How Project Finance Actually Works: The Capital Stack
A common misconception is that an investor — whether a foreign company making an FDI, or a private partner in a PPP — must bring the full capital for a project from their own pocket. In reality, project finance is almost never 100% investor equity. Every major infrastructure project in the world is financed using a combination of capital layers, each with different risk levels, different return expectations, and different sources. This combination is called the Capital Stack.
Understanding the capital stack is critical because it explains why investors ask for guarantees, why banks must be involved, and why government has a role even when a project is "private". It also explains what TICGL advises on: helping each party understand what layer of the stack they occupy, what risk they bear, and what return or protection they need in exchange.
When an investor commits equity to a project — say USD 20 million in a USD 100 million energy IPP — they are taking the highest-risk position in the capital stack. If the project fails or the off-taker (TANESCO) stops paying, the equity investor loses their money first. This is why investors demand assurance mechanisms — what can be termed dhamana — before they commit.
But the equity investor is only one part of the picture. The lenders — commercial banks and DFIs who provide 50–60% of project cost as senior debt — also require guarantees before they will lend. They need to know: Who will repay if the project's revenues fall short? Who stands behind the off-taker's payment obligations? What happens if the government changes the regulatory framework mid-project? These questions are answered through a structured set of credit enhancement and risk mitigation instruments.
| Instrument | What It Does | Who It Protects | Tanzania Example / Source | TICGL Advisory Role |
|---|---|---|---|---|
| Power Purchase Agreement (PPA) | Long-term contract guaranteeing the off-taker (TANESCO) will buy electricity at an agreed price for 15–25 years | Equity investor + senior lenders | Songas PPA: 20-year agreement, 96% plant availability, TZS 11T fuel savings | TICGL advises on PPA structure, tariff benchmarking, and TANESCO credit risk mitigation strategies |
| Partial Risk Guarantee (PRG) | World Bank / AfDB guarantees specific risks (government contract breach, regulatory risk, transfer risk) so private lenders are protected | Senior lenders / DFIs | World Bank PRG used in JNHPP DFI financing; applicable to energy and transport PPPs | TICGL identifies which PRG products are available and structures applications to WB/AfDB on behalf of project sponsors |
| Viability Gap Funding (VGF) | Government or development partner provides 20–40% of capex as grant to make commercially marginal projects bankable | Equity investor (reduces equity needed) + senior lenders (improves debt serviceability) | India NIP model; Tanzania proposal: Tanzania Infrastructure Viability Fund (TIVF) | TICGL advises on VGF eligibility, structures VGF applications, and helps design the Tanzania Infrastructure Viability Fund architecture |
| Escrow / Revenue Ring-Fencing | Project revenues flow into a dedicated, legally ring-fenced account managed by an independent trustee — ensuring lenders are repaid before any surplus is distributed | Senior lenders + mezzanine providers | Kenya LTWP dedicated PPA payment account; Nigeria port concession escrow | TICGL structures escrow account frameworks and advises on trustee arrangements for Tanzania PPP transactions |
| Political Risk Insurance (PRI) | MIGA (World Bank), DFC, or private insurers cover losses from expropriation, currency transfer restrictions, political violence, or contract breach | Equity investor | Available for all Tanzania private investment via MIGA; particularly relevant for extractives and energy | TICGL advises foreign investors on MIGA eligibility and premium structures; facilitates PRI applications for Tanzania projects |
| Currency Hedge / Swap | Protects investors and lenders from TZS depreciation risk — ensuring that USD-denominated debt service can be met from TZS project revenues | Foreign equity investors + international lenders | AfDB partial currency guarantee; BoT FX swap facility (proposed); Morocco LNG USD-linked PPA | TICGL advises on currency risk structuring and advocates for BoT FX swap facility establishment for infrastructure SPVs |
| Government Equity / Co-investment | Government (via TIC, TPDC, or Ministry) takes an equity stake in the SPV — signalling political commitment and improving investor confidence | All capital stack layers (reduces perceived political risk) | TPDC stake in LNG SPV; government equity in DART BRT; SGR partial public equity | TICGL advises on optimal government equity ratio and helps structure government co-investment terms that do not crowd out private capital |
| ICSID / International Arbitration Clause | Ensures that if a dispute arises between government and investor, it is resolved under internationally recognised rules (not domestic courts alone) — essential for international lender comfort | Equity investor + senior lenders | Tanzania LNG project agreements; PPP Act 2024 amendments include international arbitration provisions | TICGL ensures all TICGL-advised PPP transaction structures include ICSID/UNCITRAL provisions and advises on dispute resolution frameworks |
TICGL's Role: From Research to Structuring to Mobilisation
The structural gap between Tanzania's investment needs and actual capital mobilisation is not primarily a problem of investor appetite — it is a problem of institutional capacity, project preparation, and financial structuring expertise. TICGL addresses this gap through three integrated functions: independent economic research that establishes credibility; transaction advisory that structures projects for bankability; and policy advocacy that reforms the enabling environment.
