the model master power purchase and sale agreement is an attempt to standardise the core terms and conditions needed to establish trading relationships in the US power markets by providing standard documentation for all trading agreements. The master agreement was developed by Washington, DC-based Edison Electric Institute (EEI), an association of US electricity companies, and implemented in spring 2000. In Europe, common master agreement templates include the International Swaps and Derivatives Association (ISDA), the European Federation of Energy Traders (EFET) and the UK’s Grid Trade Master Agreement (GMTA).
