2020 HPWREN Accomplishments Including One Year Under Covid

2020 was a year to remember for HPWREN and everyone else. The first two and a half months were fairly normal with routine maintenance and upkeep to maintain services through the winter months when generally there is little fieldwork. One significant accomplishment was the installation of the SDGE supported San Juan Hills site including ALERTWildfire and HPWREN cameras in January 2020.
