Key findings
4
• A renewable revolution is under way
• Dramatic cost reductions for Solar PV, onshore wind
competitive at best sites, CSP has great potential,
hydropower and biomass more mature
• Renewable now THE economic solution for electrification
and often grid extension, increasingly competitive for grid
supply.
• Emerging market manufacturers driving down prices
• Data collection poses challenges
Framework forBiomass, CSP, Hydro, PV & Wind
5
Where to set the boundaries?
Are costs even available? Prices, or price indicators?
Levelised cost of electricity (LCOE)
Emerging issues for O&M?
• Operation and maintenance cost can account for a
substantial share of LCOE
• Why such wide ranges?
• Can all markets move to best practice?
• Cost reduction potential less well understood?
• Reasons for differences in bottom-up engineering cost
estimates and real world project costs not well understood
• O&M issues deserves more attention

Future work: Analysis and data collection
18
• Costing work is vital for support of renewables
• Cost data should have same status as basic statistics!
• Work with companies, industry associations, etc. on data
collection and comparability
• Look at emerging issues, O&M, BoS costs, engineering vs. Real
world project costs, etc.
• Develop web-based tool to allow upload of data, provide
benchmarking details for participants
Wind is beginning to deliver on its large potential, but more needs to be done…
