MEMO: - Energy efficiency & reliability; Estimate of savings lost in Ohio from 3 years without electric IOU energy

Ehrendreich / MEEA 1/24/2024 The goal of this analysis was to look at the energy and demand savings that could have occurred over the last three years in Ohio if electric investor-owned utility energy efficiency had continued in the state, through the lens of electric system reliability. [...] The red curve shows the probability distribution of the electric load – the chance that end-use customers will be drawing a given number of megawatts of electricity from the electric grid. [...] With the original red load curve, the area where those curves overlap – in yellow in the zoomed in area – is the chance of having a blackout. [...] Link Lost Savings To estimate the savings that could have been achieved over the three years that Ohio has not had electric investor-owned utility (IOU) energy efficiency, the analysis started with the results from the last year of energy efficiency programs, 2020. [...] The additional energy and demand savings that could have been achieved over the last three years would have had a substantial impact on the energy needs of Ohio utility customers and could have lessened the risk that is being felt today.
