The recent recognition of United States Environmental Protection Agency (EPA) shows how Marathon Petroleum the commitment to energy efficiency does not stop at its operational strengths. Five refineries and the company San Antonio The office building earned the agency’s 2021 ENERGY STAR certifications for achieving energy efficiency levels that rank in the top 25% of similar facilities across the country.

Refining’s focus on energy

The EPA uses the Energy Intensity Index from benchmarking firm Solomon to compare a refinery’s efficiency performance to the performance of similar industrial facilities nationwide. This generates an ENERGY STAR score on a scale of 1 to 100, and facilities must achieve a score of 75 or higher to receive ENERGY STAR certification. Our refineries that ranked in the first quartile in 2021 are:

Anacortes, Washington – second consecutive and second overall certification

Canton, Ohio – 16th consecutive certification (each year the refineries were eligible)

Garyville, Louisiana – 16th consecutive certification (each year the refineries were eligible)

Robinson, Ill. – fourth consecutive certification and seventh overall

St. Paul’s Park, Minnesota – third consecutive certification and fourth overall

These same refineries also achieved certifications last year when Marathon Oil became the first oil refiner to have five refineries earning certifications in one year. Since the start of the ENERGY STAR program, our refineries have achieved more certifications than all other refiners combined.

A key driver of these achievements is the refining organization’s Focus on Energy (FOE) program, which establishes key performance indicators to guide energy management at all sites. In the third quarter of 2021 alone, FOE initiatives helped avoid more than 125,000 metric tons of carbon dioxide equivalent emissions and reduce energy costs by $6 million.

Retention of office

ENERGY STAR certification for the 659,000 square feet San Antonio office complex was its first certification since 2018 and its fifth overall. To be certified, commercial buildings must achieve an ENERGY STAR score of 75 or higher, based on their energy consumption calculated with the ENERGY STAR Portfolio Manager tool. The score takes into account differences in operating conditions, regional weather data and other considerations. The information in the certification application must also be verified by a licensed professional engineer or licensed architect to be eligible for approval.

The EPA launched the ENERGY STAR program in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency. Refineries were first eligible for certification in 2006. The first ENERGY STAR label awards for commercial office buildings were in 1999.
