Phase 2
Clean●Green● Sustainable●Steam

3. Project Background
The existing D-Area Powerhouse was built in 1953 and provides steam to nuclear and industrial activities in F-, H-, and S-Areas. It is a co-generation facility and provides approximately one half (20 MW) of the Site’s electrical demand.

4. Project Benefits
Greenhouse Gas (GHG) emissions reduced by 100,000 tons a year significantly decreasing the carbon footprint of the SR Site
Overall annual air emissions rates will decrease
Particulate Matter > 400 tons a year,
NOx > 2,500 tons a year
SOx > 3,500 tons a year
The amount of river water currently drawn from the Savannah River will decrease by over 2.8B gal per year
Sustainable design methods are being used and energy efficient technologies incorporated

5. September 14, 2009 to January 2012

6. Integrated Project Team
IPT formed in September 2009
Included CO, FPM, representatives of FRs, Permits, SRNS, technical representatives as required
Held meetings every week for the two-year construction period
Provided input to the IMRT which has met every quarter

7. Truck Off Loading Pad First footer poured in June 2010
Three off-loading pads
Dump time is 6-10 minutes
The hopper holds two loads (80T wood chips)
50 trucks per day is about 1 truck load every 15 minutes

8. Stacker Reclaimer First footer poured in May 2010
Receives chips from the transfer tower
Holds about 800 truck of wood chips (32K Tons)
About a 30 day supply at 1KT per day

9. Steam Line Interconnection
Major Effort & Coordination with Ameresco, DOE, & SRNS
Coordinate interconnection during planned site steam outage
Successfully completed April 12, 2011

10. 13.8 kV Line Tie In Decision made to use the MOX substation vs F area
Worked with SCEG, MOX, DOE SR
18 months of effort
SCEG approved design in May
Construction started in June
Burma Road powered off of MOX substation August 10, 2011
Ameresco to provide 30% of the SRS power and 100% steam from renewable fuel

11. Burma Road Construction (from 3K Feet)

12. Burma Road Construction Safety

13. Steps of Commissioning & Startup
Ameresco System Commissioning of 30 systems
Ameresco Equipment Performance Testing
DOE–SR Team Readiness Assessment

14. Project Successes Construction Status
Over 600,000 safe manhours
38 acres of site clearing, 150K CY of fill, 13,000 cubic yards of concrete, 812 tons of steel, 42,000 linear feet of pipe
750,000 ft (142 miles) of cable  
200 motors installed 
45 pieces of major equipment procured & installed
1,900 instrumentation I/O loops
150 workers (daily average on site during construction) 
Started Operations 2 months ahead of original baseline schedule
Ameresco to provide 30% of the SRS power and 100% steam from renewable fuel by February 2012
Great Team Effort – Ameresco ● DOE ● SRNS

15. Summary of First 3 Years of Operation
The heating plants were commissioned in October 2010 and went into operation in November 2010
The main facility was commissioned in 2011 and went into commercial operation in January 2012
After the first year of operation
main facility has provided 1.7 billion pounds of steam
600 million pounds of steam exported to SRS
97,000 megawatts of green energy generated to the site electrical grid
After the first three years of operation
the main facility has provided 5.2 billion pounds of steam
1.3 billion pounds of steam exported to SRS
299,400 megawatts of green energy generated to the site electrical grid ($23.9M)
This program is a great example of private industry and the federal government forming a partnership and working together for success

16. Phase 2
Getting started 16

17. Phase 2
Starting site prep – package boiler moved by Dec and biomass by June 2016 17

18. Advantages of the Phase 2 Project Independent source of steam
Advantages of Phase 2
Advantages of the Phase 2 Project
Independent source of steam
Optimize Power
“Hospital start” capability of package boiler
Independent source of electrical for phase 2
Package and biomass boilers enclosed inside building
Capability to run condensate through the package boiler to help keep in warm stand by 18
