Other recent projects managed by Ameresco's local team in the Helena, Mont., office include a $1.6 million energy savings performance contract (ESPC) with Lewis and Clark County and a $3.2 million ESPC with the Kalispell School District. Both projects required critical energy efficiency and infrastructure upgrades that are guaranteed to decrease annual energy and operations costs, but are budget-neutral and will be repaid through energy savings over the contract term.
