    Equitable Energy Transition Planning in Holyoke Massachusetts: A Technical Analysis for Strategic Gas Decommissioning and Grid Resiliency
    (2023-01-01)
    This report provides a framework for targeting geographic areas for electrification and strategically managing leak-prone gas pipe infrastructure. Section I evaluates alternatives for gas pipeline replacement, as aging gas infrastructure is a widespread issue and requires modernization to minimize methane leaks which have significant health, safety, and climate implications. We consider scenarios including business as usual, accelerated strategic electrification, and options including propane tanks. This analysis finds that avoided pipeline replacement can reduce methane leaks from the distribution system; reducing greenhouse gas emissions; and lead to overall costs savings for consumers. Section II of this report demonstrates how different data sets can be integrated to better inform site selection of infrastructure projects. It demonstrates a framework for identifying targeted geographic areas to prioritize and opportunities for coordinated efforts. The report shows how identifying sites where the rehabilitation of aging sewer or water assets can be coordinated with undergrounding electric distribution lines and gas pipeline decommissioning can save on trenching and utility relocation costs. Such costs often make up a significant portion of any capital planning project. Prioritizing specific street segments for decommissioning allows for cities to plan more efficiently, increasing reliability and resiliency.
