Imagine you really want to play with a toy, but you don't have enough money to buy it. So, you ask your friend if you can borrow the money for the toy, and you agree to pay your friend back in installments over time.
That's kind of what a power purchase agreement (PPA) is like for electricity. Sometimes, a company that wants to use electricity doesn't have the resources to build its own power plant or install solar panels or wind turbines. Instead, they can enter into a PPA with another company that owns the power plant or renewable energy system.
The company that owns the power system agrees to sell the purchaser electricity at a fixed price over a certain period of time, usually several years. This is called a "contract term." During this time, the purchaser agrees to buy a certain amount of electricity, usually enough to power their buildings or operations or something equivalent to that.
The electricity, usually renewable or alternative energy, is produced by the company that owns the power plant or system, and the purchaser pays the owner for the right to use it. Think of it like a rental agreement, but instead of renting a building, the purchaser is renting the energy produced by the power system.
By using a PPA, the purchaser can get access to electricity that is produced in a more sustainable way than traditional fossil fuels, and they can do so at a predictable cost. It's like knowing how much allowance you'll get each week from your parents, so you can budget and plan your spending.
So, in short, a power purchase agreement is like borrowing money from a friend to buy a toy, but instead, a company borrows electricity from a power plant owner to power their operations, and they pay for it over time at a fixed price.
