Strategic Group MappingAccording to Michael Porter who developed the concept of a “strategic group”, this is used in strategic management to group companies within an industry that share business models or combinations of similar strategies. The main goal of the concept is to help identify direct competitors and how they directly compete with the company. Strategy mapping can also be used to identify opportunities. In 2006, the Chinese government enacted a renewable energy law with the goal of directly supporting the growth of clean energy companies (Bradsher 2010). Companies that fall into the strategic group along with NRG Energy include Camco International, Canadian Solar, Inc. (CSI), China Biodisel International and China Sun Biochem. Camco specializes in assisting industrial companies and utilities in establishing and maintaining greenhouse gas emission reduction projects. Like NRG Energy, the company focuses on managing the entire process from project inception to final delivery. CSI is as independent as NRG Energy as it has its own standard solar module and a special solar module. Furthermore, just like NRG Energy, it is a product company capable of managing consumers of its products located in various markets around the world. Headquartered in Longyan, a Fujian province of China, China Biodiesel's main focus is the commercial production of biodiesel. Maintaining its innovative edge just like NRG Energy, China Biodiesel has developed proprietary processes and technologies, using cooking waste and other oils, to produce biodiesel (Bert 2007). China Sun Biochem recently completed construction of an ethanol plant in Shenyang, China, giving the company a comparative advantage over NRG Energy.
