item 7 , management 's discussion and analysis of financial condition and results of operations to our annual report on form 10-k for the fiscal year ended december 31 , 2019 , which discussion is incorporated herein by reference . acquisition of aclara on february 2 , 2018 the company acquired aclara for approximately $ 1.1 billion . aclara is a leading global provider of smart infrastructure solutions for electric , gas , and water utilities , with advanced metering solutions and grid monitoring sensor technology , as well as leading software enabled installation services . the acquisition extends the utility solutions segment 's capabilities into smart automation technologies , accelerates ongoing innovation efforts to address utility customer demand for data and integrated solutions , and expands the segment 's reach to a broader set of utility customers . for additional information about the aclara acquisition , refer to note 3 — business acquisitions and dispositions in the notes to the consolidated financial statements . hubbell incorporated - form 10-k 21 organizational changes effective january 1 , 2021 the company consolidated the three business groups within its electrical segment , and renamed the segment as hubbell electrical solutions ( `` electrical solutions `` ) . the electrical solutions segment unites businesses with similar operating models , products , and go to market strategies under one operating banner and common leadership to drive synergies and long-term growth opportunities . also effective january 1 , 2021 the company moved its hubbell gas connectors and accessories business , from the electrical solutions segment to the utility solutions segment to create synergies with the existing gas products offered within the utility solutions segment and to better serve its utility customers . the hubbell gas connectors and accessories business represented approximately $ 157.1 million of net sales and $ 19.4 million of operating profit in 2020. the company will report its segment results under this revised reporting structure beginning with the filing of its quarterly report on form 10-q for the first quarter ended march 31 , 2021 . 22 hubbell incorporated - form 10-k impact of the covid-19 pandemic during march 2020 , a global pandemic was declared by the world health organization related to the rapidly growing outbreak of a novel strain of coronavirus ( covid-19 ) , which began to affect the company 's business and operations late in the first quarter of 2020 and became more pronounced during the second quarter of 2020 as foreign and u.s. federal , state and local governments reacted to the public health crisis with mitigation measures , including the shutdown of large portions of the u.s. and global economies . the pandemic continues to significantly affect u.s. and global economic conditions as governments , businesses and individuals react to the covid-19 pandemic and efforts to reopen their respective economies . as of december 31 , 2020 , there continues to be significant uncertainty around the scope , severity , and duration of the pandemic , as well as the breadth and duration of business disruptions related to it and the overall impact on the u.s. and global economies . the extent to which the coronavirus pandemic affects our business , operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict including new information that may emerge concerning the severity of the covid-19 pandemic , additional outbreaks or resurgence of covid-19 , the timing and availability of vaccines and effective treatments and the actions taken to contain it or respond to its health and economic effects . most of our manufacturing operations are currently deemed essential and continue to operate . our top priority has been to take appropriate actions to protect the health and safety of our employees . we have adjusted standard operating procedures within our business operations to ensure the continued safety of those within our locations and continually monitor health guidelines to ensure ongoing compliance and protection of our employees . these procedures include expanded and more frequent cleaning within facilities , implementation of appropriate social distancing programs , shift changes , requiring use of certain personal protective equipment , screening protocols and work from home programs , as applicable . despite these efforts , the covid-19 pandemic continues to pose the risk that our employees , contractors , suppliers , customers and other business partners may be prevented from conducting business activities , partially or completely , for an indefinite period of time , including due to shutdowns that may be requested or mandated by governmental authorities or imposed by our management , or that the pandemic may otherwise interrupt or impair business activities . we have developed action plans for a wide range of scenarios , but given the uncertainty regarding the magnitude and duration of the pandemic 's effects , it is impossible to predict with specificity or quantify the future impact on our business , financial condition and results of operations . in the second quarter of 2020 certain of our manufacturing operations and installation services were temporarily disrupted by shutdowns mandated by government authorities and from actual and potential exposure to covid-19 , negatively affecting sales volume and contributing to operating inefficiencies , such as a decrease in manufacturing cost absorption in the quarter . these temporary disruptions included work stoppages in