of which were exported throughout Central America, expertly vacuum-packed. The factory employed more than 200 people. The coffee trade, known as the "golden grain", like that of basic grains, depends mainly on intermediaries who are responsible for collecting the product, storing it and then looking for points of sale. The marketing of vegetables in the town has not changed for many years. Traded directly by the plantation, the produce is transported to markets to find buyers. The cattle are sold by the owners directly to the national market in the slaughterhouses of Managua, Chontales or Condega, who are in charge of exporting them. Infrastructure The distribution of domestic energy, in charge of the company Distribuidora del Norte (DISNORTE), is interconnected to the national network. Hydroelectric energy generated by Centro América Plant supplies energy for much of the country. The plant has two turbines, each with a capacity of 25 MW (subject to a good winter). Public lighting service covers only 90% of the city and only 30% in rural areas. In some rural communities, they do not have access to electricity, particularly in dry zones such as La Ermita de Saraguasca and nearby places located 5 kilometers west of Las Lomas, despite the Larreynaga and Central America Power Plant located just 5 kilometers away.
