The contract's cost savings to the public entity must be guaranteed each year during the term of the agreement. The savings must be sufficient to offset the annual costs of the contract. Any initial payment from funds other than an installment agreement must also be offset by savings, as described herein, over the term of the agreement. In calculating cost savings, the public entity may consider capital cost avoidance and include additional revenue that is directly attributed to the performance-based efficiency contract. The contract shall provide for reimbursement to the public entity annually for any shortfall of guaranteed savings. Savings must be measured, verified and documented during each year of the term and may be utilized to meet the annual debt service. This section shall constitute the sole authority necessary to enter into performancebased efficiency contracts, without regard to compliance with other laws which may specify additional procedural requirements for execution of contracts.
