Tools & Methods

Created by a coalition of utilities, the Smart Grid Maturity Model (SGMM) is maintained by the Carnegie Mellon Software Engineering Institute (SEI) as a resource for utility industry transformation. Utilities can leverage this management tool to ensure that all aspects of transformation planning are considered, prioritize their options, and measure their progress as they move toward the realization of a smart grid.

SGMM Model
The core of the SGMM product suite is a model of smart grid maturity in an electric power utility. The model's 175 characteristics are organized into eight domains:

  • Strategy, Management, and Regulatory
  • Organization and Structure
  • Grid Operations
  • Work and Asset Management
  • Technology
  • Customer
  • Value Chain Integration
  • Societal and Environmental

Assessment of a utility's characteristics against the model provides a view of the utility's current state of smart grid maturity per domain, according to the model's maturity levels (shown in the following table). Utilities can use this information to generate inputs into their smart grid roadmapping, planning, and implementation process.

Maturity Level Name Maturity Characteristics
5 Pioneering Breaking new ground, industry-leading innovation
4 Optimizing Optimizing smart grid to benefit entire organization; may reach beyond organization; increased automation
3 Integrating Integrating smart grid deployments across the organization; realizing measurably imrproved performance
2 Enabling Investing based on clear strategy; implementing projects to enable smart grid (may be compartmentalized)
1 Initiating Taking the first steps, exploring options, conducting experiments, and developing a smart grid vision
0 Default Default level (status quo)

The SGMM Matrix offers a summary view of the model domains and expected characteristics in each domain and at each maturity level.

SGMM Compass Assessment Survey
Utilities use the SGMM Compass Assessment Survey to walk them through the SGMM and characterize the status of their smart grid implementations. Completing the survey and having it scored provides the utility with a maturity level for each domain in the model. In addition, each scoring report includes aggregate data from the other utilities that have completed the survey, which can be used for comparative analysis. 

SGMM Navigators can guide utility stakeholders through completing the survey and analyze the results. Utilities can also used the survey for self-assessment. (For self-assessment and scoring, please contact SEI Customer Relations.)

SGMM Navigation Process
The five-step SGMM Navigation process helps utility organizations chart a technical, organizational, and operational path through their grid modernization effort. During a Navigation, an SEI-certified SGMM Navigator helps the organization complete the Compass survey, analyzes the resulting data to provide the utility its smart grid maturity status against the SGMM, and leads utility stakeholders to consensus around aspirations for a planning horizon.

Electricity Subsector Cybersecurity Capability Maturity Model

The Electricity Subsector Cybersecurity Capability Maturity Model (ES-C2M2) was developed as part of a White House initiative to enhance the security and reliability of the nation's electrical grid. The initiative was led by the Department of Energy (DOE), in partnership with the Department of Homeland Security (DHS), and in collaboration with industry, private-sector, and public-sector experts—including a technologists from the SEI. The ES-C2M2can be downloaded on the Department of Energy website at
