8. Why the time of data has been divided into blocks of 15 minutes? Is it an International standard of specific to our country?
In Indian Power Market, the settlement system is for 15 minute block, i.e. scheduling, recording of actual generation/consumption, computation of deviation etc., is done for each of the 96 (15 minute time block) blocks of the day. Energy Meters are installed and the energy exchange data is recorded for each of the 15 minute time block, starting from 00:00 hrs. of the day. Accordingly, the data is displayed for current 15 minute time block.
While most of the countries adopted hourly settlement system, India is one of the first to adopt sub-hourly settlement system. Thus, the 15 minute period is specific to Indian context.
9. What does “Demand Met” indicates. Does it mean that the present demand in India or State?
Demand Met figure indicates the demand being met currently. The current Demand met figure is regularly updated from the information collected at NLDC/RLDCs.
The daily / weekly / monthly power supply position reports are available at concerned RLDCs and NLDC websites.http://nldc.in/ or http://posoco.in/
Further, Total Installed Capacity, Daily / Monthly Generation reports etc. are available at Central Electricity Authority website http://cea.nic.in/
10. Does surplus power shown for exchange indicate that this power is available in India through exchange and no consumer/utility is there to purchase the same?
In case of Power Exchange, both buyer and seller submit their bids for each of the 96 time blocks. In buy bid, buyer specifies the quantum of power (MW) and price at which it wants to purchase power. Similarly, each seller submits its bid and specify the quantum of power (MW) and price at which it wants to sell power. The power exchange than match sell bids and buy bids and calculates market clearing volume.
The difference between the Sell bid quantum and market clearing volume for that particular time block is shown as surplus power available at power exchange. If total quantum of buy bid offers is less than the total quantum of sell bid offers then it will indicate surplus power available at power exchange. It means supply is more than the total demand in that time block.
For further detailed information e.g.; total buy or purchase bid, sell bid, Market Clearing Volume (MCV), Cleared volume, Market Clearing Price (MCP) etc. one can visit the market snapshot on the power exchanges websites:http://www.iexindia.com/marketdata/market_snapshot.aspx
11. Is average market clearing price is for a day or for that particular time block? Is it simple average or weight average?
Average market clearing price is for the day. After obtaining the buy and sell bid, Power exchange run their application to obtain the unconstrained market clearing price (UMCP) and unconstrained market is clearing volume (UMCV) for each of the 96 time blocks in a day. The simple average of these UMCP is the average market clearing price for a day.
For further detailed information e.g.; total buy or purchase bid, sell bid, Markect Clearing Volume (MCV), Cleared volume, Market Clearing Price (MCP) etc. one can visit the market snapshot on the power exchange website.
The second page of the market snapshot on the power exchange website provides information in a summarised form e.g.; maximum, minimum, average value of the 96 time blocks in a day.
12. Why have states been grouped together? What is the basis for the same? Why is the power price same for all states in a group?
Indian Grid is demarcated in five regional grid (namely Northern Region, Western Region, Eastern Region, Southern Region and North-Eastern Region) depending upon the geographical location and political boundaries. All the States within that region are grouped together. Normally there is no transmission constraint for power exchange within the Region, therefore the prices are same for all States in a Group. However, in some regions, there may be transmission constraints for power exchange within the region itself, say in Southern Region. In Southern Region States Andhra Pradesh, Telangana and Karnataka are grouped together and called bid area S1 and Kerala and Tamil nadu are grouped together and called bid area S2. So within one bid area there is no transmission constraint and prices are same within that bid area. At present based on experience 12 bid areas have been defined. However, these bid areas can be increased depending upon the congestion experienced. For getting details of bid areas presently being defined, one can visit the power exchange website at following link:http://www.iexindia.com/bidareas.aspx?id=31&mid=2
13. Why, for some blocks, power price is different for a different group of states? Is there is the possibility of single price all over India? Does single price is good or bad for the country?
In case there is a transmission constraint for exchange of power from one bid area to another bid area then market splitting takes place. The prices in bid area where more generation is available at lower cost (upstream) reduces as it is not possible to despatch all generation and accordingly the prices in the bid area where there is more demand increases.
In case there is no transmission constraint, then the prices in all the regions/bid areas will be same. At many occasions single price for all over India has been obtained.
Single price is good for the country as it reflects there is no congestion in the National Grid and power from the seller who wants to supply at lowest cost is despatched to the buyer who is valuing most for that power during that time. Single price for the entire country will result in social welfare maximisation.
For getting details on area prices and cleared area volumes one can visit the power exchanges websites:http://www.iexindia.com/marketdata/areaprice.aspx and
14. As per details on the app, the power price data is from power exchange. Does this represent the price of all the power flowing on the grid in the current block? If no, for how much percentage of power these prices apply?
The price shown is the area prices obtained at Power exchange in the day ahead market. This does not represent the price of all the power flowing in the grid in the current time block. Presently only 3 to 4 % of total demand is traded through power exchange.
For further information regarding short term transactions of electricity in India, monthly and annual reports can be obtained from CERC websitehttp://cercind.gov.in/market_monitoring.html
15. If power is available at much lower rate than domestic/Industrial consumer tariff then why domestic/industrial tariff is much higher ?
The State DISCOMs manages its portfolio through a number of products e.g. allocation from ISGS, Long term agreement, Medium term open access, bilateral agreements, allocation from State generation etc. The price here shows the power procurement in the day ahead market at regional periphery. Therefore, the average cost of power procured by States may be different than the price shown here. Further, the end consumer tariff also includes the transmission charges, distribution charges, State transmission and distribution losses etc. Therefore the end consumer tariff is higher than the prices in day ahead market. The information disseminated through the Application will empower the consumer, thereby leading all the stakeholders to be more responsive and efficient, bringing more economy to the country.
16. On one hand it shows surplus power available and also it shows shortages in some States. What is the reason for such shortages?
The shortage figure for the State is as per the information provided by the respective State. Only the respective State can state the reason for such shortage. It may be due to network constraint in the State transmission or distribution network, availability of funds, empowerment for procurement of power, etc.
17. What is the source of data?
Each State provides information of shortage if any, etc. The information from all States are compiled at National Load Despatch Centre through respective Regional Load Despatch Centres and power exchanges provides information related to market related data e.g. market price etc. Data from multiple sources, including the States and Power Exchanges, has been made available through a single portal for convenience of all.
18. In my State, as per the information available through this application there is no shortage of power. However, we don’t have power supply for hours together. What could be the reason for same?
The shortage figures for the State are as per the information received from the respective States. Only the respective State can state the reason for the same. It may be due to network constraint in the State transmission or distribution network, obligation to supply to a particular group of consumers etc.
19. How shortages data are being captured?
