THE
POOL
The Electricity Pool operated from 1st April 1990 to 26th March 2001 and dictated the way in which electricity was distributed around England and Wales. Unlike NETA (from 27th Match 2001), the Pool involved bids from only the Generators who set the price of wholesale electricity via the System Marginal Price.

New
Electricity Trading Arrangements – NETA/ BETTA.
The New Electricity Trading Arrangements came into force on 27th March 2001 and involve both the Generators and the Suppliers trading in the wholesale electricity market. The arrangements favour those generators which can accurately predict the likely generation and/or supply, and also have the ability to respond to sudden changes (by increasing or reducing generation and increasing or reducing demand).
On 1st April 2005, NETA was extended to cover Scotland and is now known as BETTA.
