Capital Expenditures
Growth Capital Expenditures. The majority of our growth capital expenditures are related to the acquisition cost of new compressors when our idle equipment cannot be reconfigured to economically fulfill a project’s requirements and the new compressor is expected to generate economic returns that exceed our cost of capital over the compressor’s expected useful life. In addition to newly-acquired compressors, growth capital expenditures include the upgrading of major components on an existing compression package where the current configuration of the compression package is no longer in demand and the compressor is not likely to return to an operating status without the capital expenditures. These expenditures substantially modify the operating parameters of the compression package such that it can be used in applications for which it previously was not suited.
Maintenance Capital Expenditures. Maintenance capital expenditures are related to major overhauls of significant components of a compression package, such as the engine, compressor and cooler, which return the components to a like-new condition, but do not modify the application for which the compression package was designed.
Projected Capital Expenditures. We currently plan to spend approximately $230 million to $235 million in capital expenditures during 2022, primarily consisting of approximately $150 million for growth capital expenditures and approximately $70 million to $75 million for maintenance capital expenditures. We anticipate increased 2022 capital expenditures, particularly growth capital expenditures, as compared to 2021 due to increased investment in new compression equipment as a result of higher customer demand.
