11. Initial ideas discussed…
Future Voluntary Renewable Programs Stakeholder Group
Initial ideas discussed…
Idea
Description
C&I direct contracting
Offer ability for commercial and industrial customers to sign a wind or solar contract either directly with an independent power producer or through some type of utility pass-through apparatus (e.g., sleeve contract)
Coal and gas plant early retirement
Use voluntary customer programs to finance early retirement of fossil-fuel plants and investment in replacement plants with no/low-carbon emissions
Community renewables
Offer renewable energy programs geared toward communities that are seeking to meet aggressive carbon reduction goals. Review several models including an umbrella offer or an opt-in. An umbrella offer is… and an opt-in model is…
Environmental dispatch
Use voluntary customer programs to enable the dispatch of power plants based on emissions characteristics rather than just their costs
Excess Renewable Energy Credit (REC) donation
Contribute RECs that the company has acquired, but will not be used for compliance, into a program that allows low-income customers to receive environmental benefit

12. Future Voluntary Renewable Programs Stakeholder Group
Idea
Description
Join Southwest Power Pool
Join an RTO/ISO, such as the Southwest Power Pool, to make it cheaper to integrate more renewables and to enable customer participation, using their distributed energy resources, in wholesale markets
Leverage Renewable Energy Trust to fund renewables programs
Use funds remaining in the Renewable Energy Trust to fund renewables investment for low-income customers
Long-term fixed price
???
Matching renewables subscriptions
Allow customers to make voluntary contributions that sponsor enrolment of friends or family in Windsource, Renewable*Connect, Solar Rewards Community, or Solar Rewards
Use social cost of carbon (SCC) in decision-making
Include SCC in resource planning
Wind curtailment
Reduce the curtailment of wind by storing kWh where curtailment was previously necessary and discharging stored energy during hours when it would displace coal or natural gas generation

Meeting held on September 8.
Main Request – PLEXOS Modeling Inputs
Follow-up with Rick Gilliam (Vote Solar) on Wednesday, September 13.
Response: The Company is unwilling to provide the highly confidential inputs for Vote Solar’s contemplated PLEXOS model runs. The Company is willing to work with Vote Solar and other interested parties to complete modeling on their behalf. The Company will start by establishing some base model runs and then sharing those with Vote Solar. Further technical meetings may be necessary to discuss runs and other necessary adjustments to modeling.
