The global push toward decarbonisation is transforming industries at an unprecedented pace—and maritime transport is no exception. Ports, long considered hubs of trade and logistics, uk news24x7 are now under increasing scrutiny due to their environmental impact. Ships docked at ports continue to run auxiliary engines, emitting harmful pollutants into surrounding communities.
This is where onshore power supply (OPS)—also known as cold ironing—comes in as a game-changing solution.
And at the center of this innovation is the Alfion-Infra project, a pioneering initiative that not only deploys OPS infrastructure but also introduces a Distribution System Operator (DSO)-driven business model to revolutionize how port electrification is managed.
What Is Onshore Power Supply (OPS)?
Onshore Power Supply allows ships to connect to shore-based electricity while docked, enabling them to shut down onboard diesel generators.
Key Benefits of OPS:
- Reduces CO₂, NOₓ, and SOₓ emissions
- Improves air quality in port cities
- Minimizes noise pollution
- Supports EU climate targets
According to industry insights, OPS is critical to achieving Europe’s climate neutrality goals, with ports contributing significantly to maritime emissions.
The Alfion-Infra Project: Overview
The Alfion-Infra (Alternative Fuel Implementation in Igoumenitsa Port) project is a flagship European initiative aimed at accelerating the deployment of OPS infrastructure.
Key Highlights:
- Location: Port of Igoumenitsa, Greece
- Handles ~2.5 million passengers and 250,000 trucks annually
- Includes multiple high-voltage and low-voltage shore connection points
- Designed for passenger and Ro-Pax vessels
The project integrates engineering, procurement, installation, and grid connectivity into a unified framework.
It is a collaborative effort involving port authorities, energy operators, academic institutions, and private companies.
Why Port Electrification Matters
Ports are essential to global trade, but they are also hotspots of pollution. Ships at berth rely on diesel engines for:
- Lighting
- Heating
- Cargo operations
These activities release pollutants that negatively impact human health and the environment.
Environmental Impact:
- Increased respiratory diseases in coastal regions
- Contribution to climate change
- Degradation of urban air quality
Electrification through OPS directly addresses these challenges, making ports cleaner and more sustainable.
The Challenge: Why OPS Adoption Is Slow
Despite its benefits, OPS adoption has faced several barriers:
1. High Capital Costs
Infrastructure installation requires significant upfront investment.
2. Lack of Clear Business Models
Uncertainty around cost recovery and pricing mechanisms discourages stakeholders.
3. Coordination Complexity
Multiple parties are involved:
- Port authorities
- Shipping companies
- Electricity providers
4. Grid Integration Issues
Ports demand massive power—sometimes equivalent to small cities.
These challenges highlight the need for innovative solutions like the DSO-driven model.
Traditional OPS Business Models
Before Alfion-Infra, OPS systems typically followed port-led models:
1. Intermediary Model
- Port authority acts as middleman
- Applies markups on electricity
2. Facilitator Model
- Ships buy electricity directly
- Port provides infrastructure
Limitations:
- Inefficient coordination with electricity grids
- Pricing inconsistencies
- Investment risks
These shortcomings paved the way for a more integrated approach.
The DSO-Driven Business Model Explained
The Distribution System Operator (DSO) is responsible for managing electricity distribution networks.
In the Alfion-Infra project, DSOs take a central role in OPS deployment.
