SOLAR FACILITIES
[Bill No. 37-2017[1]]
1. Editor's Note—This article was enacted as Article 4E. Because provisions regarding breweries were also enacted as Article 4E, this article was renumbered to avoid duplicate numbering and to maintain the organization of the Zoning Regulations.
A.
Purpose. Solar energy is recognized as an abundant, renewable, and environmentally sustainable source of electricity generation that will lead to greater local grid resiliency and security, and produce clean, renewable energy and reduce air and water pollution caused by the burning of traditional fossil fuels. The purpose and intent of this article is to permit solar facilities in parts of the rural and commercial areas of the County by special exception, and to balance the benefits of solar energy production with its potential impact upon the County's land use policies by ensuring sufficient safeguards are in place to protect the County's communities and its agricultural land, forests, waterways, and other natural resources.
B.
Application. In accordance with §7-218(b) of the public utilities article of the Annotated Code of Maryland, this article shall apply only to a solar facility that has the capacity to produce not more than one (1) megawatt of electricity as measured by the alternating current rating of the facility's inverter.
C.
Definitions. As used in this article, the following terms have the meanings indicated:
AGRIVOLTAIC — the simultaneous use of areas of land:
1.
That are maintained in agricultural use in accordance with COMAR 18.02.03;
2.
For both solar power generation and:
I.
Raising grains, fruits, herbs, melons, mushrooms, nuts, seeds, tobacco, or vegetables;
II.
Raising poultry, including chickens and turkeys, for meat or egg production;
III.
Dairy production, such as the raising of milking cows;
IV.
Raising livestock, including cattle, sheep, goats, or pigs;
V.
Horse boarding, breeding, or training;
VI.
Turf farming;
VII.
Raising ornamental shrubs, plants, or flowers, including aquatic plants;
VIII.
Aquaculture;
IX.
Silviculture; or
X.
Any other activity that is recognized as an agricultural activity under COMAR 18.02.03.
"Agrivoltaic" does not include the simultaneous use of areas of land for both solar power generation and:
1.
Apiaries; or
2.
Pollinator habitat.
COMMERCIAL USE — the transfer to the electrical power grid of energy produced by a solar facility for sale by energy suppliers to consumers.
SOLAR FACILITY — A facility that includes a series of one or more solar collector panels or solar energy systems that are placed in an area on a tract of land for the purpose of generating photovoltaic power for commercial use. The term includes a solar energy generating station, solar power plant, or solar photovoltaic farm.
