Primary HB 3778
Passed · Texas House · Lead sponsor
Relating to the use of geothermal energy as a dispatchable generation resource.

Maddy summaryHB 3778 defines geothermal energy facilities as "dispatchable" under Texas law, meaning their power output can be controlled by human operators. This reclassification directly affects geothermal developers in the ERCOT grid region by making their facilities eligible for state financial incentives. The bill creates two key provisions: (1) loans for upgrading existing dispatchable facilities (minimum 100MW capacity increase) and (2) completion grants for new dispatchable facilities (minimum 100MW capacity), excluding electric storage facilities. These mechanisms aim to incentivize geothermal energy development as a reliable power source within Texas' energy grid.

Co-sponsor HJR 34
Passed · Texas House · Co-sponsor
Proposing a constitutional amendment to authorize the legislature to provide for an exemption from ad valorem taxation of the amount of the market value of real property located in a county that borders the United Mexican States that arises from the installation or construction on the property of border security infrastructure and related improvements.

Maddy summaryHJR 34 proposes a constitutional amendment to allow Texas lawmakers to create a property tax exemption for landowners in counties bordering Mexico. The exemption would apply specifically to the increased market value of real property resulting from border security infrastructure (like barriers or roads) and related improvements. If approved by voters in November 2025, this would let the legislature establish rules for qualifying properties and define "border security infrastructure." The change would directly affect property owners in border counties whose land value rises due to such projects. It does not exempt all property, only the value increase tied to border security construction.

Co-sponsor SB 1999
Passed · Texas Senate · Co-sponsor
Relating to protection for a public employee's or student's use of terms consistent with biological sex.

Maddy summarySB 1999 prohibits school districts, charter schools, colleges, and government employers from disciplining, retaliating against, or discriminating against employees or students who use terms consistent with a person's biological sex when addressing them. It applies to K-12 staff and students (Section 22.905), higher education staff and students (Section 51.9316), and public employees addressing colleagues or the public (Section 3001.001). The law specifically protects using terms matching a person’s sex assigned at birth, without requiring anyone to use such terms. The bill takes effect immediately if passed by two-thirds vote, or September 1, 2025, otherwise.

Primary HB 4273
Passed · Texas House · Lead sponsor
Relating to fraud prevention and verifying eligibility for benefits under Medicaid.

Maddy summaryHB 4273 requires Texas Medicaid officials to conduct regular electronic data checks to verify recipient eligibility, directly affecting Medicaid beneficiaries and the Texas Health and Human Services Commission. Key provisions include monthly verification of lottery winnings, death records, and out-of-state transactions, plus quarterly checks of voter registration status to identify potential eligibility changes. The bill prohibits accepting self-reported income, residency, citizenship, or household composition for Medicaid eligibility, replacing it with mandatory data matching. These changes aim to strengthen verification processes for Medicaid benefits under Texas law.

Co-sponsor SB 2309
Passed · Texas Senate · Co-sponsor
Relating to election integrity and security of ballot boxes, including by preventing fraud in the conduct of elections in this state; authorizing a penalty.

Maddy summarySB 2309 requires counties with populations over 100,000 to install video surveillance systems in all areas storing voted ballots, from delivery until final canvass, with public livestreams showing visible clocks. It also expands election watcher access to observe ballot box sealing, transfer, and processing at all handling locations. The bill directly affects large-county election offices and their ballot processing procedures. Key mechanisms include mandatory video monitoring of ballot storage areas and formalizing observer rights during ballot transport. These provisions aim to increase transparency during election processing without specifying new penalties or fraud prevention measures beyond the stated requirements.

Co-sponsor SB 2639
Passed · Texas Senate · Co-sponsor
Relating to the designation of a property as a historic landmark and the inclusion of a property in a historic district or similar preservation district by certain municipalities.

Maddy summaryThis bill (SB 2639) modifies Texas law to change how cities with populations over 950,000 can designate properties as historic landmarks or include them in historic districts. It requires property owner consent for designation, unless the city follows a specific process: providing a detailed impact statement (listing costs, tax benefits, and repair requirements) and making a written compensation offer to the owner if they object. If the owner rejects the offer, the city can seek court approval to proceed, with a judge appointing commissioners to assess damages. The law directly affects property owners in large Texas cities and aims to balance historic preservation with property rights.

Co-sponsor SJR 85
Passed · Texas Senate · Co-sponsor
Proposing a constitutional amendment authorizing the legislature to increase the amount of the exemption from ad valorem taxation by a school district of the market value of the residence homestead of a person who is elderly or disabled.

Maddy summarySJR 85 proposes a constitutional amendment to increase Texas school district property tax exemptions for elderly or disabled homeowners. Currently, the exemption for these residents is $10,000; this bill would raise it to $60,000 of a home's market value. The amendment would allow the legislature to adjust this exemption amount, with provisions ensuring eligible individuals (65+ or disabled) cannot receive both the basic exemption and this enhanced benefit. It directly affects Texas homeowners aged 65 or older or with disabilities who own their primary residence. The bill requires voter approval after legislative passage to take effect.

Co-sponsor SB 2529
Passed · Texas Senate · Co-sponsor
Relating to the vote required by the governing body of a taxing unit to adopt an ad valorem tax rate that exceeds the voter-approval tax rate or authorize the issuance of tax bonds.

Maddy summarySB 2529 requires local taxing units (like cities, school districts, or water districts) to obtain a supermajority vote from their governing body before adopting tax rates exceeding voter-approved limits or issuing certain bonds. Specifically, it mandates at least 60% approval for general obligation bonds and 75% approval for tax rates that exceed previously rejected voter-approved rates. The bill applies when a taxing unit seeks to raise taxes above the rate voters previously rejected in an election. This policy change directly affects local government decision-making on tax increases and bond issuances.

Co-sponsor SB 383
Passed · Texas Senate · Co-sponsor
Relating to the interconnection to the ERCOT power grid of certain coastal facilities for the provision of electric service.

Maddy summarySB 383 prohibits Texas' Public Utility Commission from approving interconnection of offshore wind power facilities to the ERCOT grid under specific conditions. The bill requires the Commission to deny approvals if a facility might negatively impact shipping routes, tourism, fishing, wildlife, migratory patterns, or public safety in disaster-prone areas, or if existing services are sufficient. It directly affects offshore wind developers and the Commission's approval process for grid connections. The law takes effect immediately if passed with a two-thirds vote, or September 1, 2025, otherwise.
