From 2010 through 2018, regulated retail residential electricity prices nationwide increased by 11.3%, notably more than the 6.8% and 9.1% increases for commercial and industrial customers, respectively. As discussed in more detail below, data associated with the direct sale of power through retail choice programs are not included in these prices.
While this comparative price performance may be an anomaly, it conceivably could represent a developing trend, at least for the short term. Residential customers, while by far the largest in numbers, may not possess the level of political influence that the other major customer classes do in state legislatures and regulatory bodies. In addition, most residential customers may believe they are reasonably well served by the current situation, since the GDP Price Index increased by 14.8% from 2010 to 2018, more than the 11.3% electric price increase for residential customers.
The higher rate of residential price increases in the current decade may have been an attempt to correct a historical situation that found larger commercial and industrial customers paying more than their cost of service. We note, however, that cost of service studies and rate design are somewhat complicated, may have subjective aspects, and are not always fully transparent, thus, it is not at all times clear exactly what a specific customer class' cost of service is. Longer term, a continuation of higher relative residential price increases does not appear likely, since small customer complaints will eventually occur and find sympathy among at least some policymakers.
The pricing results for the three customer classes are somewhat different when the percentage price changes are compared for the 2000 to 2018 period. In this case, residential customer rates increased by 53.6%, higher than the commercial class hike of 44.4% but lower than the 56.1% increase for industrial customers. The GDP Price Index increased by 41.2% from 2000 to 2018.
This analysis is largely an offshoot of the Financial Focus June 12 report, "Regulated retail price of electricity — Average price per kWh falls in 2018." For the purposes of this analysis, the District of Columbia is considered a state, while no results are shown for Nebraska since it does not have investor-owned electric utilities.
The price changes by customer class are shown in the table below. A more extensive data table for all regulatory jurisdictions is provided toward the end of the report.
Looking at regulated retail residential electricity price changes for states that have restructured their electric utility industry versus those that have not provides mixed results. For the 2010-2018 period, of the 14 Tier 1 states, i.e., those that have fully restructured, 10 states — Connecticut, Delaware, the District of Columbia, Illinois, Maine, Maryland, New Jersey, New York, Ohio and Pennsylvania — show residential prices that have increased by less than the national average increase of 11.3%. However, when examining the eight Tier 2 states, i.e., those that have partially restructured, the data indicate that residential prices in only one state, Nevada, rose less than the 11.3% national average increase. For the 29 non-restructured Tier 3 states, only six — Arkansas, Colorado, Florida, Louisiana, North Carolina and Oklahoma — show residential electricity prices that have risen by less than the national average increase.
For the 2000 to 2018 period, the restructured versus non-restructured state comparisons, while slightly different, exhibit the same general trend. Of the 14 Tier 1 states, 10 states — Delaware, the District of Columbia, Illinois, Maine, New Hampshire, New Jersey, New York, Ohio, Pennsylvania and Texas — show residential prices that have increased by less than the national average increase of 53.6% over this time frame. For the eight Tier 2 states, the data indicates that residential prices in only one state, Arizona, rose less than the 53.6% national average. Regarding the 29 non-restructured Tier 3 states, 10 — Alaska, Arkansas, Florida, Iowa, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma and Vermont — show residential electricity prices that have increased at less than the national average.
Viewing the data from another perspective, the number of jurisdictions by restructuring tier with residential electric prices below the national average was unchanged for Tier 2 and was little changed for Tier 3 when comparing 2018, 2010 and 2000. In Tier 1 states, there were six jurisdictions with lower than average prices in 2018 compared to three in 2010 and four in 2000.
Comments on electricity price data
The data provided herein relates to power sold to retail electric customers of investor-owned utilities under rates that are subject to the oversight of state regulatory commissions; data associated with the direct sale of power through retail-choice programs are not included. There are currently 22 jurisdictions, i.e., those in Tier 1 and Tier 2, that have frameworks in place allowing electric generation to be offered competitively to at least a portion of customers in the state. The unavailability of the data associated with the direct sale of power through retail-choice programs likely results in an upward price bias for the commercial and especially the industrial classes, as well as for ultimate customers in restructured states, as the presumably lower-cost power obtained through retail choice is not reflected in the data.
While the data associated with the direct sale of power through retail-choice programs are not included in this study or the June 12 report, anecdotal evidence appears to indicate that very few residential customers and little residential electric load have switched to competitive suppliers. Thus, it can be reasonably concluded that the non-inclusion of the data associated with the direct sale of power through retail-choice programs has little effect on the residential prices included in these studies and on the comparison of residential prices in restructured versus non-restructured states.
Comments on RRA's electric restructuring tiers
Regulatory Research Associates, a group within S&P Global Market Intelligence, has placed each state regulatory jurisdiction and the District of Columbia in one of three tiers depending on the degree to which the state has restructured its electric industry. In Tier 1, power prices are competitively determined for all retail customers. In Tier 2, competitively priced power is limited to retail access customers, and in Tier 3, power prices are fully regulated for all retail customers. RRA currently places 14 states in Tier 1, eight in Tier 2 and 29 — including Nebraska — in Tier 3, as indicated in the below map. Electric industry restructuring commenced in the mid-to-late 1990s, and most states that restructured had done so by 2005.
The electric industry restructuring tier designations used in this study are from an Aug. 15, 2019, RRA report that ranks the various state regulatory jurisdictions.
