Acquisitions
When the state of Texas deregulated the electricity market, Houston Industries, the parent company of Houston Lighting & Power (HL&P), was broken up.[26] In 2003, Houston Industries was split into three companies. The power plants went to Texas Genco, CenterPoint Energy took over the distribution system, and the retail and wholesale electricity business became Reliant Energy.[27]
In 2006, NRG Energy bought Texas Genco from a group of private equity firms for roughly $5.9 billion.[28] Afterwards, in May 2009, NRG Energy acquired the retail operations of Reliant Energy. With those two moves, NRG's holdings represented most of the former HL&P and today serve 1.6 million customers in Texas. The retail operations continue to operate under the Reliant Energy name, while old Reliant's wholesale operations became RRI Energy.
Following the acquisition of Reliant, NRG extended its retail footprint with the acquisition of Green Mountain Energy in November 2010.[29] In doing so, NRG also became the largest retailer of green power in the nation, providing all of its Green Mountain and many of its Reliant customers with energy derived from 100% renewable resources.[30]
NRG Energy completed its acquisition of GenOn Energy in December 2012[31] for $1.7 billion in stock and cash.[32] The GenOn name was retired in the merger, but the combined company retained GenOn's Houston headquarters to coordinate operations.[31] That company, in turn, had been formed out of the merger of RRI Energy and Mirant Corporation in 2010.
In August 2013, NRG acquired Energy Curtailment Specialists, a Buffalo, New York-based Demand response company.[33] The terms of the deal were not disclosed.[34]
In March 2014, NRG Energy acquired Roof Diagnostics Solar (RDS), a residential solar power installation company, for an undisclosed amount. RDS headquarters remained in Wall Township, New Jersey while they operated under NRG Residential Solar Solutions.[35] That same month, NRG also acquired the retail power business of Dominion Resources Inc., which included Texas-based Cirro Energy and added 600,000 customer accounts to NRG Energy's retail business. Cirro Energy has continued to operate under the Cirro name.[36] In September 2014, NRG acquired Goal Zero, a manufacturer of personal solar power products.[37] The following month, NRG Energy acquired the residential solar company Pure Energies Group, which focused on web-based customer acquisition. This provided a simplified solar adoption process as well as a sales channel for Goal Zero.[38]
In March 2018, NRG acquired XOOM Energy, a mainly residential-focused, retail energy supplier with 300,000 RCE customers. The sale price was $210 million, which includes working capital and $6 million in transaction costs. It was an all-cash transaction that was funded with $75 million from excess cash and $135 million in debt. NRG Energy stated that the acquisition would serve to balance NRG's generation portfolio in the east.[39] In May 2019, NRG agreed to purchase Stream Energy for $300 million. The deal was finalized that August.[40]
In July 2020, NRG Energy and Centrica entered an agreement under which NRG would acquire Direct Energy for $3.625 billion in an all-cash transaction.[41] The deal was approved in January 2021, adding more than 3 million retail customers across 50 US states and 6 Canadian provinces.[42]
In December 2022, NRG announced the acquisition of Vivint Smart Home for $2.8 billion in cash, adding home security and automation to its vast product offer, expected to close in the first quarter of 2023.[43]
In May 2025, NRG announced the acquisition of the natural gas generation facilities and a commercial and industrial virtual power plant from LS_Power at a value of approximately $12 billion.[44]
