About UVIG

The Utility Variable-Generation Integration Group, previously known as the Utility Wind Integration Group (UWIG), was established in 1989 to provide a forum for the critical analysis of wind and solar technology for utility applications and to serve as a source of credible information on the status of wind and solar technology and deployment.  The group’s mission is to accelerate the development and application of good engineering and operational practices supporting the appropriate integration and reliable operation of variable generation on the electric power system.

Did You Know – Market Challenges in the Ireland and Northern Ireland Power System

The Ireland (IRE) and Northern Ireland (NI) power system is a synchronous system of approximately 7,000 MW peak, with over 9,000 MW of installed conventional plant and almost 3,000 MW of wind.

There are currently two HVDC interconnectors to Great Britain totaling an import/export capacity from the island of up to 1,000 MW.  The system is operated by the EirGrid group, which is the transmission system and market operator on the island.  The market arrangements are jointly regulated by the Utility Regulator (NI) and the Commission for Energy Regulation (IRE).

In 2016 the power system is already dealing with pioneering levels of variable non-synchronous generation, including wind.  This has resulted in real-time penetration levels of these technologies on occasion reaching 55% of the total synchronous area.  In addition, the policy objectives will see these levels rise. The goal is for 40% of electricity consumption to come from renewable resources (mainly wind) by 2020.  To efficiently accommodate this, real time levels up to 75% of the total synchronous area will have to be managed securely and reliably.

U.S. Department of the Interior Releases National Interactive Map of Onshore Wind Turbines

The U.S. Department of the Interior and U.S. Geological Survey have released the first publicly available interactive map and geo-dataset showing more than 47,000 onshore wind turbine locations and related information across the entire United States

The wind turbine map, which includes turbines installed as of July 2013, was created by combining publicly available data sets from the Federal Aviation Administration , the U.S. Energy Information Administration , the Oak Ridge National Laboratory , as well as other federal, state and local sources. USGS researchers also identified additional turbines not in those pre-existing databases and added them to the dataset and map. The locations of all turbines were visually verified using high-resolution imagery. The location of each turbine was verified to within plus or minus 10 meters, and its technical specifications were assigned based on the make and model.

Why Join UVIG?

Featured Member Benefit

One of the key benefits of UVIG membership is participation in our User Groups. UVIG operates five topical user groups focused on specific areas of interest to its members:

  • Wind and Solar Plant Modeling and Interconnection
  • Operating Impact and Integration Studies
  • Distributed Generation Applications
  • Market Operation and Transmission Planning
  • Wind/Solar Plant Operations and Maintenance

These groups are open to all UWIG members (there are participation limitations for the O&M User Group). The concept is to gather together in one place all relevant information on that topical area, and make it easily available to the members. This information is housed in the member’s area of the site. Each user group has a listserv or mailing list that we use to distribute news, research reports, future events, and other information relevant to the user group’s scope. Because the User Groups cut across multiple groups within any company, we would like to encourage you to identify other individuals in your company who could benefit from participation in a User Group.  To subscribe yourself or others with your company to any of the user group listservs, please contact Sandy Smith, sandy@variablegen.org. Note that only those members that own/operate wind or solar generation can participate in the O&M listserv.
