Renewable and Low-Carbon Electric Power and Grid Integration

Led by Michael McELROY (Chair, Harvard-China Project), LU Xi (Tsinghua School of Environment and Project alumnus), and postdoctoral fellow CHEN Xinyu, Project researchers have explored the status and prospects for renewable and low carbon electric power in China including the challenges of, and potential solutions to, integration of variable renewable sources into an inflexible, coal-based electricity grid.

From assessing wind power potentials using meteorological data and the geophysical constraints, to exploring diverse energy storage and other strategies to ease grid integration of variable power sources, this research has deepened understanding of the role renewable energy can play in reducing emissions of air pollutants and carbon dioxide in China.

The assessment of the economic potential of wind electricity is of critical importance for wind power development in China. Based on the wind resource data between 1995 and 2014 and geological assumptions, this paper calculates economic potential of China’s onshore wind electricity. Furthermore, it builds an econometric model to update the net-present-value model, based on a survey sample of various wind farms. Results show that the economic potential of China’s onshore wind electricity is 8.13 PWh per year with a feed-in-tariff price at 0.60 yuan (about 9.6 U.S. cents) per kilowatt-hour.

The United States has committed to reduce its greenhouse gas emissions by 26%–28% by 2025 and by 83% by 2050 relative to 2005. Meeting these objectives will require major investments in renewable energy options, particularly wind and solar. These investments are promoted at the federal level by a variety of tax credits, and at the state level by requirements for utilities to include specific fractions of renewable energy in their portfolios (Renewable Portfolio Standards) and by opportunities for rooftop PV systems to transfer excess power to utilities through net metering, allowing meters to operate in reverse. The paper discusses the current status of these incentives.
