A market mechanism for Southeast Asia's energy transition
Southeast Asia's coal plants are locked in by contracts, not by economics. SPARC converts those contracts into tradable entitlements that renewable generators can acquire and redeem, without a single plant closure, billion-dollar buyout, or broken agreement.

The problem
Long-term power purchase agreements guarantee coal plants the right to supply electricity and be paid for it. Even where renewable energy is cheaper, contracted coal output must still be honored. Adding renewable capacity on top does not displace coal. It just adds cost.
Current coal phase-out models require a full buyout of the PPA: large upfront capital, years of preparation, and concentrated losses on the coal operator's balance sheet. SPARC offers a different path.

How SPARC works
A SPARC (Right to Supply Power And emit Carbon) is a tradable one-MWh unit that bundles three regulatory rights: the right to supply power, to receive the PPA payment, and to emit the associated carbon. Renewable generators acquire and redeem SPARCs. Each redemption shifts one MWh from coal to clean. Coal load factors decline. Contracts stay intact.
01
Fractionalize
An existing coal PPA is converted into a stream of discrete one-MWh SPARC units, each carrying the full contractual value of that MWh including energy and allocated capacity payments. The PPA remains legally intact. No debt restructuring. No regulatory pandora's box.
Registry issuance via I-TRACK02
Trade
A renewable operator acquires SPARCs from the coal plant operator at a negotiated price. The coal operator avoids fuel cost, sheds delivery risk, and retains its margin. The renewable operator gains access to guaranteed offtake without winning a new contract.

Redeem
The renewable operator delivers the MWh. The SPARC is surrendered against metered delivery data. Where verified emissions fall below the coal baseline, the unused emission right becomes an ARC: a carbon credit anchored in displacement that already occurred.
Ex-post carbon credit issuanceWho it's for
For coal-fired power plant operators
Your PPA guarantees revenue. SPARC lets you keep that guarantee while offloading the cost of generation: fuel, cycling stress, operating expenditure, and delivery risk. A renewable operator takes on the physical obligation. You receive a negotiated transfer price. Your PPA stays intact. Your capacity stays available for grid reliability.
The financial logic is simple. Where the transfer price plus avoided operating costs equals or exceeds what you would have earned by generating the MWh yourself, you are economically indifferent or better off. You control the pace. Start small, scale when it makes sense.
For renewable energy operators
Market access is the barrier, not economics. In most Southeast Asian grids, long-term coal PPAs occupy the available dispatch capacity. Winning new contracts requires years of auctions and regulatory process.
SPARC is a different route. By acquiring production rights from existing PPA holders, you gain access to guaranteed offtake. The production slot already exists. SPARC transfers the right and obligation to deliver it. Revenue comes from two sources: the PPA contract value on verified delivery, and an ARC carbon credit for every MWh where your emissions fall below the coal baseline.
For regulators
Your grid is contractually full. NDC commitments require measurable emission reductions, but forcing early retirement triggers compensation claims, legal disputes, and energy security concerns.
SPARC resolves this without requiring you to break a single contract. Coal plants remain on the grid. Contracts stay legally intact. Actual generation progressively shifts to lower-cost renewable operators through voluntary market transactions. Dispatch changes. Contracts don't. Because renewable generation is cheaper than the coal variable cost it replaces, consumer tariffs stay flat or fall.
For energy ministries
Long-term PPAs fix generation entitlements for decades. Even where renewable energy is cheaper, contracted coal output must still be honored. SPARC gives ministries a decarbonization tool that operates within the existing contractual architecture rather than against it.
The PPA remains legally intact. Capacity availability remains unchanged. The delivery obligation for a defined stream of MWh shifts to eligible lower-emission generators through direct agreements between parties. Coal operators participate because they retain their margin while reducing cost and risk. No upfront government capital required.
For philanthropists and impact investors
Current transition finance pays for the possibility of coal reduction, often years before any emissions are avoided. Deals take three to five years to structure, require large upfront capital, and deliver carbon credits against modeled projections.
SPARC flips the sequence. ARCs, Avoided Rights to emit Carbon, are issued only after a specific MWh of renewable generation has been dispatched and metered, and only to the extent that actual emissions fell below the coal baseline the plant had a legal right to produce. You are buying evidence of displacement. Not a promise that coal will eventually stop.
What is an ARC?
Each SPARC unit embeds the coal plant's regulated right to emit a defined quantity of CO₂ per MWh. When a renewable generator redeems the SPARC and delivers that MWh instead, the emission right goes unused.
The difference between what the coal plant was authorized to emit and what was actually emitted becomes a verified carbon credit. ARCs are issued ex-post, against metered delivery data. Not against a model of what might happen.
ARC calculation
No ARC can be created without a Redeemed SPARC. No Redeemed SPARC without verified metered dispatch. Integrity is embedded in the mechanism, not asserted afterward.
Where we are
SPARC is a draft concept under structured engagement with operators, regulators, and institutional stakeholders across Southeast Asia. We are not attached to any specific formulation on structure, regulatory pathway, or economic logic. We welcome challenge and practical pushback.
