Regulatory period: 2020-2025 • Remuneration calculated by WACC methodology and reviewed every 6 years (regulatory period): 6.003% (before taxes) in 2020 and 5.58% from 2021 onwards. Until 31 December 2019 the remuneration was linked to 10 Year-Treasury Bond (6.5%)

• The remuneration has four components: i. Remuneration of net regulatory asset value (CAPEX): It maintains the regulatory asset (RAV) of investments made until 2018. o Remuneration of existing assets at 31 December 2014 calculated according to Royal Decree 1048/2013 (Standard Costs (SC) are the reference for calculating regulatory assets): o SC corrected by a coefficient per company o Ceded assets are subtracted (assets prior to 1998 are estimated) o Assets are remunerated during their regulatory useful life (depending on accountability by company) o Assets in operation since 1 January 2015 until 31 December 2018 o Intermediate value between Standard Costs and audited cost o Assets are remunerated during their useful life (40 years for network assets and 12 for control systems) o New assets in operation since 1 January 2019: audited cost per installation ii. Remuneration of Manageable Component (OPEX): o O&M and “Other assets investments” (systems not associated with digitalization, machinery, vehicles, buildings and tools): This term evolves according to the increase in remuneration for investment in electricity assets and with an adjustment factor, which takes the value of 0.97 per year, with the aim of bringing it closer to the real cost of the companies. o Efficiencies: companies are able to retain 100% of the efficiency gains obtained from the OPEX additional to the previous adjustment factor iii. Other regulated tasks: reading, contracting, defaults, invoicing, customer service channels, planning and structure… according to SC and public domain use tax -7% compared to the previous period

iv. Incentives: o Quality and losses reduction: Each company will have bonuses or penalties, so that the whole is a "zero-sum".

How to model

Approach for Network Income Calculation

+ Rate Base * Equity Ratio(1) * Regulatory ROE (8 utilities)

Other Income: • Allowance for funds used during construction (AFUDC) • Carrying costs on regulatory assets & liabilities + not included in Rate Base • Be sure to tax effect values

+ Equity Investments (GenConn, NY Transco) = Networks “Income”

Economics

• Rate Base = Gross plant in service - Book depreciation - Deferred income taxes +/- working capital +/- regulatory assets & liabilities (not accruing carrying costs) + prepaid + materials and Rate Base supplies • Average rate base for a 13-month period used for gas and electric distribution and UI transmission. Year-end rate base used for CMP Transmission

• Utilities accrue AFUDC on longer-term construction projects prior to being placed in-service AFUDC & Carrying • Utilities accrue Carrying Costs on certain regulatory assets & liabilities not in rate base Costs • This has an impact on current earnings, but there is no current cash flow impact

• 50% JV with affiliates of Clearway Energy (GenConn) in 2 regulated peaking plants with ROE of Equity 9.85% Income • 20% investment in NY Transco: Rate Base $204M, ROE 10%, Equity Ratio 53%

• Allowed rate of return (before taxes) of 7.398% until 2031 for facilities in operation before RDL 9/2013. For facilities in operation after RDL 9/2013, allowed rate of return of 7.09% until 2025 following CNMC published WACC methodology For those facilities in operation before RDL 9/2013 with any pending arbitration or judicial proceeding related to the modification of the Remuneration Regime after RD 661/2007, early termination of arbitration or judicial procedure or the waiver of the perception of compensation is a mandatory requirement prior to obtain the 7.398% allowed rate of return until 2031. (Royal Decree Law 17/2019) • Remuneration based on revenues from market participation, with a specific additional remuneration articulated in two terms: - RI: A term per unit of installed capacity (€/MW) that covers the investment costs of a standard installation that cannot be recovered by the sale of energy. Allowing the installation to achieve a reasonable return defined by the Government. - RO: A term for operation (€/MWh) that covers the difference between operating costs and the revenues from the market participation of such standard installation. The installation of renewable energies, cogeneration or waste will not receive such remuneration for operation as long as its income from the sale of electricity in the system is higher than its operating costs. • Parameter modification: - Every 6 years all the parameters could be changed (including reasonable return) for the remaining useful life, except for the useful life and standard value of the initial investment of an installation; - Order TED/171/2020 establishes the remuneration parameters to estimate the regulated remuneration of renewables and cogeneration for the 2020-2025 regulatory period. The main changes are: • It has recognized a higher cost of CO2, a higher fuel price (which improves the RO of these plants by 14 €/MWh) and the remuneration for the cost of the System Operator (0.14 €/MWh) - Every 3 years, and for the rest of the regulatory period, the estimation of revenues from the market will be reviewed, valuing the energy sold at market price based on market price evolution and the forecast for operating hours - At least annually, the values of remuneration for operation will be updated for those technologies whose operating costs depend essentially on the price of fuel.

Depreciation • ~37 years average for windfarms on a straight line basis, net if ITC amortization

Other Taxes • Property, Franchise, and Payroll Taxes Expense

Other Income • Consists of: Finance income (primarily capitalized interest) combined with gains on non-current assets, & Deduction offset by other deductions (non-service pension costs & charitable giving)

Interest • Financial Expenses: consisting of intercompany debt and any other borrowings. Excludes TEI financing Expense costs, included within Minority interest under HLBV accounting.

