Power infrastructure design & engineering
The problem: Poorly designed projects stall during construction
As more renewables come online, energy asset development becomes increasingly complex. Operators must meet rigorous grid connection standards and market operator approvals that require both engineering and market-specific expertise.
Pure-play engineering firms excel at calculations but often lack the construction experience needed to design buildable systems. When a design problem like poor interface planning, overlooked site constraints, or faulty equipment is discovered during a build, it can blow out budgets, timelines, and contingencies.
In critical infrastructure, the stakes are higher. Design issues can create safety hazards, regulatory rejections, and liquidated damages. Operators can’t afford to invest in energy systems that don’t work in the real world.
Our solution: Energy assets engineered for the demands of critical infrastructure
We combine power systems engineering with proven delivery experience to navigate both the technical and the practical realities of realising new energy assets. Our end-to-end approach means we own the full asset lifecycle, from feasibility and engineering to delivery and operations.
Unlike pure-play engineering firms we design for buildability, accounting for site constraints, interface risks, equipment installation hurdles, maintenance practicalities, and the human challenges that arise during construction and operation.
We guide projects through complex grid connections and regulator approvals by selecting the right equipment, assessing feasibility before construction, and negotiating necessary technical compromises.
You avoid the approval delays, cost overruns, and the safety hazards that come from energy systems that aren’t engineered for the demands of critical infrastructure.
We own energy infrastructure projects from engineering to operation
Engineering services
Our engineering team helps energy operators design buildable power systems on SCADA/EMS infrastructure, navigate complex market approval and grid connection processes, and provide specialised support services:
- Feasibility studies and energy yield assessments
- Concept design and Front-End Engineering Design (FEED)
- Detail design and comprehensive technical specifications
- Power systems engineering and electrical systems design
- SCADA systems design and Energy Management System (EMS) design
- Grid connection support (R0/R1/R2 approval processes)
- Constructability reviews (audit existing designs for delivery feasibility)
- Owner's engineer services
- Technical due diligence
Project delivery
Integrated project teams handle procurement, construction management, and commissioning based on the delivery model (EPC, EPCM, PMC, Split Scope, etc.) that fits your capital structure and risk appetite.
- Project management and contract management
- Engineering design services and procurement services
- Logistics and construction management
- Site execution and equipment integration
- Commissioning and handover to operations
Facility Operations & Maintenance(O&M)
Ongoing operations and maintenance that capture operational insights, applying learnings to continuously improve asset lifespan and performance:
- Defects liability period (DLP) management
- Standalone operation and maintenance (O&M) services
- Equipment commissioning and maintenance
- Facility operation, monitoring, and performance optimisation
- 24/7 facility monitoring with digital twin deployment
- Warehousing, logistics, and root cause analysis
- QA/QC and continuous improvement
How we work
- Engage: We connect through conversations, procurement frameworks, or a RFQ and identify which delivery model fits your needs (EPC, EPCM,PMC, Split Scope, etc.)
- Diagnose: We assess project conditions such as site constraints, grid connection requirements, regulatory landscape, and financial/technical targets
- Design: We engineer buildable systems that account for site realities and meet planning permissions, grid applications, and technical specifications
- Deliver: Construction and commissioning conducted based on your chosen delivery model, with integrated project teams managing interface risk and ensuring performance
- Optimise: Post-commissioning support including DLP management, transition to long-term O&M, and performance data feedback into future project improvements
Design and deliver energy assets that perform as promised
Efficient delivery
Build projects based on site realities. Our practical experience means fewer mid-build surprises and faster delivery timelines. Project teams stay on through commissioning to ensure the assets perform as promised.
Regulatory compliance
Navigate complex approval and grid connection processes. Select equipment that meets technical requirements and test feasibility before construction to avoid approval delays and negotiate technical compromises confidently.
Continuous operational improvement
Use learnings from your commissioned facility to improve its operation. We’re there to optimise the long-term performance of your assets, not just fulfill a delivery brief.
Flexible delivery models
Choose the delivery model that fits your capital structure and risk appetite. From full turnkey EPC to tailored combinations of EPCM, Split Scope and owner-led project management, you get the level of risk transfer that fits your financing.
nxzen brings power systems expertise & end-to-end accountability
Engineering & delivery expertise
Our team is made up of lifelong energy professionals with decades years of renewable asset expertise. We understand grid connection requirements, site constraints, and the realities of building in regulated environments.
End-to-end accountability
Engineering, construction, and operations teams work as one integrated unit. One partner for strategy, execution, and optimisation means no finger-pointing between vendors when problems arise.
Grid operator expertise
We know how to navigate approval processes with grid operators. From selecting the right equipment to technical negotiations, we bridge the gap between your design and grid requirements.
Proven at scale
We've successfully delivered large-scale energy asset development, battery storage, and utility solar projects. We know what works on site, so when we design we’re thinking about constructability and operability from day one.
Strategy based on outcomes
Our post-delivery O&M model gives us a feedback loop to continuously monitor performance, address issues, and improve over time. Each project makes us better, and that improvement flows directly into your facility.
