NY State Requirements for Commercial and Utility-Scale Solar Projects

Large-scale solar projects are subject to specific environmental regulations and grid interconnection requirements, due to their impact.

  • Although solar panels produce no emissions while operating, a large array can cover extensions of land that could be used for agriculture or other purposes.
  • Large solar arrays also result in significant power generation peaks around noon, and their impact on the local grid must be analyzed before approval - this is especially important for megawatt-scale projects.

NY Engineers can help solar developers meet all local requirements with ease, but getting familiarized with them is helpful nevertheless. The following are the main requirements to keep in mind before starting a commercial or utility-scale solar PV project in New York state:

  • New York City DOB Construction Codes
  • New York State Uniform Codes (project located in other NY state jurisdictions)
  • New York State Environmental Quality Review (SEQR), for solar projects covering more than 10 acres, or more than 2.5 acres in agricultural districts The SEQR is not required for rooftop solar projects.
  • Standard Interconnection Requirements
  • Utility-specific requirements: Central Hudson Gas & Electric, Consolidated Edison, National Grid, New York State Electric & Gas (NYSEG), Orange & Rockland Utilities, PSEG Long Island, Rochester Gas & Electric
  • Coordinated Electric System Interconnection Review (CESIR), generally required for projects larger than 50 kW.

These are general requirements for large solar projects in New York, but additional requirements may apply depending on the specific jurisdiction and site conditions. NY Engineers can help you meet any combination of code,environmental and utility requirements.

The PV array layout also indicates how modules are grouped into string circuits and connected to their respective inverters.

Solar PV Simulation Results

NY Engineers will simulate the annual and monthly electricity output of your solar panel system. This data can then be used to calculate the annual savings achieved by self-generation sol projects, and the annual revenue provided by grid-scale projects.

We can also simulate the performance of energy storage systems (ESS), to determine their optimal capacity and assess their financial viability.

Single-Line Diagrams and Equipment Schedules

Our single-line diagrams are intuitive and highly detailed, making them a very useful tool for both solar installers and maintenance personnel. All solar components are labeled and clearly described in construction drawings, and their locations can be easily identified.

NY Engineers will provide specification sheets and manufacturer data for solar panels, inverters, racking systems, and all other equipment specified in your project.

Structural and Racking Details

Our solar design engineers can work with all the types of penetrating mounts and ballasted mounts used in rooftop solar arrays, and they can specify the best option for your project. They also have ample experience with the structural and racking system designs used for ground mount, canopy and carport installations.

All our designs are stamped by a NY State Professional Engineer (PE) or Registered Architect (RA), as required by local authorities.

Permitting and Interconnection Documents

When local permits and utility interconnection requirements are not managed properly, they can greatly delay a solar power project. NY Engineers can help you avoid these hurdles, making sure that all documents related to permits and utility interconnections are filed properly from the start.

There is no need to worry about the Special Use Permit, State Environmental Quality Review (SEQR), Coordinated Electric System Interconnection Review (CESIR) and similar requirements from local authorities and electric utilities. At NY Engineers, we have ample experience with this documentation.

Solar Incentive Applications

NY Engineers will design your solar PV system according to the requirements of local incentive programs. We focus on a quick approval, to secure rebates before funding runs out or the incentive rate is decreased.

Our solar design team can get your project approved under NY state incentive programs, such as those offered by NYSERDA:

  • NY-Sun Megawatt Block Program
  • NY-Sun Incentive Adders, when allowed by project conditions
  • Retail Energy Storage Incentive Program
  • Low-interest financing from the NY Green Bank

NY Financial Incentives for Commercial and Utility-Scale Solar Projects

 

The New York State Energy Research & Development Authority (NYSERDA) manages the largest solar incentive programs locally, and they include both rebates and low-interest financing.

The NY-Sun Megawatt Block Program is the largest solar incentive program in New York state, where incentives are calculated based on location and scale. The incentive program is divided into three regions:

  • Con Edison
  • Long Island
  • Upstate New York

In each region, the incentive rate for solar projects is determined based on scale, and there are three categories: residential, nonresidential and commercial/industrial. NYSERDA provides real-time information about the availability of funds and incentive rate for each combination of project scale and region.

Solar projects may qualify for higher incentive rates (adders) if they fall under certain categories: Community Solar Adder, Brownfield and Landfill Adder, Multifamily Affordable Housing Adder, and Parking Canopy & Rooftop Canopy Adder.

NYSERDA also offers the Retail Energy Storage Incentive Program for solar+storage projects up to 5 MW of capacity. The incentive is also available for stand-alone energy storage.

The NY Green Bank is a NYSERDA division that finances privately-owned large-scale solar projects in the state. The NY Green Bank provided $438 million in financing during fiscal year 2021-2022, reaching a cumulative investment of over $1.7 billion.
