Client Name: City of Santa Ana I AMI FEASIBILITY REPORT 11.1.4 Design, Build, Operate, and Transfer The design, build, operate and transfer (DBOT) approach consists of the outsourcing of the majority of planning, design, and implementation work to a general contractor (e.g., project or systems integrator perhaps). The utility or its agent would participate in ensuring the requirements of the AMI system meet the organizations business needs, but the operations and management oversight of the project, including the project management office, implementation team, and work and deployment tasks, would all be the responsibility of the general contractor. 11.1.5 Managed Service Managed Service approach consists of traditional Software as a Service (SaaS) approach where the vendor will host and manage the network, AMI HES and MDMS. Utility will manage the project and work with the vendors/partners. System integration at the utility end (billing system, work management system etc.) would be done by the utility or system integrator. The vendor would manage the integrations for AMI and MDMS. Meter deployment can be done by the utility and/or AMI vendor (or contractor). Utility will have access to systems and data hosted by the vendor to enable business operations, reporting and analytics. Managed service offers the benefit of less initial capital investment in hardware and software, quick start up, no need for skilled resources to manage AMI HES, MDMS and network, and the utility can focus on the core business rather than managing network and new systems. Black & Veatch's experience is that few utilities are currently pursuing the utility implemented or utility led approach. The resources required to manage a major AMI project as well as having staff on hand that are experienced and well versed in AMI project issues is rare. The use of a project implementer to act on the utility's behalf in the implementation of the AMI project is common. The DBOT approach is common for utilities that want to essentially outsource the project to a general project contractor or an AMI company or their partner. The City should consider the effort required to manage AMI HES, MDMS and network to assess if a managed service option would be better compared to DBOT (or having the systems implemented at the City by internal resources or contractors). The overall cost in having a managed service compared to having the systems hosted by the City should also be evaluated. Black & Veatch recommends for the City to consider the hosted option for AMI, MDMS Network management and Customer Portal as the vendors can provide cost effective services and experienced resources that can ramp up the project quickly. The City will have to train or hire resources with the right skills to manage AMI system and the cost of these resources and maintenance of the IT Systems by the City might be more as compared to the vendor service offerings. Black & Veatch recommends the City to leverage the experience and knowledge of an industry consultant/implementation partner. This will allow the City to leverage subject matter experts in the design and implementation of the AMI project. 11.2 PROCUREMENT APPROACH One of the most important lessons learned in the industry from previous AMI initiatives is that it is crucial to select the right partners. There are several partners the City will need to choose as it BLACK & VEATCH I Project Roadmap 25G-171 53
