Yesterday afternoon, the Minnesota Public Utilities Commission approved the methodology for calculating value of solar (VOS) tariffs in Minnesota as developed by the Department of Commerce. In doing so, Minnesota became the first in the nation to adopt a VOS tariff methodology.

The Commission was required by statute to take action on the VOS calculation methodology by the end of the month. It had three options: to approve it as proposed, reject it, or approve it with modifications and with the consent of the Department. For background on the Department’s January 31st recommendation, see our blog posts here and here. The Department subsequently included several modifications affecting the fuel price escalation factor, the avoided distribution capacity cost, and the environmental cost categories.

In its ruling, the Commission approved the Department’s methodology, as amended, by a 3-2 vote.Continue Reading Value of Solar Achieves a New Dawn in Minnesota

Final comments were filed yesterday on the proposed methodology for calculating a value of solar (VOS) rate for utilities in Minnesota (more on the proposed methodology is here). With the Commission required to make a decision within 60 days of January 31, 2014, parties remain in fairly wide disagreement about what is required by statute, particularly what values are truly “known and measurable” and whether the value calculation or proposition applies to the particular utility or more broadly to society. Depending on the interpretation of these factors among others, the estimated  VOS rate could vary from half of that suggested by the Department’s original $0.135/kWh example to something considerably higher. The rate would eventually apply to Xcel’s Community Solar Garden (CSG) Program and potentially as an alternative to net-metering arrangements for projects under 1MW. In a separate proceeding yesterday, the Commission set interim rates for the CSG program that could be even higher with a placeholder SREC value included (more on that in a separate blog).

California Governor Jerry Brown recently signed a new law that could significantly expand virtual net energy metering in California. Since 1996, California utility customers owning renewable energy systems have been able to offset their electricity bills with credits earned by feeding power generated by their systems back to the utility. SB 594 amends California’s net metering law to allow customers to aggregate energy consumed at multiple meters located on their property (or on their contiguous property) and net that use against the power produced by the customer’s renewable facility on the same site.

Meters on contiguous properties must be solely owned, leased, or rented by the eligible customer-generator to be included. Parcels divided by a street, highway, or public thoroughfare are considered contiguous provided that they are otherwise contiguous and under the same ownership. The customer-generator will be able to use the sum of the load of the aggregated meters for purposes of establishing the maximum size renewable generation system to be used for net metering purposes. However, the existing maximum size limit (1 MW) for net-metered generation facilities will apply to customer-generators aggregating multiple meters. Overall, expanded virtual net metering would provide a way for many customers with multiple meters to use on-site generation more efficiently and economically.

Implementation of SB 594 is contingent upon the California Public Utilities Commission (CPUC) making a determination that the expanded virtual net metering program established by the bill will not result in costs being shifted to non-participating ratepayers. The CPUC is required to make this determination by September 30, 2013.Continue Reading SB 594 Signed into Law: Intended to Expand Virtual Net Metering in California

Renewable energy supporters in Utah are cheering a recent order which will make renewable energy systems such as wind turbines and solar panels more cost effective for consumers.

On February 12, 2009, the Utah Public Service Commission issued an order revising the Rocky Mountain Power net metering policy. In the past customers who own renewable-energy…
