Discom Debt: The Offtaker Problem
The cost-of-capital gap said the Global South build is a financing problem, and that the largest driver of it is offtaker risk. This is that offtaker — a distribution utility that buys power it cannot fully collect for, and so cannot reliably pay the generators it buys from.
The miller owes the farmer for the grain, / the town owes both, and neither can be paid; / so round and round the debt runs, never home — / and the mill stands idle though the harvest’s made.
The Offtaker Is the Constraint
The cost-of-capital note ended on a single deferred variable: the off-taker. Sixty to ninety per cent of the Global South’s cost-of-capital gap is country and base-rate risk, and the largest, most concrete piece of that risk is whether the utility buying the power can actually pay for it. In most of the developing world, the honest answer is: not reliably. The distribution company is insolvent, and its balance sheet is the binding constraint on the entire build.
A private generator does not sell electricity to consumers. It sells to a single counterparty — usually a state-owned distribution company, or discom — under a long-term power-purchase agreement. That contract is only as good as the discom’s ability to pay, over twenty-five years, in local currency, through every political cycle. When the discom is chronically loss-making, the PPA is not a bankable asset; it is an IOU from an entity that already cannot meet the IOUs it has written. That is the offtaker problem, and it is why the cost of capital sits where it does.
The discom’s insolvency is not one risk among many; it is the mechanism that transmits every other weakness — distribution losses, political tariffs, weak collection — into the discount rate on new generation. Fix the offtaker and the cost of capital falls; leave it broken and no volume of cheap panels or concessional intent will get the project financed.
How a Utility Goes Broke
The mechanism is the same everywhere it appears. The discom buys power from generators at one price and is meant to sell it to consumers at another that covers its costs. Three things break that arithmetic. A share of the power is never billed or collected — lost to theft, technical loss, and weak metering, the aggregate technical and commercial (AT&C) loss. A further share is sold below cost, because tariffs are set politically and certain customers — agriculture, low-income households — are charged little or nothing. And the gap between the two is meant to be filled by a government subsidy that arrives late, in part, or not at all.
The result is a utility that loses money on a structural basis. It cannot fund itself, so it delays paying the generators, which accumulate overdue receivables and charge penal interest; the generators in turn delay paying their fuel suppliers. The unpaid obligation circulates through the chain without ever being extinguished — which is why Pakistan calls it exactly that, circular debt. It is not a liquidity blip; it is the steady-state output of selling power for less than it costs to buy.
The Same Problem, Many Names
Because the mechanism is structural rather than local, it shows up across the developing world under different labels — and its absence, where the state simply absorbs the loss, is just as instructive.
| Country | Local name | Scale (2025) |
|---|---|---|
| India | DISCOM accumulated losses | ₹7.26 lakh crore of borrowings; ₹2.74 lakh crore unsustainable. |
| Pakistan | Circular debt | PKR 2.4 trillion, ~2.1% of GDP; over two-thirds owed to power producers. |
| Iran | Outstanding dues | Rooted in unfunded energy subsidies of ~$127bn a year — among the largest relative to GDP anywhere. |
| China | (no equivalent) | State-owned enterprises absorb the losses on their own balance sheets, so no circular debt accumulates. |
China is the tell. It has the same politically-managed tariffs and the same distribution scale, but no circular debt, because its state-owned utilities and banks absorb the shortfall financially rather than passing it down an unpaid chain. The problem, in other words, is not that power is priced below cost — many systems do that — but that the loss is left to circulate unfunded through a commercial chain that private generators sit inside. Where the state eats the loss, the offtaker stays bankable; where it does not, the offtaker poisons the cost of capital for everyone downstream.
Why It Is the Binding Constraint
Trace the consequence forward and the offtaker problem sits at the centre of two of this framework’s doom loops at once. It is the solvency node of the distribution-loss loop — losses starve the discom of revenue, which prevents the investment in metering and network that would cut the losses. And it is the largest single input to the cost-of-capital gap — an insolvent offtaker means an un-bankable PPA, which means a high risk premium, which means the clean generation that would modernise the system never reaches financial close.
Uncollected revenue makes the discom insolvent; an insolvent offtaker makes every new PPA un-bankable; an un-bankable PPA carries a cost of capital that deters the investment which would have fixed the losses. The offtaker problem is where the distribution-loss loop and the cost-of-capital gap meet and reinforce each other.
The Positioning Read: Fix the Payment Chain First
Because the offtaker problem is the binding constraint, the highest-return intervention in Global South power is not another gigawatt of generation — it is making the utility that buys the power creditworthy, or routing around it. The work is unglamorous plumbing, which is precisely why it is under-supplied and high-leverage.
Metering, billing & collection
Prepaid and smart metering, and the systems that turn delivered power into collected revenue, attack the loop at its source. India’s RDSS smart-meter roll-out is the template — and the direct lever on AT&C losses.
Payment-security & guarantees
Payment-security mechanisms, escrow, and sovereign or multilateral guarantees that stand behind the discom’s obligation convert an un-bankable PPA into a financeable one — the credit-enhancement side of the cost-of-capital fix.
Cost-reflective tariffs & targeted subsidy
The structural cure is tariffs that cover cost with subsidy delivered directly and on time to those who need it — politically hard, which is why it recurs. Transition-incidence logic applies: visible, and therefore fragile.
Unenhanced exposure to a broke discom
A PPA with an insolvent offtaker and no credit enhancement is the risk the cost-of-capital gap is pricing. It is also why captive power and behind-the-meter generation — bypassing the discom entirely — command a precedent-setting premium.
The uncomfortable truth the offtaker problem exposes is that the Global South energy build is gated less by anything upstream — generation, technology, resource — than by the solvency of the entity at the bottom of the chain that is supposed to collect the money. Make the discom creditworthy and the cost of capital falls, the PPAs become bankable, and the investment arrives. Leave it broke and the whole structure above it stays stranded, no matter how cheap the panels get. The most valuable thing to build in Global South power may not be a power plant at all. It is a utility that can pay its bills.
This is the deferred deep-dive from The Cost-of-Capital Gap (G10): the offtaker risk that dominates the base rate, examined on its own terms. It is the solvency node of the loop opened in Distribution Losses (G5), and it explains the premium on the bypass route in The Captive-Power Precedent (G4). The tariff politics connect to Transition Incidence — the same visibility that makes cost-reflective pricing hard.
The offtaker is the constraint. Across the Global South the utility that buys the power cannot fully collect for it — through losses, political tariffs, and late subsidy — so it cannot reliably pay the generators, and the unpaid obligation circulates as discom debt in India, circular debt in Pakistan, outstanding dues in Iran. That insolvency is the largest single input to the cost of capital and the solvency node of the distribution-loss loop. Fix the payment chain — meter, collect, guarantee, price to cost — and the financing follows. Leave it broken, and the cheapest panels in the world stay unbuilt.
No lord will lend to build upon a shore / where coin, once spent, will not come home again; / mend first the road by which the payment runs, / and gold will follow where it would not then.