When an investor — whether foreign (FDI) or local private partner (PPP) — approaches a Tanzania project, they face a fundamental question: how do I finance this project in a way that protects my capital, attracts co-lenders, satisfies government requirements, and delivers viable returns? TICGL's advisory role answers this question across five stages:
Why FDI Alone Cannot Close the Gap — And Why That is Not the Point
A critical insight from Tanzania's financing data is that even the most optimistic FDI trajectory — USD 6.6B in 2025, growing toward USD 10–15B by 2030 — cannot alone close a USD 11–15B annual investment gap. This is for a fundamental reason: FDI is equity, and equity is always a minority layer of project finance.
If the average FDI-financed project uses 25% equity, then USD 6.6B in FDI equity can support approximately USD 26B in total project investment — when structured with the right debt and blended finance layers on top. Conversely, USD 6.6B in equity that arrives without a supporting debt structure simply sits undeployed — which is exactly what the registration-disbursement gap measures. The 78% of registered FDI that does not disburse is not lost investor interest — it is equity that could not find a matching debt structure.
| Project Type | Typical Size | Equity (Investor) | Senior Debt | Blended / Concessional | Key Risk Instruments | TICGL Advisory Priority |
|---|---|---|---|---|---|---|
| Energy IPP (Gas / Solar / Wind) | USD 30M–500M | 20–25% (FDI / local equity) | 55–65% (DFI + commercial banks; 15–20yr tenor) | 10–15% (AfDB PRG, World Bank Scaling Solar, DFC) | PPA with TANESCO; EWURA tariff approval; TANESCO Payment Guarantee; political risk insurance | High Priority — energy deficit most critical |
| Transport Infrastructure (Roads / Ports / Rail) | USD 100M–2B | 15–25% (private consortium + government co-equity) | 50–60% (AfDB, JICA, World Bank project debt; DSE infrastructure bond) | 15–25% (VGF from TIVF; EU EFSD+; JICA ODA concessional) | DBFOMT / BOT concession agreement; toll revenue escrow; ICSID arbitration; currency hedge | High Priority — SGR, ring road, port expansion pipeline |
| Water & Sanitation (Municipal Utilities) | USD 5M–80M | 20–30% (utility equity / LGA co-investment) | 40–50% (DSE green bond / municipal bond; development bank) | 20–30% (DAWASA model; climate finance; KfW grants) | Revenue ring-fencing; municipal credit rating; CMSA bond listing; LGA revenue guarantee | Replicable model — 12 municipalities after DAWASA |
| Agro-Processing & Manufacturing (FDI) | USD 5M–100M | 25–35% (foreign investor equity) | 45–55% (CRDB, NMB, TIB, Afreximbank; 5–10yr) | 10–15% (IFC MSME facility; TIC investment incentives; export credit) | TIC registration; land tenure security; offtake agreements with processors/exporters; political risk insurance | Diversification priority — reduce extractives FDI concentration |
| LNG & Large Extractives | USD 1B–42B | 15–20% (international oil company consortium + TPDC) | 50–60% (export credit agencies: Eksfin, UKEF, US EXIM + commercial syndication) | 10–15% (DFI first-loss; host government production-sharing support) | Production-sharing agreement; export revenue ring-fencing; ICSID arbitration; government stabilisation clause; offtake agreements (Asian LNG buyers) | Transformational — LNG FID is East Africa's largest prospective transaction |
| Social Infrastructure (Schools, Hospitals) | USD 2M–30M | 10–15% (PPP partner equity) | 30–40% (development bank; Islamic finance / Sukuk) | 40–50% (VGF essential; donor grants; Islamic Development Bank OIC) | Availability payment PPP structure; government payment covenant; PPPC concession agreement | VGF critical — commercial revenue insufficient without government payments |
Tanzania at a Decisive Development Juncture
Tanzania stands at a decisive juncture in its development history. The Fourth Five-Year Development Plan (FYDP IV, 2026/27–2030/31) and DIRA 2050 set out an audacious transformation trajectory: GDP reaching USD 121 billion by 2031, and a USD 1 trillion economy by 2050. Achieving this requires mobilising USD 11–15 billion every year in new investment — a target that public finances alone cannot remotely approach.
