Solar Growth Trends
Regulation of Solar Services Agreements (SSAs) has emerged as an important issue in supporting solar growth.
Confusingly, Power Purchase Agreement "PPA" is often used in reference to SSAs, however, PPA has long
been the term for an wholesale sales agreement between a generator and a utility, but a SSA is
actually a retail sales agreement between a solar array owner and the utility customer hosting a
solar array.
This arrangement has become the norm, as SSA providers are able to use the
available federal tax credits and depreciation, and free the host from tying up capital and taking
on the risks of ownership.
By overcoming a number of barriers to customer uptake of solar, SSAs
have become the preferred means for the financing solar by commercial customers and the use
of solar SSAs is beginning to be seen in residential markets.
Because the use of solar SSAs is so beneficial to the growth of solar markets, IREC has been
actively involved in state proceedings addressing participation of solar SSA providers in net
metering and regulation of solar SSA providers as public utilities.
State Policies for SSAs
Over the past year, IREC has
participated in proceedings in Colorado, Nevada, Arizona, New Mexico, Massachusetts and
Michigan that addressed the legal and policy issues surrounding regulation of solar SSAs.
As part of Michigan's adoption of net metering rules, the
Michigan PSC clarified the definition of customer-generator to ensure that SSA providers would
be allowed to participate in net metering.
Likewise, Massachusetts clarified in its net metering
regulations that net metered systems may be owned by third-parties.
IREC continues to be
involved in Arizona and New Mexico's consideration of the matter and anticipates being active in
Washington as well.
