After a full day of hearing arguments on Xcel’s proposed Community Solar Garden (CSG) program (see more on that here), the Minnesota Public Utilities Commission deliberated in public on the issue yesterday and made some important modifications to Xcel’s proposal. The program would allow Xcel customers to invest in off-site solar facilities and receive bill credit for their portion of generation. Ultimately that credit would be at the Value of Solar rate, but as parties await a decision on the Value of Solar (VOS) methodology (more on the VOS here), the Commission settled on an interim rate for the program (though its final vote on the matter is still forthcoming). It is largely based on average retail rates but importantly includes a placeholder value of any transferred Solar Renewable Energy Certificates (SRECs). A CSG developer could transfer the S-RECs to Xcel at a compensation rate of $.02/kWh for facilities with a capacity greater than 250 kW and at $.03/kWh for those with a capacity of 250 kW or less. The S-REC value is not intended to reflect a market rate and is intended and is intended to be strictly temporary, expiring upon the approval of Xcel’s VOS tariff. Furthermore the rate and S-REC value are to be reviewed annually and adjusted if necessary.
The illustrative range of rates (assuming the SREC is transferred) is as follows:
Residential: $.14033 or $.15033
Small General: $.13738 or $.143738
General Service: $.11456 or $.12456
In addition, Xcel’s proposed 2.5 MW quarterly cap on the program was removed given the statute precludes a cap. While a final decision has not yet been issued by the Commission, newsmedia have already begun to report on it (see Star Tribune article here).
