Conclusions

Architecture is key to integrate the different aspects of the smart grid. (If leftalone, man vendor s stems most likel will not be com atible in the future.

Smart grid developments will improve renewable energy resource integration,and can provide a substantial support to the achievement of state targetsdefined in the 2007 Integrated Energy Policy Report.

A collaborative effort among all the stakeholders is needed to develop asmart grid vision for California.

Use cases are needed that could then be used to derive a foundation ofsmart grid infrastructure requirements and technology requirements.

Demonstrations of technologies are also needed to advance the vision.

Customers can better mana e their ener needs and education is needed

to understand application benefits and ways to capture value.

Customer choice is imperative as needs vary across customer classes andcustomers have diverse preferences.
