Thermal Energy Storage Tank Specification: What to Put in the Document
A thermal energy storage tank specification should state the duty (energy, dT, hours), shell material and coating system, insulation, diffuser performance, foundation scope, applicable standards (AWWA D103-09, ISO 28765), QA requirements and acceptance tests. A clear spec prevents scope gaps and price-only bids.
A thermal energy storage tank specification is the document that makes a project comparable and executable. It must state duty, materials, standards and acceptance clearly.
Technical Explanation
Performance section
· Define shift energy, temperature difference, hours of cover and standby-loss limit so bidders size to the same target.
· Performance, not geometry, should lead the spec.
Materials and standards
· Name the coating system, steel grade, insulation and the governing standards; reference AWWA D103-09 and ISO 28765 where they apply.
· Standards make the spec auditable.
Acceptance
· State hydrostatic test, holiday test, thickness and thermocline-verification requirements so quality is measurable at handover.
· Acceptance turns the spec into proof.

Frequently Asked Questions (FAQ)
Q: What must a TES tank spec include?
A: Duty, materials, standards, QA and acceptance - performance first.
Q: Which standards to reference?
A: AWWA D103-09 for bolted tanks and ISO 28765 for enamel coating where applicable.
Q: Should I specify geometry?
A: State performance; let bidders propose geometry that meets it.
Q: How do I ensure quality?
A: Name the tests - hydrostatic, holiday, thickness, thermocline verification - in acceptance.
Q: Can the spec be too tight?
A: Yes - over-specifying geometry can exclude good solutions; specify outcomes.
Q: Who writes it?
A: The engineer of record, with supplier input on coating and QA.
A thermal energy storage tank specification leads with performance, names materials and standards, and defines acceptance. Clear clauses make the project comparable and the quality provable.
