky study is now public. In it, we found continued, cost-effective savings opportunities across all sectors, markets and end-uses. For electricity, we found 10-year cost-effective savings equivalent to 22% of total loads, roughly three-quarters of which could be achieved under the most aggressive program scenarios. For natural gas, 19% of sales could theoretically be reduced cost-effectively, with just over 3/4 of that considered achievable within a decade.
While most such studies focus on incentive programs, this study innovated by examining both incentive and financing mechanisms. We found that a combination of incentives and financing could be used to achieve savings at significantly lower cost than through incentives alone.
Dunsky’s user-friendly model will now be used by our clients – MidAmerican, Alliant and Black Hills Energy – to inform the program strategies they will use to continue to help lower their customers’ bills while cost-effectively contributing to the state’s energy and environmental goals.
We look forward to reporting on similar projects underway in Massachusetts, New York, Québec and beyond.
