Plan and defend transmission investment.
From long-range system planning to preferred alignment — Optioneer gives transmission owners, system operators, and competitive developers the spatial intelligence to move faster, assess more options, and build a regulatory-grade evidence base from day one.

Platform highlights
Explore some core Electricity Transmission features of Optioneer. Visit our Platform page for a full, comprehensive overview of Optioneer’s capabilities.
Screening for electricity transmission.
Accelerate your network planning without assistance from engineering teams. By defining hundreds of potential connection points, you can independently evaluate upgrades, extensions, and new-build scenarios against real-world constraints.
Built for competitive bidding
Optioneer for Screening supports RIIO-ET3 business plan submissions and Accelerated Strategic Transmission Investment (ASTI) programme delivery. In the example of transmission system in the UK where 26 priority projects (~£20bn) require programmatic assessment approaches to meet 2030 targets.
Competitive tender bid development.
Fast-track route and cost proposals for competitive procurement processes where speed and credibility of initial proposals are critical. Produce defensible cost estimates and route options that would traditionally take months.
Supports the UK Competitively Appointed Transmission Owner (CATO) framework bids and third-party connection proposals.
In practise: 3 person army
A customer evaluated over 12,000 miles of transmission during a competitive window, in a few weeks, with a team of three.
Development for electricity transmission.
Optioneer accelerates the transition from corridor to consent by grounding engineering in real-world data. From automated route optimization to regulatory-grade audit trails, the platform ensures your project is technically viable and ready for global permitting.
Constraint & risk mapping
Eliminate weeks of GIS preparation with a ready-to-run data foundation. Define hierarchies and apply weights to generate corridors instantly. All constraints are dynamically linked to relevant legislation and permits.
Comprehensive database with key requirements from key statutory stakeholders. Includes National Polygon Service data for Crown Land and commercial properties, plus Continuum Industries’ BNG biodiversity baseline dataset.
Routing, siting & feasibility
Move from strategic corridors to centimeter-perfect alignments. Optimize paths at a granular level against all weighted constraints to verify buildability before committing resources.
A California utility uses Optioneer to evaluate 138 kV to 220 kV RoW upgrades.
OHL / UGC / HVDC hybrid design — switch asset types based on topographic, environmental, and policy constraints, with cost implications updating automatically
Existing rights-of-way (RoW) — assessment of widening, paralleling, and voltage uprating of existing corridors (e.g., 138 kV to 220 kV)
Tower placement and span analysis — key structure locations, crossing identification, and construction access feasibility
Reconductoring opportunities — evaluate higher-capacity conductors on existing infrastructure as an alternative to new-build
Multi-criteria option selection
Standardise your internal governance with defensible metrics. Thousands of flexible metrics allowing implementation of bespoke methodology (internal governance) as well as standard costing frameworks.
- Red-amber-green assessment for fatal flaw identification and multi-disciplinary review, including weighted decision methods
- Trade-off analysis — cost vs visual impact
- Detailed long-section view with locations of crossings, individual structures and individual impacts on each constraint
- CAPEX and OPEX estimates supporting AACE Class 4 (and Class 3 with engineer review)
Environmental & permitting support
Ensure your preferred option is actually permittable. Environmental constraints are part of route origination in Optioneer — not a check run after the option is already selected.
Optioneer supports ASTI programmatic assessment, Section 37 consent (Electricity Act 1989), DCO applications, and alignment with NPS EN-5.
Comparative environmental risk profiles — across all options, overlaying protected habitats, heritage assets, hydrological features, and landscape designations.
Constructability-aware routing — factor in access road requirements, terrain suitability, and construction corridor width so comparisons reflect real-world buildability.
Tower spotting and visibility analysis— assess candidate tower positions against visual impact constraints, including recreational areas, residential proximity, and key viewpoints.
EIA screening and scoping support — constraint maps, designated area summaries, impact tables.
Complete audit trail — timestamped record of constraints applied, options assessed, and decisions taken.
Built for your market
Engineering certainty for the most complex regulatory landscapes. Optioneer allows teams to rapidly evaluate millions of configurations to find the winning balance of cost, reliability, and deliverability within narrow solicitation windows.
