The repowered turbines are expected to qualify for production tax credits. Project spend related to repowering is anticipated to be approximately $2.4 billion from 2016 to 2020 • PacifiCorp’s Energy Vision 2020 includes implementation of wind repowering, new transmission, and development of 1,150 MW of new wind powered facilities (950 MW owned) for a total investment of approximately $3 billion from 2017 to 2020 • MidAmerican Energy is progressing on construction of up to 2,000 MW (Wind XI) of additional wind-powered generating facilities. As of September 2018, 424 MW had been placed in-service. An additional 727 MW are expected to begin generating by year-end 2018. The project is expected to be completed and in-service by 2019, with a cost cap of $3.6 billion. In May 2018, MidAmerican Energy filed for approval to construct up to 591 MW (Wind XII) at a cost cap of $922 million • BHE Renewables is constructing the 98 MW Community Solar Gardens project in Minnesota and the 212 MW Walnut Ridge facility located in Illinois. The combined investment for the projects is anticipated to be approximately $600 million. In April 2018, BHE Renewables completed its $495 million acquisition of the 300 MW Santa Rita wind facility located in Texas (1) Includes owned operating, under construction and in-development facilities. Excludes tax equity investments 17
Advancing a Sustainable Energy Future • We are leaders in the journey to a sustainable energy future – Through September 30, 2018, we have spent $23 billion on renewable energy, and have made commitments to spend an additional $5 billion on wind generation by 2020 – MidAmerican Energy is the largest owner in the U.S. of rate-regulated wind capacity with 6,007 MW in operation or under construction. In 2017, MidAmerican Energy generated wind energy equivalent to 51% of its Iowa customers’ annual retail electric usage. Assuming Wind XII is approved by the IUB and completed (expected late 2020), the company expects to generate renewable energy greater than 100% of the annual energy consumed in our Iowa service territory in 2021 – PacifiCorp is investing approximately $3 billion through 2020 developing new wind generation resources, repowering existing wind facilities, and building a new electric transmission line as part of EV 2020 – Owned coal-fueled capacity has declined as a percentage of BHE’s power capacity portfolio from 58% in 2006 to 28% as of September 30, 2018. Since 2013, BHE has retired or has plans to retire more than 4,500 MW (43% reduction) of coal capacity – Berkshire Hathaway Energy’s natural gas transmission pipelines’ operational practices and methane leak detection programs are designed to minimize the release of methane emissions. These leading practices resulted in the gas transmission pipelines’ combined leak rates, measured as a percentage of throughput, of 0.046% in 2017, which is significantly less than the industry average and the goal of the ONE Future Initiative of 1% – Additional information regarding our sustainability and environmental outlook can be found at www.berkshirehathawayenergyco.com/environment 18
BHE Asset Profile • Berkshire Hathaway Energy is growing its renewable energy portfolio and continues to de-risk its balance sheet as it relates to carbon-based generation assets. In 2017, only 10% of our overall net investment in property, plant and equipment was invested in coal generation assets, while 8% was invested in natural gas generation assets Net PP&E as of December 31, 2017 Berkshire Hathaway Energy Renewables, T&D, and Other 82% Natural Gas Generation 8% Coal Generation 10% MidAmerican Energy PacifiCorp Nevada Power Sierra Pacific 76% 85% 69% 9% 64% 35% 22% 18% 13% 6% 2% 1% 19

Northern Powergrid Regulatory Update • On April 30, 2018, Ofgem published its decision not to hold a mid-period review of the current electricity distribution price control (RIIO-ED1), noting that: – Ofgem ‘had not identified any issues that fitted within the scope’ of the mid-period review, as narrowly defined within its original price control decision; and – A wider mid-period review “could undermine regulatory confidence and weaken incentives” • Ofgem’s consultation on the broad regulatory framework for gas and electricity networks that will apply in the next price control (RIIO-2) closed in May 2018 – Ofgem published its decision on July 30, 2018, but did not take many firm positions – In summary: • There were no new insights on the likely cost of capital • The RIIO-ED2 price control will run for five years, instead of the eight years for RIIO-ED1 • Key regulatory mechanisms will likely stay in place for the next RIIO structure; and • Future regulatory asset growth will be indexed to a different measure of UK inflation, Consumer Price Inflation including owner occupiers’ housing costs (CPIH), rather than the UK’s retail price index (RPI). This change will affect Northern Powergrid from April 2023, but Ofgem may consider a transition period where CPIH is phased in. Taken in isolation, the net effect will be a modest advance of revenue to companies in the shorter term; offset by slightly less long-term inflation protection and lower long-term revenues – More detailed consultations will begin in December 2018 for gas, transmission and cross sector issues, whose price controls start in 2021. Consultations will begin in fall 2019 for electricity distribution issues, whose price controls start in 2023 32

Affordable Clean Energy Rule • Limited to onsite, heat rate improvements at coal-fueled facilities as best system of emissions reduction • Redefines and rebalances relative roles of federal government and states’ responsibilities with the EPA defining the legal standard of Best System of Emission Reduction with “candidate measures” and states determining what the “actual measures” need to be to improve efficiency • States would be required to evaluate heat rate improvement candidate technologies and measures to establish unit-specific standards of performance, measured in terms of pounds of carbon dioxide per megawatt hour • States will have three years from finalization of the rule to submit plans to the EPA, which would have one year to determine approvability.
