Performed by Yampa Valley Data Partners (YVDP) For Yampa Valley Electric Association (YVEA) May, 2015 Preliminary Findings, Subject to Revision and Final Approval YVEA compliance pathway for SB-252 distributed generation requirement

Project Background CO SB252 requires co-operatives to meet 1% of their electricity sales by 2020 through distributed generation (DG) technologies. Qualifying technologies include: (1) solar; (2) wind; (3) hydro; and (4) biomass/biogas. DG obligation is split 50/50 between retail and wholesale, such that retail target is ½% (less industrial sales) and wholesale target is ½%. Yampa Valley Electric Association (YVEA) has embarked upon an effort to understand the impact of this requirement on energy purchases and investments. YVEA has engaged Yampa Valley Data Partners (YVDP) to determine current and future DG compliance for retail and wholesale. The preliminary results of this analysis are presented herein.

On the Horizon  More Distributed Generation  Cost of Service study: structure adjustment for grid access  Large scale solar  Storage technologies-peak power off-sets  Incentives for Solar from Coop?? Do our members want to pay for it?
