Performance Overview Comparison

The following tables summarize the key comparisons between different technologies in the power sector under given assumptions:

Metric	Traditional Combined Cycle Gas Turbine (CCGT)	Utility-Scale PV Solar
Short-Term Cost (per MWh)	$35–$45	$25–$35
Long-Term Cost (per MWh)	$90–$120	$60–$90
Additional Cost for Storage	~$15–$20 per MWh for grid-scale integration	~$40–$50 per MWh when paired with storage

Input Cost (per MWh)	Gas<br>$30–$45	Coal<br>$70–$85
Manufacturing/Operational	$10–$15	$5–$10

— Costs shown reflect production expenses, but omit system-level costs (e.g., transmission, curtailment). For example, solar requires additional grid investments to offset variability, which may not be reflected in the above costs.

Solar + Storage vs. Displacement Costs

Category	Baseline Displacement	Solar + Storage Impact
Peak Demand (7 PM)	75% displacement	0% displacement
Hourly Production	405 GWh	460 GWh

— Storage increases production by 55 GWh during peak hours, effectively delaying demand and boosting overall system capacity.

Value-Added Generation Cost Analysis

Analysis Type	Standard Cost per MWh	Adjusted Cost per MWh
Levelized Cost of Avoided Electricity (LCOAv)	Base Case: $70–$90	Value-Adjusted: $120–$140 (includes firming costs)

Observation: While alternative metrics provide improved analytical frameworks, they also prove insufficient in capturing comprehensive system dynamics. Value-assessment studies remain essential for robust power system planning, particularly in regions with complex grid conditions.

Distribution by Implementation Method

Deployment Type	Success Rate	Plan Completion Rate	Operational Efficiency
Storage Systems	90%	88%	75%
Grid Integration	75%	91%	72%

Analysis: Grid integration projects show better planning and higher implementation rates than standalone storage systems. However, operational reliability lags when challenges with infrastructure scale escalate during phases of decarbonization transitions.
