The Role of Load Letters in Gas Conversions
When the decision is made to transition a building from an oil-burning boiler to one powered by natural gas, one of the initial steps in the project involves completing and submitting a gas “Load Letter” to Con Edison. This document can be sent by authorized personnel for the building or representatives such as engineers or contractors working on the building’s behalf.
Components of a Load Letter
A Load Letter contains the following information:
- A list and description of the existing gas-burning equipment in the building
- The associated gas loads for each piece of equipment
- Details of the proposed new equipment to be installed
- The associated gas loads for the new equipment
Con Edison’s Review and Gas Service Evaluation
Once submitted, the Load Letter is reviewed by Con Edison’s Engineering department. This team uses the information provided in the Load Letter to assess if the building’s existing gas service is sufficient or if it needs an upgrade to accommodate the increased projected gas loads.
Upon completion of Con Edison’s review, a gas ruling and service layout are sent to the customer, contractor, or the contact person listed on the Load Letter. With this information, the building can proceed with their gas conversion project.
