* Battery storage projects costs vary depending on the power to energy ratio (also referred to as "duration"). The REopt model requires storage project costs to be input as two separate numbers, one for the power rating and another for the energy rating. These two cost variables are considered together in determining the optimal battery system configuration and, hence, the final project cost.
