Cirro Energy serves over 150,000 customers through Smart Lock plans offering 12, 24, or 36-month fixed rates, with green energy integrated into every plan. While the company benefits from NRG’s Fortune 500 stability, customer feedback reveals mixed experiences—the Customer Service Score sits at 35/100 and Billing Clarity Score at 26/100, suggesting room for improvement in these areas despite the company’s emphasis on simplicity and transparency.
