Investment governance for infrastructure companies
From investment needs to defensible portfolio decisions.
RIN is a methodology and digital framework that connects the register of investment needs, their evaluation, portfolio selection and post-implementation review into one governed cycle.
The problem
An investment plan is often not a selection. It is a sum of requests.
When renewal, development and mandatory investments are argued in different terms, the budget ends up being cut rather than optimised. Nobody looks for the best combination.
A sum, not a choice
Each plant submits its own list, and the ranking is often set by urgency or negotiating power.
Subjective scoring
Two assessors score the same proposal differently, and nobody knows how much that changes the final portfolio.
Incomplete evidence
Renewals lack the cost of not acting, developments lack verifiable benefits. Missing data silently turns into low priority.
No feedback loop
Once an asset is in service, nobody checks whether it delivered what was promised. The same estimation errors repeat.
Approach
The product is not software. The product is a decision system.
Four layers that work together. The technology can change; the decision logic stays the same.
Governance
Rules, roles and authority limits. The investment committee screens, the investment board decides on the portfolio, and every decision leaves a trail.
Data
One standard cover sheet, a register of investment needs with a unique ID, and checks on completeness and quality of evidence.
Decision
Three evaluation indices, competing scenarios and portfolio optimisation under real CAPEX and capacity limits.
Learning
Post-implementation review compares promised and actual results and recalibrates how the next proposals are assessed.
How it works
One cycle from need to verified benefit
Every investment keeps the same ID from start to finish. Today's decision becomes data for a better decision tomorrow.
- 01
Need and cover sheet
The proposal enters the long list, classified as renewal or development.
- 02
Indexation
Strategic, operational and financial-economic indices plus a risk class.
- 03
Short list and reserve
Ready proposals move on; the rest wait in a ranked reserve.
- 04
Scenarios
Portfolios built around different priorities, side by side.
- 05
Optimisation
The model finds the best feasible combination within the given limits.
- 06
Choice and rationale
The board settles contested cases and records why. The model does not decide for it.
- 07
Delivery and review
Investment pipeline, controlling and post-implementation review of benefits.
Why "robust"
Robustness is not a slogan. It can be measured.
A good decision holds when the assessor, the weights or the assumptions change. RIN tracks this in four dimensions.
Data quality
Completeness of cover sheets and quality of evidence. An unknown value is never counted as zero.
Assessor agreement
How much scores for the same proposal differ between experts, and what that does to the ranking.
Portfolio stability
Which investments stay selected in every scenario, and which ones are contested.
Operational evidence
Benefits verified by simulating how the whole system operates, not just declared by the proposer.
Demo
Change the budget and see what stays in the core
Twelve fictional investments, two of them mandatory. Each has a strategic (S), operational (P) and financial-economic (F) index. Three scenarios weight the indices differently, and every budget change recalculates the optimum for all of them at once. What all three select forms the portfolio core.
| Investment | Type | CAPEX (M €) | S | P | F | Balanced | Reliability | Strategy | Status |
|---|
Fictional data. A simplified MILP demo: each investment is a yes-or-no decision. Weighted index = weight S × S + weight P × P + weight F × F for the scenario. Value of an investment = weighted index × CAPEX, so every euro invested is valued by its project's index and unused budget has no value. The model looks for the combination with the highest total value within the annual CAPEX limit. Mandatory investments are always included and the exact optimum is found for each scenario. A real model adds year-by-year timing, capacities and dependencies between projects.
Who it is for
For companies that must invest responsibly and be able to defend it
Regulated prices, public obligations, ageing assets and a limited budget. That is where it pays to decide on the portfolio, not on individual projects.
District heating
Plants, networks, CHP and renewables, decarbonisation and efficient district heating.
Water utilities
Renewal of networks and treatment plants under regulated prices and reliability pressure.
Municipal services
City technical services with many small investments and a single budget.
Public infrastructure
Organisations for which a large specialised system would be a disproportionate investment.
Getting started
Step by step, from diagnostic to your own portfolio decisions
RIN Register
Diagnostic and register
Process mapping, a standard cover sheet, a register of investment needs and data quality checks.
RIN Decision
Evaluation and governance
Indexation, business case and counterfactual, rules for the investment committee and board.
RIN Intelligence
Portfolio and robustness
Scenarios, optimisation, analysis of scoring subjectivity and stability of the selection.
Runs in the Microsoft 365 environment you already have (Excel, SharePoint, Power BI). The decision logic is not tied to a platform.
Start with a diagnostic of your investment process
Within a few weeks you will see where decisions are made without data, where subjectivity is greatest, and what would change with portfolio-based selection.
