Branchville Oil Company Transitions to B10 Bioheat® Fuel

As of July 1, Branchville Oil Company has increased the biofuel blend in our heating oil from 5% (B5) to 10% (B10). This change follows new state requirements in Connecticut and New York, where all heating oil must now include at least 10% biofuel.

What This Means for You

No stress, no changes — your current heating system is already compatible with Bioheat® fuel. That means you can keep the comfort you’re used to while enjoying the benefits of cleaner, greener energy.

By moving to B10, Branchville Oil Company customers are helping cut emissions and reduce the use of millions of gallons of traditional heating oil each year. The impact? Cleaner air for our communities and the carbon-reduction equivalent of making more than 100,000 homes carbon neutral.

Why Bioheat® Fuel Matters

Bioheat® fuel blends ultra-low sulfur heating oil with renewable biofuel made from resources like soybean oil, inedible corn oil, and recycled cooking oil. By putting these surplus feedstocks to work, Bioheat® reduces greenhouse gas emissions by at least 50% compared to petroleum diesel.

Higher blends mean even greater benefits. The industry is on track to steadily increase levels — with Connecticut set to reach B15 by 2030, B20 by 2034, and B50 by 2035 — all working toward a net-zero carbon future by 2050.

The Bottom Line

Upgrading from B5 to B10 is more than a state requirement — it’s a big step toward a cleaner energy future. At Branchville Oil Company, we’re committed to meeting these new standards while continuing to deliver the reliable service and comfort you count on.

By choosing Bioheat® fuel, you’re not just heating your home — you’re helping create a healthier environment for generations to come.
