Darron Farmer

Gas Scheduling Analyst at Enron North America who managed daily nominations for major power generators including Calpine, TXU Energy, and Duke Energy.

Darron Farmer

Darron (Daren) J. Farmer was a Gas Scheduling Analyst in Enron North America’s Texas Gas Operations team, responsible for managing daily gas nominations and scheduling for major power generation customers. Working under Brenda Herod in the Texas trading region operations group, Farmer coordinated fuel supply logistics for companies including Calpine, TXU Energy, and Duke Energy while also overseeing wellhead production management across multiple Texas production areas. His work represented the critical operational infrastructure that ensured physical gas flowed reliably to Enron’s counterparties each day.

Farmer’s email archive in the Enron corpus contains 21,900 messages, making it the sixth largest by volume overall, with 772 unique senders. This substantial correspondence documents his role at the center of Enron’s Texas gas scheduling operations from 1999 through mid-2001.

Career at Enron

Texas Gas Operations

Farmer worked within the Texas trading region operations team that supported several key Enron assets and operations. According to a May 2000 organizational announcement from Brenda Herod, this team provided operational support for the Texas trading region, Bammel Storage Facility, Houston Pipeline (HPL), Powder River Gathering, and Bridgeline. The announcement noted that Risk Management, Deal Validation, and Operational Analysis functions were being combined under Business Controller Steve Venturatos, while Transportation Management under Mary Smith remained separate due to its distinct day-to-day operational requirements.

Farmer was based at Enron’s Houston headquarters, at the heart of the company’s physical gas operations. Company systems used an alternate spelling of his first name (“Daren”).

Reporting Structure

Farmer reported to Brenda F. Herod, who served as Director of Texas Gas Operations. This positioned him within the Energy Services and Operations division under Sally Beck’s broader oversight of Risk Management Operations. The Texas operations team functioned as a critical support unit for Enron’s gas trading activities, handling the logistical execution that followed trading desk decisions.

Gas Scheduling and Nominations

Calpine Power Plants

Farmer’s most visible operational responsibility was managing daily gas nominations for Calpine’s power generation facilities. His archive contains over 1,159 emails with “Calpine Daily Gas Nomination” as the subject. Ricky Archer at Calpine served as the primary external contact, sending 1,390 emails to Farmer over the course of their correspondence.

Traders would establish supply agreements, and schedulers like Farmer ensured the physical commodity reached customers according to their daily requirements. Power plants operate on strict fuel schedules, making this coordination critical to both Calpine’s operations and Enron’s reliability as a supplier.

TXU Energy

TXU Energy represented Farmer’s second major external relationship, with Melissa Jones sending 1,762 emails, the highest volume from any single correspondent in his archive. Additional regular contacts at TXU included Tim Powell, David Avila, Charlie Stone, and Gary Green. Farmer handled gas supply scheduling for TXU’s power generation fleet, coordinating nominations and managing the ongoing relationship between Enron and one of Texas’s largest utilities.

Duke Energy

Farmer also coordinated with Duke Energy representatives Marta K. Henderson and Bruce McMills on gas nominations and scheduling. While smaller in email volume than the Calpine and TXU relationships, Duke represented another significant counterparty in Farmer’s daily operational workflow.

Wellhead and Production Management

Beyond scheduling for power plant customers, Farmer managed physical gas purchases and production scheduling from various wellhead locations across Texas. This responsibility required tracking production estimates, meter readings, and allocation issues across multiple production areas.

Key Production Areas

Farmer’s operational scope included Basin Production (GA 213, Galveston area), Saxet Canales into King Ranch, North Padre Island (meter 883), and interests from Spinnaker, Ranger, and Houston Exploration. He managed multiple HPL (Houston Pipeline) meters across Texas, coordinating the flow of gas from production sites into the pipeline network.

Operational Coordination

Working with the Producer Services group, particularly Vance Taylor and Robert Cotten, Farmer evaluated whether gas would flow and at what price for bidweek position management, the monthly process through which gas marketers established forward commitments. He also handled allocation exceptions and balancing issues that arose when actual production volumes differed from nominations.

