Overview
The New South Wales Government introduced the Energy and Other Legislation Amendment (Renewable Energy Infrastructure) Bill 2024 into the Legislative Assembly, proposing a formal statutory framework for the decommissioning, land rehabilitation, and financial security obligations attached to wind and solar energy projects. The Bill, reported on by Clayton Utz on 28 May 2024, closes a long-standing regulatory gap that has left landholders, developers, and their financiers exposed to highly variable end-of-life outcomes for renewable energy assets. Where the mining and resources sector in NSW has operated under formalised rehabilitation and bonding frameworks for decades, the renewable energy sector has until now relied primarily on planning conditions and privately negotiated contractual arrangements to manage closure obligations.
The practical consequence of this gap has been significant uncertainty. Decommissioning standards, bond amounts, and land restoration benchmarks have historically been determined project by project, creating inconsistent obligations across the sector and real financial exposure for landholders if developers fail to meet their commitments at end of life. The Bill addresses this directly by establishing three legislative pillars: mandated decommissioning and materials management for wind and solar infrastructure, formal land remediation requirements to restore sites to pre-development condition, and mandatory financial security in the form of decommissioning bonds or bank guarantees to underpin those obligations.
The Bill also proposes to amend the Protection of the Environment Operations Act 1997 (POEO Act) to include solar electricity works as a scheduled activity, meaning that State Significant Development solar projects will require an Environment Protection Licence (EPL) to operate. For environmental consultants, this combination of changes will reshape the planning, assessment, and operational compliance workflows required to support renewable energy clients from project inception through to site closure.
Key details of the Energy and Other Legislation Amendment (Renewable Energy Infrastructure) Bill 2024
The Bill amends a suite of existing NSW legislation, including the Electricity Infrastructure Investment Act 2020, the Environmental Planning and Assessment Act 1979, the Environmental Planning and Assessment Regulation 2021, and the State Environmental Planning Policy (Transport and Infrastructure) 2021, in addition to the POEO Act 1997. The amendments create a cohesive end-of-life framework that sits alongside existing planning approvals rather than replacing them. This is a deliberate design choice: the statutory remediation and bonding obligations will operate in parallel with development consent conditions, creating a dual layer of accountability for asset owners and operators.
On land rehabilitation, the Bill requires that land disturbed by renewable energy infrastructure be restored to its pre-development condition. The scope of this obligation is technically broad. It encompasses the restoration of original soil profiles, the reinstatement of pre-existing landforms, and the re-establishment of drainage patterns and waterway flows that existed prior to construction. For large solar and wind farms, which routinely involve earthworks across hundreds of hectares, this is a substantial technical undertaking. It also creates a direct obligation to establish and document pre-development baselines before construction commences, because without a defensible baseline, neither the developer nor the regulator can confirm that the rehabilitation target has been met. The Bill therefore creates a retroactive incentive to invest in thorough pre-construction environmental characterisation.
The financial security provisions require developers to provide upfront security, such as bank guarantees or decommissioning bonds, to cover the full estimated cost of decommissioning and land remediation. This mirrors the bonding regime applied to mining operations under the Resources and Energy framework in NSW, where security amounts are calculated against independently verified cost estimates. Because the bond amount will be tied to a costed decommissioning and remediation programme, environmental practitioners will need to produce auditable, defensible cost models that accurately reflect the volume of infrastructure to be removed, the extent of soil disturbance, and the complexity of rehabilitation works. Projects that are under-bonded expose developers and financiers to regulatory liability; projects that are over-bonded tie up capital unnecessarily and affect project economics.
The amendment to classify solar electricity works as a scheduled activity under the POEO Act is significant in its own right. An EPL imposes ongoing statutory obligations including environmental monitoring, pollution incident reporting, annual return lodgement, and compliance with licence conditions that can be updated by the Environment Protection Authority (EPA) over the life of the project. Breaching EPL conditions attracts serious statutory penalties under the POEO Act. For solar developers that have previously operated under planning conditions alone, this represents a material increase in their compliance burden and introduces a new regulatory relationship with the NSW EPA as the ongoing licensing authority.
Australian context: how the NSW Bill aligns with and extends existing rehabilitation frameworks
The regulatory philosophy underpinning the NSW Bill is not new in the Australian context. Mandatory rehabilitation bonds and land restoration standards have been standard features of mining regulation across Australian states for many years. In Queensland, land rehabilitation and financial assurance obligations are governed primarily by the Environmental Protection Act 1994, with financial provisioning requirements administered under the Mineral and Energy Resources (Financial Provisioning) Act 2018.
