Open Access Technology International, Inc. (OATI) and Arizona Public Service Company (APS) moved into Production Operation with a one-stop, integrated commodity trading and risk management system.
Minneapolis, MN: April 21, 2016 – OATI is pleased to announce APS successfully deployed the comprehensive OATI Energy Trading and Risk Management (ETRM) software solution in April 2016. The OATI ETRM solution provides APS with deal capture, scheduling, accounting, and risk management capabilities for power, natural gas, and emissions. By utilizing a single solution for their resource operations, APS, the largest electric utility in Arizona, will gain operational efficiency and transparency, as well as the ability for multiple business units within the organization to access the same data at the same time.

APS implemented OATI webRisk, a comprehensive market and credit risk solution for assessing, hedging, and modeling risk, to assure accuracy and transparency of energy trading portfolios. Based on a two-factor price mean reverting model with an added seasonality function, OATI webRisk is designed specifically for the energy trading market. The solution also features OATI webTrader, a streamlined energy trading platform, and OATI webCTRM, a tool for managing forward exposure in financially-oriented commodity markets. These integrated applications equip APS with a full ETRM system that covers front, middle, and back office needs.

“The APS and OATI Project Teams collaborated on defining and deploying solutions to meet challenging business needs, forming a partnership approach throughout the duration of the project,” said Jerry Dempsey, Senior Vice President of Sales and Marketing at OATI. “The breadth of the OATI solution provides APS with efficiency gains to aid in their business moving forward well into the future.”

APS, Arizona’s largest and longest-serving electricity utility, provides retail electricity service to nearly 1.2 million homes and businesses in 11 of the state’s 15 counties.
