Colorado “Our Energy Future” Plan — In January 2016, PSCo introduced the “Our Energy Future” Plan in Colorado. This proposal
ties together innovative technology, economic development and customer initiatives to give customers more control over their energy
use, prepare for the future energy demands of the state and keep rates competitive. The key components of the plan, which includes
several filings with the CPUC, are as follows:
• Two Innovative Clean Technology pilot programs in partnership with leading companies to address electric battery efficiency
and reliability including demonstrations to test microgrids and battery technologies for integration of distributed resources;
• Alignment of PSCo’s pricing in a more fair and equitable manner for Colorado customers;
• Introduction of Solar*Connect®, a new, cost-based program that will offer customers a choice to sign up for 100 percent
solar power and add an incremental 50 MW of solar generation;
• Investing in natural gas reserves to take advantage of historically low natural gas prices by locking in current costs to provide
long-term stable rates for customers;
• Exploring opportunities for up to 1,000 MW of additional renewable resources to be presented later this year for
consideration by the CPUC; and
• Presenting an intelligent grid proposal later this year focusing on interactive meter technology that will improve customer
choice and control of their energy use.
RES Compliance Plan — Colorado law mandates that at least 20 percent of PSCo’s energy sales are supplied by renewable energy
through 2019, with the percentage increasing to 30 percent by 2020 and includes a distributed generation standard. PSCo is in
compliance with the RES as of Dec. 31, 2015.

(a) This category includes wind energy de-bundled from RECs and also includes Windsource RECs. PSCo uses RECs to meet or exceed state resource requirements
and may sell surplus RECs.
(b) Distributed generation from the Solar*Rewards program is not included, and was approximately 245, 197, and 172 million net KWh for 2015, 2014, and 2013,
respectively.
