Case Study: Hall’s Group Accelerates Sustainable Logistics with Total Utilities and Lodestone Energy
Overview
Since 2008, Total Utilities has been a trusted energy and procurement partner to Hall’s Group, one of New Zealand’s largest cold chain logistics providers. In 2025, this longstanding partnership reached a major milestone when Total Utilities supported Hall’s adoption of Lodestone Energy’s virtual solar model—an innovative renewable electricity solution designed to reduce emissions, stabilise long-term energy costs, and future-proof the company’s nationwide operations.
Client Background
Hall’s Group, owned by the Talley’s Group, operates a significant refrigerated transport and cold storage network across New Zealand. Its footprint includes:
- Eight cold storage facilities
- Nine logistics depots across both islands
- A fleet of more than 640 specialised vehicles
- Over 700 employees
With major hubs in Tauranga, Napier, Wellington, Christchurch, and Invercargill, Hall’s plays a critical role in maintaining the country’s food supply chain. Its leadership team has a clear long-term strategy: build a more sustainable, cost-efficient logistics network that aligns with customer expectations for low-carbon supply chains.
The Challenge
Hall’s energy demand is both high and mission critical, driven by continuous refrigeration loads across its facilities and vehicle network. The business sought a solution that could:
- Reduce exposure to volatile electricity prices
- Support its sustainability and emissions reduction commitments
- Provide a robust financial pathway for long-term energy planning
- Avoid operational disruption
Given the scale of Hall’s network and its continuous power needs, any solution needed to be reliable, future-oriented, and backed by strong analytical validation.
Total Utilities’ Approach
Total Utilities worked closely with Hall’s executive leadership to design and test a comprehensive financial and strategic business case for adopting Lodestone Energy’s virtual solar model.
Our work included:
1. Long-Term Pricing and Risk Analysis
We modelled long-term electricity cost trajectories and compared renewable supply scenarios against traditional procurement models. This analysis highlighted the pricing stability and hedging benefits of Lodestone’s solar-backed supply.
2. Security and Reliability Assessment
We assessed the operational implications of integrating certified renewable electricity into Hall’s distributed cold chain network, ensuring no compromise to 24/7 refrigeration requirements.
3. Alignment with Sustainability Strategy
We evaluated the emissions reduction benefits in the context of Hall’s wider decarbonisation roadmap and customer-driven expectations for climate-aligned logistics partners.
4. Executive Confidence Building
By presenting evidence-based insights, scenario modelling, and risk mitigation pathways, Total Utilities enabled Hall’s leadership to confidently proceed with a progressive, sector-leading energy purchasing strategy.
The Solution: Lodestone’s Virtual Solar Model
Hall’s entered into a long-term renewable electricity supply agreement with Lodestone Energy, supported by Total Utilities’ commercial and strategic advisory. Lodestone will supply Hall’s through its expanding portfolio of utility-scale solar assets, including:
- The newly commissioned Whitianga solar farm
- The Clandeboye development under construction
- An additional soon-to-be-announced solar site
The agreement enables Hall’s to offset the electricity used across its national operations with fully certified renewable energy, ensuring long-term cost stability and meaningful emissions reduction.
Impact
For Hall’s Group
- Stabilised long-term energy costs through price-certain renewable supply
- Reduced carbon footprint, supporting customer sustainability goals
- Strengthened reputation as a forward-thinking logistics provider
- Future-aligned energy strategy supporting nationwide growth
Chief Executive Gareth McFarlane described the agreement as a natural evolution of Hall’s long-term strategy to build a more sustainable and cost-efficient network—one that “genuinely makes a difference” for both the company and its customers.
For New Zealand’s Renewable Energy Landscape
Hall’s joins a group of major organisations adopting Lodestone’s model, alongside companies such as The Warehouse Group and Ingham’s. This contributes to a pipeline of more than 1,000 GWh of annual solar generation, accelerating access to affordable, low-carbon electricity across the country.
A Strengthened Partnership
For over 15 years, Total Utilities has supported Hall’s with strategic energy procurement and advisory services. This latest project underscores the value of a collaborative, long-term partnership built on trust, shared vision, and a commitment to innovation.
By guiding Hall’s through a rigorous assessment and implementation process, Total Utilities helped the organisation confidently transition to a renewable energy solution that supports both commercial outcomes and New Zealand’s wider low-emissions future.
