Public utilities: rates; separate rate class for large-load customers; require. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10ii.

Maddy summarySB 1047 creates a new rate class for large energy users, specifically targeting data centers, to ensure they do not shift costs to residential and small business customers. The bill requires these facilities to sign long-term contracts with electric utilities that include a minimum monthly charge based on their potential usage, even if they consume less power. Additionally, the legislation mandates that large energy users pay for all costs they cause, such as new power lines and generation, and must provide collateral or a letter of credit to guarantee these payments. To further protect the grid, the bill also requires these facilities to participate in demand response programs, source 90% of their electricity from clean energy, and pay a significant application fee.

Businesses: other; Michigan zoning enabling act; make subject to the data center community benefit act. Amends sec. 205 of 2006 PA 110 (MCL 125.3205). TIE BAR WITH: SB 1050'26

Maddy summarySB 1051 amends the Michigan Zoning Enabling Act to explicitly include the Data Center Community Benefit Act as a governing standard for local zoning ordinances, ensuring that zoning decisions for data centers must comply with community benefit requirements. The bill also clarifies that counties and townships cannot regulate the drilling or operation of oil and gas wells, while modifying rules for mining valuable natural resources by placing the initial burden of proof on those challenging a zoning decision. Additionally, it protects renewable energy projects that received special land use approval after January 1, 2021, from having their approvals revoked if substantial construction or specific financial expenditures have occurred. This legislation is tied to SB 1050, meaning it will only take effect if that companion bill is also enacted into law.

Businesses: other; community benefit agreements; require certain data centers to be subject to. Creates new act.

Maddy summaryThis bill requires data centers in Michigan to sign community benefit agreements before they can begin construction or operation. These agreements are legal contracts between the data center owner or operator and local governments or community stakeholders that mandate the provision of specific resources to benefit the local area. Local governments must review and approve these agreements within 90 days, and they can deny necessary permits if such an agreement has not been finalized. The legislation aims to ensure that data center projects provide tangible benefits to public health, safety, and general welfare in the communities where they are built.

Water supply: conservation; permit for water used for consumptive use purposes; provide for. Amends secs. 32705, 32708a, 32713 & 32723 of 1994 PA 451 (MCL 324.32705 et seq.) & adds sec. 32723a.

Maddy summaryThis bill updates Michigan's water laws to streamline the registration process for large-scale water withdrawals while introducing new requirements for water conservation and reporting. It primarily affects property owners, agricultural operators, and industrial facilities that plan to extract significant amounts of water, requiring them to register their intended capacity before beginning operations. The legislation mandates that the state develop and post generic water conservation measures for different sectors, with specific rules for agriculture and data centers, and requires facilities permitted under new provisions to submit annual reports on wastewater usage and pollutant levels. Additionally, the bill clarifies exemptions for smaller residential wells and test wells, while establishing a timeline for property owners to develop their water capacity after registration or face invalidation of their application.

Public utilities: electric utilities; project labor agreements and prevailing wage and fringe benefit rates; require for certain data center contracts. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10ii.

Maddy summaryThis bill requires electric utilities in Michigan to include specific labor conditions in contracts for building or maintaining data centers. Under the new rules, these projects must use registered apprenticeship programs, pay workers at least the prevailing local wage and fringe benefit rates, and utilize project labor agreements or collective bargaining agreements. The legislation defines data centers as facilities housing equipment for data storage and processing and aims to ensure fair labor standards for construction work without speculating on future economic impacts.

Public employees and officers: other; certain nondisclosure agreements; prohibit. Creates new act.

Maddy summaryThis bill, known as the Data Center Nondisclosure Agreement Prohibition Act, prevents public employees and officers in Michigan from signing nondisclosure agreements related to data center projects. It defines a data center as a facility with significant power demand and restricts these officials from using confidentiality claims to hide information from the public. The law applies to agreements entered into, amended, or renewed after its effective date, though it allows exceptions for legally privileged information or settlement documents. Violations of this rule could result in a civil fine of up to $1,000, which can be pursued by county prosecutors or the attorney general.

Housing: landlord and tenants; limitations on fees charged to tenants; provide for. Amends sec. 3 of 1978 PA 454 (MCL 554.633).

Maddy summarySB 373 prohibits landlords from charging tenants extra fees for using specific payment methods (like credit cards or checks) in rental agreements. It requires leases to include at least one payment option without additional charges. The bill directly affects tenants by preventing unfair fees and landlords by restricting lease terms. Key provisions ban clauses that waive tenant rights related to security deposits, habitability, or discrimination, and require written notice for certain rent increases. This amendment to Michigan's Truth in Renting Act (MCL 554.633) focuses on making rental agreements fairer through concrete, enforceable limits on fees and unfair terms.

Education: teachers and administrators; interim teaching certification process; modify. Amends sec. 1531i of 1976 PA 451 (MCL 380.1531i).

Maddy summaryThis bill modifies Michigan's interim teaching certification process to establish stricter requirements for individuals seeking to teach without a full teaching certificate. It mandates that all candidates complete an approved alternative program with intensive training equivalent to at least 12 college credits, including coursework in child development, diverse learners, and classroom experience. A significant change is the prohibition of new interim certificates for special education teaching starting July 21, 2027, which requires applicants to complete an additional 32-credit specialized training program unless they already hold a full teaching certificate. The legislation also ensures that teachers holding these interim certificates receive intensive observation and coaching while they work toward earning a permanent Michigan teaching certificate.

State finance: authorities; use of grant funds and issuance of revenue bonds; modify. Amends title & secs. 2, 8, 9, 10, 13, 14, 14a, 16, 18, 20, 23, 24 & 25 of 1978 PA 639 (MCL 120.102 et seq.) & adds sec. 19a.

Maddy summarySB 52 amends Michigan's Port Authority Act (1978 PA 639) to update financial rules for port authorities. It modifies how these authorities manage grant funds, issue revenue bonds, and use "ancillary financing facilities" like interest rate swaps or insurance contracts. The bill adds new language (Section 19a) and revises multiple existing sections to clarify financial operations. This procedural update directly affects port authorities managing state-owned port facilities, such as piers, docks, and related infrastructure, without creating new facilities or changing their core responsibilities.

Insurance: health insurers; methods of payments and reimbursements for dental benefits; provide for. Amends 1956 PA 218 (MCL 500.100 - 500.8302) by adding sec. 3406ss.

Maddy summarySB 105 requires health plans and nonprofit dental corporations providing dental benefits to offer payment methods that deliver 100% of the payable amount to dentists without charging the dentist a fee to access payment (excluding fees from the dentist's financial institution). Dentists who choose to opt out of a payment method must maintain that choice until they opt back in or sign a new contract. This bill directly affects dentists and dental benefit providers in Michigan, applying to policies delivered, issued, or renewed after the law's effective date. It mandates specific reimbursement structures to reduce financial barriers for dental providers.
