Electricity portfolio innovation for energy security: the case of carbon constrained China

China’s energy sector is under pressure to achieve secure and affordable supply and a clear decarbonisation path. We examine the longitudinal trajectory of the Chinese electricity supply security and model the near future supply security based on the 12th 5 year plan. Our deterministic approach combines Shannon-Wiener, Herfindahl-Hirschman and electricity import dependence indices for supply security appraisal. We find that electricity portfolio innovation allows China to provide secure energy supply despite increasing import dependence. It is argued that long-term aggressive deployment of renewable energy will unblock China’s coal-biased technological lock-in and increase supply security in all fronts. However, reduced supply diversity in China during the 1990s will not recover until after 2020s due to the long-term coal lock-in that can threaten to hold China’s back from realising its full potential

Mexico should schedule, throughout the life of this Minute, no more than the minimum Treaty requirement of 900 cfs during the months of October, November, December, January and the first 12 days of February, for a total of 135 days during each calendar year. 6. Mexico should furnish, as far in advance as practicable, (a) its schedule of Treaty deliveries in each calendar year with as much detail as possible, and (b) any amendments which may be necessary from time to time. It should limit the changes in schedule from day to day to a maximum of 300 cfs, except on March 1 and October 1, when the maximum change may amount to 600 cfs. 7.

Proposed Minute of the International Boundary & Water Commission, Draft

Document: "Proposed Minute of the International Boundary and Water Commission, United States and Mexico to Achieve a Permanent & Effective Solution to the Colorado River Salinity Problem," 1964 (photocopy), page 22. The control structure proposed in Recommendation I should be operated to permit the discharge of all of the District's drainage water below Morelos Dam, except that at Mexico's request these waters would be discharged above the Dam at such times and at such rates as Mexico may specify in its water schedule. All drainage waters, whether discharged above or below Morelos Dam, should be accounted for by the Commission: a. During the period Oct 1-February 12, without distinction between guaranteed scheduled deliveries and other water reaching the limitrophe section. b. During all other times as in satisfaction of Mexico's scheduled deliveries. 3. The pumping of drainage waters from the District which are to be delivered to Mexico above Morelos Dam should, in so far as practicable, be coordinated with Mexico's diversions to the Alamo Canal, i. e., the more saline wells should be pumped during periods when the scheduled diversions are high and the less saline wells should be pumped when the scheduled diversions are low. 4. The United States should discontinue, in so far as practicable, discharges from the waste ways of the Yuma County Water Users' Association to the boundary section of the Colorado River below Morelos Dam and, if practicable, construct works to effect such discharges as a part of the deliveries near San Luis, Arizona, at the expense of the United States. Mexico should pay the increased cost of pumping, which may be required to discharge these additional Yuma Valley waters to Mexico at the delivery point near San Luis, Arizona. 2.Epson Perfection 4870 Photo, 400 dpi, 8 bit, 1,769,662 byte
