The most effective long-term hedge against rising energy prices is to generate some of your own power. On-site solar reduces how much you buy from the volatile grid, and a fixed PPA rate locks in a large part of your cost — giving years of budgeting certainty with no upfront outlay.
Why grid prices are so volatile
Business electricity prices track wholesale energy markets, which swing with global events, supply and demand. That leaves firms exposed to sharp, hard-to-budget increases — a real risk for energy-intensive operations.
Generating your own power
Every unit you generate on site is a unit you don’t buy at the mercy of the market. Solar therefore acts as a partial hedge, shrinking your exposure to price shocks for decades.
A fixed rate for certainty
Under a PPA you pay a fixed, predictable rate for your solar — typically guaranteed below the grid — so a significant part of your energy cost stops moving with the market. That certainty is valuable in itself.

Frequently asked questions
Does solar fully protect us from price rises?
It reduces your exposure by cutting how much you buy from the grid, and a fixed PPA rate locks part of your cost. You still buy some grid power, but a much smaller, less volatile amount.
What if energy prices fall?
A well-structured PPA is designed to stay below grid rates, and you keep the benefit of self-generation regardless. We explain exactly how the rate works before you commit.
