2 Who We Are The Kwadacha Nation (Tsek ene) - Fort Ware 570Km north of Prince George Located at the confluence of the Fox, Kwadacha, and Finlay rivers in the Rocky Mountain Trench.

3 Population of 380 and 80 homes

5 Why Bio-energy? Rely on diesel generators for electricity Propane for heat Expensive, not sustainable, no added benefits for community, concerns with emissions We have LOTS of renewable wood sources

6 The Spanner RE 2 EnergyBlock BC Bioenergy Network funded front end technical & engineering study (2014) Examined different technologies & travelled to Europe to review Spanner RE2 used extensively in Europe with 650+ installations world-wide

7 The Wood Gasification System

8 The Spanner RE 2 Gasifier

9 The Spanner RE2 45KW Generator

10 The Reasonable maintenance & repair requirements Well designed and constructed Safe no-stream operation Can be scaled up (by 45kW units) Provides heat for DES to school and greenhouses Provided as a turn-key plant with chip drier Canadian supplier:

11 The Borealis / Spanner Re 2 Specs Nominal Electrical Power Thermal Energy ( for DES ) Gasifier wood chip consumption Chip Specs Discharge ash (with ash converter) 45 kw 108 kw 45 kg/h (~5.5m 3 /day) ØG30-G40, <13% MC 1-2%, of the input weight 45 kw 108 kw HEAT

12 The Decision (FID) Parallel processes to get to FID: Negotiations with BC Hydro on Energy Pricing Agreement Feasibility Study with Preliminary Design Decision: A 3 Unit CHP Turn-key (135kW el ) with integrated wood chip dryer 20-year EPA for $0.35/kW sold to BC Hydro

13 Biomass Contribution to Total Loads Based on EPA Diesel Generating Station Load Kwadacha s Biomass Generation

14 Moving Forward Project FID (Order Spanner CHP) - February 2016 Grant writing target $1m R. Radloff & Associates - Project Management and lead on Design Build (team of engineering specialists, consultants and contractors) BC Hydro Interconnection significant design work, many documents, BCH charges, negotiations

15 Design Tight timelines meant a design-build process except for DES Long lead time for specialized equipment Spanner plans and documents were in German needed conversion European electrical specs needed to be converted Needed immediate plan for feedstock supply

16 Construction Started August 2016 Target Delivery of CHP mid October 2 ½ months to get site prepared Focus on: Concrete pads for CHP Woodchip storage structure (4 months chip supply) Conversion of old generator building to mechanical room for DES and electrical interconnection

17 Concrete Pad for CHP Chip Storage Under Construction

18 Arrival of EnergyBlock

19

20 Winter construction: slowed pace, added costs and complications

21 District Energy Piping Install

22 Mechanical Room for DES System

23 Continued by community members Initial Training by Borealis and Spanner

24 Inside the EnergyBlock

25 Ready for Commissioning and BC Hydro Tests March 2017

26 Lessons Learned Budget over-runs (+7.3%) with unexpected costs on construction, and CHP equipment, language challenges, freezing temperatures, design-build process and remote location Timeline pressures: Getting to revenue generating ASAP Requirements of granting organizations

27 Lessons Learned BC Hydro BCH supportive but challenging processes, requirements, and documentation Not subject experts (SE) in bioenergy Kwadacha had to retain SE to satisfy BCH questions Insistent on urban power quality standards for this remote area added equipment costs

28 Lessons Learned BC Hydro Negotiating EPA was challenging senior BCH executive helped gain support Significant BC Hydro charges affected feasibility of project BC Hydro assigned a large team assigned helpful and effective BCH team manager We both learned a lot through the process!

29 Lessons Learned The technical specifications for wood chips can t necessarily be relied upon Have supplier test your chips to make sure The Spanner system is good but requires more hands on operations than we thought Dry storage of wood chips adds a considerable cost

30 The supplied modular Sea-Cans for the CHP are tight for space might look at a constructed building for the CHP

31 Gasifier has narrow tolerances for wood chip specs we have to pre-screen chips to reduce fines Lessons Learned

32 Lessons Learned Training and Commissioning phase was not smooth Ensure specific requirements and commitments of suppliers are in agreements before purchase With CHP coming from Germany had to pay significant portion of costs before it was shipped Concerns about on-route damage

33 Benefits Use of renewable locally available resource Creates direct employment Economic benefits for Kwadacha Community pride we are a showcase Direct reduction in GHGs and emissions

34 Benefits Commitment to green energy Provides green-heat to greenhouses and school Project mentor role for other communities Development of partnerships Expandable when needed
