Capacity: Project nameplate capacity. Unless otherwise stated, ACP reports capacity in MW-ac.
Duration: The amount of time, in hours, a battery can discharge its power capacity before depleting its energy capacity. For example, a 2 MW battery that has 4 MWh of energy capacity has a duration of 2 hours.
Full repowering: Full decommissioning of a utility-scale project. The original equipment is physically removed from the project site and replaced with new utility-scale equipment.
Inverter Loading Ratio (ILR): The ratio of installed DC capacity to the inverter’s AC power rating. Also known as the DC-to-AC ratio.
Partial repowering, nacelle replacement: Complete replacement of a utility-scale wind turbine’s nacelle, rotor, and blades. The tower and foundation are retained.
Partial repowering, major retrofit: Complete replacement of a utility-scale wind turbine’s rotor and blades, along with the replacement of at least one major component within the nacelle, typically the gearbox or the generator.
Pipeline: Projects either under construction or in advanced development.
Repowered: Full or partial equipment replacement. Currently only wind repowering activity is tracked, but ACP will expand repowering activity tracked as the market progresses.
