2005-6 46 3. Trial Operation and the Development of the Northeast Regional Power Market

z Development of transient single-part tariff market

z Development of two-part electricity tariffs

z Trial operation

2005-6 47 Market Development of Transient Single-Part Tariff

z In February 2003, the State Electricity Regulatory Commission (SERC) decided to experiment with electricity market in the North East Company z On 6 June 2003, SERC issued the “Instruction on Establishing Northeast China Regional Power Market”(No. 2003 15) z The North East Power Grid Company Ltd. was officially established on 25 September, and the Northeast Power Dispatching and Trading Center was set up under it. z On 31 December 2003, a series of publications and regulations on this subject were issued , including the Single-Part Transient Tariff Executive Program z On 15 January 2004, the single tariff simulation operation was started, and 5 monthly simulation sanctions were concluded

2005-6 48 Market Development of Two-part Tariff

z On February 2004, the Northeast Electricity Regulatory Bureau preparatory group was found. z On April 27th 2004, the NDRC issued the Notice of Generation Tariff Reform Pilots in Northeast Regional Power Market(No 2004. 709). z From May 10th to 11th in 2005, a meeting was held in to seek comments from relevant parties on regulations and methods on the northeast regional power market z From 17th to 18th in May 2004,the meeting to seek comments from grip companies and generation corporations was held in Beijing. z On May 24th 2004, the executive plan and regulations on two- part tariff came out.

2005-6 49 Market Development of Two-part Tariff—cont’d

z On 19 June 2004, the simulation operation on two-part generation tariff was started. z From 13 to 22 December 2004, the annual contract bidding for 2005 was consummated. z However, the monthly bidding from January to April 2005 was deferred because of the difficulties in coordinating generation companies after the yearly bidding. z In April, the SERE and NDRC jointly issued the Notice of Starting Trial Operation on Monthly Bidding in the Northeast China Power Market (No. 6 , 2005). z From April 22 to 25, the monthly contract trading for May was concluded. z From May 22 to 25, the monthly contract trading for June was concluded

2005-6 50 Trial Operation

Yearly Trading

z The annual trading quota was 86.278 bil kWh, with a quota of 43.139 bil kWh for each time. It concluded in 2 phases.

z The weighted average tariff of the tender electricity of the two yearly sanctions was 191.029/kWh. Accordingly, 0.2 billion surplus of balance funds is expected.

2005-6 51 Trial Operation

Monthly Trading

z The quota of bidding in May was RMB 1.884 billion and the average tender tariff was 270.092 yuan/1000 kwh. Therefore, the deficit of balance funds is expected to be 78.46 million.

z The quota of bidding in June was 1.728 billion and the average tender tariff was 267.388 yuan/1000 kwh. A deficit of 47.62million is expected.

2005-6 52 Trial Operation

Features

z Generation companies were serious, active, and rational for market offering z Reasonable tender results reflected market laws z The allocation of resources was optimized within the Northeast region z With accurate and serious safety check, the trading results were able to ensure the network to operate safely z Technical support system operated steadily and trading calculation went right z Rules are specific and clear, and show no apparent weakness

2005-6 53 4. Lessons and Future Work

z Lessons

z Future Work

2005-6 54 Lessons

z To evaluate the trial operation, establish and revise rules to make it perfect, then, turn to formal operation at appropriate time

z Further study “Next day” Trading and implement it at the right time

z Resolve the problem of North China electricity to have access to market

z Increase market players and extend the scale of large consumers for direct provision of electricity

z Study auxiliary service market and introduce it at the right time 2005-6 56 Thank You!
