Every day more corporations buy clean energy to power their operations, aiming to reduce their carbon emissions and to control their energy costs. Many find that first goal to be easier than the second.

Through vPPAs, corporate clean-energy buyers can make a lot of money or lose a lot of money in what, for many buyers, amounts to a bet on future power prices and the weather, but there are ways to reduce or minimise that risk.
