PHILADELPHIA â US Light Energy provided a presentation to the Indian River Board of Education recently regarding a proposed PILOT, payment-in-lieu-of-taxes agreement, for a community solar facility it is building for the benefit of the Tri-County Energy Cooperative. On Thursday night, during its regularly scheduled meeting, the board discussed the proposal and questions it would like answered before a decision is made. In 2017, US Light Energy was selected to construct eight megawatts of solar generating capacity for the benefit of the Tri-County Energy Cooperative and its 29 school district and municipal members. A megawatt is a unit of electrical power equal to one million watts.
