Massachusetts is the new hot bed of ground based solar PV projects in the Northeast. The recent SolarREC carve out from the already aggressive Renewable Portfolio Standards, along with Municipal Net Metering, has created an all-out sprint to the finish line of 400MW of solar. The value of the auction floor of SolarRECs at $0.30 kWh has spurred unprecedented growth in the PV marketplace.
Solar Developers throughout the US and some foreign countries are getting in on the action for the new wave of Renewable Energy – Commercial Scale Ground Based Solar. Almost every municipality in the Commonwealth appears interested in ground mounted solar PV, and many are entertaining the option of Power Purchase Agreements (PPA) to limit risk while avoiding capital investments. Development of large scale renewable energy projects, including solar PV, is assisting municipalities by reducing their annual energy expenses and serving as a hedge against continued volatility in the energy sector.
Before a PPA can be finalized or construction may begin, regulatory permits must be secured and the design finalized. The importance of these steps are often underestimated or in some cases, completely overlooked. Regional Planning commissions are receiving inquiries from member communities and have started analyzing the benefits and optimization of an aggregated approach.
Similar studies have been performed by Meridian Associates, Inc. for regional planners such as Merrimack Valley Planning Commission and the Metropolitan Area Planning Council on a regional basis to maximum potential for ground-mount solar photovoltaics and wind power. “As civil engineers, we deal with land use and permitting daily, it is necessary and appropriate to perform due diligence to identify potential fatal flaws for any given use, including solar” according to Meridian Associates Principal Richard Waitt, Jr., PE.
Solar Developers are finding that land use considerations add a level of complexity unrelated to their experience with installations of building mounted solar PV systems. Delays may result from a lack of understanding of land use considerations and can cost the project proponent unanticipated time and money.
Permitting a commercial scale system requires the expertise of land use professionals. Land use restrictions require research and experience to determine potential impacts on the development and grid connection of a solar array. Such restrictions include easements, deed restrictions, hidden subsurface utilities, stormwater surface runoff and flood plains, use restrictions, grid interconnection/access, title ownership, zoning restrictions and other regulatory controls.
Title and ownership issues must be vetted prior to design to ensure that there is clear title to the land, and that the parcel is not subject to easements or other encumbrances that may interfere with construction or long term operation. Rick Waitt states that “Potential land use restrictions should be evaluated to insure compliance with regulating limitations and to avoid conflicts with ownership or deed restrictions.”
Environmental regulations require protection of natural resources such as wetlands and endangered species habitats, which may preclude any development on the site. Flood Zones, drainage design, access to the site including roadways and utility infrastructure, require design calculations to ensure that the removal of vegetation and the introduction of impervious surfaces will not create a burden to abutting or downstream properties. Securing regulatory permits may be as challenging as other commercial land developments.
Many ground based projects in the Commonwealth have never reached the construction phase because of inadequate due-diligence, design or the permitting process. Maintenance, insurance and risk must be factored into the project pro-forma prior to submission to ensure a PPA that will work for both parties.
