About the company
Daniel L. Sun, Inc., a woman-owned, minority-owned small business headquartered in San Jose, California, provides software maintenance, development, and enhancement services for the Department of Energy's Western Area Power Administration as a direct prime contractor on sole-source and firm fixed-price purchase orders. The vendor operates exclusively in the full-and-open marketplace with no set-aside designations across its federal footprint, despite its woman-owned and Asian-Pacific American-owned designations qualifying it for WOSB and minority-owned certifications.
The vendor's entire customer base consists of a single federal agency — WAPA accounts for all 31 awards and $3.7 million in combined potential value across the vendor's tracked award history. This extreme concentration reflects a tightly scoped, long-standing technical relationship. Daniel L. Sun, Inc. has held over a dozen purchase orders since 2021 focused on the Interregional Transmission Coordinator Office Application (ITOA), WAPA's critical web-based software platform supporting power transmission operations and planning across the central and western United States. Representative work includes a $110,349 maintenance support renewal through December 2026 (awarded January 1, 2026), a $105,166 annual maintenance renewal for January through December 2025 (awarded January 1, 2025), a $117,963 ITOA Phase 5 enhancements contract (awarded October 1, 2024), and a $54,400 Single Sign-On authentication maintenance support renewal extending to September 23, 2026 (awarded September 19, 2025). Recent 2026 awards include a $27,000 SunNet special work permit module enhancement (awarded September 25, 2026, with completion by September 24, 2027) and a $25,200 SMS substation check-in module implementation (awarded July 31, 2026, completing December 31, 2026).
Work is performed at the vendor's Lakewood, Colorado office and in Denver, Colorado, supporting WAPA's critical energy infrastructure technology systems. Category concentration aligns with the ITOA focus: 22 awards fall under software publishers NAICS, with the balance under other computer-related services. Primary PSC coding centers on IT software and business application software, with some coverage of IT support equipment and software-as-a-service development.
Activity has remained modest and flat — averaging roughly 1.6 awards per year over the past five years, with 2026 showing three awards year to date. Three awards with combined potential value of $163 thousand carry ultimate completion dates within the next twenty-four months, creating modest recompete exposure. The vendor operates as a pure prime contractor (100% of awards) with no subcontract footprint, indicating tight vertical integration or a narrow scope that does not require sub-tier engagement.
