APEx was formed to promote the common business interests of parties engaged in the electricity and gas transmission and trading industry. One of its primary intentions is to provide a platform for sharing information between its members. APEx performs these functions by holding an annual conference of its members, as well as periodic, online webinar sessions featuring topics of interest in the ongoing development and operation of electricity and natural gas markets. The annual conference is held in a different part of the world each year, and attended by around 100 executive-level delegates from APEx members, regulators, government dignitaries, consultants, and vendors.
These conferences represent significant opportunities for energy market executives to learn from each other about challenges facing the energy industry around the world, as well as best practices for addressing these challenges both in the present and in the future.
APEx was formed and held its first annual conference in 1996 in Melbourne, Australia. Since then, APEx has held 25 such annual conferences, one every year with the exception of 2020 and 2021 when in-person attendance was not possible due to the COVID-19 pandemic. During those two years, APEx held online webinars open to its membership as well as other attendees in order to maintain the regular flow of information and ideas between and among its members. APEx has since held six webinar events, and has added online attendance as an option for its annual conferences as well. Since its formation, APEx has grown to over 45 members representing energy exchanges all over the world, and in various stages of development and maturity.
