What will happen over the next five years? More renewables: merit order will shift further to the right > More fuel switch coal to lignite > Lower prices > Higher spot volatility Plant closures will accelerate > Capacity ranges for coal and gas in merit order will shrink > Gas will be running more often > Higher prices > More price spikes (spot/intraday) > Higher spot and then higher forward volatility > Re-appearance of risk-premium in forward prices Rise in gas and/or CO 2 prices > Higher prices Source: RWE > Higher forward volatility RWE Supply & Trading 01/04/2014 PAGE 20
Volatility, risk and risk premium is moving along the curve in the course of time > Volatility and risk in German and Continental power markets have moved to the very front end of the curve > This development led to backwardation of long-term contracts > During the last decade seasonal patterns became more pronounced: As a result generators react with seasonal mothballing > Such cycles can also be observed in other markets RWE Supply & Trading 01/04/2014 PAGE 21

Summary & conclusion 1 What are the market fundamentals telling us? > Prices for fuel commodities and CO 2 are drifting sideways > Despite reduction in subsidies, solar and wind generation will continue to grow in Germany > From 2015 onwards plant closures will reduce the current generous capacity margin > Electricity demand will drift sideways at best (assuming no major break-through on electric cars) 2 What can we observe in the traded market? > The markets assume that renewable generation capacity will grow faster than thermal plants are being closed > Lower dark spreads would signal to plant operators that their capacity is no longer required > More than 70 GW of renewable capacity in Germany push up intra-day volatility; sufficient flexibility in the system for the time being but more and more closures of conventional capacity will lead to spikiness in spot and intraday markets 3 How will future developments impact merit order economics? > Forward volatility is low right now as (1) coal plants are mostly price setting in average weather (assumption of forward market), (2) the volatility of coal is low > Spot/intraday volatility has gone up and is expected to rise further > Forward volatility likely to be pushed up if intraday price spikes become more frequent 4 Conclusions > Price to drift sideways for a while before markets tighten > More short-term price spikes will induce rising forward volatilities and risk premium and a change in hedging behaviour of large power consumers RWE Supply & Trading 01/04/2014 PAGE 24
