Our Services

 

System Design

PLM has specified and designed many substation, transmission line and distribution projects. We have experience in both turnkey EPC projects and traditional Design - Bid - Build projects. We are recognized for providing a well thought out, cost effective design that meets all client requirements. Our detailed design package often results in limited or no contractor change orders during the construction process.

 

Protection & Control

The PLM staff has evaluated, designed and implemented relay and control protection schemes for generation, substation, distribution and transmission facilities for voltages ranging from 208V to 345,000V. This work has also included development of detailed protective relay settings. PLM also has extensive experience conducting short circuit and coordination studies for utilities, transportation agencies and industrial facilities.

Planning

PLM has performed dozens of system planning studies. Each study begins with an agreed upon System Design Criteria, that sets forth the client requirements and expectations. In addition to cost, external factors, such as permitting requirements, interconnection requirements, aesthetic impacts, etc. are always considered when developing alternative plans and making final recommendations.
 

Power Supply & Rates

PLM manages more than 900 MW of load for utility clients throughout the northeast (NYISO and ISO NE) energy markets. We provide both long run power supply planning and daily bid-to-bill services on behalf of a wide array of municipal electric utilities that are market participants of the Independent System Operator of New England (ISO-NE) and direct customers of the New York Independent System Operator (NYISO). Bid-to-bill services include hourly load forecasting, resource optimization and scheduling of transactions to clients in the NYISO. PLM also provides invoice verification services to its clients that are ISO-NE participants as well as direct customers of the NYISO.

NERC Compliance

PLM has developed comprehensive NERC compliance plans for utilities in the NPCC footprint from the ground up with the functional registration of Transmission Owner, Distribution Provider and Load Serving Entity. PLM successfully guided clients through the challenges of the revised functional registration criteria and the revised Bulk Electric System definition. PLM has guided its clients through several off site NERC Audits, self-reports and guided self-certifications.

 

Additional Services

PLM provides many services outside of the traditional substation, transmission & rates. We have provided detailed training programs for field personnel on the operation of their protection systems. Some of the other various services we provide include: operation/mis-operation investigation, owner's engineer, and regulatory compliance.

Staff

The PLM staffing policy is to seek out and retain industry experts and put them directly in charge of meeting our clients needs. This approach is based on a proven philosophy that these knowledgeable and efficient professionals actually provide a higher level of value to our clients when compared to larger, more traditional firms that often have less experienced staffs and multiple layers of management.

Quality is remembered long after the price is forgotten. PLM's emphasis on quality staffing provides valuable benefits. Engineers are constantly bouncing ideas off one another, optimizing solutions and refining concepts in order to provide a consistent quality product.
