Energy & Renewables

With the drive towards decarbonisation and emission reduction, the energy sector is undergoing a rapid and comprehensive transition.

Traditional players are adapting their business models and new local and international entrants are investing heavily, particularly in renewables.

Simpson Grierson has long been regarded as a key legal adviser to the New Zealand energy sector, and we are at the forefront of helping clients navigate the changing landscape. We are heavily involved in the growth of New Zealand’s renewable energy sector, advising on a number of new solar, geothermal and wind generation projects.

We assist clients to develop projects, from financing, planning and consenting to operational and regulatory issues, and to navigate regulatory developments. We have particular expertise in key operational and regulatory areas of the electricity market, such as the Transmission Pricing Methodology, Power Purchase Agreements, and the Electricity Industry Participation Code.

Our ability to build relationships with key stakeholders, including broader community interests, is an important aspect of our service. In particular, our lawyers work closely with our Māori buisness specialists on engaging with Iwi.

We are also specialist advisers on the Emissions Trading Scheme which is increasingly relevant to power usage and pricing.

Work Highlights

Lodestone Energy solar project

We advised Lodestone on all aspects of the development of New Zealand’s largest solar power project, which will see utility-solar farms constructed in five locations with around 360,000 solar panels. The aggregate generating capacity of the farms will be approximately 200MWdc.

Our work on this complex project included site acquisitions, a fully subscribed equity raise, corporate structuring, engineering, construction and major equipment procurement, grid connection contracts and non-recourse debt funding.

The project has set the benchmark for solar energy generation development in New Zealand, and won in two categories at the 2023 INFINZ Awards.
