As a matter of government policy and corporate strategy, China has been intensifying its effort to set indigenous standards for homegrown ultra-high voltage (UHV) transmission technology. The country also aims to contribute to UHV standards internationally. Indeed, this process of standard setting, influenced by both economics and politics, will have ramifications far beyond China’s borders. The potential internationalization of China’s domestic UHV standards will almost certainly affect the global market share for both Chinese manufacturers and dominant multinational companies.This paper explores China’s UHV standardization process and the myriad challenges it faces, from a technical, economic, and political standpoint. But beyond simply detailing China’s strategy in pushing out its own UHV technology to the domestic and international markets, the paper discusses how China’s ambition for its indigenous technology could ultimately pose a considerable challenge to global competitors who hope to sell comparable products. The paper concludes by outlining several potential scenarios for how China’s UHV standardization process, and its relationship to global standard setting, may ultimately evolve.
