A ramp rate limits how fast your battery changes its power
A ramp rate defines how fast your battery may increase or decrease its power, in percent of installed capacity per minute. Stricter ramp rates reduce how quickly a battery can respond, which limits energy delivery and revenue potential. Your grid operator decides whether the limit applies to wholesale trading only or to balancing services as well. Its cost is highest where it applies to automatic frequency restoration reserve (aFRR) energy delivery.
One setpoint per delivery period instead of a return to zero
Most batteries use trapezoidal dispatch: they ramp back to zero at the end of every 15-minute delivery period and then up again for the next. The energy lost in those dips is energy your battery can’t trade. Entrix Smart Dispatch keeps your battery at its setpoint across consecutive periods and moves smoothly from one to the next. Because we plan neighboring periods together, your battery gets more out of every period within the ramp rate limit. Where a short-term price spread is worth more than holding the setpoint, the algorithm takes it.
A smoother profile is better for the grid
Fewer returns to zero mean fewer power jumps at your grid connection. That gives you a strong argument when your grid operator considers a strict ramp rate limit.
