The 100% Renewable Energy charge (currently 3.98/kW) could potentially change once a year. The premium will be updated annually to ensure it reflects the current market value of the renewable energy certificates. You will receive advanced notice of price changes. Also, the total amount of the charge will fluctuate because it matches the total energy you’re using in your home or business each month. The average residential customer uses 1,000 kWh each month and would pay about $3.98, but you may use more or less energy than average. As a result, your charges will be higher or lower than this amount. This extra charge will appear on your monthly bill as 100% Renewable Energy (RIDER TRG). It may take up to one billing cycle to complete your enrollment.
