3 English summary Energy demand in China is growing to keep pace with rapid economic and social development. In 2020, it is expected to reach 4.5 to 5 billion tonnes of coal equivalent (tce) per annum, rising to 6.5 billion tce per annum in Electricity demand growth is likely to rise even more steeply, reaching TWh in 2020, TWh in 2030, and TWh in 2050, up from TWh in The Chinese government has proposed a lowcarbon development strategy, in which wind power will play a central role. Some 15 GW of wind power capacity will be installed each year up to Cumulative operational capacity in that year will be 200 GW, up from 31 GW at the end of 2010, meeting 5% of electricity production (400 TWh), up from 1.3% today. Between 2020 and 2030, some 20 GW of wind capacity will be installed every year, to reach 400 GW in 2030, equivalent to 15% of all installed power capacity, covering 8.4% of electricity production (840 TWh). From then up to 2050, this roadmap sees deployment on land and offshore of 30 GW per annum, around half of annually installed power capacity, amounting to GW in 2050, 26% of all installed capacity, meeting 17% of total electricity production (2 200 TWh) (Figure 1). While these are ambitious targets, this roadmap finds that none of the challenges it has identified is insurmountable. The GW in 2050 are expected to be divided among seven areas: Western and Eastern Mongolia, Gansu, Xiangjiang, Jilin, Heibei and Jiangsu. Jiangsu province will also see deployment offshore in intertidal, shallow and deep waters. Investment costs on land are expected to range from RMB 7 200/kW to RMB 7 500/kW in 2020, falling to RMB 7 000/kW in Near shore costs of RMB /kW are anticipated in 2020, falling to RMB /kW in Deep offshore costs are expected to be RMB /kW in 2020, falling to RMB /kW in Cumulative investment in wind capacity over the roadmap period will have amounted to some RMB 3.8 trillion (USD 600 billion) in 2030, and RMB 12.1 trillion (USD 1.9 trillion) in 2050 (Figure 2). This roadmap visualises a maximum tariff for wind energy of RMB 0.55 / kwh. This is based on regional capacity factors, investment cost and includes an assumed reasonable return on investment. Ensuring that costs do not rise above these levels has been a primary driver behind selection of the seven primary deployment areas. The lowest average production cost areas are Inner Mongolia and Hebei province.

4 It is expected that the production cost of landbased wind power will have fallen to a level roughly equal to coal by 2020, after which time it is expected to be cheaper. If external environmental costs are included as well as transmission costs, it is still expected to be cheaper. Consequently, from this point in time wind power incentives should be directed solely towards offshore wind, which in 2020 will be seeing large-scale deployment. Meeting the targets identified in this roadmap will result in great environmental and social benefit. Avoided coal consumption will amount to 130 million tce in 2020, 260 million tce in 2030, and 660 million tce in This will reduce annual CO 2 equivalent emissions by 0.3 gigatonnes (gt) in 2020, 0.6 gt in 2030 and 1.5 gt in In the same years, sulphur dioxide emissions will have reduced by 1.1 megatonnes (mt), 2.2 mt and 5.6 mt respectively. The negative environmental impacts of wind power are expected to be negligible. Employment in 2020 resulting from wind power is expected to be around 1.5 jobs per megawatt. With efficiencies and economies of scale this is expected to fall to some 1.1 jobs/mw in 2020 and 0.8 jobs/mw in This roadmap expects the wind industry to employ some individuals in 2020, rising to in 2030 and nearly three quarters of a million in There is still significant room for advances in technology over the next four decades. RD&D activities will focus on deeper understanding of wind resources, improved wind turbine performance, wind farm optimisation, reduced operation and maintenance burden, and larger turbines. From 2020, turbines in the 5 to 10 MW scale are expected to be commercially available, particularly for deployment offshore. Increased requirement for raw materials will be a major feature of scaling up wind power. The supply of steel for turbine towers is not expected to be constrained, nor the permanent magnet material, neodymium, for use in direct drive generators. In contrast, the production of carbon fibre for rotor blades is already well behind developing economies: domestic production will need to increase sharply to provide for the expected need for tonnes in Chinese industry expects to have fully addressed technical aspects of intertidal wind farms by 2015, and shallow offshore technology by 2020, Figure 2: Cumulative wind power investment in China, Accumulated investment (RMB billion) Source: ERI 2 China Wind Energy Development Roadmap 2050

5 after which deep offshore demonstration will commence (R&D in this area will commence before 2015). China s offshore programme will require the transformation of existing ports and the development of new facilities, possibly located on islands to reduce weather related deployment uncertainties, as well as the development of specialised installation and transport vessels after Wind power deployment can not be seen in isolation. Such large capacities of wind power will inevitably have influence on the wider power system. Up to 2020, R&D will focus on advanced, centralised forecasting techniques ranging from 72 hours ahead up to three ahead of the time of delivery. Grid friendly wind farms are anticipated by 2020, featuring active and reactive power control, fault ride through and frequency regulation capabilities. By 2030, with the deployment of system storage, grid reinforcement and advanced scheduling and dispatching techniques, inter alia, wind power across the country is expected to provide similar system support to conventional power plants. Up to 2020 and beyond, the majority of wind power deployed will be in the north of China, far from load centres. Therefore efforts are needed to maximise the consumption of wind power locally, and minimise curtailment. Deployment of wind power plants must be co-ordinated with that of other plants types, particularly those which are technically more flexible, and transmission roll-out plans across the seven target regions. Two pathways for development of the transmission system have been identified, one which retains the existing six regional power grids, strengthening integration among them, and one which sees the development of a new ultra-high voltage AC grid covering the main load centres in the centre and east, with DC connections to the north east, northwest and south. Power sector reform will have enormous influence on the deployment of wind power. China is already making transition to more advanced power plant dispatch practices wherein cost and CO 2 emissions of different plant types are taken into account. Wind power has first priority in dispatch, but in order for this to be the case in practice a more transparent power market is needed, and planned for Efforts are needed to increase the transparency of power prices, and to integrate the external environmental costs of polluting types. Power prices should reflect the value of flexibility of power plants. In the mid-term, environmental and carbon tax approaches should be evaluated for use in China. Unbundling vertically integrated players is an important task. Facilitating trade among provinces will help accommodate large fluctuations in wind output. In concert with advanced forecasting techniques, centralised operation of wind power plants will help smooth their aggregated output. More of existing flexible resources must be made available through new ancillary service markets and smart grid technology for balancing fluctuations in output. Consumer response will be activated to some extent by new peak-andvalley pricing. And greater flexibility should be developed in the conventional generator fleet, including new hydropower deployment in the west, gas fired power plants for peaking and improved ramping capability of conventional thermal plants. Key actions to 2020 zreform power market to achieve marketbased power pricing, reflecting environmental externalities, the value of flexibility and integration costs. zstrengthen priority grid access and dispatch of wind power; maximise the ability of northern provinces to accommodate locally produced wind power; facilitate interprovincial transmission using smartest available technology. zaccelerate deployment of flexible resources; deploy best available output forecasting techniques; activate consumer response to electricity scarcity. zestablish a renewable R&D fund and common experimental platforms. Develop and deploy cost competitive 5 MW technology by 2015, and near offshore technology by zstrengthen supply chains, especially offshore transport and installation infrastructure, and carbon fibre availability. z Develop specialist wind power training courses and university curricula by Summary 3