Tenaska IV Deal Management

The Tenaska IV power plant supply arrangement represented one of Farmer’s most complex ongoing responsibilities. This structured deal involved managing gas supply to Tenaska IV (Cleburne Plant) while coordinating sales to Brazos Electric and cash forwarding back to Tenaska.

Deal Structure and Financial Scale

The Tenaska arrangement required monthly settlement adjustments and demand fee calculations involving substantial sums. February 2001 settlements totaled $1,143,484.53 forwarded to Tenaska IV, while January 2001 settlements totaled $3,830,131.18. Monthly demand fees ranged from one to four million dollars, requiring careful tracking and adjustment.

Farmer coordinated with Megan Parker in settlements on the complex netting calculations these arrangements required. Deal tickets in the Sitara system (including deals 529856, 384258, 514353, and 452475) documented the various components of the Tenaska relationship.

Deal Ticket Management

The operational nature of this work involved modifying deal tickets based on actual volumes versus nominations, updating demand fees and transportation charges, and coordinating invoice corrections. While the financial scale was significant, Farmer’s role remained administrative and operational rather than trading or structuring focused.

Systems and Technical Expertise

Farmer worked extensively with Enron’s trading and operations systems. POPS (Pipeline Operations System) served as his primary scheduling and nomination platform, while Sitara handled deal entry and trading documentation. He also attended Unify meetings as part of the enterprise system implementation.

His technical knowledge encompassed Houston Pipeline operations and meter management, gas balancing and allocation procedures, transportation contracts and tariffs, wellhead operations and production forecasting, demand charge calculations, pipeline capacity management, and intraday scheduling changes. He served as a key resource for the operational execution of gas trading activities.

Key Correspondents

Farmer worked at the intersection of external counterparties and internal operations teams.

Name Messages Position
Melissa Jones (TXU) 1,762 External - TXU Energy Scheduler
Ricky Archer (Calpine) 1,390 External - Calpine Nominations
Ami Chokshi 818 Trading Support/Risk Management
Robert Cotten 412 Producer Services/Wellhead Operations
Mary Poorman 396 Volume Management/Balancing

Robert E. Lloyd 268 Operations
Mark McCoy 258 Operations
Lee Papayoti 232 Operations
Megan Parker 198 Settlements
Brenda F. Herod 174 Director, Texas Gas Operations

Farmer maintained intensive external communication with major counterparties (TXU, Calpine) and regular internal coordination with operations colleagues handling volume management, settlements, and wellhead production.

Work Style

Farmer’s email correspondence was action-oriented. His messages often consisted of brief, direct responses, frequently signed simply with “D.” Responses like “done” or “I’ve changed the deal” focused on execution and task completion rather than lengthy discussion.

Some personal emails indicate participation in company social activities, including basketball at the YMCA, where he declined Wednesday night games. These glimpses of work-life balance were unusual in his otherwise operations-focused correspondence.

Email Activity

Farmer’s email volume patterns reveal his peak operational period and subsequent decline.

Period Monthly Emails Context
2000 Annual ~18,000 Peak operational period
June 2000 2,107 Highest monthly volume
January 2001 1,100 Active operations
April 2001 700 Continued activity
May 2001 429 Beginning of decline
June 2001 219 Sharp drop
July 2001+ <100 Minimal activity

Email activity declined dramatically beginning May 2001, well before the company’s collapse in late 2001. No specific announcement or explanation for this transition appears in the available email record.

Darron Farmer was not charged in connection with the Enron scandal. His operational role focused on gas scheduling and logistics rather than the financial reporting, accounting, or trading manipulation activities that became the focus of criminal and regulatory investigations.

The email record shows standard gas scheduling activities without indicators of fraudulent activity or market manipulation. External counterparties in his correspondence were legitimate utilities and power generators, and the Tenaska deals appear to be standard tolling and supply arrangements. While Farmer’s deal entry responsibilities gave him access to modify transactions in Enron’s systems, the modifications documented in his emails appear to be legitimate settlement adjustments reflecting actual versus nominated volumes.
