DMIᵀᴹ Index for Gas Utilities

April 11, 2022


Gas Utilities have a DMIᵀᴹ Index in the range of 1.80% to 2.55% with an average of 2.18%. The DMI Index for these companies is based on the valuation of equipment data.

A higher DMI Index is generally preferable across companies and industries. By way of reference, internet companies have a higher DMI Index because most of their enterprise value is derived from data. For example, Google’s DMI Index is 93 percent.


  • DMI Index = Data Valuation / Enterprise Value
  • Data Valuation = Equipment Data Valuation
  • Enterprise Value =  Equity Value + Long Term Debt – Cash, a key metric used in the investment community


The YDC team recently published a DMI Index for major Gas Utilities in the United States. Here is an example for Northwest Natural Holding Company along with a benchmark that includes other companies in the industry.

The data valuation is based on research that indicates that accurate and timely equipment data can have a positive impact on predictive maintenance costs. The equipment data valuation for gas utilities is based on comparable companies and publicly-available data sources. The total value of data will likely be higher once additional datasets relating to product, employees, and real estate are included.
