4 What is Strog & Smart Grid? Strog & Smart Grid is based o a strog grid etwork, supported by a iformatio-commuicatio platform, with smart cotrollers coverig aspects from geeratio, trasmissio, distributio, customer service to dispatchig. Strog & Smart Grid is the carrier of power flow, iformatio flow ad work flow. It is a strog, reliable, ecoomical, efficiet, clea, trasparet, ad iteractive itegratio. 4

5 Characteristics of Strog & Smart Grid Strog ad Smart is the base of Strog & Smart Grid Oly with a strog etwork as the foudatio, plus Iformatioizatio, automatio, iteractio as techical highlights, ca we brig Strog & Smart Grid fuctios to full play Iformatioizatio Itese itegratio ad exchage of real-time iformatio Automatio automatic selectio of cotrol strategy self-healig i case of damages ad cotigecies Iteractio Iteractio amog power geeratio, power grids, ad ed customers 5

9 Mismatch of Power Geeratio ad Cosumptio 2/3 of coal resources, wid power, solar power is located i North ad Northwest. Northeast North 4/5 of the hydropower resources is located i Southwest. Tibet Northwest Cetral East Over 2/3 of the power demad cocetrates i E ast ad Cetral Chia South Tras-regioal ad provicial power exchage volume i 2009 reached 404TWh. There is large scope for electric power growth due to rapid growth of Chia's ecoomy. The total istalled capacity for electricity is expected to icrease from 870GW i 2009 to 1,700GW i

10 Rapid Developmet of Clea Eergy i Chia Reewable geeratio is boomig u The growth rate of Chia's istalled wid Power is much higher tha the world average level Ø Istalled wid power ü I 2005 : 1, 260 MW ü I 2008: 12, 210 MW. Ø I 2008, Chia's ewly istalled wid power reached 6,300MW, accoutig for 22% of the world's total icremetal capacity u Large-scale utilizatio ad Itesive exploitatio of reewables geeratio Ø Seve 10-GW level wid farms will be built i west ad orth part of Chia. Wid geeratio ad solar PV geeratio will pose a greater challege to power grid's security ad stability due to their radomicity, itermittece ad volatility. Uit 10 MW

11 Build Strog & Smart Grid It is a historic choice for Chia to speed up the buildig of a strog & smart atioal grid with the ultra-high-voltage grid as the backoe ad subordiate grids operated i coordiatio, ad to upgrade from covetioal grids to moder grids
