Not all carbon credits make sense
Ours do

BESS carbon credits that improve
affordability and protect the environment.

A carbon payment makes more battery operations more valuable. With greater remuneration, battery energy storage system (BESS) operations displace expensive thermal generation, so power gets cleaner and more affordable.

Powering today. Protecting tomorrow.

About Rational Carbon

We built Rational Carbon because clean power should not cost more. Most programs pay operators to depart from market-optimal dispatch. That raises prices for everyone and mostly benefits the thermal generators storage is meant to displace. We take the opposite approach. We credit batteries for the emissions impact of rational operation.

Cleaner and cheaper. Measured, not assumed.

The Rational Carbon methodology

Additionality, without distorting the market.

A carbon payment makes BESS more competitive, thus displacing more thermal generation. No one has to bid away from the market to earn the credit.

Additionality, measured

Every credit discloses how much of the outcome was incremental.

Confirmable

Emissions are matched to each interval at the finest location the market publishes. Every credit carries its inputs with it, so the numbers can be rerun.

Sellers

Turn the dispatch you already run into credit revenue.

You keep dispatching the way the market tells you to. We pay you to run more cycles, which lowers prices and cuts emissions, and every cycle becomes a credit you can sell.

1No change to dispatch

Keep bidding to the market. Nothing to withhold or shift, and nothing to explain to ratepayers or regulators.

2Paid for past and future cycles

New and existing batteries qualify. We can compensate reductions from the last 3 years, and we pay for the extra cycles incented by Rational Carbon.

3A number you can check

Every credit is matched to your location, interval by interval, with each input disclosed, so your stakeholders and counsel can review it.

Buyers

Know exactly what you are buying.

Every credit comes with its evidence. You see how much of the outcome was incremental, what was measured, and what was estimated.

1Disclosed additionality

Each credit states the share that is additional.

2No market distortion

Dispatch stays market-optimal, so there is no chasing carbon over dispatch value.

3Interval-level matching

Emissions are tied to each interval at the finest location the market publishes, not a flat rate.

4Reproducible inputs

Every input is sourced and travels with the credit, so your counsel, auditors, or a third party can rerun the numbers.

5Standards-based verification

Verified, insured and tracked from issuance through retirement managed by our partner 1089 (www.1089inc.com).

6Aligned by design

We earn a share of the credits we generate, so our incentive is delivery. Verification, insurance and tracking sit with our partner 1089, and every input is disclosed so you can check our work.
