WV SB583

Creates the "West Virginia-Powered Data Center Incentive Act" requiring qualifying data centers to invest at least $50 million, create 50+ jobs, and use coal-generated electricity for at least 80% of primary operational capacity

Provides special property tax treatment for qualifying data centers, assessing personal property at salvage value (lower of fair market salvage value or 5% of total value) rather than full market value

Exempts qualifying data centers from state sales and use tax on equipment and tangible personal property purchased for operation and maintenance

Exempts coal-fired power plants from business and occupation (B&O) tax on electricity generated and sold to qualifying data centers

Requires data centers that cease operations, fail to meet coal-generated electricity requirements, or fail to maintain job creation thresholds within five years to repay three years of claimed tax benefits
