The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

S.B. 1189

In June of 2014 S.B. 1189 mandated the creation of a voluntary Distributed Energy Resource Program and created new net metering rules. The legislation allows participating utilities to recover costs connected to meeting a 2021 target of 2% aggreate generation capacity from renewable energy sources. Facilities sized between 1 MW and 10 MW will make up 1% of aggregate generation (50% of the total target) while facilities sized under 1 MW will make up another 1% (another 50% of the total target). Twenty five percent of facilities under 1 MW must also be under 20 kW (12.5% of the total target). Renewable energy resources include solar PV, solar thermal, wind, hydroelectric, geothermal resources, wave and tidal resources, recycling resources, hydrogen fuel derived from reneable resources, combined heat and power derived from renewable resources, and biomass resources.

Once a participating utility satisfies the minimum 2% requirement, the utility may invest in renewable energy facilities between 1 MW and 10 MW with a cumulative installed capacity equal to one percent of the utility's previous 5 year retail peak demand average.

S.B. 1189 mandates that the Public Service Commission (PSC) creates a program to offer nonprofits easier access to renewable energy and to incentivize residential customers to become customer-generators by purchasing or leasing renewable generation equipment. The PSC is empowered to determine the appropriate cost recovery for the utility by determining avoided and incremental costs, but must limit annual cost recovery costs to $12 for residential customers, $120 for commercial customers, and $1,200 for industrial customers.

The PSC will submit report to the General Assembly about the Distributed Energy Resource Program and net metering to the general assembly no later than July 31st 2016. The program will expire on January 1, 2021, but cost recovery will continue until all costs are recovered.

Emerging program details will be recorded in PSC Docket 2014-246 E.
