Electric cooperatives want to help bridge the digital divide between rural and urban America as more federal funding becomes available for rural broadband. But a 77-year-old law may prevent one of the nation’s poorest states from fully tapping into millions of new federal dollars to expand high-speed internet service to needy rural communities.Mississippi is among the states that rely most heavily on rural electric cooperatives, nonprofits that deliver power to their members in rural areas. Mississippi’s electric cooperatives’ service area covers 85 percent of the state's land mass.Yet since 1942, Mississippi state law has restricted its cooperatives to working in electric services. Its legislature is expected to take up bills that challenge the state law and the role of electric cooperatives early in its session that began on Jan. 8.Should the Magnolia State change its law, its electric cooperatives could compete for $350 million in loans and grants set aside to improve broadband access under the federal farm bill Congress passed last month. They also could go for a separate pilot program the U.S. Department of Agriculture (USDA) announced days later that offers up to $600 million in loans and grants to connect rural areas that have poor broadband service.
