JEPX provides the following two types of market and bulletin board:

 

<Spot Market>

 

The market where the electricity to be delivered next day is traded. 48 products are traded every 30 minutes in 24 hours a day. 

The bidding is done by a single price auction system. Under the single price auction system, a bid is made for the

combination of price and quantity of each product. A point of intersection where the buying and selling

conditions comply with each other is sought, and the price and contract quantity are decided at this point.

 

<Forward Market (Fixed-Form Products)>

               

The market where the electricity to be delivered in a certain period of time is traded. 

As of 2005, there are 24-hour type products that are delivered at anytime a month and

daytime products that are delivered during a certain time period a month. 

The bidding is done by the so-called continuous session system.

 

<Forward Market (Bulletin Board Products)>

               

In the forward market for bulletin board products, participants freely post matters related to electricity trading.
