Risk Factors Full Breakdown - Total Risks 35
- Manufacturing - Risk 1SINGLE TRANSPORTATION PIPELINE RISK. NW Natural relies on a single pipeline company for the transportation of gas to its service territory, a disruption, limitation, or inadequacy of which could adversely impact its ability to meet customers' gas requirements, which could significantly and negatively impact NW Holdings' and NW Natural's results of operations.
NW Natural's distribution system is directly connected to a single interstate pipeline, which is owned and operated by Northwest Pipeline. The pipeline's gas flows are bi-directional, transporting gas into the Portland metropolitan market from two directions: (1) the north, which brings supplies from the British Columbia and Alberta supply basins; and (2) the east, which brings supplies from the Alberta and the U.S. Rocky Mountain supply basins. If there is a rupture or inadequate capacity in, or supplies to maintain adequate pressures in, the pipeline, NW Natural may not be able to meet its customers' gas requirements and we would likely incur costs associated with actions necessary to mitigate service disruptions, both of which could significantly and negatively impact NW Holdings' and NW Natural's results of operations.
- Manufacturing - Risk 2BUSINESS DEVELOPMENT RISK. NW Holdings' and NW Natural's business development projects may not be successful or may encounter unanticipated obstacles, costs, changes or delays that could result in a project being unsuccessful or becoming impaired, which could negatively impact NW Holdings' or NW Natural's financial condition, results of operations and cash flows.
Business development projects involve many risks. We have recently or are currently engaged in several business development projects, including, but not limited to, several gas, gas storage, water, wastewater, water services and RNG projects, non-regulated investments in RNG projects, and purchasing, marketing and reselling of RNG and its associated attributes. We may also engage in other business development projects such as investments in additional long-term gas reserves, gas storage projects, CNG refueling stations, power to gas, power generation, hydrogen projects, carbon capture projects, geothermal projects or other similar projects. For example, we are currently planning an approximately 4-5 Bcf expansion of our North Mist gas storage facility. This expansion is subject to certain conditions including the customers' final approval of project costs and notice to proceed, as well as the receipt of required permits and authorizations. If these approvals are delayed or not obtained, we may not achieve the benefits of the project on our expected timeline or at all. Moreover, all of our business development activities are subject to uncertainties and changed circumstances and may not reach the scale expected, be successful or perform as anticipated. Additionally, we may not be able to obtain required governmental permits and approvals to complete our projects in a cost-efficient or timely manner, potentially resulting in delays or abandonment of the projects. We could also experience issues such as: technological challenges; ineffective scalability; failure to achieve expected outcomes; unsuccessful business models; startup and construction delays; construction cost overruns; challenges in attracting customers or partners or increased competition for new projects; reliance on or inability to direct third parties; disputes with contractors or other third parties; the inability to negotiate acceptable agreements such as rights-of-way, easements, construction, gas supply or other material contracts; failure or delay in receiving applicable permits; changes in customer demand, perception or commitment; public opposition to projects; changes in market conditions; marketing risk and changes in market regulation, behavior or prices, market volatility or unavailability, including markets for RNG and its associated attributes or other environmental attributes; the inability to receive expected tax or regulatory treatment (including any applicable tax incentives or credits for renewable fuels); and operating cost increases. Additionally, we may be unable to finance our business development projects at acceptable costs or within a scheduled time frame necessary for completing the project. Any of the foregoing risks, if realized, could result in business development efforts failing to produce expected financial results and the project investment becoming impaired, and such failure or impairment could have an adverse effect on NW Holdings' or NW Natural's financial condition and results of operations.
- Manufacturing - Risk 3OPERATING RISK. Transportation, storage and distribution of gas and liquid fuels, as well as water and wastewater, involves numerous risks that may result in accidents and other operating risks and costs, which may not be fully covered by insurance, and which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows.
NW Holdings and NW Natural are subject to all of the risks and hazards inherent in the businesses of gas and liquid transmission, distribution and storage, water distribution, and water and wastewater services including: - earthquakes, wildfires, floods, storms, freezes, landslides, hurricanes, and other severe weather incidents and natural hazards;- leaks or losses of gases or liquids, or contamination of gases or liquids by chemicals or compounds, as a result of the malfunction of equipment or facilities or otherwise;- operator errors or damages from third parties;- negative performance by our storage reservoirs, facilities, or wells that could cause us to fail to meet expected or forecasted operational levels or contractual commitments to our customers or other third parties;- problems maintaining, or the malfunction of, pipelines, biodigester facilities, wellbores and related equipment and facilities that form a part of the infrastructure that is critical to the operation of our facilities;- presence of chemicals or other compounds in the gases or liquids we deliver that could adversely affect the performance of the system or end-use equipment;- failure of gas or water storage reservoirs;- inadequate supplies of RNG, natural gas or water or contamination of water supplies;- operating costs that are substantially higher than expected;- higher maintenance costs or service disruption due to the need to replace or repair aging infrastructure;- failure to secure or maintain necessary rights-of-way, easements, property rights, permits and other rights necessary to operate or business or complete projects;- supply chain disruptions, including unexpected price increases, or supply restrictions beyond the control of our suppliers;- migration of gas through faults in the rock or to some area of the reservoir where existing wells cannot drain the gas effectively, resulting in loss of the gas;- blowouts (uncontrolled escapes of gas from a pipeline or well) or other accidents, fires and explosions; and - risks and hazards inherent in the drilling operations associated with the development of gas storage facilities, and wells. For example, TC Pipelines, LP (TC Pipelines) previously identified the presence of a chemical substance, dithiazine, at several facilities on the system of its subsidiary, Gas Transmission Northwest (GTN), and those of some upstream and downstream connecting pipeline facilities. A portion of NW Natural's gas supplies from Canada are transported on GTN's pipelines. TC Pipelines has reported that dithiazine can drop out of gas streams in a powdery form at some points of pressure reduction (for example, at a regulator), and that significant accumulations may impair equipment performance, potentially increasing preventive and corrective maintenance costs. Although NW Natural has not detected significant quantities of dithiazine on its system to date, we continue to monitor for its presence and could in the future identify increased levels of dithiazine or other compounds that may adversely affect system performance or end-use equipment. These and other operational risks could result in disruption of service, personal injury or loss of human life, damage to and destruction of property and equipment, pollution or other environmental damage, breaches of our contractual commitments, and may result in curtailment or suspension of operations, which in turn could lead to significant costs and lost revenues. Further, because our pipeline, storage and distribution facilities are in or near populated areas any loss of human life or property or adverse financial outcomes resulting from such events could be significant. We could be subject to lawsuits, claims, and criminal and civil enforcement actions. Additionally, we may not be able to maintain desired levels of insurance, and the insurance coverage we do obtain may contain large deductibles or fail to cover certain hazards or cover all potential losses, which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows.
