•Sep. 2008, RPS clarified - Green Energy Strategy
•Dec. 2008, RPS adopted- The 3rd Renewable Energy Plan
•Mar. 2010, Korean National Assembly passed the RPS bill
•Jan. 2012 RPS takes effect

RPS Calculation

•RPS Mandatory Volume = Mandatory supplier fossil fuel power generation volume X yearly RPS mandatory ratio
•RPS Power Generation Volume = New renewable energy source power generation volume X REC
•RPS Penalty = (RPS Mandatory Volume – RPS Power Generation) X 40 (Korean Won) (=3.4 cents)/kWh X 150%

Biomass New Renewable Energy Power Generation
New renewable energy source applied for RPS
Classification RPS applied source RPS not applicable
Power plant usage available
Wood pellets, wood chips, RDF, RPF, TDF
Bituminous coal, anthracite coal
Power plant usage not available
PKS, EFB, rice husks Natural waste
9
Biomass New Renewable Energy Power Generation
Dual fuel available source upon the type of boiler
Classification Pulverized boiler Circulating fluidized bed combustion
Dual fuel available Wood pellet, DFB, Rice husks pellet
Wood pellet, EFB, rice husks pellet, PKS, wood chip
Dual fuel not available PKS, wood chip
10
Biomass New Renewable Energy Power Generation
Projection on wood pellet usage (pulverized boiler: 3% dual fueling assumption) :
Coal consumption volume 90M ton x dual fueling ration 3% x (bituminous coal 6,000/pellet 4,500) = 3.6M / year
Woodpellet 1ton = 2,000 kWh in power generation
Co-firing: 2,000 kWh/ton x 1.0 = 2,000 kWh/ton in RPS
Full firing: 2,000kWh/ton x 1.5 = 3,000 kWh/ton in RPS
(co-firint biomass:1.0/ full firing biomass:1.5)

Preparation of Biomass by GencoGenco A
Plan to co-firing in fluidizing bed boiler (200MW x2) as of 2012: 10% wood chip or /and pellet, 150,000 ton/year
Construction of full biomass powr plant (30MW x 2) is in progress: wood chip, 180,000ton/year
Genco B
Construction of fluidizing bed boiler (500MW x2) for co-firing with pellet will be completed:
5% pellet, 400,000ton/year
Genco C
Commission of fluidizing bed boiler (340MW x1) for co-firing with pellet is in progress:
5-10% pellet, 300,000ton/year
15
Preparation of Biomass by GencoGenco A, B, C, D, E
Review of co-firing with pellet in pulverized coal boiler
Capacity: each of 500MWx8 units, 5 companies
Usage of coal by Genco in 2010: 80 million ton/year
Expected rate of co-firing with biomass: 3-5%
Combined Heat & Power Plant (CHP)
Usage of wood chip by CHP boiler: 600,000ton/year
CHPs are used in paper mills, dye houses & chemical plant with heat
If price terms are satisfactory, CHPs are to use biomass

Genco’s consideration on BiomassRelative competitiveness of biomass• Cost on production & transportation
• Long-term supply capability
• Legal consideration:
biomass is usable in power plant, but PKS,. EFB, rice husk are not allowed for power plant because they are categorized as wastes
July 2012, Min. Env. Will review the current categorization
• Technological concerns: tube corrosion, slagging, effect of boiler combustion should be reviewed
• Handling issues: facility of unloading, storage, conveyor systems
