The missing e-car charging stations in Beijing

See my earlier post on the meeting with Beijing’s vice mayor, where my report on the planned amount of new charging stations for 2014 was confirmed: 1,000 stations for e-cars.
Now Caixin just reported that State Grid had planned to build 197 charging stations this year with a total investment of 3.88 billion yuan. As far as I know, no mention of other companies involved. So, who will build the remaining 800 charging stations?
