Rate Schedules & Tariff Analysis
WSTE's C&I rate design follows a standard cooperative structure: a fixed monthly customer/facility charge, a demand charge per kW for larger accounts, and a per-kWh energy charge, all overlaid with monthly Power Cost Adjustment and Fuel Cost Adjustment riders that pass through wholesale power costs. Because WSTE buys 100% of its power wholesale, the PCA/FCA is the primary driver of bill variability. WSTE does not publish specific $ figures online; its average bundled residential rate (~10.87 cents/kWh) is well below the national average, suggesting competitive C&I energy pricing.

Washington-St. Tammany Electric Cooperative Data Access FAQ
Can my energy consultant pull WSTE usage data directly via API?▾
No. WSTE does not offer a public API or Green Button Connect My Data (OAuth). The supported path is customer-mediated: the member downloads a Green Button ESPI XML file (up to 14 months) from SmartHub and shares it with the consultant, who imports it into a compatible analysis tool.
What interval granularity is available for a commercial account?▾
WSTE's AMI meters report roughly 15-30 minute interval data in SmartHub, with up to 14 months exportable via Green Button DMD. There is no real-time streaming feed for third parties.
How does a third party get authorized for billing data?▾
The member signs an authorization letter naming the third party, which is submitted to the WSTE Billing Supervisor. WSTE may then provide historical billing data by email or mail after verification. Processing time is variable; there is no self-service portal.
Can WSTE commercial customers choose a competitive electricity supplier?▾
No. WSTE is a member-owned cooperative in vertically integrated, LPSC-regulated Louisiana. There is no retail supplier choice; C&I members take service under WSTE's published rate schedules.
Is EDI available for large commercial accounts?▾
No documented EDI program exists for retail suppliers or consultants. For any future automated exchange, contact the WSTE IT Supervisor; any solution would be coordinated through NISC and would likely use ANSI X12.
