An underground equipment vault for power and electronic equipment includes an airflow system in combination with an above ground forced air source. The airflow courses through separate first and second chambers including a first chamber for power supplies and a second chamber for energy storage equipment. This airflow, sequentially traversing both chambers, dissipates heat from the equipment and further dispels hydrogen gases from the batteries to the outside air. An airflow system, utilizing fans, provides positive pressure to force the desired airflow through the chambers. The vault is closed with a dual lid structure to supply supporting strength and also supply a secure seal for closing the vault. The dual construction provides an insulating space for further insulating the vault from ambient conditions.
