Power System and Network Planning
Enabling Resilient, Renewable-Ready Energy Systems
Our Power System and Network Planning services help governments, utilities, and operators understand future system needs and prioritise investments to meet decarbonisation, reliability and affordability goals. Using advanced modelling tools and deep technical insight, we deliver actionable plans to guide energy system evolution.
Power Development Planning
We help identify and sequence generation and network investments needed to meet future demand and reliability targets.
This supports cost-effective decarbonisation while ensuring system adequacy.
- Identify long-term capacity needs
- Optimise generation and transmission investment sequencing
- Align investments with national targets and reliability standards
We deliver.. models such as IES’s proprietary software PROPHET, and the non-proprietary platform PLEXOS and consult on national and regional development plans.
Variable Renewable Energy Integration
Our analysis evaluates the operational and system impacts of integrating wind, solar and other variable resources.
This is key to understanding reliability and security implications and flexibility requirements as renewable penetration increases.
- Production cost and curtailment modelling
- Assessment of ramping, inertia and frequency control needs
- Grid stability analysis under different penetration levels
We use tools like PLEXOS and PSSE to assess system balancing and grid performance.
Transmission Network Modelling
We conduct advanced modelling to assess future transmission needs under different energy transition scenarios.
This informs planning for efficient and timely grid expansion.
- Load flow and congestion analysis
- REZ development and interconnector studies
- Stability assessments for future scenarios
Typical tools include PSSE, PSCAD, and capacity expansion platforms.
Renewable Energy Mapping
We map resource potential and project viability to guide renewable energy zone development and investment decisions.
This ensures optimal use of land and infrastructure for clean energy growth.
- Geospatial resource analysis
- Site screening for project viability
- Support for REZ planning and investor decisions
We leverage open-source GIS platforms and resource datasets to produce practical development insights.
Decarbonisation Roadmaps
We develop transition pathways tailored to jurisdictional goals, considering technology, cost and policy constraints.
These roadmaps provide a structured approach to achieving net-zero targets.
- Scenario-based modelling and analysis
- Stakeholder consultation and strategy co-design
- Net-zero aligned policy and infrastructure pathways
Projects often involve tools like PLEXOS or PLANET in combination with institutional support.
