LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Introduction
Lazard’s Levelized Cost of Energy (“LCOE”) analysis addresses the following topics:
•     Comparative LCOE analysis for various generation technologies on a $/MWh basis, including sensitivities for U.S. federal tax subsidies, fuel prices,
      carbon pricing and costs of capital

•     Illustration of how the LCOE of onshore wind and utility-scale solar compare to the marginal cost of selected conventional generation technologies

•     Historical LCOE comparison of various utility-scale generation technologies

•     Illustration of the historical LCOE declines for wind and utility-scale solar technologies

•     Illustration of how the LCOEs of utility-scale solar and wind compare to those of gas peaking and combined cycle

•     Comparison of capital costs on a $/kW basis for various generation technologies

•     Deconstruction of the LCOE for various generation technologies by capital cost, fixed operations and maintenance expense, variable operations
      and maintenance expense and fuel cost

•     Overview of the methodology utilized to prepare Lazard’s LCOE analysis

•     Considerations regarding the operating characteristics and applications of various generation technologies

•     Summary of assumptions utilized in Lazard’s LCOE analysis

•     Summary considerations in respect of Lazard’s approach to evaluating the LCOE of various conventional and renewable energy technologies

Other factors would also have a potentially significant effect on the results contained herein, but have not been examined in the scope of this
current analysis. These additional factors, among others, could include: capacity value vs. energy value; network upgrades, transmission,
congestion or other integration-related costs; significant permitting or other development costs, unless otherwise noted; and costs of
complying with various environmental regulations (e.g., carbon emissions offsets or emissions control systems). This analysis also does not
address potential social and environmental externalities, including, for example, the social costs and rate consequences for those who cannot
afford distributed generation solutions, as well as the long-term residual and societal consequences of various conventional generation
technologies that are difficult to measure (e.g., nuclear waste disposal, airborne pollutants, greenhouse gases, etc.)

                        Note: The sensitivity analysis presented on this page also includes sensitivities related to the U.S. Tax Cuts and Jobs Act (“TCJA”) of 2017. The TCJA contains several provisions that impact the
                                LCOE of various generation technologies (e.g., a reduced federal corporate income tax rate, an ability to elect immediate bonus depreciation, limitations on the deductibility of interest
                                expense and restrictions on the utilization of past net operating losses). On balance the TCJA reduced the LCOE of conventional generation technologies and marginally increased the LCOE

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Levelized Cost of Energy Comparison—Sensitivity to Fuel Prices
Variations in fuel prices can materially affect the LCOE of conventional generation technologies, but direct comparisons to “competing”
renewable energy generation technologies must take into account issues such as dispatch characteristics (e.g., baseload and/or dispatchable
intermediate capacity vs. those of peaking or intermittent technologies)

Levelized Cost of Energy Comparison—Sensitivity to Carbon Pricing
Carbon pricing is one avenue for policymakers to address carbon emissions via a market-based mechanism; a carbon price range of $20 – $40/Ton
of carbon would increase the LCOE for certain conventional generation technologies to levels above those of onshore wind and utility-scale solar

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

 Levelized Cost of Energy Comparison—Sensitivity to Cost of Capital
 A key consideration in determining the LCOE values for utility-scale generation technologies is the cost, and availability, of capital(1); this
 dynamic is particularly significant for renewable energy generation technologies

                                   (1)     Represents the marginal cost of operating fully depreciated gas combined cycle, coal and nuclear facilities, inclusive of decommissioning costs for nuclear facilities. Analysis assumes that the salvage
                                           value for a decommissioned gas combined cycle or coal asset is equivalent to its decommissioning and site restoration costs. Inputs are derived from a benchmark of operating gas combined cycle,
                                           coal and nuclear assets across the U.S. Capacity factors, fuel, variable and fixed operating expenses are based on upper and lower quartile estimates derived from Lazard’s research.

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Levelized Cost of Energy Components—Low End
Certain renewable energy generation technologies are already cost-competitive with conventional generation technologies; a key factor
regarding the continued cost decline of renewable energy generation technologies is the ability of technological development and industry
scale to continue lowering operating expenses and capital costs for renewable energy generation technologies

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Levelized Cost of Energy Components—High End
Certain renewable energy generation technologies are already cost-competitive with conventional generation technologies; a key factor
regarding the continued cost decline of renewable energy generation technologies is the ability of technological development and industry
scale to continue lowering operating expenses and capital costs for renewable energy generation technologies

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Energy Resources—Matrix of Applications
Despite convergence in the LCOE of certain renewable energy and conventional generation technologies, direct comparisons must take into
account issues such as location (e.g., centralized vs. distributed) and dispatch characteristics (e.g., baseload and/or dispatchable
intermediate capacity vs. those of peaking or intermittent technologies)
•     This analysis does not take into account potential social and environmental externalities or reliability-related considerations

LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS—VERSION 14.0

Summary Considerations
Lazard has conducted this analysis comparing the LCOE for various conventional and renewable energy generation technologies in order to
understand which renewable energy generation technologies may be cost-competitive with conventional generation technologies, either now
or in the future, and under various operating assumptions. We find that renewable energy technologies are complementary to conventional
generation technologies, and believe that their use will be increasingly prevalent for a variety of reasons, including to mitigate the
environmental and social consequences of various conventional generation technologies, RPS requirements, carbon regulations, continually
improving economics as underlying technologies improve and production volumes increase, and supportive regulatory frameworks in certain
regions.

In this analysis, Lazard’s approach was to determine the LCOE, on a $/MWh basis, that would provide an after-tax IRR to equity holders equal
to an assumed cost of equity capital. Certain assumptions (e.g., required debt and equity returns, capital structure, etc.) were identical for all
technologies in order to isolate the effects of key differentiated inputs such as investment costs, capacity factors, operating costs, fuel costs
(where relevant) and other important metrics. These inputs were originally developed with a leading consulting and engineering firm to the
Power & Energy Industry, augmented with Lazard’s commercial knowledge where relevant. This analysis (as well as previous versions) has
benefited from additional input from a wide variety of Industry participants and is informed by Lazard’s many client interactions on this topic.

Lazard has not manipulated the cost of capital or capital structure for various technologies, as the goal of this analysis is to compare the
current levelized cost of various generation technologies, rather than the benefits of financial engineering. The results contained herein would
be altered by different assumptions regarding capital structure (e.g., increased use of leverage) or the cost of capital (e.g., a willingness to
accept lower returns than those assumed herein).

Key sensitivities examined included fuel costs, tax subsidies, carbon pricing and costs of capital. Other factors would also have a potentially
significant effect on the results contained herein, but have not been examined in the scope of this current analysis. These additional factors,
among others, could include: capacity value vs. energy value; network upgrades, transmission, congestion or other integration-related costs;
significant permitting or other development costs, unless otherwise noted; and other costs of complying with various environmental
regulations (e.g., carbon emissions offsets or emissions control systems). This analysis also does not address potential social and
environmental externalities, including, for example, the social costs and rate consequences for those who cannot afford distributed
generation solutions, as well as the long-term residual and societal consequences of various conventional generation technologies that are
difficult to measure (e.g., nuclear waste disposal, airborne pollutants, greenhouse gases, etc.).
