Biomass Cogeneration Facility Savannah River Site Aiken SC
Biomass Cogeneration Facility Savannah River Site Aiken, SC November 2015 SC Biomass Council Quarterly Meeting
Savannah River Site Project Overview Clean●Green● Sustainable●Steam • • • Project Background & Drivers Project Scope Project Benefits Program Status Construction & Start of Operation • Summary of Operation • Phase 2
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. 3
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 – NOx – SOx > 400 tons a year, > 2, 500 tons a year > 3, 500 tons a year • The amount of river water currently drawn from the Savannah River will decrease by over 2. 8 B gal per year • Sustainable design methods are being used and energy efficient technologies incorporated 4
September 14, 2009 to January 2012 5
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 6
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 (80 T wood chips) • 50 trucks per day is about 1 truck load every 15 minutes 7
Stacker Reclaimer • First footer poured in May 2010 • Receives chips from the transfer tower • Holds about 800 truck of wood chips (32 K Tons) • About a 30 day supply at 1 KT per day 8
Steam Line Interconnection • Major Effort & Coordination with Ameresco, DOE, & SRNS • Coordinate interconnection during planned site steam outage • Successfully completed April 12, 2011 9
13. 8 k. V 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 10
Burma Road Construction (from 3 K Feet) 11
Burma Road Construction Safety 12
Steps of Commissioning & Startup • • 13 Steps of Commissioning & Startup Ameresco System Commissioning of 30 systems Ameresco Equipment Performance Testing DOE–SR Team Readiness Assessment
Project Successes • Construction Status – Over 600, 000 safe manhours – 38 acres of site clearing, 150 K 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 14
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. 9 M) • This program is a great example of private industry and the federal government forming a partnership and working together for success 15
Phase 2 • Getting started 16
Phase 2 Starting site prep – package boiler moved by Dec and biomass by June 2016 17
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
