How do you convince a CIO of a utility to care about energy efficiency?

5 Answers

This is a bit of a trick question. CIO really does NOT care about efficiency because it means less revenue. However, some states are mandating efficiency programs and so the CIO wants to do this as cost effectively as possible. Some utilities in some states also face competition for energy consumption, so a customer engagement program that makes consumers feel good about their utility will help with rate approvals and satisfaction ratings, which will boost the bottom line overall.

He cares because if he can lower the system peak number, he can lesson the amount of spinning reserves he must have in place, whixh in effect is stranded capital.

CIO cares since as a company executive he needs to work with his customers (operating unit executives) to cut costs and increase revenues. By providing a solution that mines data to assist customer to save energry usage - the CIO is prioviding a solution for the utility to flatten its energy demand curve.
