Issues/Opportunities

5

• Things are starting to get blurred– Traditional small retail type loads are

becoming generators; do our current pricing models work for this new paradigm?

– Beginning to shake up the traditional model; can load and generation continue to be looked at independently anymore?

• Optimization required– Pricing signals need to be aligned– Minimize un-intended outcomes– Need to assess value received from the

system, adjust pricing models– Need to explore this collaboratively with

stakeholders
