Repsol Renewables North America is wholly owned by Repsol, a global multi-energy company that leads the energy transition and has set itself the goal of being zero net emissions by 2050.

Solar photovoltaic (“PV”) panels typically consist of tempered glass, aluminum, copper, and semiconductor materials. Semiconductor materials have has conductive properties that allow it to absorb and convert sunlight into electricity. Upon interaction with light, electrons are set into motion, which initiates a flow of electric current in a process known as the “photovoltaic effect.”1

A solar farm is a large group of solar panels that operate together as one power generation facility, delivering electricity to the existing electric grid. Solar farms are typically arranged in parallel rows with approximately 8 feet wide access buffers between each row.

A panel array, which includes both PV panel and rack mounting, typically stands around 12 feet tall. The mounting racks are supported by steel pile foundations generally set up to 8 feet into the ground without the use of concrete. Panel designs currently being evaluated by Repsol Renewables North America include single-axis tracking mounting, which rotate slowly from east to west once a day, keeping the sun at a 90-degree angle from the panels to ensure maximum energy is absorbed. Repsol Renewables North America monitors technology improvements, and will incorporate improved design as appropriate which may affect solar array dimensions. Each section of solar panels is typically fenced off to ensure security and safe operation.

Other project infrastructure present at a solar farm includes common electrical equipment such as inverters and transformers and the electrical equipment necessary to deliver energy to the existing electrical grid such as underground and overhead transmission lines.

New York State requires that major renewable energy facilities, including solar farms with a nameplate generation capacity of 25MW or more, undergo a rigorous state permitting process, prior to construction and operation. The Mill Point Solar I Project will obtain a Siting Permit from the Office of Renewable Energy Siting (ORES) in accordance with new regulations promulgated pursuant to New York State Public Service Law Article VIII. ORES will establish Uniform Permit Standards and Conditions outlining rigorous requirements for the study of the environmental, public health, and public safety impacts as well as the incorporation of extensive public input and local stakeholder engagement into the development, design, and construction of solar energy projects like the Mill Point Solar I Project.

Repsol Renewables North America expects to pay more than $2.5 million per year directly to Glen landowners through lease, easement, and neighbor agreements. These landowners, in turn, will use this money to reinvest in new farm equipment or home improvements, which will generate additional income for the County in assessed property taxes and sales tax.

Additionally, Repsol Renewables North America is contractually obligated through its contracts with NYSERDA to provide over $17.5 million of in-state economic benefits to New York within the first 3 years of project operation alone. These benefits include in-state construction labor, landowner payments, Payment in Lieu of Taxes (PILOT) and Host Community Agreement (HCA) payments, local equipment and materials purchases, local sponsorships and donations, and full-time operations jobs.

Further, the Mill Point Solar I Project represents an approximately $350 million capital investment, which will bring significant revenue, jobs, and economic development into the Town of Glen and Montgomery County. The Project will also result in significant annual revenue to the Town of Glen, the Fonda-Fultonville Central School District, and Montgomery County without burdening existing resources. It is estimated that through the PILOT agreement and HCA, the project will provide additional tax revenues, which could total more than tens of millions of dollars over the life of the project.

Solar projects are low impact and coexist well with agriculture, operating without any impact to adjacent agricultural properties. During the solar project’s 30 year or more lifespan, the land hosting the project gets a recovery period, allowing the soil to restore fertility and rebuild. Native vegetation can grow under the panels, allowing the land to retain water and topsoil and improving soil health over time, which can increase the productivity and value of the land for agriculture in the future.

The construction, post-construction restoration, and decommissioning of the Mill Point Solar I Project will be conducted in accordance with the New York State Department of Agriculture and Markets “Guidelines for Solar Energy Projects – Construction Mitigation for Agricultural Lands” to mitigate construction impacts to agricultural land. Further, Repsol Renewables North America will have a Stormwater Pollution Prevention Plan (SWPPP), which will outline Repsol Renewables North America’s plans for sediment and erosion controls to manage both the amount and composition of any stormwater discharged from the project site. There are no anticipated stormwater runoff issues for land hosting or adjacent to panel areas.

