NatPower Marine delivers a fully integrated digital platform that turns port activity data, vessel behaviour, and energy economics into decisions — helping ports, shipping lines, and cargo owners navigate the most complex energy transition in maritime history.
From identifying opportunity to proving emissions savings — one connected platform.

The Scale
The maritime industry knows it must decarbonise. But ports cannot invest without vessel demand data, and shipping lines cannot electrify without port infrastructure. NatPower Marine breaks this deadlock — with capital, infrastructure, and the intelligence to prove the case.

Who We Serve
Our tools are built around the real commercial and operational decisions that each stakeholder must make on the path to decarbonisation — from the first investment conversation to verified ESG reporting.
“Which berths have the highest cold-ironing demand? What size energy storage do I need? What is my return on investment?”
NatPower Marine’s platform shows historical vessel traffic, docking hours, and energy demand at berth level — answering these questions from real data, not assumptions. Financial models produce bankable business cases ready for board approval, and the BESS Optimizer ensures no capital is wasted on over-sized infrastructure.
“What are my current and future penalty exposures? Where can I connect to shore power today? How do I demonstrate verified Scope 1 reductions to charterers?”
The Penalty Calculator quantifies exactly what FuelEU Maritime, EU ETS, and IMO CII non-compliance costs each vessel — today and in 2030. The Booking Platform lets vessels pre-book connections. Automated reporting delivers verified emissions evidence for ESG disclosures and charterer requirements.
“My ESG report is only as credible as my data. How do I give investors independent evidence that my logistics chain is genuinely decarbonising?”
When your shipping partners connect to NatPower Marine shore-power infrastructure, every kWh is metered and attributed. Automated Scope 1, 2, and 3 emissions reports give cargo owners independent, audit-ready data to satisfy investor and regulatory demands — without any action required on their part.
“Which vessels are actually using shore power? Which ports are meeting OPS targets? What is the aggregate emission reduction in my jurisdiction?”
The NatPower Marine reporting layer aggregates vessel activity across all connected ports into jurisdiction-level dashboards. Authorities monitor OPS utilisation, compliance rates, and aggregate CO², NOx, and SOx reductions — the evidence base for policy decisions and public reporting.
How It Works

Our Tools
Each tool solves a specific decision in the energy transition journey — and all connect to the same underlying data platform, so every output is consistent and every insight is grounded in the same source of truth.
The command centre for NatPower Marine’s global operations. An interactive map showing live and historical vessel movements, port and berth boundaries, OPS infrastructure status, and cold-ironing opportunity scores — giving decision-makers a single visual answer to “where should we invest next?”
A per-vessel financial analysis tool that translates shore-power adoption into a concrete commercial case. From a vessel’s actual operating profile, it models the full financial impact of electrification — fuel savings, avoided regulatory penalties, and net financial position year-by-year — with a one-click PDF for the boardroom.
The operational backbone of the charging network. Vessel masters pre-book shore-power connections before arrival. Port authorities manage station capacity, live session status, and revenue. Fleet managers coordinate across their fleet and track energy usage — all three roles operating from one integrated platform.
Designed for live client conversations. With minimal inputs, it produces indicative IRR, payback period, NPV, and emissions savings for any shore-power project — enabling NatPower Marine’s commercial team to move from “is this interesting?” to “here are the numbers” in the same meeting.
Shore power at scale requires smart energy storage to avoid expensive grid demand charges and maximise renewable generation. This tool simulates the full energy strategy for a port project — modelling live grid pricing, solar output, wind, and vessel power demand — to find the optimal battery configuration before any hardware is purchased.
The proprietary data backbone that powers every NatPower Marine tool. It ingests global vessel AIS data, calculates port activity — which vessel was at which berth, for how long, consuming how much energy — and serves that intelligence to every application. One consistent version of the truth across the entire platform.
An AI-powered discovery layer across the entire platform. Ask a business question — “which tool helps me calculate my penalty exposure?” — and the system searches the full application catalogue and knowledge base to recommend the right tool, explain what it delivers, who it is built for, and the exact steps to get started.
A dedicated financial modelling tool for the Italian market, where NatPower Marine Italia is advancing shore-power projects at major ports including Civitavecchia. Built around Italian grid tariffs, EU OPS Regulation timelines, and local commercial frameworks — producing outputs that Italian port authorities and infrastructure investors actually need to see.
The tool that makes the cost of inaction impossible to ignore. Enter a vessel’s operating profile and the calculator returns its current and projected penalty exposure across every relevant regulation — FuelEU Maritime, EU ETS, UK ETS, and IMO CII — with year-by-year projections as regulations tighten through 2030 and beyond.
The full-depth model for investment-ready conversations. Takes a shore-power project from concept to lender-ready — with multi-year P&L, IRR and equity return waterfalls, debt structuring, and sensitivity analysis. Built for conversations with infrastructure funds, development finance institutions, and green bond issuers. Available in multiple languages for NatPower Marine’s international operations.
For vessels transitioning to full electric, battery-swapping offers zero-emission energy delivery independent of fixed shore-power infrastructure. MarineVolt simulates the battery-container logistics network across a route — modelling how charged battery containers move between hub ports, spoke ports, and destination berths to keep vessels operating continuously with no downtime for charging.
Data Platform
NatPower Marine’s competitive advantage is not just the tools — it’s the underlying data. A purpose-built maritime analytics platform that integrates global vessel intelligence, energy modelling, and project governance into a single source of truth that becomes more valuable the more ports and vessels join the network.
Global vessel position history linked to port, terminal, and berth boundaries. Automatically determines which vessel was at which berth, for how long, and what it consumed — the foundation for every demand and emissions calculation across the platform.
Every port call disaggregated into cold-ironing energy, propulsion charging energy, and hotel load — the granular data needed for accurate emissions attribution, billing, and ESG reporting that stands up to investor scrutiny.
Per-project energy storage optimisation using vessel demand profiles, live grid pricing, and renewable generation data — ensuring every capital decision is grounded in operational reality rather than generic industry benchmarks.
A full infrastructure project lifecycle management layer — tracking every shore-power project from prospecting to commissioning with approval workflows, audit trails, and stage-gate governance across multiple geographies and regulatory environments.
Reporting produced from metered operational data — covering CII compliance trajectories, Scope 1/2/3 emissions breakdowns, and OPS utilisation rates — across multiple deployment environments for integrity and full auditability.
A managed registry capturing each vessel’s shore-power standard, connection capacity, commissioning status, and technology supplier — giving port authorities and operators a verified view of which vessels can connect today, and when the rest will follow.
The maritime energy transition is the largest clean energy challenge of the next decade. NatPower Marine is already building the infrastructure and intelligence to lead it.
