A strong infrastructure is the heart of our economy. It is the oil, natural gas and electricity that power business, industry and our daily lives. It is the pipes and wires that connect our homes, factories, offices and stores to bring them to life. It is the transportation network of roads, highways and airports that keeps our economy moving. Infrastructure is our business. MDU Resources Group provides value-added natural resource products and related services that are essential to energy and transportation infrastructure. Our company was founded in 1924 as a small electric utility serving a handful of farm communities on the border of Montana and North Dakota. We realized early the value of delivering a variety of services, and grew our company by developing a core line of businesses. Today, we are a multibillion-dollar corporation with operations and customers across the country. MDU Resources is the largest publicly traded company headquartered in the four-state region of North Dakota, South Dakota, Montana and Wyoming, and we do business in 44 states. Since 1948, our stock has been traded on the New York Stock Exchange. It trades under the symbol MDU.

On May 30, 1979, by virtue of Law #57, the Puerto Rico Water Resources Authority changed its name to the Puerto Rico Electric Power Authority. The change was due to new circumstances, because water or fuentes fluviales no longer were the principal source of electricity on the Island. In 1981 PREPA acquired the electric system owned by the Municipality of Cayey. In this way came about the completion of the consolidation of all electric systems in Puerto Rico under one sole entity.