At the end of the solar project’s useful life, the project is decommissioned, and the land can be returned to agricultural use.  In addition, a solar project can offer a consistent, weather-resistant source of income for rural farmers and their local economies, providing an alternative “crop” that diversifies farmers’ revenues.

Solar power is now one of the cheapest new sources of electricity in most of the world due to declining equipment costs, improved technologies, and public policy supporting the procurement of renewable energy across the country.2

In the last decade, the cost to install solar has dropped by more than 70%, and as of Q3 2020, prices are at their lowest historical level across all market segments.3 According to Lazard’s Levelized Cost of Energy Analysis – Version 14.0 (2020), even without tax credits, new solar resources have a levelized cost of energy in the range of 3.1¢/kWh – 4.2¢/kWh for large-scale crystalline solar. This range falls below the levelized cost of energy for new coal or gas combined cycle power production.4 These results have been bolstered by the International Energy Agency’s World Energy Outlook 2020,5 which found that “For projects with low-cost financing that tap high-quality resources, solar photovoltaic (PV) is now the cheapest source of electricity in history.”6

Adding to the growing appeal, solar energy is uniquely able to offer electricity at a fixed-price contract over the life of the project. Solar energy has no fuel cost and therefore no fuel price risk, allowing it to act as a hedge against future volatility of natural gas prices.7 Levelized power purchase agreements for commercial-scale solar projects fell to $24/MWh in 2019, down 17% from 2018 and more than 80% since 2010.8

Yes, this solar project will pay millions of dollars in taxes starting on day one of operation and continuing throughout the life of the project.

Repsol Renewables North America will be fully responsible for maintaining the solar farm and associated equipment, as well as the property within the Mill Point Solar I Project’s boundaries. Landscape maintenance at the solar farm will be performed by companies contracted directly by Repsol Renewables North America.

Yes. Solar panel materials are enclosed with glass and do not mix with water or vaporize into the air, so there is little to no risk of chemicals, including greenhouse gases, being released into the environment during normal use.

Electric and Magnetic Fields (EMF) are present everywhere in our environment, including TV antennas, radio signals, Wi-Fi, cell phones, and common household appliances.9 EMF emissions from solar panel systems are non-ionizing and in the same extremely low frequency range as those induced by household appliances.10

All solar facilities are designed to strict electrical safety standards to ensure safe operation. Product safety standards, installation requirements, and building codes for solar facilities are addressed by the National Fire Protection Agency’s National Electrical Code, the International Code Council’s International Fire Code, the International Association of Firefighters, and several other national, state and local safety and product standards groups.11

Solar farms are designed with lightning protection on all system components, which protect against damage in the event of a lightning strike. The ground grid will be designed in consideration of the conductivity of soils in the area as well as any other nearby conductive materials that are buried or connected to the ground, such as water or natural gas pipes.

Temporary, elevated noise levels may occur during the construction phase of a solar farm, but once construction is complete, an operating solar farm emits minimal noise during the day and is dormant at night. Repsol Renewables North America is committed to taking steps to minimize and mitigate visual impacts of the project through vegetative buffers and setbacks from property lines, which will provide additional sound dampening benefits, as well.

Repsol Renewables North America’s lease agreement states that the company is responsible for the decommissioning and removal of project infrastructure at the end of the project’s life.

Additionally, New York State will require a Decommissioning and Restoration Plan be put in place as part of the state Article VIII permitting process. The Decommissioning and Restoration Plan will outline the various ways in which Repsol Renewables North America will safely and responsibly remove installed solar equipment and how the property within the project area will be restored to as close to its state prior to construction as possible. As required under Article VIII and the Town of Glen Solar Law,12 Repsol Renewables North America will put financial security in place early in the life of the project to ensure that host communities and landowners will bear no responsibility for decommissioning or restoration.

