Why nobody can prove flexibility actually happened

A flexibility company tells a data center to reduce its power. The data center reduces. The flexibility company reports to the grid operator: we cut 25 megawatts for three hours.

The grid operator asks: prove it.

The flexibility company cannot credibly prove it because the flexibility company is the entity that orchestrated the reduction. It has every incentive to overstate the result. The grid operator needs someone independent to confirm. This is not a hypothetical objection. It is the structural reason a grid operator will not grant cheaper, faster, conditional-firm interconnection on the strength of a flexibility commitment alone.

An auditor problem, not a sensor problem

Most of the discussion about measurement and verification (M&V) focuses on the meters: are the readings clean, are the timestamps right, is the data tamper-evident at the hardware level. These matter. But they are necessary, not sufficient.

The deeper problem is the same one that financial accounting solved with external auditors a century ago. A company knows its own numbers. Investors do not trust the company to report them honestly. So the accounting profession exists, audit standards exist, and external firms attest to numbers they have no incentive to inflate.

Energy flexibility has the same gap. The technology to do the reduction is solved. The independent attestation that the reduction was real, that it counted toward capacity, that it was worth the payment grid operators eventually owe. That does not exist yet as a standalone, neutral product.

The fragmentation tax

It also has to work across markets. PJM uses a high-4-of-5 baseline. CAISO uses 10-in-10. ERCOT will use whatever the SB6 rulemaking produces in late 2026. RTE in France runs aFRR and mFRR with their own methodology. German TSOs balance through regelleistung.net. National Grid in the UK has flexibility services. Each market is a different settlement engine, a different baseline math, a different reporting format.

Anyone who wants to monetize flexibility across more than one of these has to reinvent compliance in each. That is a tax on the people doing the actual work, and it is exactly the kind of tax a thoughtful piece of infrastructure can eliminate.
