About us

Clean Energy for a Fairer and Healthier World.

We’re New Zealand’s largest renewable energy generator and a major retailer.

Join us Latest share price

Meridian Energy is one of Aotearoa New Zealand’s largest listed companies. We sell more electricity to customers, large and small, than any other electricity company and we generate around a third of the country’s electricity needs – all from renewable sources.

We’re also building new projects to stay ahead of the growing demand for electricity. This will help customers to reduce their emissions and ensure New Zealand has the advantages of a green economy, fuelled by renewable energy.

As a retailer we sell electricity to homes and businesses through two brands – Meridian and Powershop – and we’re committed to providing even greater value to them through new and more flexible energy solutions.

Making power matter

Our purpose is Clean Energy for a Fairer and Healthier World. Generating affordable, reliable, renewable energy is vital to a sustainable future, and Meridian has the scale and resources to help secure a clean energy future that helps people thrive and leaves our planet in better shape for future generations.

  • Solar panel

    Generating power

    We generate around 30% of New Zealand’s electricity – and all from 100% renewable sources. Meridian owns and operates seven hydro power stations and six wind farms. We also have power purchase agreements with a number of customers that see us own and operate commercial-scale solar on customer properties and sell the generation back to the customers.

    Retailing electricity

    Meridian is one of New Zealand’s largest retailers of electricity. We supply power to more than 350,000 residential and business customers across the country through our Meridian and Powershop brands.

  • Customer care

    Helping customers in hardship

    Today’s cost of living is a real issue for many Kiwis across Aotearoa. To help our most vulnerable customers, we’ve created an Energy Wellbeing Fund with a $5 million investment that supports 5,000 Meridian and Powershop households. The fund provides support through bill credits and payment plans, as well as assists with in-home assessments and interventions in appropriate situations – from curtains, to insulation and heat pumps.

  • Supporting Communities

    Supporting communities

    We’re actively supporting the communities around our generation assets. Meridian is giving back through employment and business opportunities, sponsorships, community events, access to outdoor recreation and our Power Up Community Funds. Since 2010 we’ve invested $10 million through these local funds to support community-led projects, making tangible differences where they matter most.

    We’re also driving positive change across Aotearoa with our Community Decarbonisation Fund. Since 2022 we’ve allocated almost $3 million to initiatives that help community groups reduce costs and emissions through EVs, solar panels and boiler conversions. And Meridian stands proudly alongside KidsCan as its principal partner. With our support, KidsCan ensures that 55,000 school kids daily have access to food and essential items like jackets, shoes, socks and health products.

    Building new generation

    The growing electrification of transport, heating and industrial processes (among many other things) will increase demand for electricity and speed our path to a zero carbon future.

    We’re committed to playing our part by building seven new renewable energy projects by 2030. These include wind farms in Hawke’s Bay, Wairarapa and Manawatū, an energy park (battery and solar) in Northland and a solar farm northwest of Christchurch.

  • Innovation icon

    Energy innovation

    While we operate some iconic hydro stations, we also recognise that the electricity system is being fundamentally changed by the availability of new technology – things like EVs, home solar, EV chargers that can put stored energy back into the grid and billing systems that can give customers more choice over when they use power.

    Meridian is helping customers make the most of these and other new opportunities. It’s all about giving them more value, making this value accessible to more New Zealanders and taking pressure off the electricity system in peak periods or when lake levels are low.

  • Smart Meter v2

    Demand flexibility

    We have agreements in place with large industrial users, such as New Zealand’s Aluminium Smelter and Open Country Dairy, that see Meridian compensate them for reducing their electricity consumption during peak periods or dry years when our hydro storage lakes are low.

    As New Zealand to continues to electrify we need to get smarter about when electricity is used. These are great examples of that work in action and the scale of these big industrial operations means a little saving can go a long way for residential customers.
