Combustion, Cooling & Energy Conservation Workshop A Success Story of Strategic Energy Management: The International Skating Center of Connecticut Linda Yoder Shipman & Goodwin

ISCC's World Class Twin Rink Facility • 2000 seat twin rinks • Olympic rink: 200' by 100' • NHL rink: 200' by 85' VIP lounge overlooking Olympic rink • Dance Studio • Weight training and fitness room • Pro Shop figure skating equipment & apparel • J.A.M Pro Shop hockey equipment • Skater's Café • Studio 202 INC.
Energy Bills Prior to Initiatives • Electricity - $22,000 - $25,000 per month – Average Demand = 370 kw – Demand Ratchet = 450 kw
• Natural Gas - $6,000 - $8,000 per month
Key Cost Drivers • Electricity – Ice refrigeration – Lighting • Natural Gas – Fuel makers for ice resurfacers – Munters units for dehumidification
4 Step Process • 1. Understand bills – cost drivers, demand ratchets • 2. Become efficient (no sense buying or generating kilowatts you don’t really need!) • 3. Install Distributed Generation • 4. Bid remaining commodities into competitive market
Cost Reducing Initiatives • Become Efficient – Lighting upgrade with Alliance Energy – Use CT Energy Efficiency Fund Express Rebate Program • • • • • • •
Total cost of lighting project = $82,680 Rebated amount = $46,800 Net Cost = $35,880 Annual Energy Savings = 290,389 kwh Monthly electricity savings = $2420 Estimated Payback = 1.24 years Interest Free Financing Program for 18 months = immediate $500 per month savings
– Change lighting design within the facility to use only the amount of light necessary, not turning on all lights all the time – Controls and sensors on office and exercise space lighting – HVAC “tune-up” (clean/replace filters, clean ducts, etc.)
Install Distributed Generation • Investigated many different applications – Photovoltaics – Fuel Cell – Combined Heat and Power – Microturbines
• Microturbines selected as starting point due to most efficient use of waste heat
Install Distributed Generation • Install 2 Ingersoll Rand 70 kw Microturbines
Funding For Distributed Generation • Applied for grant under Section 8(a) of the Energy Independence Act ($450/kw for baseload generation) • Grant approved within four weeks for $60,300 • Low-interest financing for balance of project costs $259,000 approved by DPUC
Other Financial Benefits • 1. Tax Credit – 10% capital cost • 2. Natural Gas Transportation Credit • 3. Capacity Payments • 4. Class III REC Revenue
Overall Financial Picture • Total Cost of Project = $334,800 • Total Incentives (less financing) = $97,297 • Avoided Electricity Costs (Year 1) = $143,920 • Avoided Natural Gas Costs = $86,952 • Turbine Fuel Costs = $122,956 • Annual Maintenance Costs = $10,986 • LESS THAN 2 YEAR PAYBACK • Cost of Microturbine Generation ~ $0.0763
Competitive Commodity Supply • After ascertaining natural gas needs, bid into competitive gas market • Reduced rates by almost $2/MMBTU through 3-year competitive contract
Future Plans • Augment remaining electric needs with ~ 100kw photovoltaics on roof • Drill irrigation well to provide water for ice making • Upgrade ice resurfacers to electric, then fuel cell models (currently natural gas)
S&G’s Other Projects • 1. Turbine installation in metal finishing manufacturer with waste heat used to heat ovens; similar economics as ISCC • 2. Fuel cell in new high school construction; better economics • 3. Small biomass in tobacco wrapper manufacturer; still working through economics • 4. Combined heat and power installation in manufacturing facility; similar economics
S&G Process for Clients • 4 steps (understanding, efficiency, DG, commodity) • For DG, issue RFP for alternative energy source (let the experts determine best fit for the facility) • Apply for all available grants, financing, etc.
