The Department of Energy Resources (DOER) has published a new resource for those seeking to learn more about solar PV on landfills. This publication, The Guide to Developing Solar Photovoltaics at Massachusetts Landfills, is a 40-page guide intended to  help local officials identify, evaluate, and pursue opportunities to use undeveloped landfill space to generate electricity. The guidebook speaks to the physical requirements of PV systems, project economics, landfill considerations, procurement details, and the PV development process.

When planning a ground mounted PV system (vs. a roof mount), there are several environmental considerations to evaluate prior to entering a PPA.  The overall size of system, landfill or Brownfield location options, wetland areas, and endangered species are all issues to assess when evaluating sites for PV arrays.  While the solar developer’s engineering team typically has the resources to complete all required environmental permitting, a savvy property owner or municipal committee will want to know “fatal flaws” and/or anticipated permit requirements in advance of committing to the project. Understanding potential environmental challenges ahead of time allows for realistic cost and project timeline planning. The site owner should also confirm that the solar developer has a qualified and experienced permitting team on board.

Site Characteristics

As part of a fatal flaws or feasibility analysis, site characteristics should always be considered. Site characteristics that should always be included in any analysis include ground slope, topographic features, access to the site, path to potential interconnection point(s), existing vegetation, erosion potential and soil type. Analysis of environmental features along possible interconnection routes should be considered in addition to the array site itself.

Local Requirements

Do some research on property boundaries and easements, available mapping (wetlands, topographic, utility, endangered species), local by-laws (zoning, planning, and conservation).  Information obtained from the local conservation office, Town or City Engineer, or zoning office can be included in an RFP or made available for review prior to bid.

 State Requirements

A state environmental review (ie. Massachusetts Environmental Policy Act http://www.env.state.ma.us/mepa/ (MEPA)) may be required if the project meets a State’s “threshold” for review.  State thresholds should be checked to see if any project characteristics exceed the threshold.  If they do, a regulatory review may be required and possibly add 30-60 days minimum to the project timeline.  Most states maintain a free online database of environmental resources/protected areas, historic resources and hazardous waste or Brownfields sites.

For example, if the site is a landfill, the landfill must be closed, capped and in full compliance with State regulations.  A Post-Closure landfill use permit is likely required.  Talk to your state Department of Environmental Protection (ie. NHDES, MADEP).  Permits for post-closure landfill use can take 2-6 months.

Federal Requirements

A federal environmental review (National Environmental Policy Act http://www.epa.gov/oecaerth/basics/nepa.html (NEPA)) may be required if federal money is involved or if the project meets a federal threshold for review. As with state regulations, if any project characteristics exceed federal thresholds, they may trigger a regulatory review that will add to the project timeline.

Any site with over one acre of total land disturbance requires a National Pollutant Discharge Elimination System (NPDES) permit for erosion andstormwater pollution prevention. Easier than it sounds, this is a simple document that can be filed electronically and does not delay a project. Best practices, such as using silt fences or haybales around any open excavated areas, should be utilized.

Drafting a Request For Proposals (RFP)

Give the solar developer as much relevant information from your research as possible in the RFP, or provide a list of available resources to examine.  The more information the bidder has about environmental considerations, the more competitive and accurate the bid outcome can be.

Summary

An owner’s agent can assist in identifying potential feasibility issues and evaluate proposals for a PV system.   Factors to evaluate for a ground mounted system are different from a roof mounted system and include environmental considerations.  Proper planning and knowing what to expect help make the bid and project phases go smoothly.

 DOER filed a report with the Massachusetts Department of Public Utilities outlining recommendations for utilities to improve the process of connecting new renewable energy generation installations to the electric grid. In its filing, DOER attached the Massachusetts Distributed Generation Interconnection Report which surveyed customers seeking interconnection in the state, researched policies in other states, interviewed utilities, and made specific recommendations about improving interconnection processes and policies.

The status of progress on these issues and scheduling for distributed generation (DG) workshops is available at the Massachusetts DG and Interconnection Website (http://bit.ly/MADGIC).

 Many communities interested in renewable energy have questions and concerns about net metering and interconnection. This is particularly true among communities exploring landfill solar or community wind projects, which are largely dependent on the Massachusetts net metering incentive.

DOER has succeeded in getting a commitment from the Massachusetts utilities to host monthly distributed (on-site) generation workshops. These workshops will cover the basics of interconnecting distributed generation technologies in investor-owned utility territories in Massachusetts as well as other pertinent distributed generation topics, including net metering. The DOER’s Massachusetts Distributed Generation and Interconnection Main Page has more information about upcoming workshops, as well as links to presentation materials from past events. In addition, the DOER DG site provides additional resources on these topics, including the “Basics of Interconnection and Net Metering.”

Closed landfills are increasingly popular sites for community renewable energy projects.

The Department of Energy Resources (DOER) is expected to release a handbook on landfill solar PV in the upcoming months. This handbook is expected to include community-specific guidance on these increasingly popular projects.

For additional information on renewable energy at closed landfills, the Massachusetts Department of Environmental Protection (MassDEP) website currently hosts a number of resources.
