Current Opportunities
Interim Asset Manager
Acre is partnering with a fast-growing low-carbon energy business to appoint an Interim Asset Manager for a focused 3-4 month engagement.
This is an opportunity to join a growing district heating business as it continues its transition from contractor to long-term asset owner. The role will sit within the Asset Management function and report directly to the Assets & Utilities Director.
The successful candidate will take ownership of three priority workstreams, with a strong focus on operational efficiency, contract management and asset performance.
Key areas of responsibility:
O&M Agreements
- Review the status of O&M agreements across the asset portfolio
- Identify agreements requiring finalisation, renewal or implementation
- Work with O&M teams to finalise terms and coordinate internal sign-off
- Establish and maintain a clear tracker of O&M KPIs, risks and gaps
Return Temperature & ASHP Commissioning
- Work with O&M and site teams to identify the causes of elevated network return temperatures
- Coordinate remedial actions to bring temperatures within the required range for ASHP commissioning
- Track performance and commissioning milestones
- Turn complex operational data into simple, actionable reporting
- Escalate contractual or commercial barriers where required
Contractual Notices
- Draft and issue contractual notices across heat supply, O&M and customer connection agreements
- Maintain a clear log of deadlines, obligations and notice statuses
- Liaise with investment, legal and commercial colleagues as required
What we're looking for:
We're keen to speak with candidates who have experience in asset management or contract management within energy infrastructure, district heating or utilities.
You'll ideally have:
- Experience implementing or administering O&M agreements for energy or infrastructure assets
- A practical understanding of district heating network operations and return-temperature performance
- Experience drafting or administering formal contractual notices
- Strong organisational skills and the ability to manage multiple workstreams against tight deadlines
- Excellent communication skills, with confidence working across contractors, operational, legal and commercial stakeholders
If this sounds like a good fit, or you'd like to find out more, please reach out directly to Jesse Harford at jesse.harford@acresearch.com.

Our Most Valuable Resource Isn't in the Ground
At 3:30pm on November 5, 2015, a tailings dam near Mariana, Minas Gerais, Brazil began to leak. The Fundão Dam, operated by Samarco and built to store waste from the Germano iron ore mine, sat in the hills above the village of Bento Rodrigues. By 4:20pm, the leak had become a catastrophic rupture.

An estimated 43.7 million cubic metres of mine tailings surged into the Doce River. The toxic sludge engulfed Bento Rodrigues and Paracatu de Baixo, killing 19 people, displacing thousands, and contaminating hundreds of kilometres of waterways before reaching the Atlantic Ocean. It remains Brazil’s worst environmental disaster. The social, environmental, and economic impacts are still being felt and will likely persist for generations.
Four years later, the Brumadinho tailings dam disaster, also in Brazil, caused by the sudden collapse of an iron ore waste dam, killed 270 people. At precisely the moment when minerals were becoming central to the global energy transition, mining found itself in the spotlight for all the wrong reasons.
The industry response was significant.
In 2020, the Global Industry Standard on Tailings Management (GISTM) was launched by the International Council on Mining and Metals, the United Nations Environment Programme, and the Principles for Responsible Investment. It introduced a globally recognised framework built on zero harm, board-level accountability, independent oversight, transparent disclosure, and planning for worst-case failure scenarios.
Alongside this, the Mining Association of Canada’s Towards Sustainable Mining (TSM) standard has also become a widely adopted industry framework over the last 20 years, focusing on continuous performance improvement across environmental and social responsibility, including tailings management, community engagement, and site-level accountability.
Across the sector, leadership teams have started to rethink and reshape their relationship with the land, communities, investors, and employees.
But standards and frameworks alone do not create responsible mining. People do.
