Public Sector Advisory

Infrastructure Finance & Modeling

Financially sustainable, bankable infrastructure for cities, utilities, and public agencies.

White Textured Surface

Infrastructure decisions lock in financial and service outcomes for decades. Many projects fail not because the engineering is weak, but because the financial foundation is incomplete: unrealistic forecasts, no clear cost-recovery pathway, weak tariff logic, or poorly structured PPPs.

ACS SYNERGY supports governments, municipalities, utilities, and development partners with infrastructure finance, modeling, and investment planning that makes projects affordable, fundable, and financially sustainable. We combine deep financial modeling expertise with the sector and urban-development experience of our partners to help clients design infrastructure that works on the ground and on the balance sheet.

The Role of Infrastructure Finance & Modeling

The Role of Infrastructure Finance & Modeling

Cities and public utilities are facing an increasingly complex environment:

Urban populations and service expectations are rising

​

Climate resilience and environmental standards are tightening

​

Assets are aging while capital budgets remain constrained

​

Investment needs far exceed available fiscal space

What will this project really cost over its full lifecycle?

​

What tariff or revenue model is needed to operate and maintain it?

​

How do we balance affordability with cost recovery and distributive fairness?

​

What risks sit with the public sector, private sector, and users?

​

Is PPP / P3 appropriate, and if so, how should it be structured?

​

What is the long-term fiscal impact on the city or national government?

Decision-makers need to answer questions such as:

Our models and advisory work bring evidence and clarity to these questions so leaders can compare options, test scenarios, and build financially viable, resilient infrastructure portfolios.

What We Deliver

What We Deliver

We support the full infrastructure lifecycle—from early concepts through feasibility, transaction design, and implementation.

Infrastructure Financial Modeling

We build detailed, multi-year financial models that quantify project costs, revenues, risks, and funding requirements for:

Urban and municipal infrastructure programs

Transport and mobility systems (bus, BRT, rail, roads)

Water supply, wastewater, and stormwater services

Solid waste management and sanitation projects

Energy and other utility assets

Typical outputs include:

​

Investment and lifecycle cost assessments (CAPEX + OPEX)

Revenue and tariff projections where user fees apply

Scenario and sensitivity analysis (demand, cost, inflation, FX)

Long-term affordability and fiscal-impact assessment

Financial KPIs: NPV, FIRR, DSCR, payback, subsidy needs

PPP / P3 Financial Advisory

Where public-private partnerships are considered, we help governments test whether PPPs create value and how they should be structured.

Our work covers:

​

PPP feasibility and value-for-money analysis

Public-sector comparator (PSC) modeling

Risk allocation and contract structure from a financial standpoint

Affordability analysis for government commitments

Financial model support during market sounding and negotiation

Our aim is to ensure PPPs are financially sound, risk-balanced, and transparent.

PPP / P3 Financial Advisory

Multi-Year Investment & Capital Planning

Infrastructure must be planned within fiscal and institutional reality, not as stand-alone wishlists.

We support clients with:

​

Prioritization and sequencing of projects

Multi-year capital investment plans aligned with fiscal space

Integration of climate and resilience costs into project pipelines

CAPEX-to-OPEX transition and funding strategies

Funding mixes: grants, concessional finance, commercial debt, and PPPs

This helps cities and utilities build credible, investment-ready capital programs instead of isolated projects.

Feasibility & Economic Modeling

Donors, ministries of finance, and municipal councils require evidence before committing scarce capital.

We provide:

​

Financial and economic feasibility studies

Cost–benefit analysis and economic internal rate of return (EIRR)

Demand analysis and service-gap assessment

Affordability and distributional-impact analysis (who pays, who benefits)

Viability-gap identification to inform subsidies and blended finance

Our work aligns with the standards and expectations of multilateral and bilateral development partners.

How We Work

How We Work

Evidence-Based Analysis

 


We start with data—costs, service gaps, demand, and institutional realities—and build models that reflect actual conditions.

Scenario-Driven Decision Support
 

We show decision-makers how projects behave under different demand, cost, tariff, and financing scenarios.

Integrated Sector & Finance Perspective


We work closely with urban planners, engineers, and sector specialists so that financial solutions are grounded in real-world technical design and service-delivery constraints.

Implementation Alignment


Our recommendations consider budget cycles, tariff regulations, institutional capacity, and donor requirements—so that what is modeled can actually be implemented.
