Distributed Generation: Hype vs. Hope
their customers. But over-selling DG as a universal alternative is dangerous, since the greater the hyperbole, the more likely that expectations for DG will be unmet. Such a situation could result in wholesale rejection of DG, even when its benefits are clear.
We believe the best approach for utilities, regulators, and customers will be to identify those situations where DG applications can have the most value and focus development efforts there. Our work has shown that, when load uncertainty is great but the overall trend in load growth is relatively small, DG is likely to have the greatest benefits. In this era of increasing competition and greater energy market volatility, we expect those conditions increasingly to be found.

- Oddly enough, in the 2002 legislative session, a bill was introduced that would defined some fossil-fueled DG applications as "renewable energy" sources.
- The approach we use is called "dynamic programming." It is a mathematical optimization technique that forms the basis for the solution of virtually all dynamic investment problems, and which is often used in "real options" analysis.
