CMS Energy Corporation - Water Security 2022

W0. Introduction

W0.1

(W0.1) Give a general description of and introduction to your organization.

CMS Energy Corporation (CMS Energy) is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including its principal subsidiary, Consumers Energy Company (Consumers Energy or Company), an electric and natural gas utility and CMS Enterprises Company (CMS Enterprises), primarily a domestic independent power producer and marketer. Consumers Energy's electric utility operations include the generation, purchase, distribution, and sale of electricity, and its gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers Energy serves about 6.8 million of Michigan's 10 million residents. CMS Enterprises, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation and marketing of independent power production. CMS Energy was also the parent holding company of EnerBank USA® (EnerBank) until October 1, 2021 when EnerBank was acquired by Regions Bank. This report is ONLY for the principal subsidiary of CMS Energy, Consumers Energy.

Consumers Energy acknowledges that the long-term sustainability of our Company depends upon our ability to listen to our stakeholders and conduct business that promotes environmental health, increases societal value, and brings economic success so that we can provide safe, reliable, and affordable energy to our customers. This commitment is advanced by our focus on the triple bottom line: people, planet and prosperity.

In 2018, Consumers Energy committed to a set of Corporate Planet Breakthrough Goal to save 1 billion gallons of water through 2022.

Rationale for this coverage

The Company is developing procedures to request and document information from its largest suppliers, on a cost basis, to discern if the supplier has the potential to negatively impact the environment, if an environmental management system has been implemented and whether cost effective measures to avoid pollution have been implemented. In addition, the Company tracks environmental regulations and rulemakings to ensure compliance with emerging contaminants.

Impact of the engagement and measures of success

Supplier surveys on environmental management and water-related metrics allow the Company to evaluate supplier performance in key sustainability areas and provides context for pursuing further engagement with suppliers in these areas.
