Selling Your Tier II AECs: Broker vs. Aggregator vs. Going Direct

You have a qualifying efficiency project and verified savings — now how do you actually turn those Tier II AECs into cash? There are three broad paths: sell direct, work with a broker, or use an aggregator. Each suits a different size and sophistication of project, and choosing the wrong one can cost you in price, in time, or in credits that never make it to market. This guide walks through how each option works and who it fits.

First, Understand What Selling Actually Involves

Before comparing paths, it helps to know what the work consists of. Turning savings into sold credits means confirming your project's eligibility, completing measurement and verification, registering and certifying the credits in PJM-GATS, finding a buyer, negotiating a price, and executing the transaction within the credit's useful vintage. The three selling paths differ mainly in how much of that workload you keep versus hand off — and in how much of the proceeds you retain in exchange.

Going Direct

Selling direct means you do it all yourself: register your own project in GATS, manage measurement and verification, find buyers, and negotiate sales. The appeal is that you avoid sharing any proceeds with an intermediary. The tradeoff is significant. You take on the registration, certification, compliance, and market-timing work, and you need enough internal energy and administrative expertise to do it well. Just as important, a single small project often lacks the volume to attract competitive buyers — large purchasers may not want to transact for a modest number of credits, leaving a direct seller with weak pricing or no buyer at all. Going direct tends to make sense only for large, sophisticated owners with the staff and volume to justify it.

Using a Broker

A broker acts as an intermediary who connects you with buyers and helps execute a sale, typically in exchange for a commission or a spread on the transaction. You retain ownership of your credits and remain responsible for getting them registered and verified, but you gain access to the broker's buyer relationships and read on the market. This path suits owners who are comfortable handling their own registration and compliance work but want help finding a buyer and securing a good price. The broker's value is in distribution and market knowledge; the limitation is that you are still carrying the upstream burden of producing sellable, certified credits on your own.

Using an Aggregator

An aggregator takes a more end-to-end role. It bundles credits from many projects — including small ones that could never reach the market alone — into a larger, more marketable position, and typically manages the registration, verification, GATS tracking, and the sale itself. For the owner, this is the path of least friction: you hand off the complexity and receive your share of the proceeds. The pooling matters more than it might seem. By combining many owners' credits, an aggregator reaches a transaction size that attracts serious buyers and competitive pricing that an individual small project simply cannot command on its own.

Matching the Path to Your Project

The right choice follows from an honest look at your volume and your internal capacity. Large owners with internal energy teams and substantial credit volume may reasonably go direct and keep all the proceeds. Owners who can manage their own compliance but want help selling may prefer a broker. The majority of commercial owners, however, have one or a few projects, modest credit volume, and no desire to become AEC experts — and for them an aggregator that handles the full lifecycle and pools their credits for stronger market access is usually the best fit. The question to ask yourself is simple: how much of the registration, verification, and market work do I actually want to own?

Beware the False Economy

It is tempting to look only at intermediary fees and conclude that going direct is cheapest. But the lowest fee is not the same as the highest net proceeds. A small project sold direct may fetch a weaker price, or miss its vintage window entirely while the owner learns the registration process, wiping out any savings on commission. The right comparison is net value in your pocket after the credits are sold within their useful life — not the headline fee. For many owners, paying for expertise and market access yields more than going it alone.

A Practical Way to Decide

Start by estimating your annual credit volume and honestly assessing your team's bandwidth and familiarity with GATS and AEPS rules. High volume plus deep expertise points toward direct. Moderate capability with a desire for help selling points toward a broker. Limited volume or limited expertise — the situation most commercial owners are in — points toward an aggregator. Then weigh the net proceeds, not just the fees, and factor in the real risk of credits stranding if the process drags.

There is no single right answer, only the right fit for your volume and capacity. Be honest about how much of the registration, verification, and market work you want to own, compare net value rather than headline fees, and pick the path that gets your verified savings to market at the best realistic outcome.
