From o1 pro with deep research # Comparison of Power Generation Options ## Upfront Capital Cost - *Nuclear*: Very high (£4,000-6,000/kW), with 10+ year construction time - *Natural Gas (CCGT)*: Low to moderate (£500-1,000/kW), with 2-3 year construction time - *Wind + Battery*: Moderate for turbines (£1,000-1,500/kW) plus substantial battery costs - *Solar + Battery*: Moderate for panels (£800-1,200/kW) plus large battery costs, especially for winter ## Plant Lifespan - *Nuclear*: Typically 60 years, with possible extensions; 2+ builds over 100 years - *Natural Gas*: 25-30 years; requires 3-4 rebuilds over 100 years - *Wind + Battery*: 25 years for turbines, 10-15 years for batteries; multiple replacements needed - *Solar + Battery*: 25-30 years for panels (with declining output), 10-15 years for batteries ## Fuel & Operating Costs - *Nuclear*: Low fuel cost, high operating cost (staffing, maintenance, safety) - *Natural Gas*: Major cost is fuel (price volatility), plus potential carbon costs - *Wind + Battery*: No fuel cost, moderate turbine O&M, plus battery replacement costs - *Solar + Battery*: No fuel cost, low panel O&M, plus battery replacement costs ## Levelized Cost (No subsidies) - *Nuclear*: £90-120/MWh - *Natural Gas*: £50-60/MWh (without carbon cost), £100+/MWh with high carbon prices - *Wind + Battery*: Base wind £40-50/MWh, potentially exceeding £100-150/MWh with storage for 90% CF - *Solar + Battery*: Base solar £40-50/MWh, potentially exceeding £150-200/MWh with storage ## Reliability / Capacity Factor - *Nuclear*: ~90% capacity factor, suited for baseload - *Natural Gas*: 80-90% if run as baseload, highly flexible - *Wind + Battery*: 35-50% raw CF for wind alone, requires battery + overbuild for 90% CF - *Solar + Battery*: 10-15% raw CF in UK, requires massive overbuild and storage for 90% CF ## Key Advantages - *Nuclear*: High-capacity 24/7 baseload, low CO₂, stable long-term output - *Natural Gas*: Low upfront capital, flexible/dispatchable, mature technology - *Wind + Battery*: Carbon-free, potentially low marginal wind cost, lower price volatility - *Solar + Battery*: Carbon-free, low operating costs, suitable for distributed generation ## Key Drawbacks - *Nuclear*: Expensive upfront, complex construction, decommissioning burden - *Natural Gas*: Volatile fuel costs, CO₂ emissions unless carbon capture added - *Wind + Battery*: High cost for baseload reliability, weather-dependent, multiple battery replacements - *Solar + Battery*: Very high overbuild and storage needs for 90% CF, seasonal variation
