The Lincoln Park Grid Support Center will use batteries to manage short-term changes in energy supply and demand. To use industry terms, the project will provide frequency regulation, spinning reserves and peaking power. The project is designed to increase local electric reliability and decrease carbon pollution.
Providing a reliable electric system involves more than just generating power. Electricity has to be available when its need and must meet strict quality requirements to prevent damage to the devices that depend on it. The Lincoln Park Grid Support Center is focused on providing these critical services and not solely on generating power.
Connection to the Grid
The Project will connect to Central Hudson Gas & Electric's existing Lincoln Park Substation. GlidePath will working with Central Hudson to upgrade existing poles to carry the new electric circuit required to add the Project (for the final portion of the route near the Project new underground or overhead lines will be required). The Project will connect to the distribution system, the same system that carries electricity from the substation to homes and business and not the high-voltage system. A map of the route with examples of the poles used is shown below.
About Reliability Services
Electric grids always need to have reserve power on-hand to manage the flow of electricity and prevent overloads and blackouts. The need for flexible power reserves is increasing today as we integrate more wind and solar generation into the grid.
The standard way to provide grid stability is to burn extra fuel at coal or gas plants when demand spikes or voltage drops. Typical power plants take up to 10 minutes to ramp up and down and consume a lot of fuel in the process. These plants might cover only a few spikes in demand during the day but they must continue burning fossil fuels 24/7 to stay online until they’re needed.
This inefficient approach increases air pollution and water usage and creates higher costs to consumers.
The Battery Advantage
Battery storage is a better way to manage variations in electric supply. The Lincoln Park Grid Support Center uses batteries to provide a cleaner and more efficient way to support the grid and integrate renewable energy.
The Grid Support Center’s batteries are charged by absorbing excess power from the grid. The batteries store power and discharge it to meet the grid’s requirements, eliminating the need keep fossil fuel reserves running. When demand spikes or extra power is required to balance the system, the batteries respond in seconds. This fast response reduces wasted power and creates a more stable supply of electricity.
Supporting the Transition to a Low-Carbon Grid
New York is a leader in aggressively transitioning to low-carbon electricity with its use of wind, solar and other renewable technologies. However, many of these types of generation are intermittent; they cannot produce power when the wind is not blowing or the sun is not shining. Projects like the Lincoln Park Grid Support Center will help bridge the gap when the generation from renewable resources is not sufficient to meet demand.
The services provided by the Lincoln Park Grid Support Center are essential to maintaining grid reliability and recovering from outages and other events that stress the power system. When constructed, the project will displace older and less-efficient providers of these services.
 Frequency regulation involves moment-to-moment reconciliation of the supply of electricity and the demand for electricity. The reconciliation is done every few seconds. If at any given moment electricity demand exceeds supply, the supply is increased to meet demand. If demand is less than supply, the supply is decreased. (Source: U.S. Dept. of Energy)
 Spinning reserves refers to online-but-unloaded generation capacity that can respond within 10 minutes to compensate for generation or transmission outages. ‘Frequency-responsive’ spinning reserve responds within 10 seconds to maintain system frequency. Spinning reserves are the first type used when a shortfall occurs. (Source: U.S. Dept. of Energy)
 Peaking power refers to electricity use at its highest points during a day. Day-to- day trends of power usage need to be met by power plants, but it is not optimal for power plants to produce the maximum needed power at all times. Peak load plants usually use old, low-efficiency steam units, gas turbines, diesels, or pumped-storage hydroelectric equipment. (Source: U.S. Energy Information Administration)
