3. Mainstream founding principle “The world is on a once of transition from fossil fuels to sustainability, Mainstream exists to be a leader of this transition”

4. President Barack Obama inauguration address “We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms. The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition; we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries – we must claim its promise. That is how we will maintain our economic vitality and our national treasure – our forests and waterways; our croplands and snow capped peaks. That is how we will preserve our planet, commanded to our care by God. That's what will lend meaning to the creed our fathers once declared”

5. Ireland & UK 2020 Targets Synergy Ireland ●Electricity from Renewables by 2020 – 40% ●Equates to 4 GW installed by 2020 ●Currently 2 GW installed ●0.25 GW p.a. required to reach target ●16 GW waiting in Grid Queue! ●Clearly no shortfall ●Irish Wind potential = 345 TWh p.a. ●Equates to 19 x market size ●Significant opportunity to Export UK ●Electricity from Renewables by 2020 – 30% ●Equates to 35 GW installed by 2020 ●Currently 8 GW installed ●3.3 GW p.a. required to reach target ●22 GW in Grid Queue ●Shortfall of 5GW ●UK only installed 0.7 GW in 2011 ●Strong possibility of missing targets by a large margin

6. Mutual difficulties present mutual opportunities ●Ireland needs to attract investment ●Ireland needs to create jobs ●Ireland needs to export more ●Government needs money ●UK needs renewables ●UK needs energy ●UK needs to meet its climate change targets

7. No Negative Impact on Irish Wind Industry ●Only 1/3 of gate 3 connections required for 2020 targets ●Development focused on west coast ●Significant portions of inland wind potential that cannot be absorbed onto the Irish system ●Latest technology makes new locations feasible

8. Development Pipeline Onshore Ireland ●Mainstream currently developing large portfolio of onshore wind ●All sites designated ‘suitable for wind ‘ by local county development plans ●Planning Consents by 2015 ●Will feed directly into 2 converter stations ●All Transmission Lines underground

9. 5 GW Direct Export - Offshore & Onshore Mix

10. Following the money ●Annual exports of renewable energy of c. € 1.0 billion ●Investment in power generation of c.€7.5 to € 13.75 billion ●Investment in transmission facilities of c. €6.0 billion

11. State Income: €12.5bn in Revenues ●€12.5bn in tax revenues generated for the State ●€1.4bn by 2020 Note: Above calculation based on the assumption of achieving 1.8 ROCS per MWhr

12. >€900m in Direct Local Benefits ●€900m in rates to Local Authorities over the lifetime of the wind parks ●Local injection of €8.4m annually, per phase ●Significant direct benefits to rural midland communities ●Additional investment through local service

13. Local Direct Employment: 1800 Jobs ●Installation phase: Red ●800 jobs by 2015 ●Operation & Maintenance: Green: 120 lifetime jobs ●Rural ●Long-term (>25yrs) ●Cannot be relocated

14. Job creation ●Irish wind industry generates 1.5 man years of direct employment per MW installed ●The EWEA has estimated that a total of 15.1 man years of employment per megawatt are created ● 1.5 * 5000 = 7,500 man years ●15.1 * 5000 = 75,000 man years ●Mainstream has proposed a more conservative estimate of 8 man years / MW, or 40,000 man years for 5GW ie