The construction of the Mill Point Solar I Project will not require toxic chemicals or processes. PV panels typically consist of glass, aluminum, copper, silver, and semiconductor materials that can be successfully recovered and reused. Solar panel materials are enclosed with glass and do not mix with water or vaporize into the air, so there is little to no risk of chemicals, including greenhouse gases, being released into the environment during normal use. Crystalline silicon PV panels, which represent approximately 90% of the solar panels in use today, “do not pose a material risk of toxicity to public health and safety.”13

In addition, to provide decades of corrosion-free operation, panels – like the ones that will be used for the Mill Point Solar I Project – are encapsulated from air and moisture between two layers of plastic. The encapsulation layers are further protected with a layer of tempered glass on the front and a polymer sheet on the back. For decades, this same material has been used between layers of tempered glass to give car windshields and hurricane windows their great strength, allowing them to stay intact even if damage occurs.

Repsol Renewables North America expects to site project components on approximately 1,040 acres for the Mill Point Solar I Project, wholly located within the Town of Glen. Construction of solar projects is generally low impact and does not typically require significant site work or soil disturbance. Repsol Renewables North America aims to further minimize potential environmental impacts by avoiding wetlands, limiting tree clearing, and working with participating farmers to utilize less productive agricultural fields.

Solar power is a reliable source of energy, with solar projects being installed in all 50 states across the US.14 New York State, which has a considerable amount of solar potential, has consistently been in the top 10 US solar markets and is projected to install 4,367 megawatts (MW) over the next five years, all above the 40th parallel.15

A solar project will produce power most days of the year, even under cloudy conditions, and in some cases, clouds can result in better panel performance. Further, a recent industry trend is the use of bifacial solar panels, which have solar cells that capture sunlight from the front of the panel as well as sunlight that is reflected off the ground. These panels have been shown to yield 11% more energy than standard solar panels in a tilted, ground-mounted solar installation.16

No electricity source runs 100% of the time, including coal, gas, and nuclear plants. While solar is variable as a power resource, its variability can be predictably forecast and used to complement other generation sources. Grid operators have decades of experience managing changes in supply and demand, including the gradual, predictable changes in solar output.17

Solar projects do not burn fossil fuels to generate electricity, and as a result, do not emit any air pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, or particulate matter. Both fossil fuel and non-fossil fuel power technologies induce life-cycle greenhouse gas emissions that stem from the energy requirements for their construction and operation. Known as a “carbon debt”, this debt of energy must be paid off to calculate how solar projects reduce emissions over their lifetime. A typical utility-scale solar project repays its carbon footprint in roughly 12 months or less,18 allowing them to provide decades of zero emission energy.

Prior to operation, we will develop an Emergency Response Plan in accordance with industry best practices, which will outline the response procedures to be employed should an emergency arise at the project site. We will work closely and collaboratively with the local departments and authorities. We provide pre-construction training to all emergency response personnel, which includes a description of the facility, any potential construction risks, and the role of emergency responders should an incident occur. After construction is complete, we will host the emergency response personnel for a site visit to make sure they are familiar with the system and our Emergency Response Plan.

No. Property value studies conducted across the country have shown that proximity to large-scale solar projects does not measurably impact property values or deter the sale of agricultural or residential land.19 For example:

  • In 2017, the Chisago County (Minnesota) Assessor’s Office conducted their own study on property prices adjacent to and in the close vicinity of a 1,000 acre North Star solar farm in Minnesota. John Keefe, the Chisago County Assessor, concluded that the North Star solar farm had “no adverse impact” on property values. Almost all of the [Test Area] properties sold were at a price above the assessed value. He further stated that, “It seems conclusive that valuation has not suffered.20
  • In 2021, Kirkland Appraisals, LLC researched solar farms in Ohio as well as other states, researched studies and articles, and talked with real estate professionals. He found no negative impact in home values due to abutting or adjoining a solar farm, as well as no negative impact to abutting or adjacent agricultural land. He also noted that some of the positive implications expressed by people living next to solar farms include protection from future residential developments or other intrusive uses, reduced dust, odor and chemicals from former farming operations, protection from light pollution at night, it’s quiet and there’s minimal traffic.21
  • A study of 451 solar farms in North Carolina found “no direct negative or positive spillover effect of a solar farm construction on nearby agricultural land values. Although there are no direct effects of solar farms on nearby agricultural land values, we do find evidence that suggests construction of a solar farm may create a small, positive, option-value for landowners that is capitalized into land prices. Specifically, after construction of a nearby solar farm, we find that agricultural land that is also located near transmission infrastructure may increase modestly in value.”22

