market in 2021 having currently installed solar SCADA systems, and there are likely additional firms operating on a regional basis around the country. There are at least five solar SCADA specialist firms operating in the U.S. Similar to the groupings of SCADA providers in the wind sector, there are four major types of solar SCADA offerings for the U.S. The more than 2500 utility-scale solar farms operating in the United States also have a requirement for SCADA systems. Included here are large companies such as ABB and Schneider, as well as key suppliers to the mid-size utility market and include firms as ACS-Indra, OSI, QEI, Survalent, and others. Most of these firms have now developed requisite software or have partnered for development of wind energy applications, and have likely implemented wind applications for one or more utility customers at this point in time. The fourth group of offerings that have made some inroads with utility-operated wind farms is provided by the "traditional" suppliers of electric utility SCADA, DMS, and energy management systems. Products from leading suppliers including PcVue, Iconics, Wonderware (Aveva), and others have all been successfully applied to numerous wind farms in the United States and elsewhere. The third group of wind SCADA offerings comes from "generalist" SCADA suppliers, those companies that provide packages or configurable SCADA to multiple industries, from energy utilities to process industries to discrete product manufacturers and commercial building control systems. Status reporting, turbine condition assessment, and activity controls can be accomplished by the SCADA offerings from these suppliers, regardless of the turbine type, size, or manufacturer. ![]() Offerings from these firms enable wind farm operators having wind turbines acquired from multiple suppliers to work in an integrated manner, analogous to a substation automation system that has to coordinate among multiple protective relay suppliers. The second group of wind SCADA offerings is provided by a number of wind technology specialist firms, including DEIF, Grantek, Halus, and SCADASolutions. The SCADA offerings from these firms appear to be designed with current generation software platforms and incorporate some useful apps development tools - an optimal solution for those sites that make use of wind turbines from a single manufacturer. The SCADA applications developed by each turbine manufacturer center around wind turbine controls, but the offerings also extend to include a bevy of related monitoring and control applications for commercial wind farms. presence and current installations around the country. wind turbine sales) and supplemented with some Chinese manufacturer installations and supporting control systems software from either Goldwind or Envision, both of which have a U.S. market, including GE, Siemens, and Vestas (collectively representing about three-quarters of U.S. The first group of wind SCADA offerings comprises the leading wind turbine manufacturers for the U.S. ![]() There are four types of SCADA providers serving the wind power industry as shown here: For enterprises operating multiple facilities, capabilities exist to coordinate multiple SCADA installations (or site automation/control systems) under the control of a larger company-wide or utility-wide SCADA system. There have been a number of larger solar plants coming onstream in the last five years.Įach of these 4000-plus utility-scale renewables sites now operational in the United States requires a SCADA-like system to acquire operating information and to coordinate grid planning activities. Most of these facilities represent from 1 MW to 5 MW of generation capacity. Department of Energy's (DOE's) Energy Information Administration (EIA), there are more than 2500 utility-scale solar plants/farms now operating in the United States. The country is adding about 3000 utility-scale wind turbines each year.Īccording to the U.S. These thousands of wind turbines are installed at about 1500 sites or farms. ![]() Department of the Interior’s USGS agency reports that there are about 67,000 large (utility-scale) wind turbines in operation in the United States.
