The team at StuyTown Property Services has embarked on another sustainability initiative. After extensive research, and engineering, we have identified Combined Heat and Power (CHP), also known as cogeneration as our next green initiative. The Combined Heat and Power Plant produces electricity and thermal energy on site, supplementing energy provided to us from Consolidated Edison.
The CHP plant designed for Stuyvesant Town will generate just over two megawatts of electric power. Simultaneously, the heat generated by the engines will produce steam which will be used to heat and supply hot water for 24 addresses in the south-east corner of Stuyvesant Town. The installation of boilers will help supplement heavy load days and give the property redundancy.
Generally large-scale utilities produce energy at an efficiency rate of 45%- 55%, while using CHP to produce electricity and thermal energy at a local level will operate at a rate of 65%-85% efficiency. The CHP designed for Stuyvesant Town will operate at an 82% efficiency rate which will reduce current greenhouse gas emission by 903 metric tons.
Additionally, the 80 acre property is in the process of installing the largest privately funded multi-family solar array in the country on its 22 acres of rooftops. This project almost doubles the solar capacity in Manhattan and is the equivalent of removing 11,972 cars from the road. The reduction of greenhouse gases, in conjunction with Peter Cooper Village Stuyvesant Town participation in the NYC Carbon Challenge, further emphasizes our commitment to sustainability and leadership in the Multifamily Community in NYC.
1. What is Combined Heat & Power (CHP)?
Combined Heat & Power is the process where natural gas powers an engine connected to a generator. This generator produces electricity and the byproduct of this process is thermal energy (heat). This thermal energy is used to make steam or hot water. This is a very efficient use of energy as there is very little ‘wasted’ energy.
2. Is CHP the same as Co-Generation?
Yes. Co-Generation, or COGEN, is another frequently used term.
3. How exactly does Combined Heat & Power Plant (CHP) work?
A good explanation of CHP can be found here.
4. Why are you doing this?
The CHP system installation is the next phase of StuyTown Property Services’ sustainability initiative to reduce PCVST’s Greenhouse Gas Emissions (GHG). The project will reduce current GHG by an estimated 903 metric tons annually; the equivalent of 2.2 million miles driven by an average passenger vehicle.
5. How large is the project?
The project will generate two megawatts of electric power and enough thermal energy to provide hot water / steam to 24 StuyTown addresses.
6. Have other residential buildings installed CHP?
Yes, other buildings in NYC have installed CHP systems. Hudson Yards will have a NYC leading 13.2MW CHP system providing electricity and steam/heat for both residential and commercial space.
7. Will the Combined Heat & Power Plant (CHP) Unit be visible?
No, the CHP unit itself will be housed in a green roof structure between the 245 Ave C and 271 Ave C buildings. The final structure, at 14’ above grade, will convert the current landscaping department’s chain link fenced warehouse area into a beautiful green roof garden along with a garden on the M level.
8. Will there be a Major Capital Improvement (MCI) charge added to the rents because of this project?
No. This project will not be filed as a major capital improvement. There will be no cost to residents.
9. Will this initiative affect my heat or power?
No, there will be no difference to the power, heat or hot water in your apartment.
10. Does the Combined Heat and Power Site pose any health risks?
There are no health risks that come with the installation or operation of this system.
11. What will Combined Heat & Power Plant (CHP) be powering?
The CHP plant will provide heat and hot water to 24 addresses in the south-east corner of Stuyvesant Town. The estimated 2 megawatts of generated electric power will go directly into the conEdison grid.
12. Will the Combined Heat & Power Plant (CHP) be noisy?
No, baseline noise level readings have been taken to assure that the CHP plant will create no more noise than what exists today. With regards to construction, communication regarding that timeline will be provided to residents and in accordance with StuyTown Property Services construction days/hours. Calendars (two weeks at a time) will be posted in bulletin boards informing residents of red (loud), yellow (intermittent noise), and green (minimal noise) days.
13. Who is responsible for maintaining the Combined Heat & Power Plant (CHP)? SPS or ConEd?
SPS is responsible for all maintenance relating to equipment and the structure.
14. Is the Combined Heat & Power Plant (CHP) a permanent addition to the property?
Yes, the structure is permanent and the life span of the equipment is 20 years.
15. What is the timeframe for this project?
The construction of the CHP structure is planned to begin this fall and continue through mid-2020. Again, specifics will be made known to residents, especially those in surrounding buildings, when known throughout the project.
16. Is ownership looking at other renewable sources?
StuyTown Property Services continues to look at new technologies and other ways to reduce GHG emissions from the two communities.
17. Will there be any work that requires access to my apartment?
No, there will be no need to access resident apartments.
18. Where and when will this work occur?
The work will be completed from 9am – 5pm on the site between 245 Avenue C and 271 Avenue C, just above the Garage #5 entrance. Work will also occur in various mechanical rooms located on Avenue C as the heat/steam is tied into current systems. At times, staging will occur on the Avenue C Loop Road, the service road on Avenue C, and other areas as needed.
