1. Summary
This decision completes our rulemaking and establishes policies for ownership and operation of distributed generation and their integration into utility planning and operation of the distribution grid. We find that there is no need to place restrictions on ownership of distributed generation units. The technology of electricity distribution, however, necessitates that a distributed generation owner will only be eligible for compensation for deferring distribution system upgrades in limited circumstances, described herein, and only if the distributed generator offers physical assurance. Similarly, since almost every retail sale will utilize both the distribution and transmission networks (even those that appear to stay within a single circuit), we do not adopt a distribution-only tariff.
The nature of this new technology and its likely uses obviates the need to make any changes to rate design to accommodate distributed generation at this time. Nevertheless, we do allow the utilities to establish memorandum accounts to track distributed generation implementation costs that cannot be attributed to specific distributed generation projects and are not part of the utilities' existing budgets.
We do not adopt a mass marketing information campaign about distributed generation, but rather a multi-pronged education effort directed to those considering a distributed generation installation.
To allow us to consider ongoing issues, we state our intent to open a new rulemaking - related to distributed generation.
