Integrated Resource Plan Integrated Resource Plan Rick Haener September 4th, 2015

Integrated Resource Plan (IRP) • Public utilities first began preparing integrated resource plans (IRPs) in the early 1990s • IRPs are Public Utility Commission (PUC) mandated documents for how a utility expects to provide service to customers for the next 20 years y p p y • IRPs are typically updated and filed with the PUCs every two years • IRPs consider supply ‐ side resources, demand ‐ side measures and transmission options • Balance cost, risk, and environmental concerns • P bli i Public involvement is a key component of the planning process l i k f h l i

Preferred Portfolio Portfolio P6(b) • 301 aMW of energy efficiency over 20 years and 473 MW of reduction on peak by 2034 • Valmy Retirement in 2025 (262 MW) • Actual Valmy retirement date will depend on B2H completion date, the ability to agree on a depreciation date and eventual closure date with NV Energy, and g p gy, PUC approval of an accelerated depreciation schedule • Boardman to Hemingway in 2025 (+500 MW in Summer, +200 MW in Winter) Peak-Hour Date Resource Installed Capacity Capacity 2025 Boardman to Hemingway 500 MW transfer capacity Apr-Sep 500 MW 200 MW transfer capacity Oct-Mar 2025 Retire North Valmy (both units) (262 MW) (262 MW) 2030 Demand response 60 MW 60 MW 2030 Ice-based thermal energy storage 20 MW 20 MW 2031 Combined-cycle combustion turbine 300 MW 300 MW Total retired capacity (262 MW) Total added capacity 880 MW Net peak-hour capacity 618 MW

Action Plan 2015 ‐ 2018 • 2015–2018 B2H and Gateway West: Ongoing permitting, planning studies, and regulatory filings • 2015–2019 Energy efficiency: Continue the pursuit of cost ‐ effective energy efficiency. The forecast reduction for 2015–2019 programs is 84 average megawatts (aMW) for energy demand and 126 MW for peak demand. ( ) f d d d f k d d 2015–2016 Coordinate with government agencies on implementation • planning for CAA Section 111(d). • 2015 Shoshone Falls File to amend FERC license regarding 50 ‐ MW expansion g g p • 2015 Jim Bridger Unit 3 Complete installation of SCR emission ‐ control technology technology

Action Plan 2015 ‐ 2018 continued i d • 2015–2016 Shoshone Falls Study options for a smaller upgrade ranging in size up to approximately 4 MW up to app o ate y 2016 Jim Bridger Unit 4 Complete installation of SCR emission ‐ control • technology gy • 2016 North Valmy units 1 and 2 Continue to work with NV Energy to synchronize depreciation dates and determine if a date can be established to cease coal ‐ fired operations • 2017 Shoshone Falls Commence construction of smaller upgrade • 2017 Jim Bridger units 1 and 2 Evaluate the installation of SCR technology for units 1 and 2 at Jim Bridger in the 2017 IRP • 2019 Shoshone Falls On ‐ line date for smaller upgrade during first quarter

Other Projects Solar PV on Distribution Feeder Lines Install solar PV panels near the end of long distribution feeders to boost/regulate voltage. The pilot project would confirm whether this concept is the lowest cost option in certain cases. Three locations have been identified for the pilot project. Thermal Ice Storage Pilot Project (Ice Bears) Thermal Ice Storage Pilot Project (Ice Bears) Identify and work with a commercial customer to install thermal ice storage. The initial phase would involve identifying a customer, designing the system, and putting together a detailed cost estimate. The second phase would be to purchase and install the equipment followed by data collection for a period of time to determine the th i t f ll d b d t ll ti f i d f ti t d t i th effectiveness of the concept. Shoshone Falls Upgrade Project pg j The previously planned 59 MW expansion of the Shoshone Falls Hydroelectric Project has been scaled back to an upgrade of 1.7 to 4.0 MW. Construction is tentatively planned to commence in 2017.