If sited and developed properly, the Mill Point Solar I Project will have minimal impacts on local wildlife. In fact, studies show that solar facilities can provide shelter for species, promote land stability, preserve habitat, and support biodiversity.23

As part of the New York State siting process, the Mill Point Solar I Project is consulting with state and federal agencies and stakeholders, including the Office of Renewable Energy Siting, NYS Department of Public Service, NYS Department of Environmental Consideration, NYS Department of Agriculture and Markets, and the U.S. Fish and Wildlife Service to ensure that potential environmental impacts are fully considered. Studies to help assess potential impacts include a noise impact assessment, seasonal avian studies, sensitive wildlife surveys, wetland and habitat delineations, and a wide range of other studies and surveys. The information gathered from this comprehensive coordination and review is used to inform final siting and design as well as various resource management plans and environmental protection measures to avoid, minimize or mitigate impacts to wildlife.

Once constructed, the Mill Point Solar I Project will produce no pollution or emissions. Further, native vegetation can grow under the panels, and the project can provide sanctuaries for flora and fauna to thrive.24 Vegetation management concepts, such as integrated vegetation management and pollinator friendly practices, provide opportunities to promote beneficial plants species and enhance habitats on the site.

Fencing, a security measure put in place in accordance with industry best practices, will be limited to areas around panels. Collection easements between panel areas will not be fenced to allow larger wildlife to traverse through the Project Area without disruption.

Yes. During construction, Repsol Renewables North America will coordinate with participating landowners to ensure that hunting activities are conducted in a safe manner while construction workers are on-site. Once operational, hunting will no longer be allowed within panel areas, but landowners will be able to hunt on parcels around the project area without restriction. Limited fencing, a security measure put in place in accordance with industry best practices and local requirements, will be erected around panel areas. Collection easements between panel areas will not be fenced to allow wildlife to traverse these corridors without disruption.

Repsol Renewables North America will develop and implement a Vegetation Management Plan that establishes vegetation goals and identifies the specific treatments that may be used to ensure safe and reliable operation of the facility. Common practices to control and manage vegetation will involve mechanized and agrarian means; however, herbicides may be employed, depending on the target plant species, land use activities and landowner input. Repsol Renewables North America is committed to the conscientious use of appropriate management techniques to control vegetation in a way that is designed to minimize the risk of unreasonable adverse effects on human health and the environment.

PV panels are designed to last more than 25 years, and many manufacturers offer performance guarantees backed by warranties.25 Repsol Renewables North America anticipates that the panels used for the Mill Point Solar I Project will have a useful life of at least 30 years. Like many other durable products and construction materials, solar equipment can last for decades with proper maintenance, of which they require very little due to the presence of very few, if any, moving parts.26 Proper operations and maintenance can increase efficiency, extend a project’s lifetime, and ensure safety.27 Prior to construction, the Mill Point Solar I Project will develop and implement an Operations and Maintenance Plan based on industry best practices and site-specific environmental conditions.

Solar PV panels typically consist of glass, polymer, aluminum, copper, and semiconductor materials,28 which can be safely disposed of in landfills at the end of the project life. In addition, recycling technologies have emerged in the last several years that have enabled these materials to be recovered and recycled at the end of their useful life.29 PV solar panel recycling technologies have been put in place over the last decade that have been shown to recover over 95% of semiconductor materials and over 90% of the glass in the panel.30 In other cases, solar PV components can be reused or refurbished to have a “second life” of generating electricity.31 The industry continues to work with recycling partners and to research and explore additional cost-effective recycling technologies.32
