Grid Connections

Enabling renewable energy developers and project owners to navigate the grid connection process with confidence from first feasibility assessment through to energisation.

Connect with confidence.  Deliver on time and on specification

Rennie’s Grid Connections team helps renewable energy developers, project owners and investors navigate the full grid connection process in Australia. We guide clients from early-stage connection strategy and feasibility through to power systems studies, commissioning and performance validation, providing the technical expertise and commercial insight to keep projects moving.

Our team combines deep power systems engineering expertise with strong relationships across the network operator and regulatory landscape. We help clients compress timescales, minimise connection risk, and secure the access standards that protect their investment — from the first connection enquiry through to commercial operation.

OUR GRID CONNECTIONS EXPERTISE

Connection Strategy & Feasibility

Our Connection Strategy and Feasibility offering helps clients make informed, confident decisions about how to approach the grid connection process — before committing to a formal application. We assess connection options, identify preferred connection points, and develop access strategies that give each project the strongest possible foundation, minimising abortive costs and protecting project timelines.

  • Connection feasibility
  • Network access strategy and option analysis
  • Connection point identification and comparison
  • Technology transition and strategic advice
  • Connection process navigation and application support
  • Stakeholder engagement with network operators and AEMO
  • Commercial negotiation support
Power Systems Studies

Our Power Systems Studies practice helps clients navigate the technical requirements of the connection process — from initial compliance assessment through to model development, validation and performance standard negotiation. We manage the end-to-end connection studies process on behalf of our clients, working directly with network operators and AEMO to achieve compliant, commercially optimal outcomes.

  • Connection application management and coordination
  • Grid code compliance studies, steady-state, dynamic and fault level
  • Generator Performance Standards assessment and negotiation
  • Power systems model development and benchmarking
  • Model acceptance testing and validation
  • RMS and EMT simulation studies
  • Performance standard negotiation with network operators and AEMO
Commissioning & Validation

Our Commissioning and Validation offering helps clients bring their generation and storage assets to commercial operation on time and in full compliance. We manage the commissioning program from planning through to performance validation — providing hold point oversight, compliance documentation and on-site technical support to ensure a smooth and timely transition to commercial operation.

  • Commissioning program planning and management
  • Hold point witnessing and documentation 
  • Performance validation testing
  • Compliance confirmation and reporting

Our Grid Connections expertise in focus

Multi-Project Connection Strategy for Solar and BESS Pipeline

A renewable energy developer engaged the team to provide connection strategy and feasibility advice across a pipeline of utility-scale solar and battery storage projects in New South Wales and Queensland. Our team assessed connection options across multiple sites in parallel, identified preferred connection points, and provided strategic guidance on Performance Standard requirements and network operator engagement, enabling the developer to prioritise its project pipeline with confidence and sequence its applications to protect approval timelines. 

Wind Farm and BESS Connection Studies

A renewable energy developer engaged the team to deliver comprehensive grid connection studies for a wind farm and Battery Energy Storage System in Western Australia. Our team managed the end-to-end connection studies process, delivering R0 and R1 compliance studies, power systems model development and dynamic stability assessments for both the wind and BESS components, and negotiated access standards with the network operator and AEMO on the developer’s behalf, providing the technical foundation to advance the project through connection approval.

Solar Farm and BESS – Connection to Commercial Operation

A global renewable energy developer engaged the team across the full connection lifecycle of a solar farm and Battery Energy Storage System, from initial grid connection studies through to commissioning support and performance validation. Our team managed hold point testing, performance validation trials and compliance documentation in accordance with AEMO and network operator requirements, coordinating across the project team, EPC contractor and equipment suppliers to bring the project to commercial operation on schedule and in full compliance with its access standards.
