Energy

The power bill in Puerto Rico is among the most expensive and the hardest to read. The price per kWh is not the published base rate: it moves with fuel adjustments, and to find yours you divide the bill total by the kWh you actually used.

With that number, these calculators tell you in dollars what the air conditioner, the dryer or the fridge is costing you, what a generator burns through a long outage, and whether a solar system pays for itself out of what you would stop paying.
