Essent Capital Market Day , 2 June 2010 Forward Looking Statement

This presentation contains certain forward-looking statements within the meaning of the US federal securities laws. Especially all of the following statements: > Projections of revenues, income, earnings per share, capital expenditures, dividends, capital structure or other financial items; > Statements of plans or objectives for future operations or of future competitive position; > Expectations of future economic performance; and > Statements of assumptions underlying several of the foregoing types of statements are forward-looking statements. Also words such as “anticipate”, “believe”, “estimate”, “intend”, “may”, “will”, “expect”, “plan”, “project” “should” and similar expressions are intended to identify forward-looking statements. The forward-looking statements reflect the judgement of RWE’s management based on factors currently known to it. No assurances can be given that these forward-looking statements will prove accurate and correct, or that anticipated, projected future results will be achieved. All forward-looking statements are subject to various risks and uncertainties that could cause actual results to differ materially from expectations. Such risks and uncertainties include, but are not limited to, changes in general economic and social environment, business, political and legal conditions, fluctuating currency exchange rates and interest rates, price and sales risks associated with a market environment in the throes of deregulation and subject to intense competition, changes in the price and availability of raw materials, risks associated with energy trading (e.g. risks of loss in the case of unexpected, extreme market price fluctuations and credit risks resulting in the event that trading partners do not meet their contractual obligations), actions by competitors, application of new or changed accounting standards or other government agency regulations, changes in, or the failure to comply with, laws or regulations, particularly those affecting the environment and water quality (e.g. introduction of a price regulation system for the use of power grid, creating a regulation agency for electricity and gas or introduction of trading in greenhouse gas emissions), changing governmental policies and regulatory actions with respect to the acquisition, disposal, depreciation and amortization of assets and facilities, operation and construction of plant facilities, production disruption or interruption due to accidents or other unforeseen events, delays in the construction of facilities, the inability to obtain or to obtain on acceptable terms necessary regulatory approvals regarding future transactions, the inability to integrate successfully new companies within the RWE Group to realise synergies from such integration and finally potential liability for remedial actions under existing or future environmental regulations and potential liability resulting from pending or future litigation. Any forward-looking statement speaks only as of the date on which it is made. RWE neither intends to nor assumes any obligation to update these forward-looking statements. For additional information regarding risks, investors are referred to RWE’s latest annual report and to other most recent reports filed with the Frankfurt Stock Exchange or SIX Swiss Exchange and to information available on the Internet at www..com.

Essent CMD | Facts & Figures | 2 June 2010 35 Renewables support framework in the Netherlands

Dutch Government has ambitious targets… …and is committed to support renewable energies

Share of renewables in primary > Since 2004 renewable energy was supported in the Netherlands by MEP energy consumption (“Milieukwaliteit Elektriciteits Productie”) grant scheme. The MEP subsidy awarding 6.0% was stopped by the government on 18 August 2006 2. > Since 1 April 2008 a new support scheme SDE (“Stimuleringsregeling Duurzame Energie”) is effective for new projects > MEP scheme for large-scale biomass co-firing is running out by 2015. A 20.0% subsequent scheme is still under consideration by the government. 11.6% 14.0% > Essent’s wind farms currently in operation and under construction have been granted a MEP subsidy (€77-78 /MWh for a maximum of 18,000 Full Load Hours 3.4% over 10 years). The future projects in the pipeline will qualify for the SDE subsidy.

2008 Gap EU target Gap NL target SDE support scheme (since 1 April 2008 for new projects) 2020 2020 for the > Onshore wind Netherlands – Subsidy granted for 15 years – The granted “cost-price” for wind onshore is defined at € 96 per MWh. 3 > Dutch Government targets 20 % share of renewables in overall The amount of full load hours is capacity dependent (standard: 2,200 p.a.) energy consumption by 2020, clearly surpassing the EU goal. – The yearly subsidy is the difference between the “cost-price” and the > This translates into a ~35% share in electricity consumption by estimated average market-price for wind power in that year. So called: 2020, which is ambitious and provides a prominent and “premium feed-in tariff” promising role for co-firing. > In the recent energy report1 the Dutch Government defined a > Offshore wind new target for wind power capacity by 2020: targets 6,000 MW – Support system for offshore is expected to be revised later in 2010 onshore and 6,000 MW offshore. due to the current system being not sufficient for most projects

1 Energy Rapport 2008 2 Essent Wind has no projects that were not initially awarded a subsidy 3 The cost price is for projects with application before end of 2008. The granted price can be different for later applications
