You'll need to:

• Review contract terms and lengths (3-36 months)
• Consider renewable energy options
• Check for additional fees
• Sign a Letter of Authorization

The switch won't interrupt your service, and your new supplier will handle the transfer with your utility company.

Your new rate will take effect in the next billing cycle.

New Castle's deregulated electricity market

After Delaware deregulated its electricity market in 1999, the state transformed how residents and businesses purchase their power.

The system now operates with three distinct components:

• Generation: Power companies produce electricity and sell it in the wholesale market
• Transmission: Utilities maintain the high-voltage power lines that transport electricity
• Distribution: Local utilities like Delmarva Power deliver electricity to your home

Many retail suppliers compete for your business and offer various rate plans. If you don't select a supplier, you'll automatically receive default service through your utility provider.

The Public Service Commission continues to regulate distribution services, ensuring reliable power delivery.
