6 Energy Supply Large Wind Wind Energy Feasibility (GNWT) Inuvik and outside Yellowknife (Snare System) Inuvik: Storm Hills & Inuvik High Point Monitoring at Snare and Inuvik Potentially 7-10MW Expression of Interest ntpc.com 6

7 Solar Photovoltaic (PV) Power How are we doing? Existing Solar PV Installations Sachs Harbour- 4.3kW Inuvik- 5kW; 7kW; 2kW; 3.5kW; 10 kw;10kw Paulatuk- 5kW; 1.7kW Fort Good Hope- 5kW Norman Wells- 2.9kW Fort Simpson kW; 5kW; 5kW Nahanni Butte- 4.8kW Jean Marie River- 1.3kW Gameti- 5kW Wekweeti- 4.2kW Whati- 5kW Behchoko- 4.8kW; 5kW Yellowknife- 2kW; 5kW; 5kW; 1.8kW; 1.3kW; 33.5kW Hay River- 1kW; 1.7kW Fort Smith- 0.5kW kwh/kw Total: kw (2103) Total: NOW > 545kW

8 Renewable Energy Initiatives Net Billing 2010 / Net Metering 2013 Success: NTPC 55kW of installed solar capacity (NUL 40kW) Customer: Positive return banking credit at 1:1 Utility: Capacity building Challenge /Perseverance: Slow uptake / Administration IPP Lutsel K e Dene First Nation Success: PPA flexible option to meet community needs; Solar Energy Strategy Challenge /Perseverance: Policy ntpc.com 8

9 104kW Solar PV Fort Simpson Success: (2012) First Utility-Scale Low Penetration (solar system production 12% average community load) Saves 27,900 L diesel fuel or 76 tonnes GHG / Yr. Made possible through GNWT funding No vandalism Challenge: Solar production is less that 2% annual consumption 2.2 million L / Yr. in diesel fuel required to meet load ntpc.com 9

10 Colville Lake Community Located: Sahtu Region 745 km by air NW of Yellowknife Population: 147 Average Load: 50 kw Peak Load: 150 kw Challenge: Remote, economies of scale, during summer months air access only; one of the highest cost communities to serve ntpc.com 10

11 Challenge Why New Power Plant? Oldest NTPC plant 24 years Settling issues Reliable, stable power challenging to provide Load size Changing load characteristics No longer meeting (Required Firm Capacity) RFC criteria ntpc.com 11

12 Success: Meeting some needs of the community: Relocate diesel plant Reduced noise /odour in community/ reduce GHG s Employment during construction and decommissioning of old plant and relocation of fuel tanks ntpc.com 12

13 136.5kW Solar PV Colville Lake Solar / Diesel Production Modelling dec nov oct Solar sep aug jul Diesel jun may apr mar feb jan 0% 20% 40% 60% 80% 100% ntpc.com 13

14 Demonstration Project Challenge: Permit Application? What is a demonstration project? Perseverance: Projected 1% rate increase to thermal region. (. 6% power plant;. 4% Solar and BESS) ntpc.com 14

15 136.5kW Solar PV Colville Lake Phase I Solar 54kW (October 2014) Phase II Solar 82.5kW (June 2015) 112MWh expected solar generation Success: No shipment damage to solar panels On schedule on budget Capacity building / relationship building Cost/ kw installed solar reduced $12.20/W from Fort Simpson (Phase I) to Colville Lake (Phase II) $6.34/W 31,600 L diesel fuel or 86 tonnes GHG / year Average diesel consumption is 160,000L ntpc.com 15

16 Challenges Edmonton plant build duration: Deteriorating winter road conditions Switch gear build wrong parts Engine testing before dispatch ntpc.com 0

17 Challenges Short construction season: Early June before work starts on solar phase II Predetermined location rather than choose a site Load bearing survey of whole runway - exact location unspecified ntpc.com 1

18 Challenges Schedule on site: Shipping damage assessed Further engine testing On site availability of SAFT & ABB field engineers ntpc.com 2

19 Challenges Meeting the budget: Demonstration/pilot project Extras not initially envisioned NTPC Labour costs 570 Transporation & accommodation 244 Consultants 224 Contractors 2,648 Diesel engines 196 Accessory electrical equipment 436 Battery bank 984 Solar panels 934 Federal funding -150 Territoral funding -1,145 Overhead (22%) 1,311 Sub-total 6,252 IDC (5.68%) 353 Total 6,605 ntpc.com 3

20 PERSERVERANCE: Sourcing a Battery Supplier: First winning proponent declared bankruptcy RFP process repeated Engine testing: Usual bugs in systems before real progress Shipping date brought forward Reduced time to dismantle and pack plant Damage After Shipping: Reduced speed during shipping Damage to switch gear and some engine systems ntpc.com 4

21 SUCCESSES: Contractors: Plant build - Adco Power Ltd northern experience Solar - Azgard Corporation and Green Sun Rising Battery Module &Controls - SAFT Batteries & ABB Inc B.A.F.N. construction support Testing and commissioning: Successful testing of batteries and diesel Successful testing of PV curtailment Powering community soon: ntpc.com 5
