Eastern Gas Transmission and Storage Methane Challenge Partner Profile
Natural Gas STAR Partner (2011 - 2022) | Methane Challenge Partner (2016 - 2024)
In 2020, Berkshire Hathaway Energy acquired a number of Dominion Energy gas transmission, storage, and LNG assets. These assets are operated by Berkshire Hathaway Energy GT&S, a standalone subsidiary of Berkshire Hathaway Energy. The Methane Challenge Partner formerly known as Dominion Energy Transmission, Inc. is now known as Eastern Gas Transmission and Storage.
Eastern Gas Transmission and Storage has committed to apply best management practices (BMPs) across its operations to mitigate methane emissions from the emission source listed below.

At the bottom of this page, you will also find the methane reductions that Eastern Gas Transmission and Storage has achieved in the program.
Methane Challenge Data: Data submitted by Eastern Gas Transmission and Storage can be found in the Methane Challenge BMP Dataset at the bottom of this page.

| Year | Reduction Rate (%) | Commitment 1 Target Rate and Year | Commitment 2 Target Rate and Year |
|---|---|---|---|
| 2016 | 54.84 | -1 | -1 |
| 2017 | 57.22 | -1 | -1 |
| 2018 | 62.68 | -1 | -1 |

| 2021 | 75.18 | 50 | -1 |
| 2022 | 85.4 | -1 | 60 |
| Commitment Details | Company Selection |
|---|---|
| Segment: | Transmission and Storage |
| Target Year: | 2022* |
| Target Reduction Rate: | 60% |
| Current Reduction Rate: | 85.4% |
Graph shows: The blue bars show the percent of potential emissions from planned blowdowns that Eastern Gas Transmission and Storage reduced through implementation of best management practices each year. The black star indicates its 2021 target annual rate (50%). Eastern Gas Transmission and Storage has implemented this commitment by routing gas to low-pressure systems and utilizing hot taps. Eastern Gas Transmission and Storage extended/updated the company’s annual commitment through 2027. However, because EPA ended the Methane Challenge Partnership and will no longer collect data for 2023 or future years, the green star is used to represent the target annual replacement rate (60%) on 2022, the final reporting year.
Methane Reductions
| Year | Methane Reductions (MTCO2eq) |
|---|---|
| 2016 | 134027.04 |
| 2017 | 166891.48 |
| 2018 | 153188 |
| 2019 | 108370.08 |
| 2020 | 106734.6 |
| 2021 | 189456.68 |
| 2022 | 91337.96 |
Since joining the Methane Challenge program, Eastern Gas Transmission and Storage has achieved the following methane emissions reductions, which are also expressed in terms of carbon dioxide equivalents and the value of the amount of natural gas saved:
- Methane emissions reductions: 33,929 metric tons
- Reductions in carbon dioxide equivalents: 950,006 metric tons
- Natural gas savings: $12,369,868*
*Natural gas savings assumes a natural gas price of $7.00 per thousand cubic feet, based on the average of daily Henry Hub Natural Gas Spot Prices in 2022, rounded to the nearest dollar

Methane Challenge Accomplishments Calculation Methods
This document describes how EPA analyzes Partner-submitted data to calculate Methane Challenge program ‘accomplishments’; specifically, the partner commitment progress metrics shown on each Partner Profile webpage as well as Methane Challenge program-level methane reductions.
Methane Challenge Accomplishments Calculation Methods (pdf)
This document does not describe how Methane Challenge Partners calculate the data they report to EPA. Those calculation methods are detailed in the Methane Challenge Technical Documents.
Pursuant to 5 CFR § 2635.702(c)(2), names are displayed here as the result of recognition for achievement given under an agency program of recognition for accomplishment in support of the agency’s mission. Any reference to a specific company or commercial product or service by trade name, trademark, manufacturer, company, or otherwise does not constitute or imply the endorsement or recommendation of EPA.
About the Methane Challenge Program
The Methane Challenge Program provides a new mechanism through which U.S. oil and gas companies can make more specific and transparent commitments to reducing methane emissions. Partner companies choose between two commitment options to cost-effectively reduce methane emissions. For background information on the Methane Challenge program, please check out the Methane Challenge Program Fact Sheet (pdf) .
Best Management Practice (BMP) Commitment
The BMP Commitment is intended to spur near-term, widespread implementation of methane mitigation activities across the oil and natural gas value chain to address methane emissions from key emitting sources. By committing to address an emission source, the partner is committing to implement a BMP on all such sources in their operations. Progress towards a commitment is generally indicated by the percent of sources to which the partner has implemented a BMP as part of the Methane Challenge. Commitments for a few sources are instead based on achieving a target rate (of equipment replacement or methane emission reductions).

ONE Future Emissions Intensity Commitment
The ONE Future Commitment is intended to drive action to achieve segment-specific intensity targets, established through the ONE Future Partnership, which will represent emissions per volume produced or volume of throughput and add up to a 1% or less “leakage rate” along the natural gas value chain by 2025.