This report presents a data-driven analysis of Tanzania's project finance landscape — and demonstrates how TICGL's research, advisory, and structuring capacity can help convert Tanzania's investment interest into actual capital flows. The central finding is that Tanzania's development financing challenge is not an absolute shortage of global capital — it is a structural failure of financial intermediation, project preparation, and institutional capacity.
Key Findings at a Glance
PPP mobilisation requires TZS 34T/yr (~USD 13B) vs PPPC's budget of TZS 1–2B — a 17,000× institutional gap that TICGL's advisory capacity partially bridges while institutional scaling is pursued.
Only 22% of registered FDI disburses (USD 1.72B of USD 7.7B in 2024). The other 78% stalls not from investor cold feet but from missing debt structure — the gap TICGL's structuring advisory directly addresses.
TRA collected TZS 32.26T in FY2024/25 (103.9% of target), but ~70% is recurrent expenditure — leaving only TZS ~9.7T for development vs a need of TZS 28–38T annually.
DSE market cap at ~11% of GDP vs SSA average of ~20%. No corporate bond market of scale exists. TICGL advises on which DSE instruments are suitable for infrastructure project bond structuring.
Banking sector has TZS 79.4T in assets but offers maximum 3–7 year tenors. Infrastructure needs 10–25 years. TICGL advises on DFI co-financing structures that solve this tenor mismatch.
SOEs generate ~TZS 2T in annual losses. TANESCO's TZS 400B/yr deficit is the single most critical off-taker risk for energy project finance. TICGL advises on payment guarantee and PPA structuring to de-risk energy investments despite TANESCO's weakness.
Macroeconomic Context & Development Financing Imperative
1.1 Tanzania's Development Ambitions: FYDP IV and DIRA 2050
Tanzania's development planning architecture is defined by two overarching frameworks. FYDP IV (2026/27–2030/31) targets sustained real GDP growth of 7–10% per annum, a nominal GDP of approximately USD 118–121 billion by 2031, and structural economic transformation anchored in industrialisation, human capital, and infrastructure. Total financing requirement: TZS 477 trillion (~USD 183–190 billion) — more than four times FYDP III's mobilisation — with 70% required from the private sector.
DIRA 2050 targets a USD 1 trillion economy by 2050, with per capita income reaching approximately USD 7,000. Annual investment mobilisation must reach USD 11–15 billion in the near term, scaling to USD 20 billion or more as the economy deepens.
The TZS 170 trillion PPP mobilisation target requires 84+ active projects and 401+ pipeline projects to reach financial close. TICGL supports this pipeline by: (1) providing independent economic analysis that gives international investors credibility about Tanzania's growth trajectory; (2) advising PPPC on which projects are most structurally suitable for PPP finance vs. sovereign debt; and (3) helping individual investors and project sponsors design the capital structure that makes their specific project bankable within Tanzania's current regulatory and financial environment.
