About Energy Link

The electricity industry continues to evolve rapidly and is undergoing unprecedented change as the high cost of energy and its impact on the climate have created their own climate in which technology is driving change down to the lowest levels - your home. 

Our Story

When the New Zealand electricity industry deregulated in 1996, Greg Sise saw an opportunity to assist smaller players to compete in the newly formed wholesale electricity spot market. He founded Energy Link, and almost three decades on, we have the people, insights, and specialised in-house and online software systems to support our clients through all stages of development and execution of their energy strategies.

Our reputation for providing high quality service and expertise is unequalled in the industry. We are sought out by New Zealand’s blue-chip companies and by government to help with the “big, tough” energy decisions. As a client once said, we “eat, sleep and breathe” electricity. 

About Us

We are leaders in the fields of procurement, risk management, hedging for electricity, software and in systems for managing energy. We are not an energy trader - we do not sell you energy, hedges, or other financial instruments.

We are non-aligned and provide independent services to electricity and natural gas market participants, larger energy users, lines companies, independent retailers and generators, local government, government agencies and the investment community.

Our three indices for fixed price electricity contracts –CFD, FPVV and mixed CFD/FPVV - are published monthly in our free Energy Trendz publication HERE. The indices are widely used for assessing electricity contracts and are referred to in publications produced by the Electricity Authority.
