Can energy storage be configured to manage export?
Energy storage systems can be configured to manage export. When used to limit or shape export, storage allows developers to increase nameplate capacity or decrease exports without triggering additional grid impacts. Export-limited systems may qualify for simplified interconnection.
Can energy toolbase accurately calculate exported energy?
Note: Energy Toolbase can only accurately calculate exported energy if a user references an ‘Energy Use Profile’ that has interval meter data. If you reference an ‘Energy Use Profile’ using monthly summary data, we simply assume that inputted kWh energy usage is evenly distributed throughout all intervals in a billing cycle.
How do I calculate the 'avoided cost' or 'value of solar'?
Calculating the ‘avoided cost’ or ‘value of solar’ requires calculating how much energy (kWh) gets exported to the grid. On the ‘Edit Proposal’ screen, users can reference how much energy is exported in % terms inside the ‘Meters’ section.
What happens if you overstate energy export values?
Overstating export values can result in unnecessary upgrade costs or delays. Energy storage systems can be configured to manage export. When used to limit or shape export, storage allows developers to increase nameplate capacity or decrease exports without triggering additional grid impacts.
What is the difference between imported energy and exported energy?
During the day when the sun is shining, imported energy would occur when the facility is using more energy (kWh) than the PV system was generating. Exported Energy, measured in kWh, is energy that is back-fed to the grid. In other words, the solar system was producing more energy (kWh) than the facility was using, during a given interval.
What is export capacity?
Export capacity refers to the maximum amount of power a system is allowed to export to the grid at any given time generally through a set of relays and program settings. This value is often regulated through interconnection agreements, and it may be significantly lower than the system’s nameplate rating.
