savings values are both 2 percent lower than those tracked by ENS. This difference is explained by a decrease in the NTGR value due to a reduction in 2017 spillover level compared to 2016. Green Heat The 2017 participation level for Green...
AI summary The Green Heat program saw increased participation in 2017, partly due to the eligibility of non-electrically heated homes for MSHP installations and the removal of pre-approval processes. However, energy savings were lower than expected due to decreased unitary savings for MSHPs and ASHPs and higher free-ridership levels for new participants. Peak demand savings were higher than tracked due to adjustments for installations in non-electrically heated homes.

AI summary The 2017 DSM Evaluation Report for Efficiency Nova Scotia (ENS) indicates that evaluated energy savings were 7% lower than tracked savings due to downward adjustments in unitary savings for BER Instant Rebates, particularly in LED products. Net energy savings were 11% below tracked savings, attributed to a decrease in the Net-to-Gross Ratio (NTGR) and higher free-ridership. Net peak demand savings were 40% below tracked savings, influenced by a drop in the Power Conversion Factor (PCF).
