What is RAP?
Retail Competition and Open Access allows qualified businesses to switch to renewable energy
Retail Competition and Open Access (RCOA) is a framework under the Electric Power Industry Reform Act of 2001 (EPIRA) that opens the electricity market to competition. It allows qualified businesses to move beyond their distribution utility and contract directly with a licensed Retail Electricity Supplier (RES) for their power supply.
Businesses with at least 500 kW monthly energy demand may participate in RCOA and source electricity through the Contestable Retail Electricity Market (CREM), where suppliers compete to offer more competitive rates.
This gives businesses the ability to select a supplier that aligns with their operational and business priorities. And with ACEN RES, this means sourcing 100% renewable energy from a single, integrated energy platform.
Seamless Switching
Making the switch to renewable energy is simple, without disrupting your operations allowing your business to run as usual.
No Upfront Investment
Get powered by renewable energy without rooftop solar panel installation and maintenance fees.
Predictable Power Costs
Businesses under GEOP are protected from price volatility unlike traditional power rates that are exposed to fuel price fluctuations and unexpected cost spikes.
