Exelon's climate arm backs the vendor it will deploy

Exelon's climate investment arm has backed Continuum, the grid-planning software firm that has been building its Optioneer platform since 2018, and the deployment riding along with the equity is the more consequential half of the arrangement. Optioneer is to be rolled out across Exelon's utility companies, which operate in the PJM interconnection transmission region across five states and the District of Columbia, according to a Sept. 16 company blog; ESG Dive first reported the investment.

The coverage gives no check size, valuation, or ownership stake, which leaves the reasoning to carry the story. Davis, who leads Exelon's Climate Change Investment Initiative, told ESG Dive that transmission planning is where the utility wants to speed the process as load demand rises, part of a wider focus on affordability and efficiency in how it builds and runs infrastructure. Continuum and 2c2i first connected in December 2025, putting roughly nine months between first contact and the rollout announcement — a cadence that reads like a procurement calendar as much as a venture one.

Continuum says its platform has screened more than 420,000 miles of infrastructure alternatives in pursuit of lower-impact, faster-to-permit routes, and chief executive Grzegorz Marecki framed the pitch in Exelon's release as giving utilities and developers a repeatable approach to planning and delivering infrastructure predictably as electricity demand climbs. The fund's own scorecard, from Exelon's August sustainability report, counts more than $555 million in follow-on funding raised by cohort companies, more than $3,558 jobs created, more than $548 million in revenue, and 1.2 million metric tons of carbon dioxide avoided or removed. Exelon added sustainable energy and grid solution companies Public Grid and Backstop to the cohort last month.

This is corporate venture capital in which the investor is also the customer, a structure that does more for a software vendor's reference list than for its cap table. A load-serving utility that installs a planning tool across five states and the District of Columbia hands that vendor the one thing venture money cannot buy: a production account inside a utility, with a liaison assigned to help it scale. Whatever return Exelon books on the position is secondary to the time it buys on its own transmission planning work, and the two are difficult to separate on a single line of an investment memo.

As this publication has argued, transition supply chains get financed when someone absorbs early-stage risk that generalist capital will not price, and the facts here cut sideways against the sequence we have described: the capital is a private utility balance sheet moving before any public program has touched grid-planning software, and it moves because the buyer and the backer are the same entity, which means the pricing question — what a mile of avoided planning delay is worth — gets answered internally rather than by a market. The model, as a result, likely stays available to utilities and largely closed to funds that would have to underwrite the same software on a standalone return.

Watch whether the pattern repeats with Public Grid and Backstop: if stakes there are paired with deployments the way this one is, Exelon has assembled a procurement channel with an investment attached, and the vendors selling planning and grid software into utilities will find themselves bidding against the utility's own balance sheet.