1.2 The Financing Gap: Scale and Structure
TICGL's Development Financing Gap Analysis (2026) estimates the cumulative financing shortfall 2024–2030 at USD 68–88 billion — averaging USD 10–13 billion per year. This is a structural — not cyclical — gap: an institutional and intermediation failure that cannot be addressed by monetary policy alone.
| Indicator | Current Value (2024–2026) | Target / Benchmark | Status |
|---|---|---|---|
| FYDP IV Total Financing Requirement | TZS 477T (~USD 183–190B) | Mobilise by 2031 | Ongoing |
| Annual Investment Needed | USD 11–15B per year | Scale to USD 20B+ by 2030 | Gap |
| Private Sector Share | 70% of total (TZS 334T) | 51% via PPP = TZS 170T over 5 yrs | Critical |
| FDI Actual Inflow (2024) | USD 1.72B (+28% growth) | USD 10–15B/yr by 2030 | Below Target |
| FDI Registered vs. Realised Gap | TIC: 842 projects, USD 7.7B registered; 22% disbursed | Raise disbursement to 60%+ | Structural Problem |
| TRA Revenue (FY2024/25) | TZS 32.26T (103.9% of target) | Tax-to-GDP: 13.1% → target 16–18% | On Track |
| Recurrent vs. Development Split | ~70% recurrent / ~30% development | Invert ratio toward 50/50 | Reform Needed |
| Capital Market Cap (DSE) | TZS 23.99T (~11% of GDP, 2025) | FYDP IV target: TZS 31T (18%+ GDP) | Shallow |
| Private Sector Credit / GDP | ~16% (2024) | Target: 25%+ of GDP | Below Target |
| Banking Sector Assets | TZS 79.4T (2025); NPL: 4.1% | Tenor extended to 10–25yr for infra | Improving |
| PPPC Annual Budget | TZS 1–2B/yr | TZS 380–680B for USD 68B pipeline | Critical Deficit |
| SOE Investment vs Returns | TZS 90T invested; ~TZS 2T annual losses | Governance reform critical | ROI Failure |
Public Finance — Limitations & Structural Constraints
2.1 Tanzania Revenue Authority (TRA) — Revenue Mobilisation
TRA achieved TZS 32.26 trillion in FY2024/25 — 103.9% of its annual target — with strong momentum into FY2025/26 (TZS 9.31T in Q3 alone). Tax-to-GDP reached approximately 13.1%. Despite this progress, approximately 70% of TRA revenue is allocated to recurrent expenditure — leaving roughly TZS 9–10 trillion for development against an annual infrastructure requirement of TZS 28–38 trillion.
Precisely because public finance can only cover 30–35% of Tanzania's investment needs, TICGL's advisory work focuses on unlocking the 65–70% that must come from private sources. This means: advising government on which public funds to deploy as catalytic VGF rather than full project financing; advising investors on how to structure transactions that don't require government equity; and advocating for the institutional reforms (TANESCO turnaround, PPPC funding, PPP Act amendments) that expand the fiscal space for private investment without increasing sovereign debt.
2.2 Local Government Authorities (LGAs) — The Revenue Gap & the Municipal Bond Solution
Tanzania's 185 LGAs collected approximately TZS 419.5 billion in own-source revenue in H1 FY2024/25 — implying a full-year run rate of TZS 840B–1.5T. This is critically insufficient for local infrastructure financing. The DAWASA green water bond model — Tanzania's first municipal utility bond — provides the replicable template: if extended to 12 major municipalities, it could unlock TZS 800B–1.5T in local infrastructure financing over FYDP IV without additional sovereign borrowing.
2.3 State-Owned Enterprise (SOE) Inefficiency — The Hidden Fiscal Drain & the TANESCO Problem
The Government has accumulated TZS 90 trillion in cumulative public investment across its SOE portfolio, yet annual efficiency losses are estimated at approximately TZS 2 trillion per year. TANESCO's chronic deficit of approximately TZS 400 billion per year — and its history of delayed payments to IPPs — is the single most critical off-taker risk factor constraining energy sector project finance.
Tanzania cannot wait for TANESCO to be fully reformed before attracting energy investment — the power deficit is too urgent. TICGL advises energy investors on a set of TANESCO-bypass structuring tools that allow energy projects to proceed despite TANESCO's credit weakness:
