AEP taps Jacobs, WSP for $37B Power transmission buildout. Engineering firms to split regional delivery as utility nearly doubles its transmission rate base and expands its 765-kV network. October 30, 2026 ENR AT-A-GLANCE 5 Things to Know EXPAND American Electric Power has tapped Jacobs and WSP to help deliver a $37-billion transmission investment program across 11 states as the utility prepares to nearly double its transmission rate base by 2031. The appointments were announced Oct. 29, one day after AEP unveiled an expanded $100-billion capital plan for 2027 through 2031. Transmission represents the largest share, ahead of $36 billion planned for generation and approximately $22 billion for distribution. Jacobs will support AEP's seven-state eastern transmission portfolio, with WSP USA handling the four-state western portfolio. Neither firm disclosed its contract value; AEP's $37 billion represents planned systemwide transmission investment, not the value of the two awards. Of that investment, approximately $17 billion is earmarked for projects driven by regional transmission organizations, $11 billion for system reliability and $9 billion for transmission serving individual customers. AEP expects its transmission rate base to rise from approximately $37 billion this year to $69 billion in 2031 and plans to nearly triple the mileage of its 765-kV network, of which it already owns about 90% of the nation's existing lines. Driving much of that expansion is a sharp increase in contracted electricity demand. AEP signed 15 GW of new load commitments during the third quarter and expects incremental contracted load to reach 84 GW by 2031. Of that total, 92% is tied to data centers, including cryptocurrency customers, according to the company's investor presentation. AEP sets regional delivery structure. Jacobs said work under its eastern assignment is already underway and will ramp up as AEP's portfolio grows. Its scope includes project management and controls, engineering and design, siting, public outreach, right-of-way acquisition and environmental services. Jacobs will lead a team that includes consultant ORC (formerly O.R, Colon Associates), GFT (formerly Bannett Flaming TranSystems) and RC Commonwealth. "Our integrated delivery model will help AEP standardize and scale project delivery across its growing portfolio," Jacobs Chair and CEO Bob Pragada said in a statement.

Ask ENR WSP disclosed fewer specifics about its western assignment but said its work could span planning, environmental review, permitting, engineering, program management and project delivery. ENR reported Oct. 20 that the U.S. Energy Dept. finalized a $1.6-billion loan guarantee supporting AEP's planned reconductoring and rebuilding of 5,000 miles of high-voltage transmission lines across five states, part of a $3.56-billion program. Contractors will be selected "on a project-by-project basis," an AEP spokesman told ENR. $5B Ohio project shows scale of buildout. One of the largest projects now included in AEP's transmission plan is an approximately $5-billion, 765-kV build serving SB Energy's planned 10.4-GW data center campus at the former Portsmouth federal gaseous diffusion plant site in Piketon, Ohio. AEP's Piketon Area Improvements Project includes multiple 765-kV transmission routes across southern Ohio to supply a planned data center campus at the former gaseous diffusion plant in Piketon. The map shows proposed and existing transmission corridors connecting the project area with AEP substations near Cheshire and Hanging Rock. AEP says final routes for some segments remain under evaluation and require Ohio Power Siting Board approval.

Construction is expected to begin in the first quarter of 2027, and AEP has secured substantially all required rights-of-way, Fehrman said during the utility's Oct. 28 earnings call. Three planned 765-kV transmission lines would each provide approximately 3.2 GW of incremental capacity, with targeted in-service dates at the end of 2028, 2029 and 2030, according to AEP's Oct. 28 quarterly filing with the U.S. Securities and Exchange Commission. The campus's initial 800 MW of load is expected to be served using existing transmission capacity. The customer will cover project costs through payments extending 20 years after each line enters service. Before the remaining transmission work moves ahead, AEP still needs approvals from regional transmission operator PJM, the Public Utilities Commission of Ohio and the Federal Energy Regulatory Commission.