several of our manufacturing operations in the u.s. , mexico , and the united kingdom . we also experienced a temporary stoppage of certain large meter installation services within our aclara business . story_separator_special_tag as a result , earnings per diluted share in 2020 decreased 12.0 % compared to 2019. adjusted earnings per diluted share in 2020 decreased 6.7 % as compared to 2019. segment results electrical solutions replace_table_token_5_th the following table reconciles our organic net sales to the directly comparable gaap financial measure ( in millions and percentage change ) : replace_table_token_6_th net sales of the electrical solutions segment in 2020 were $ 2.3 billion and decreased by $ 362.1 million , or 13.8 % as compared to 2019. organic net sales in 2020 declined by 13.6 % as compared to the same prior year period due to lower unit volume , primarily driven by the unfavorable effects of the covid-19 pandemic on demand . net sales in 2020 also declined , by less than 1 % from the effect of acquisitions and dispositions , as the decline from the disposal of the haefely business was greater than net sales added by acquisitions . within the segment , the aggregate net sales of our commercial and industrial and construction and energy business groups decreased in 2020 by approximately 14 percentage points as compared to the prior year , primarily due to lower volume driven by the unfavorable impact of the covid-19 pandemic on demand , partially offset by favorable price realization . net sales of our lighting business group in 2020 declined by approximately 14 percentage points as compared to the prior year period due to lower unit volumes also driven by the unfavorable effects of the covid-19 pandemic on demand . within the lighting business group , net sales of commercial and industrial lighting products in 2020 decreased by approximately 22 % compared to the prior year period driven by lower overall market demand , as well as softness in our national accounts . net sales of residential lighting products increased by approximately 6 % in 2020 as compared to the same prior year period due to strength in home center and e-commerce sales , partially offset by weakness in home builder markets in 2020 as compared to the prior year . operating income of the electrical solutions segment in 2020 was $ 234.8 million and decreased approximately 27 % compared to 2019 , while operating margin in 2020 decreased by 180 basis points to 10.4 % . excluding amortization of acquisition-related intangibles , adjusted operating margin decreased by 170 basis points to 11.4 % in 2020 as compared to 2019. the decrease in operating income and operating margin in 2020 is primarily due to lower net sales volume and inefficiencies related to the pandemic and higher stock based compensation expense due to the change in timing of our annual equity grants . these items were partially offset by favorable price realization and material costs , higher savings from our restructuring and related activities , savings from productivity initiatives and lower costs due in part to the impact of compensation actions and other cost reductions associated with the covid-19 pandemic . 28 hubbell incorporated - form 10-k utility solutions replace_table_token_7_th the following table reconciles our organic net sales to the directly comparable gaap financial measure ( in millions and percentage change ) : replace_table_token_8_th net sales in the utility solutions segment in 2020 were $ 1.9 billion , down 2.2 % as compared to 2019 , due to a 3.1 % decline in organic net sales resulting from restrictions associated with the pandemic on project deployments and installations , partially offset by higher end-market demand in the electrical transmission and distribution markets , an increase in storm-related sales as compared to the prior year , and favorable price realization . acquisitions contributed 1.3 % to net sales growth in 2020 and foreign exchange was slightly unfavorable by 0.4 % . within the utility solutions segment , net sales of our power systems business group in 2020 increased by approximately 5 % as compared to the prior year driven by domestic demand in the utility transmission and distribution markets as well as net sales growth from acquisitions and higher storm-related sales as compared to the prior year . net sales of the aclara business group in 2020 decreased by approximately 15 % as compared to the prior year primarily driven by restrictions associated with the pandemic on project deployments and installations . operating income in the utility solutions segment in 2020 increased by 8 % to $ 298.2 million as compared to 2019. operating margin in 2020 increased to 15.5 % as compared to 14.1 % in 2019. excluding amortization of acquisition-related intangibles the adjusted operating margin in 2020 increased by 160 basis points to 18.2 % as compared to the prior year . that increase was primarily driven by savings from our productivity initiatives and lower cost inflation , due in part to the impact of compensation actions and other cost reductions associated with the covid-19 pandemic , favorable price realization , higher savings from restructuring programs and lower restructuring and related costs , and favorable net sales mix . those favorable items were partially offset by the impact of lower volume , covid-19 pandemic related inefficiencies and higher stock based compensation expense due to the change in timing of our annual equity grants . hubbell incorporated - form 10-k 29 financial condition ,
