• •
Major ways of efficiency improvements in Russia
Expected construction of substantial number of CCGTs (efficiency ~ 50-58%) Still old gas and coal generation (efficiency ~ 30-40%) remain dominating with additional potential for improvement: o
Modernization
o
Environmental improvements, especially for coal
o
Operational efficiency

Enel OGK-5 strategy for efficiency improvements
Coal-fired power plants Gas – fired power plants • • Konakovskaya GRES (2,5 GW): Relatively new plant Half capacity utilized due to competitive market and gas supply limitations • • • Reftinskaya GRES (3,8 GW): Important base load plant Reliability issues Substantial environmental impact • • •
Sredneuralskaya GRES
(1,2 + 0,4 GW CCGT): Oldest plant in the portfolio Worn-out equipment Good market position • •
GRES (1,3 + 0,4GW CCGT): Relatively old plant Good market position
Enel OGK-5 focus on efficiency
1. Construction of new CCGTs (Sredneuralskaya and Nevinnomysskaya PPs) 2. Modernization (Reftinskaya PP) 3. Environmental investments (Reftinskaya PP) 4. Operational improvements (all PPs) 3
1. Construction of new CCGTs: Sredneuralskaya Power Plant Initial situation:
• Oldest plant in the portfolio – first unit commissioned in 1936 • Location – Sverdlovsk region, solid demand and good market position • Mandatory investment in CCGT supported by high capacity tariff from DPM scheme
New CCGT 410 MW:
• • • • Efficiency ~ 57% NOx emissions: ≤ 50 mg/Nm3 Commisioning: Q3 2011 Cost ~ 380 mln EUR

1. Construction of new CCGTs: Nevinnomysskaya Power Plant Initial situation:
• Relatively old plant– first unit commissioned in 1960 • Location – Stavropol region, good market position • Mandatory investment in CCGT supported by high capacity tariff from DPM scheme
New CCGT 410 MW:
• • • • Efficiency ~ 57% NOx emissions: ≤ 50 mg/Nm3 Commissioning: Q3 2011 Cost ~ 400 mln EUR 5
2. Modernization: Reftinskaya Power Plant Initial situation:
• Largest coal power plant in Russia • Location Sverdlovsk region, base load, high importance for Urals market, competitive fuel • Substantial problems for availability and environment

• • •
Reconstruction and modernization of 5 units of 300 MW:
Investment rationale: o o o availability increase around 10% Capacity increase by 8% (from 300 to 325 MW) Specific heat consumption decrease of 15 g/kWh Implementation: 2010 - 2021 years Cost ~ 500-750 mln EUR 6
3. Environmental investments: Bag filters installation at Reftinskaya Power Plant
• • • • •
Replacement of electrostatic precipitators with bag filters:
First time in Russia NOx emissions reduction by 30% Ash emissions reduction of 98% Implementation: 2010 - 2021 years Cost included in the cost of modernization 7
3. Environmental investments: Dry Ash Removal System at Reftinskaya Power Plant Initial situation:
• Serious pollution problems with current wet ash removal system • Substantial problems with ash storage as current ash lagoon capacity is almost exhausted • • • •
Construction of a Dry Ash Removal System
First time in Russia Modern automated and environmentally friendly system for collection, transportation, storage and reutilization of ash Implementation: 2010 – 2012 Cost ~ 250 mln EUR 8
4. Constant improvement of operations contribute to overall efficiency improvements relevant for all PP Heat rate reduction Water consumption reduction Achieved improvements
(2010 vs. 2008) ~ 0,5% (1,4 gce/kWh)* • • •
Examples of measures implemented
Ball cleaning system More precise O2 meters Energy saving lamps ~ 10% (20 m3/MWh)* • Water meters
Increasing of availability
~ 5%* • • Replacement of heating surfaces SMED planning for planned outages Use: Confidential • • • Project office to track existing and scan for additional initiatives “Zenith” brand and quality program introduced for all efficiency improvements Improvement ideas coming also from sharing “best practice” with other Enel assets * best result among all power plants 9
4. Enel introduced a “Zenith” brand for operational improvements worldwide Maximum performance
•
Become the benchmark in terms of operating excellence in the power and gas industry
•
In all geographies (Italia, Spain, Slovak Rep., Romania, Russia, …)
•
In all the divisions and staff functions In all the Group Across all levers
•
Leveraging all possible levers (Margin, Opex, Capex, Working Capital)
•
Maximizing pre-tax cash flow generation
• •
Creating a top performance culture Developing a group of people in charge to drive change
•
Fostering experience sharing, through dissemination of knowledge and of management best practices across the group Developing our people, skills and knowledge
