Total solar PV electricity production forecast in China 2017-2050

* Scenario was forecasted base on a below two degree Celsius scenario with the following boundaries and assumptions:

Scenario boundaries
The boundaries for the long‐term energy and economic development are constraints to the deployment of various energy technologies:
 Renewable energy resources are constrained at provincial level, and wind and solar are divided into categories of costs, type and quality.
 Hydro power plants are limited to deployment of 532 GW, based on existing capacity and environmentally sustainable build out opportunities.
 Nuclear capacity is limited to 120 GW along coastal regions.
 CCS is not taken into account as a technology option, since no clear data on technology costs and performance is available.


scenario assumptions
The scenarios are based on the following main assumptions:
 Both scenarios assume full and vigorous implementation of the current and stated policies for the energy sector as expressed in the 13th Five‐Year Plan and the 19th Party Congress. This includes a power market reform and a national CO2 emission trading scheme.
 Economic development objectives must increase GDP by a factor of 4 in real terms, from RMB 82 trillion in 2017 to RMB 324 trillion by 2050.
 Both scenarios actively support the new economic development by creating markets for strategic emerging industries like electric vehicles, data centers and IT services with high consumption of electricity and clean energy technologies.  Population is expected to be on today’s level at 1.38 billion in 2050.
 The short‐term goals in the 13th Five‐Year Plan on energy will be fulfilled in 2020, as well as the targets in the Three‐Year Action Blue Sky Protection Plan, the 13th FYP for Environment Protection and the North China Clean heating plan.  Energy efficiency vigorously reduces final energy consumption, e.g. in the Below 2 °C scenario is thereby 56% of a no improvement situation by 2050 and slightly higher in the Stated Policies scenario.
 Strong electrification of the final energy consumption, aiming at around 60% electricity in the end‐use sectors.
 Focus on security of supply including strong efforts in reducing dependency of imported oil and natural gas.
 China achieves the goal of 10% of natural gas in total primary energy consumption by 2020 and in the Stated Policies scenario, natural gas consumption will increase to 15%. The Below 2 °C scenario does not require the share to increase after 2020.
 The 50% non‐fossil electricity generation target of the Energy Consumption Revolution strategy is attained, and in practice exceeded in the scenarios.
 The Stated Policies scenario has the carbon intensity reduction target of 40‐45% by 2020 and 60‐65% by 2030, though this is not binding. CO2 prices in the in the power sector rise linearly from RMB 50/tonne in 2020 to RMB 100/tonne in 2040.
 The Below 2°C scenario, the accumulated energy sector emissions from 2017‐2050 is kept below 230 billion tons. This is based on several different simulations from the IPCC AR5 database with a greater than 66% chance of staying Below 2°C.
 Technology costs are assumed to have declining installation and operational costs per MW as well as quality improvements of RE technologies. Grid parity is achieved for most wind and solar installations in the 2020s on LCOE basis, and most mainstream RE is significantly less costly than fossil generation by 2050.  Coal and natural gas prices follow the indexed development of the IEA World Energy Outlook 2017 New Policies scenario in the Stated Policies scenario, and the IEA’s Sustainable Development scenario in the Below 2 °C.
 Coal is constrained to 1 billion tons by 2050
