The energy efficiency upgrades are part of the energy savings performance contract (ESPC) awarded to ESG last year.

ESG has announced that the comprehensive energy infrastructure improvements, lighting retrofits, heating and cooling system upgrades, and water conservation measures implemented at the Parnall Correctional Facility will result in total life cycle savings of over $30m.

The ESPC project implemented by ESG equates to direct savings to Michigan taxpayers.

The company claimed Parnall’s utility costs will be reduced by about 40% and water consumption costs will be reduced by about $2m, over the ten-year term of the ESPC contract.

ESG guarantees the savings will meet annual payments to cover the $12.89m project costs.
