APX Power Markets, Inc.

We integrate third-party forecasts with the APX MarketSuite^® to automate ISO scheduling of intermittent resources, including the most current forecast updates prior to the adjustment period deadline. This is a cost-effective, labor-saving solution for scheduling resources and complying with ISO programs. For this reason and many others, more wind generators today are turning to the APX MarketSuite^®.

More than 7,000 MW of generation, the majority of non-utility owned merchant generation in ERCOT, are currently telemetered and controlled by APX systems. APX offers a hosted Supervisory Control and Data Acquisition (SCADA) solution integrated with the APX MarketSuite^® for scheduling, operations, and settlements in ERCOT. Additionally, clients can monitor resources using a web browser and access historical data. This integrated solution provides a cost-effective and reliable alternative by eliminating the complexity, cost, and project risk for generators, as well as dispatchable loads participating in ISO demand response programs.

The APX MarketSuite also provides a cross-market scheduling API for a single point of integration to many ISO regions and web services for a machine-to-machine interface for downloading files and data.

Benefits include:

• Fast track setup coordinating with third parties, the resource facility, and ISO
• No large implementation, operations, and maintenance costs
• Compliant with ISO and/or NERC regions
• Extensive in-house technical support team
• Advanced automated processes
• Additional 24/7 operations monitoring through APX Operations Center
