  2. GREENPOINT MANUFACTURING AND DESIGN CENTER The Greenpoint Manufacturing and Design Center is a 15-year-old nonprofit organization dedicated to the preservation and creation of blue collar jobs for low-income New Yorkers. To date, it has renovated more than 700,000 square feet of space for small manufacturers, artisans and artists. GMDC is currently near completion on an $18 Million project at 221 McKibbin Street, a 72,000 SF industrial rehab that utilizes New Markets and Historic Tax Credits. 221 McKibbin Street

  3. GENESIS OF THE IDEA • Nonprofits function as entrepreneurial risk-takers that can create replicable models for public and private sectors to emulate. • Ample rooftop space on manufacturing buildings throughout the 5 boroughs. • Potential insurance policy for GMDC tenants against electrical rate fluctuations. • In 1999, GMDC thought 810 Humboldt Street would be a food production facility with heavy electrical loads.

  4. 810 HUMBOLDT STREET • 80,000 SF Industrial Bldg • 13 units ranging in size from 1,000 SF to 20,000 SF • Predominantly woodworkers • Irregular electrical load: little use on Sundays • 2 separate electrical services

  5. SELECTING AND SCALING THE SYSTEM Proposed 150 kW Array circa 2001

  6. SELECTING AND RESCALING THE SYSTEM Final 59 kW Array circa 2002

  7. DIVIDING THE SYSTEM IN TWO  810 HUMBOLDT STREET 150 kW  115 kW  59 kW 1155 MANHATTAN AVE 56 kW

  8. INSTALLATION AT HUMBOLDT • New electrical panel and redistribution of tenant service • Reverse power relay • required by Con Edison • Experimental zinc bromine battery storage modules installed • Required approval from the NYC Bureau of Electrical Control • Panels in place: 2002 • System activation: 2004 • Battery removal: 2006 • PV Surface Area: 5,900 SF NEW ELECTRICAL PANEL REVERSE RELAY INVERTER/TRANSFORMER/SWITCHES

  9. HUMBOLDT STREET PV PERFORMANCE ANNUAL OUTPUT WEEKLY OUTPUT

  10. 1155 MANHATTAN AVENUE • 300,000 SF Industrial Bldg • 70 units ranging in size from 1000 SF to 20,000 SF • Light industrial and artisanal tenants • Very heavy and continuous electrical load • 56 kW PV installation: roughly 8% of building load • No reverse relay • System installed: 2005-2006 • PV Surface Area: 5,600 SF

  13. ISSUES WITH REPLICABILITY OF MODEL • GMDC paved the way for larger commercial PV systems in NYC on a technical and logistical level, but less so on a financial level. • GMDC had trouble taking advantage of tax credits as a nonprofit, as syndication/investment structures require restructuring of property ownership. • GMDC’s nonprofit experience made us more comfortable with identifying and accessing available subsidies and low-cost debt than the average property owner would be. • GMDC’s model is more relevant to industrial landlords with multiple tenants than to large single-use owner-operators.

  14. LESSONS LEARNED • Need to look carefully at load issues: hard to scale system without a lot of data. • After you scale the system to the load, reduce it further. No net metering means wasted power if the system is too big. • Avoid reverse power relays if you can. • Avoid experimental technologies. • Work out a clear strategy for data collection and billing in advance. • Assume many delays. • Assume unforeseen expenses: utility charges, electrical work, etc. • Weigh PV product options based on your building and roof conditions. • Check your system often to make sure it’s working.
