Amerex Brokers LLC

Amerex Energy Services was created in 2004 to complement the efforts of Amerex Brokers, LLC, which was founded in 1978. Amerex Brokers is a leading over-the-counter (“OTC”) energy brokerage offering services in electricity, natural gas, emission credits and allowances, renewable energy credits, retail energy procurement, energy consulting and energy data services.

Amerex Brokers LLC is a wholly-owned subsidiary of GFI Group Inc. (NYSE: GFIG), a leading inter-dealer broker specializing in over-the-counter derivatives products and related securities.


As one of the oldest and largest over-the-counter energy brokers in the world, Amerex offers comprehensive daily indicative price reports covering the North American gas, power, and environmental markets. Amerex also offers a historical database with over 13 years of historical data. Amerex operates deep and liquid physical and financial electrical power and natural gas markets at all the major market hubs throughout the U.S. and Canada. Amerex has been an innovative pioneer in the North American electrical power markets since 1994. Amerex natural gas markets offer a broad variety of traded instruments that include basis, fixed price, index and swing swaps; physical and financial options; EFP’s and both long and short term forwards. Amerex has been an innovative pioneer in the North American natural gas markets since 1990.

As of November 2013, Amerex brokered an average of 6 million megawatt hours of electrical power and 140 billion cubic feet of natural gas each business day.

Amerex began brokering emission allowances in 2001 with a focus on U.S. Federal SO2 and NOx forwards and options. In 2002 we expanded our service offerings to include multiple regional markets such as HGB NOx. Since that time the traded emissions markets have continued to expand as more and more states are required to implement pollution reduction plans as part of the Federal program. Today, Amerex brokers all the U.S. Federal and regional emissions markets including NOx, SO2, HGB NOx, ERCs, DERCs and RECs. Amerex offers both long and short term forwards as well as options in each of these products and is an industry leader in structured emissions transactions.
