The System Access Charge (SAC) helps keep the grid reliable and costs equitable for all MPE members.
The SAC is a fixed fee that every MPE member sees on their bill. It helps fund infrastructure, like poles, power lines, and meters, and their maintenance, alongside administrative costs and vegetation management. In other words, the SAC pays for the system that keeps your power reliable–running more than 99% of the time.
