TULSA, Okla., Jan. 8, 2010 – Public Service Company of Oklahoma (PSO), a subsidiary of American Electric Power (NYSE: AEP), is asking the Oklahoma Corporation Commission (OCC) to approve plans that will provide customers options for purchasing more renewable energy.

PSO is also asking the Commission allow the company to offer incentives to encourage manufacturers of wind and solar equipment to locate in Oklahoma.

In separate filings, PSO has proposed the Commission approve the company’s proposed Green Energy Choice tariff, and Wind and Solar Manufacturer tariff.

The Green Energy Choice tariff would create a voluntary program for customers who want to sign up for renewable energy. Currently, PSO customers get approximately 12 percent of their electricity from the nearly 600 megawatts (MW) of wind power PSO has under long-term contract. However, with the Green Energy Choice tariff, customers would be allowed to sign up for additional wind power in blocks of 100 kilowatt-hours (kWh), up to 2,000 kWh per month.

“Many of our customers have expressed a desire to have more of their energy come from renewable resources,” said Kathy Champion, PSO’s manager of consumer programs. “In addition, many of our cities and businesses have also expressed an interest in having an increased amount of their electricity supplied with renewable resources. The Green Energy Choice tariff will give customers that choice by allowing them to specify their preferred number of fixed kilowatt-hours and subscribe to that level.”

Customers who sign up for additional wind energy would pay $2.85 for every 100 kWh subscribed under the Green Energy Choice tariff.

The Wind and Solar Manufacturer tariff would allow PSO to offer a three-year discount on electricity for wind or solar equipment manufacturers to expand or locate new production facilities in PSO’s service area.

“PSO’s proposed initiatives seek to capitalize on Oklahoma’s abundant wind and solar resources, as well as the state’s central location in the nation to attract manufacturers of wind and solar industry equipment,” said Janet Smith, PSO’s manager of economic development.

The Wind and Solar Manufacturer tariff would apply to businesses that are primarily engaged in the production of wind and solar equipment, including wind turbines, solar cells and various components.

As of now, there is no specific timetable for the OCC to act on PSO’s proposals, although the company is hoping for approval in the next few months.
