Affordable Clean Energy Rule • Limited to on-site, 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. If a state does not submit a plan or a submitted plan is not approved, the EPA would have two years to develop a federal plan • Does not repeal the EPA’s greenhouse gas endangerment finding, although the EPA continues to evaluate the same • Comments were due October 31, 2018. Final rule was delayed by government shutdown and is now expected by the end of second quarter 2019 • Full impacts will not be known until the rule is finalized and state plans are approved • Material impacts are not anticipated, as affected companies have historically pursued cost- effective plant efficiency improvement projects • Berkshire Hathaway Energy will continue to work with state regulators and key stakeholders to provide safe, reliable and affordable clean energy to our customers and reduce our carbon footprint

Wildfires • The Western Governors Association and key legislators are becoming more focused on the need for comprehensive plans to mitigate wildfire impacts to the residents of the western states. They are collaborating with jurisdictional federal administrators and the Department of Interior and are evaluating methods to better withstand the impacts of wildfires which have been increasing in frequency and scope • In California, Senate Bill 901 outlined a series of requirements for the state. California is the only state in PacifiCorp’s service territory that has inverse condemnation, which allows for strict liability if a fire is caused by an electrical facility owned by a utility, regardless of whether the utility was negligent in maintaining the facility • PacifiCorp analyzed fire history with ignition sources as available from CALFIRE data sources(1). – Utility power lines contributed to 0% in PacifiCorp’s California service territory, compared to 2.84% of all ignitions in all of northern California – To put that in perspective, lightning was a contributing factor to 63% of about 240 records in PacifiCorp’s California service territory, compared to nearly 54% of about 1,200 records in all of northern California • In Oregon, Gov. Kate Brown formed a blue ribbon panel, on which Stefan Bird will be a member • In Washington, public utilities commission staff members are beginning to look at the impacts of wildfires on electric reliability • In Utah, House Bill 135 seeks to establish a grant program for wildland fire prevention (1) The records used do not include grass fires of less than 100 acres or timber fires of less than 5 acres

California Service Territory and Wildfire Plan Objectives California Senate Bill 901 requires electric utilities to develop annual wildfire mitigation plans to prevent, combat and respond to wildfires within their service territories PacifiCorp provides electricity to approximately 45,000 customers via 63 substations and 3,300 miles of transmission and distribution lines across nearly 11,000 square miles Regulatory Steps Date Wildfire mitigation plans filed February 6, 2019 Workshop on plans held February 13, 2019 Focused issue-specific workshops held Week of February 25, 2019 Intervenor testimony on plans served March 4, 2019 Evidentiary hearings on plans held March 11, 2019 Concurrent opening & reply briefs/comments March 22 and March 27, 2019 California Public Utilities Commission approves wildfire mitigation plans May 6, 2019

Wildfire Mitigation Plans Berkshire Hathaway Energy has developed Wildfire Mitigation Plans (WMPs) across its Western Utilities WMP 2019 Overview: • Risk-based approach to identify FIRE High Consequence Area (FHCA) • FHCAs are determined by population and structure density, fuel loading, accessibility and climatology • Mitigation plans developed to minimize risk from electrical assets Key Components: • Enhanced situational awareness through active monitoring of Red Flag warnings, public weather data and installation of local weather stations • Yearly asset inspection frequency with accelerated correction time • Implementing increased vegetation clearance standards on distribution circuits of at least a 12-foot pruning cycle, with an objective of maintaining a 4 foot clearance in FHCA • Asset Hardening – Insulated conductor – Strategic pole replacement to increase loading capabilities and fire resiliency – Installation of additional Supervisory Control & Data Acquisition (SCADA) controls – Improved construction standards for new and retrofit applications to reduce potential ignition sources • Enhanced Operational Practices – Modified reclosing procedures during fire season – Proactive de-energization in FHCA – Line inspections before re-energization – De-energization for all areas – real time potential damage or fire risk is assessed by emergency response or emergency action center • Improved response through community outreach and coordination

Alberta Economic Outlook Economic Recovery Underway, but Challenges Linger Alberta • In 2018, Alberta was Canada’s third-largest economy and fourth-most populated province Alberta Real GDP Growth • After nation-leading growth of 4.5% in 2017, real GDP is expected to be 2.5% in 2018 7.0% 6.2% • Employment gains have been moderating compared to last year’s strong pace with the 5.7% province adding more than 42,000 jobs since October 2017. The unemployment rate has 5.0% 3.9% 4.5% averaged 6.7% year-to-date but is expected to decline to 6.3% in 2019 • With energy market access issues persisting in 2019, weaker corporate profits and slower 3.0% 2.5% oil production growth will dampen investment and exports for the year. Based on recent developments, 2019 growth is forecast to slow to 2.0% 1.0% • 2018 pool prices increased significantly due to the early retirement of some coal units and -1.0% impact of carbon tax price increase AltaLink -3.0% • No major system upgrades expected in the near-term.

