​​​​​Procuring adequate wholesale supplies of electricity at the best available price to serve our utilities’ Standard Offer Service (SOS) residential and commercial customers is a central responsibility of PHI and certainly a critical one. Our goal in the SOS Procurement and Wholesale Supplier Support sections is to enhance the ease and efficiency with which electricity suppliers doing business with Pepco—or who wish to do so—can submit their bids and applications, fulfill their contractual obligations and manage their invoices to and payment by PHI.
