This is the Congressional Budget Office Cost Estimate as ordered reported by the House Committee on Energy and Commerce on June 10, 2021. From the Document: "H.R. 2928 would direct the Department of Energy (DOE) to establish a voluntary program to test the cybersecurity of products and technologies intended for use in the nation's bulk power system. The bulk power system comprises the facilities and control systems necessary for operating an interconnected energy transmission network and the electric energy needed from generation facilities to maintain transmission system reliability. DOE tests the cybersecurity of bulk power systems through its Cybersecurity Testing for Industrial Control Systems program. Because H.R. 2928 would codify the department's current practices, implementing the bill would not affect the federal budget. H.R. 2928 would impose an intergovernmental mandate, as defined in the Unfunded Mandates Reform Act (UMRA), on state, local, and tribal governments. The bill would preempt state and local laws that could otherwise cause governmental agencies participating in the Cyber Sense program to disclose information about their activities, such as the sharing of cybersecurity information. Although the preemption would limit the application of state and local laws, CBO [Congressional Budget Office] estimates that it would impose no duty on state or local governments that would result in additional spending or a loss of revenues."