AltaLink Regulatory Update Future Regulatory Files and UAD 2019-2021 General Tariff Application (GTA) – GTA filed August 23, 2018 – First three years of five-year commitment to flat tariffs at no higher than the 2018 approved revenue requirement of C$904 million – Key issues include depreciation/salvage rates, approval of new salvage methodology and whether a third year of the GTA should be included in the application – All rate relief measures maintain a FFO/Debt rating that supports an “A” category credit rating Utility Asset Disposition (UAD) – Under the UAD Decision dated November 26, 2013, utility shareholders are responsible for the net book value of utility assets that are taken out of utility service as a result of an “extraordinary retirement” before the original cost of the assets has been recovered from customers through depreciation – The Alberta utilities sought to have this decision addressed through legislative reform after having been unsuccessful in the courts. This led to the Alberta Government’s release of Bill 13 • In Q2 2018, the Alberta Government tabled Bill 13 which specifically recognized broad discretion in AUC’s powers including stranded assets and UAD matters • After receiving significant feedback from the financial community, debt and equity investors, the Alberta Government removed all references to UAD from Bill 13 • Alberta Government consultations are planned to resume post-2019 election

Northern Powergrid Regulatory Update • Northern Powergrid’s next price control starts in 2023 • The direction signalled by Ofgem for the forthcoming RIIO2 transmission and gas distribution reviews is more conservative: – The indicative base cost of equity of 4.0% (plus CPIH) is around 2.5 percentage points lower than the current allowed return – A general reduction in incentive strength and a cap on overall returns reduces the scope for outperformance and cash flow – The potential for the introduction of a complex cash flow floor mechanism reduces the pressure on Ofgem to properly compensate risks and ensure financeability • The remaining items, in isolation, appear manageable, however the general direction is to reduce the scope for outperformance • Our strong balance sheet protects Northern Powergrid from the credit risk injected by Ofgem’s wider RIIO2 thinking, but that position is not reflective of the entire sector • We will be among those pushing Ofgem hard to retain a focus on driving efficiency, outputs and long-term investment for customers through well-balanced, incentive- based price controls

U.K. Political Environment • Our assessment of Brexit’s impact on Northern Powergrid is unchanged – the fundamentals of our business are not directly affected by the outcome of negotiations • The nationalization rhetoric continues – it certainly has not increased in prominence; if anything, the likelihood has reduced: – Significant costs of implementation for minimal customer savings means the policy is not popular, even within much of the Labour Party, nor in many of its core supporters (e.g. a number of trade unions) – There is no sign of the Labour Party having the level of support that would be necessary to push something like this through • Our approach remains unchanged – we continue to provide the best possible service to our customers at low cost and continue to stay engaged with regulators and key stakeholders

Northern Powergrid Capital Investment Plan • Operating capital delivers our ED1 output commitments • The smart meter rental business continues to grow with capital expenditure expected in 2019 of £89 million, which is lower than the peak of 2017 as the industry transitions to the second generation of smart meters (£ millions) Current Prior 2019-2021 Plan Plan Operating £ 1,062 £ 1,062 Growth 98 98 Total £ 1,160 £ 1,160 500 400 £8 £134 £89 £98 £93 £1 300 200 £379 (£ millions) £329 £316 £329 £338 £345 100 - 2016 2017 2018 2019F 2020F 2021F Operating Growth

Growth Opportunities in the U.K. • Outlook for the Baltic Gas Project (49% owned by Northern Powergrid) remains encouraging – Final Investment Decision is likely by the end of 2019 • Smart meter rental continues to grow - but deployment has been delayed and is likely to continue into 2020 – Over 2.1 million smart meter units have been deployed to date and we have total contracted volumes of 2.9 million meters with an investment value of £460 million • Looking to the longer term, our existing network provides development opportunities - particularly as the low-carbon agenda continues to signal a need for more investment in networks • Transaction prices have remained high as corporate activity reshapes energy markets. We will continue to monitor opportunities
