Plant Maintenance Standards Affecting the Utilities Industry

The utilities industry maintains their plants and plant equipment and leverages the same standards that have been developed in the more traditional manufacturing industries.  Below are the standards that affect plant operations and maintenance that affect the Utilities industry.

Business To Manufacturing Markup Language (B2MML)  

ISA-95 standard defines the terminology and models used in the integration of business systems at the enterprise level with control systems at the plant floor level. The standard also defines a set of different operations that should be supported by intermediate MES (Manufacturing Execution System) systems.
B2MML is an XML implementation of the ANSI/ISA 95 family of standards (ISA-95), known internationally as IEC/ISO 62264. Companies interested in following ISA-95 for integration projects may use B2MML to integrate business systems such as ERP and supply chain management systems with manufacturing systems such as control systems and manufacturing execution systems. B2MML is a complete implementation of ISA-95 as documented in the completeness, compliance and conformance statement which is part of the B2MML download.


The Machinery Information Management Open Systems Alliance is MIMOSA is a not-for-profit trade association dedicated to developing and encouraging the adoption of open information standards for Operations and Maintenance in manufacturing, fleet, and facility environments. MIMOSA specifications enable collaborative asset lifecycle management in both commercial and military applications. In addition to its broad spectrum of international manufacturing company members, defense organizations such as the US Army Product Manager for Test, Measurement & Diagnostic Equipment and the US Navy Total Open Ship Architecture Implementation Program Team actively participate in developing the MIMOSA standards.


The Open Applications Group, Inc. (OAGi) is a not-for-profit open standards organization that defines process-based XML standards called "Business Objects Documents" (BODs) that span both B2B and A2A integration scenarios. The Open Applications Group was formed in late 1994 as one of the first post-EDI organizations focusing on improving the state of application integration. Today, OAGi has defined more than 400 BODs that address a wide variety of business and manufacturing applications. OAGi is currently leading a convergence effort around plant maintenance and operations including ISA-95, B2MML, MIMOSA and WBF.
