Valuing Storage
3 broad categories Reliability
Backup or reserves
Power quality Frequency control, voltage control, VAR support
Reduces cost Arbitrage, peak shaving, eliminate curtailments,
prevent inefficient operation of other plants
Most valuable close to load

Conclusion
Diesel fuel displacement is the near termmarket with real economics
Isolated utilities are the real trailblazers
Require a lower cost development process Simpler models
The larger utility market requires regulatory
change Transition in stages
We live in interesting times
