In the last years, electricity retail tariffs have been pressured upwards mainly due to the strong increase in the costs related to taxes and policy Retail tariff components Evolution of electricity retail tariff components in the EU cent/kwh, 2008-2014 > Energy Costs are related to production in power plants, trading & selling, customer service > Network Costs related to transport and distribution activities > Tax & Policy Costs Costs are related to taxes and energy policy such as: renewable and CHP support, nuclear decommissioning, vulnerable customers, etc. Source: Eurelectric 14
There is an imbalance between the way costs are charged to final consumers and the underlying structure of costs... Charge structure Underlying costs Match? Energy Mostly kwh Mostly kwh YES Network Mostly kwh Mostly kw NO Taxes and Policy costs Mostly kwh Fiscal nature (Taxes) Mostly kw (Policy) NO 15
... which generates a significant mismatch between the costs and the revenues structure in the power sector in several countries Structure of costs and revenues of the power sector by country 1 100% 80% Fixed 60% 40% Variable 20% 0% Cost Revenues Cost Revenues Cost Revenues 1.

Charging fixed costs through a variable retail tariff leads to distortive incentives to reduce demand from the grid Representation of tariff deficit creation due to demand reduction Comments M Revenues Costs > A demand contraction causes a reduction of revenues by α, which is higher than the cost reduction of the system (β), thus leading to a tariff deficit β Deficit Breakeven > Increase power demand costs α to the consumer, but only costs β to the system (α> β) α V 1 V 0 Volume This penalizes demand electrification and overvalues investments that reduce demand at grid (energy efficiency and distributed generation) Clients with higher load factors are paying more than the costs that the system incurs to satisfy that demand, so as to subsidize clients with lower consumption 17
This cost to price mismatch leads to a vicious cycle, where system costs will be charged over few(er) customers, increasing the consumer divide Reduction of grid demand DER 1 Loss of revenues > cost reduction Tariff increase required Behavior change Recovering the revenue gap through tariff increases will: Push costs to consumers who didn t invest in distributed resources ( consumer divide ) Increase profitability to invest in distributed resources ( death spiral ) Customer assessment 1.

There are historical reasons for these distortions, but the context has changed and the associated inefficiencies are now greater and need to be addressed Historical motivation Why need to change? Context Robust demand growth rates Power generation mix had a higher share of technologies with high variable cost Power demand stagnation / reduction Increased penetration of technologies with low or null variable cost Emissions/ Energy Efficiency Higher variable tariff provides stronger incentive to reduce demand, contributing thus to energy efficiency and the reduction of greenhouse gas emissions Decarbonization of the power sector With RES abundance, energy efficiency is not about reducing demand, but instead consuming when energy is more abundant Innovation Customers had no viable technological option to reduce grid demand without loss of service Set of new technologies (energy efficiency, storage, distributed PV) allows change in grid demand without changing the clients service level Equity A highly variable tariff protects consumers with low load factors (progressive effect) Equity is more effectively achieved with special mechanisms to vulnerable consumers A highly variable tariff over-incentivizes new technologies, penalizing consumers who are not able to invest (regressive effect) 19
The tariff structure also over incentivizes investment in distributed resources over centralized plants, which are more economical Solar LCOE vs Revenues/Savings by segment in Portugal 1 ( /MWh, 2015) LCOE Variable retail tariff 160 140 Return for investor is higher with investment in distributed resources 120 100 80 60 40 20 However, the optimal for the society would be if these investments were in centralized generation (not only in utility-scale solar, but also in thermal and in other mature renewables) 0 Residential Commercial Industrial Utility-Scale Distributed Generation 1.

Key messages In order to reach Europe s ambitious decarbonization goal, a strong push for RES and efficiency is needed The costs of renewable energy have decreased steeply, namely for wind and solar PV, leading to frequent upwards revisions in the forecasts of installed capacity for these technologies This increase in intermittent power generation needs to be accompanied by investments in technologies that provide flexibility to the system (ex: storage, smart grids, DSM...) to guarantee grid stability In this context, the concept of energy efficiency is evolving from consuming less to consuming smart Electrification of transports and H&C is essential for the decarbonization process, not only due to reduced overall energy consumption (more efficient electric technologies), but also due to the ability to use RES sources in electricity There is a mismatch between costs and revenues structure in the power sector, which generates several distortions, namely biased signals for investment decisions and financial imbalances in the system The fact that fixed costs are being recovered through a variable tariff leads to biased price which favors reduction of grid demand, which in turn will lead to a vicious cycle where system costs will be charges over few(er) consumers Furthermore, distorted tariff structure favors investments in distributed resources over centralized plants, which implies a social welfare loss EDP Comercial has launched its solar energy offer, with solutions designed to fit each customer characteristics EDP solar energy customers receive a re:dy for free a home energy management system which allows them to monitor and optimize their energy consumption pattern and use of solar energy, thus contributing to maximize the benefits of clients investment and to improve system s flexibility 31
