一、 General ideas of NG Development

NG consumption increased 0.3~0.35 BM3 annually from 1997 when

the NG was first introduced into Beijing.

Residential consumers annual increase was 0.25~0.3 Million.

Heating boilers including coal shift to gas boilers and new

consumers increased 1000~5000t/h per year, which was the main

contribution of Beijing’s environmental improvement.

Beijing NG consumption was 0.18 BM3 in 1997 with 200 thousand

residential consumers and no heating consumers.

NG consumption was 2.2、2.54 BM3 in 2003 and 2004. Heating use

was near to 1.2、1.5 BM3 and heating floor areas was about

0.1、0.14 BM2 which accounted for 30%、35% of total floor

areas.

Data in 2003Total consumers were 4.613 million

Beijing gas group supplied 2.43 million NG consumers、111 thousand coke gas consumers and 1.233 million LPG consumers.

Other 839 ths. consumers was supplied by small gas companies.

Total pipelines were about 6346 kilometers

Supper high pressure pipes were 184 kilometers

High pressure pipes was 343 kilometers.Medium pressure pipes was 1944 kilometers.Low pressure pipes was 3875 kilometers

There were 587 NG pressure reducing stations

12 Supper high pressure stations, 37 High pressure stations, and 473 medium pressure stations

There were 3157 pressure regulators(medium to low)

4 Storage tank stations. Total capacity 700000 M3

NG PriceNG price was regulated by Beijing and central government, mainly according to the investment and operation costsThe average price in 2000 was about 1.5~1.6RMB/cubm

Cooking 1.4RMB/cubmspace heating: 1.8RMB/cubmIndustrial: 1.8RMB/cubmCommercial buildings: 2.4RMB/cubm

Gate station price was 1.1RMB/cubm in 2000, including mines and pipeline cost, which was made by central government

NG Price

Since the large scale of city NG pipelines construction and heavy management cost, Beijing government had to subsidized the deficit of Beijing Gas Supply Group before the year 2003.The NG price was 1.8 RMB/cubm in 2003

Cooking 1.8 RMB/cubm Space heating 1.8 8RMB/cubm Commercial buildings 2.4~3.0 8RMB/cubm

二、Medium/long term NG demand forecast

Beijing city master plan of 2020Total population is 18 million

Total floor areas is 0.8~0.9 BM3

City spatial structure is “two axes, two zones,

multiple centers”Two axes are Chang’an Avenue and north-south center axis

Two zones are eastern development zone and western

ecological zone

Multiple centers are main city、two side

centers(Shijingshan and Tongzhou)、9 new center towns

Energy mixClean energy will account for more than 80% in energy mix in 2010Clean energy will account for more than 90% in energy mix in 2020NG will account for 12% in final energy consumption in 2020

二、Medium/long term NG demand forecast

2005-4-8 16

NG demand in 2010 is 6-7 BM3Residential demand (mainly cooking and domestic hot water) is 1.3 BM3Space heating demand is 2.5-3 BM3. Warming About 0.25 BM2 floor areas Electricity generation demand is 1.5-2 BM3Air-conditioning、industrial and vehicles demands are 0.7 BM3

二、Medium/long term NG demand forecast

2005-4-8 17

NG demand in 2020 is 10.8-11.8 BM3Residential demand (mainly cooking and domestic hot water) is 2-2.4 BM3Space heating demand is 4.2 BM3. Heating About 0.41 BM2 floor areas, including 60% of urban floor areas and some of the new center city floor areasElectricity generation demand is 3.2-3.8 BM3Air-conditioning、industrial and vehicles demands are 1.7 BM3

NG demand versus the present consumption of other countries

In the year 2020-2030, Beijing NG demand is lower than the present average consumption of developed countries, a little bit higher than the present consumption of Japan and Korea

三、NG resourcesFor the safety of mega city NG supply, NG supply system requires the NG resources secure and abundant. NG supply safety requires multiple resources from multiple directionsNG supply and network facility must not only fulfill the normal demand, but also keep the supply in the emergency and have some strategic storage.According to the NG resources available in China and in neighborhood regions, Beijing will introduce at least 3 NG sources, Shan’an’ning，Siberia, and LNG from Asia-Pacific regions.At same time, large underground gas storage field should also be in construction, so that the NG can satisfy the the big peak load for heating