WSP in Africa brings science, strategy and practical insight to NICOLA 2026. The challenges of moving beyond technical understanding and regulatory compliance to deliver defensible, sustainable environmental outcomes are becoming increasingly complex. Effective decisions require an integrated understanding of environmental systems, long-term risks, commercial realities and the people and processes involved in delivering remediation. At this year's NICOLA Conference, taking place on 28 and 29 October 2026 under the theme, "Connecting Knowledge to Action", WSP in Africa is contributing its multidisciplinary expertise in contaminated land management, remediation and ecosystem restoration, exploring how environmental knowledge can be translated into practical, sustainable outcomes. Bringing together international regulatory perspectives, groundwater science, remediation technologies and real-world project experience, WSP's specialists are sharing insights on managing risk, addressing historic contamination and supporting informed environmental decision-making. Dr Olivier Maurer, global account manager for WSP and NICOLE (Network for Industrially Coordinated Sustainable Land Management in Europe) representative, will deliver a keynote address on day 2, exploring the European Union Soil Monitoring Law and its implications for sustainable remediation worldwide. The legislation represents a significant development in recognising soil health as fundamental to environmental sustainability and food security, establishing common monitoring approaches and risk-based systems for identifying potentially contaminated sites. "The European Union's ambition to achieve healthy soils by 2050 reinforces the importance of treating soil as a finite resource that underpins food security and environmental resilience. These developments offer valuable lessons for Africa as we consider how monitoring, regulation and risk-based approaches can support better long-term outcomes," Dr Maurer explains. Groundwater protection is another central theme in WSP in Africa's programme, with three experts examining how practitioners can interpret environmental data, evaluate remediation options and assess potential impacts with greater confidence. Sarah Skinner, director: Groundwater at WSP in Africa, presented a case study on the feasibility of permeable reactive barriers, a passive technology that treats groundwater contamination as water moves through reactive materials installed underground. Her presentation demonstrated why successful implementation requires more than confirming suitable hydrogeological conditions or laboratory performance. "Remediation decisions need to consider the whole system, not just whether a technology works in principle," she says. "By applying multi-criteria decision analysis, we can identify overlooked risks, account for changing site conditions and make more defensible decisions about whether a permeable reactive barrier is appropriate." Aashna Bissoon, hydrogeologist and groundwater modeller at WSP in Africa, will explore how climatic variability influences groundwater monitoring in a Groundwater Management Unit in South Africa's Northern Cape. By combining statistical analysis, rainfall records and conceptual hydrogeological modelling, the study demonstrates that groundwater responses vary across locations, even under the same regional climatic conditions. She emphasises that groundwater monitoring data needs to be interpreted in context. "Understanding the relationship between rainfall, aquifer characteristics and longer term groundwater behaviour helps us distinguish natural variability from potentially significant environmental changes," she says. "This strengthens risk assessments and supports evidence-based decisions, particularly in water-stressed environments." Camille Kraak, principal associate: Groundwater at WSP in Africa, will present an assessment of the transition from open-pit to underground mining at a southern African operation. Integrating three-dimensional groundwater flow and contaminant transport modelling with geochemical assessment, her study evaluates potential impacts during the mine's operational life and after closure. "Predictive groundwater modelling enables us to move beyond qualitative assessments and evaluate potential contaminant pathways under different conditions," she says. "Understanding how geology, groundwater connectivity and contaminant sources interact provides a stronger technical basis for mine design and closure planning, while addressing stakeholder concerns about protecting surrounding water resources." Governance, procurement and communication challenges can prevent technical knowledge from translating into effective environmental outcomes. Adam Sanderson, director: Geochemistry at WSP in Africa, and Heidi Snyman, strategic technical adviser for WSP in Africa and NICOLA representative, will form part of a dialogue-based examination of a contaminated land investigation, following the project from inception to final reporting. Their presentation explores how misaligned procurement requirements, appointment delays, access constraints, limited budgets and resource pressures can undermine project delivery, data quality and decision-making. "South Africa has extensive environmental regulation and technical guidance, yet implementation remains challenging when communication and governance processes fail. Understanding the pressures experienced by clients, consultants and regulators is essential if we are to improve collaboration and deliver safer, more effective environmental outcomes," says Sanderson. Snyman adds: "The gap between knowledge and action is not always a technical problem. Project outcomes are also shaped by procurement decisions, institutional processes, competing expectations and the time available for critical thinking. Recognising these constraints can help stakeholders work together more constructively and make better informed decisions." WSP's team of experts seeks to highlight a common principle at the conference: Sustainable remediation depends on integrating scientific evidence with practical experience, sound governance and a clear understanding of long-term environmental risk. At NICOLA 2026, WSP in Africa will contribute to the sector's collective effort to turn insight into action, supporting more informed decisions that protect soil and groundwater resources while delivering sustainable remedial outcomes.