• MACRs tax treatment allows wind & solar assets to be depreciated over 5 years Recorded in the tax line and captured through deferred tax assets Income Tax • ITC & PTC can only be utilized at consolidated level and after NOLs are monetized Line  PTCs generated over 10 years and can be used over 20 years  AGR is considered one taxpayer. After the NOLs are monetized, annual PTC utilization is limited to 75% of the consolidated tax liability

Minority • Minority Interest driven by HLBV accounting for tax equity structures. The HLBV method allocates earnings to the noncontrolling interest, which considers the cash and tax benefits provided to the tax Interest equity investors

Accounting criteria

• P&L  GAAP (10Q,10K): For periods after 1/1/2018, PTCs with Tax Equity are indirectly included in Net income/(loss) attributable to non-controlling interests and retained PTCs are booked in the income tax line. Prior to that, PTCs with Tax Equity were booked in revenues and retained PTCs in the income tax line.  IFRS (projections): All PTCs are booked in revenues. • Balance Sheet  For periods after 1/1/2018, PTCs with Tax Equity reduce ‘Non-controlling interests’ in the Equity section. In prior periods, PTC PTCs with Tax Equity reduced ‘Tax equity financing arrangements - VIEs’ in the Non-current Liabilities section.  Retained PTCs reduce deferred income taxes. • Cash Flow  Retained PTCs hit the ‘Deferred taxes’ line in Cash Flow from Operating Activities.  For periods after 1/1/2018, PTCs with TEI impact the ‘Distributions to noncontrolling interests’ line under Cash Flow from Financing Activities. For prior periods, PTCs with TEI impacted ‘Payments on tax equity financing arrangements’. These lines include payments of PTCs and remaining debt/equity.

• P&L  GAAP (10Q,10K): Booked on D&A (they lower D&A), below EBITDA ITC  IFRS (projections): Booked as Other Operating Income, above EBITDA • Cash Flow  ITCs provide an initial deferred tax benefit equal to 50% of the total ITC, recognized in year one.

• Wind farms under tax equity structures are fully consolidated in the consolidated balance sheet and the results of their operations (including depreciation) are reported in the consolidated statement of operations. Investors share is reported as Minority Interest.

Tax Equity • Recorded as a financing obligation and amortized with the allocation to the tax equity investor of its share of cash distributions, MACRS, PTCs, and the tax impact of taxable income. 67 RENEWABLES: MEXICO

Capacity payments

• Investment incentive : € 10,000/ MW per year during 20 years - For all installations built post 1998 which did not have any subsidized regime. - Received by all CCGTs and some hydro and pumping plants. - Initially it was established as a payment of € 20,000 /MW per year during the first 10 years of the plant life, but it was modified under the Royal Decree-Law 9/2013 that determined the current parameters. Under this new regulation, the remaining number of years entitled to receive this capacity payment were calculated for each installation, doubling the period and reducing the amount to the abovementioned €10,000. For this reason, the end of the incentive depends on the outstanding years in 2013.

• Environmental incentive (desulphurization plants): € 8,750 /MW per year during 10 years - For coal plants that installed desulphurization plants. - This incentive is close to end.

For facilities in operation after RDL 9/2013, allowed rate of return of 7.09% until 2025 following CNMC published WACC methodology For those facilities in operation before RDL 9/2013 with any pending arbitration or judicial proceeding related with the modification of the Remuneration Regime after RD 661/2007, early termination of arbitration or judicial procedure or the waiver of the perception of any compensation is a mandatory requirement prior to obtain the 7.398% allowed rate of return until 2031. (Royal Decree Law 17/2019) • Remuneration linked to 10 Year-Treasury Bond at the year “n” plus 300 bp, until 31 December 2019 (7.5%) and reviewed every 6 years (regulatory period) • Remuneration based on revenues from market participation, with a specific additional remuneration articulated in two terms: - RI: A term per unit of installed capacity (€/MW) that covers the investment costs of a standard installation that cannot be recovered by the sale of energy. This return on investment allows the installation to achieve a reasonable return defined by the Government. - RO: A term for operation (€/MWh) that covers the difference between operating costs and the revenues from the market participation of such standard installation. The installation of renewable energies, cogeneration or waste will not receive such remuneration for operation as long as its income from the sale of electricity in the system is higher than its operating costs. • Parameter modification: - Every 6 years all the parameters could be changed (including reasonable return) for the remaining useful life, except for the useful life and standard value of the initial investment of an installation; - Order TED/171/2020 establishes the remuneration parameters for estimating the regulated remuneration of renewables and cogeneration for the 2020-2025 regulatory period. The main changes are: • It has recognized a higher cost of CO2, a higher fuel price (which improves the RO of these plants by 14 €/MWh) and the remuneration for the cost of the System Operator (0.14 €/MWh) - Every 3 years, and for the rest of the regulatory period, the estimation of revenues from the market will be reviewed, valuing the energy sold at market price based on market price evolution and the forecast for operating hours - At least annually, the values of remuneration for operation will be updated for those technologies whose operating costs depend essentially on the fuel price. 96 GENERATION: SPAIN

• Price regulation exists for certain customer groups: o The default tariff cap came into force from 1 January 2019 and applies to customers on a standard variable rate tariff – impacting around 11 million customers*. The level of the cap is reviewed every 6 months, and is in place until at least year-end 2020, but may be extended annually until 2023 if Ofgem believe conditions are not in place for effective competition. o The safeguard tariff applies to prepayment customers (April 2017) – impacting around 4.5m customers. The level of the cap is reviewed every 6 months and the prepayment cap is in place until year-end 2020. Before the default tariff cap started on 1 January 2019, people who got the government’s Warm Home Discount and were on a default tariff (including standard variable tariffs) were protected by the Prepayment Price Cap.

Obligated support for low income and fuel poor customers

• Warm Home Discount scheme is government scheme aimed at addressing fuel poverty and takes the form of a one-off discount on energy bills set at £140. The scheme is paid to customers in low income groups or in receipt of pension credits, and is paid to approximately two million customers. • Energy Company Obligation Scheme is a government scheme to help reduce carbon emissions and tackle fuel poverty. The scheme requires suppliers to invest in energy efficient measures, the size of suppliers obligation is based on customer number and supply volumes.
