Hidden Costs of Gas Plants Add 30% to Project Expenses

⚡ AI Executive Summary

Regulatory reviews of proposed gas-fired power plants frequently overlook critical ancillary expenses related to pipeline infrastructure, fuel supply chains, and operational storage requirements. These often-excluded costs can substantially increase the actual capital and operational burden compared to the headline project cost. For grid planners and utility regulators, this analytical gap has significant implications for economic dispatch decisions, generation adequacy planning, and long-term infrastructure investment. Underestimating the true delivered cost of gas generation can distort resource procurement decisions, favoring inefficient incumbent technologies over renewables and storage alternatives that may deliver better value over project lifetimes. GridLab's analysis underscores the need for comprehensive cost accounting in regulatory proceedings to ensure that generation resource comparisons reflect complete, integrated system costs rather than isolated plant economics.
