Natural Gas STAR Program

National Grid Methane Challenge Partner Profile

Natural Gas STAR Partner Since 1994 | Methane Challenge Partner Since 2016

National GridExit has committed to apply best management practices (BMPs) across its operations to mitigate methane emissions from the emission sources listed below.

Learn more about National Grid's progress towards meeting its commitments to implement methane-reducing technologies and practices related to these emission sources:

At the bottom of this page, you will also find the methane reductions that National Grid has achieved in the program.

Background Information: Information submitted by National Grid, including its full dataset, can be found on its document page. This page includes the following documents:

  • Methane Challenge Implementation Plan
  • Historical Actions Fact Sheet (this fact sheet was developed by the company and represents the company's historic efforts to voluntarily reduce methane emissions before joining the Methane Challenge Program)
  • Methane Challenge Reported Data (BMP and ONE Future)

ONE Future Commitment Option

National Grid is also a member of the ONE Future Coalition and made a Methane Challenge ONE Future commitment. As a member of this Methane Challenge commitment option, National Grid reports additional detailed data on methane emissions and voluntary methane reductions across its operations to Methane Challenge annually. This ONE Future commitment option dataset is available on National Grid's document page.

ONE Future will use this ONE Future commitment option dataset to assess National Grid's progress towards its emissions intensity target. Please visit the the ONE Future Coalition's websiteEXIT for more information on the emission intensity targets and calculations.


Distribution

Mains - Cast Iron and Unprotected Steel

2017 3.82352688578373 -1
2018 4.75286284350413 -1
Commitment Details Company Selection
Segment: Distribution
Target Year: 2016
Target Replacement Rate: 1.5%
Current Replacement Rate: 4.75%

Graph shows:  The blue bars show National Grid’s annual cast iron and unprotected steel mains replacement rate. The green star indicates its 2016 target annual replacement rate (1.5%). National Grid has implemented this commitment by replacing cast iron and unprotected steel mains with plastic mains, reconditioning cast iron mains with plastic pipe inserts, and replacing unprotected steel with protected steel.

Year Replacement Rate (%)
2017 5.09746942729144
2018 1.99040749608961
Commitment Details Company Selection
Segment: Distribution
Target Year: 2016
Current Replacement Rate: 1.99%

Graph shows:  The blue bars show National Grid’s annual cast iron and unprotected steel services replacement rate. When committing to this source, partners commit to replace services when replacing the main; partners do not set a target replacement rate for services. National Grid has implemented this commitment by replacing cast iron and unprotected steel services with plastic.

Methane Reductions

 
Year Methane Reductions (MTCO2eq)
2017 48278.2803125
2018 43856.181735
2019 0
2020 0

Since joining the Methane Challenge program, National Grid 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: 3,685 metric tons
  • Reductions in carbon dioxide equivalents: 92,134 metric tons
  • Natural gas savings: $575,840*

*Natural gas savings assumes a natural gas price of $3.00 per thousand cubic feet, based on the average of daily Henry Hub Natural Gas Spot Prices in 2018, rounded to the nearest dollar

Methane Challenge Program LogoAbout 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 Fact Sheet.

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).
Learn more about the BMP Commitment.

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.
