1 SCALE IT UP: HOW NYC AGENCIES WILL REACH 80X50 Panelists: Tarek Arafat, NYC Department of Citywide Administrative Services (DCAS) Chris Diamond, NYC Department of Design & Construction (DDC) Mikael Amar, NYC Department of Environmental Protection (DEP) Bomee Jung, NYC Housing Authority (NYCHA) Jessica Wurwarg, Caitlin Churchill, NYC Department of Transportation (DOT) Moderator: Ellen Honigstock, Urban Green Council

2 About NYC DEP Largest combined water and wastewater utility in the United States: 9 million New Yorkers served by 6000 employees 1.1 billion gallons per day (gpd) of water delivered 7000 miles of water mains, 2000 square-mile watershed 1.3 billion gpd of wastewater and stormwater treated 7500 miles of sewers, 14 WWT plants (WWTPs) Air, noise, and hazardous waste policy & enforcement

3 Trillion British Thermal Units Thousand Metric Tons of CO2e GHG Profile and Energy Use at DEP 800 Greenhouse Gas Emissions by Fiscal Year 700 2nd largest municipal emitter of GHG, 3rd largest municipal energy consumer Over 700 utility accounts at over 300 locations Annual spend on building & transportation energy ~$ million Annual WWT energy usage = 4.3 trillion Btu 695 million kwh electricity 6.5 million therms natural gas 2.5 million gallons fuel oil 192,500 mlbs steam 1.2 billion cu-ft anaerobic digester gas (ADG) 3.6 BCF annual production = ~35% ben. use GHG emissions or energy usage, removing mandated* increases *Several water supply facilities, biological nutrient removal, and combined sewer overflow facilities Site Energy Usage by Fiscal Year

4 Wastewater Treatment Process

5 Wastewater Treatment Plants as Resource Recovery Factories Heat Reuse & Loss Clean Water Residential/Commercial Wastewater Fit-for-Purpose Water Industrial Wastewater Biosolids Products Stormwater Renewable Energy Food Waste Inputs Raw Materials Process Water Reuse Digester Gas Reuse Processing Manufacturing Next Generation Products Outputs Products

6 Citywide Drivers for Change 80% reduction in GHG emissions by 2050 Carbon neutrality in new 1.5 degree Celsius Plan Energy-neutral wastewater treatment plants by 2050 Maximize digester gas production Maximize digester gas beneficial use Minimize digester gas fugitive emissions 100 MW of solar on City-owned properties by 2025 Zero waste to landfills by 2030 Maximize biosolids beneficial use Maximize food waste beneficial use 50 MW enrolled in Demand Response Program by 2017

Has accounted for as much as ~10% of citywide reductions during events. 8,150 8,100 8,050 8,000 7,950 7,900 7,850 New York City (NYISO Zone J) Electric Demand on 8/27/ MW reduction citywide Actual Citywide Load Business-as- Usual Load 6,650 6,600 6,550 6,500 6,450 6,400 6,350 New York City (NYISO Zone J) Electric Demand on 3/2/ MW reduction citywide DEP peak reduction of 22 MW 7,800 7,750 7,700 DEP peak reduction of 24 MW DEP Contribution 6,300 6,250 6,200 Data source: NYISO & DEP RTMs

8 Strategies for GHG Reduction at DEP Demand Side Energy conservation and efficiency Equipment and operational improvements Water demand management GHG Reduction Strategies Supply Side On-site energy generation using anaerobic digester gas Other beneficial uses of ADG Renewables Non-ADG renewable energy Hydro, solar PV, etc. Offsets Beneficial use of biosolids & biogas offsite Sequestration by green infrastructure, wetlands, and watershed

9 Ongoing Demand-Side Initiatives at DEP Energy Conservation Measures: Energy audits completed at WWTPs. Developing plan to integrate ECMs into State-of-Good-Repair capital projects. Analytics, Education, and Accountability: Ensuring data is clean and reliable. Creating performance metrics. Tracking progress of project implementation. Energy in employee reviews. Energy reports and meetings increase transparency. Training and classes. Design Guidelines: Update and implement for more energy-efficient alternatives. Energy Profile Report for each new or reconstruction project. Others: Incentivizing fixture replacements and water reduction challenges. Green infrastructure (Water-Energy Nexus tool).
