Nevada Energy - Demand Response Management System

Nevada Energy - Demand Response Management System

Country: U.S.A.
City: State of Nevada
Beneficiary: Nevada Energy, inhabitants of Nevada
Client: Nevada Energy
Status of the project: in operation


 

The context

Nevada Energy (NVE) is a large investor-owned utility based in Las Vegas, Nevada.  The company generates, transmits and distributes electric service covering 97% of Nevada, including the Las Vegas Valley.  It serves about 2.5 million residents and over 40 million tourists annually with operating revenue of $2.9 billion.  NVE has offered various Demand Response (DR) programs over the past decade and currently manages a portfolio of Residential, Commercial, and Industrial DR programs totaling 200+ MW of available DR capacity.

NVE launches new DR programs with the next generation of technology without abandoning the legacy DR infrastructure and technology used in the prior years.  Indeed, by 2010 NVE had four different type of Load Management Systems (LMS) in operation; one from CSE, one from Cooper/Cannon, one from Carrier, one from Comverge and was selecting a fifth, from Control4, to go into production in the coming year.

The solution

Therefore, in June of 2010, NVE selected DRBizNet (eterraDRBizNet 3.0 – “Retail DRMS”) as its DRMS to be the command and control system to manage NVE’s fleet of DR programs and technologies. The DRBizNet program enables to have a larger view and thus to have more flexibility to manage energy in optimal way (technical and financial aspects).

NVE views Demand Response as an integral part of their demand side management program efforts and uses DR for many purposes within NVE spanning across multiple internal organizations and drivers.   The key business uses of DR are as follows:

1. Operations:  Reduce targeted load during peak periods at substations that are overloaded to avoid blackouts.
2. Trading Desk:  Reduce overall load 15 to 30 minutes as non-spin generation comes on line.
3. Trading Desk:  Reduce overall peak load to minimize purchasing real time energy at high prices.
4. Engineering Planning:  Defer substation upgrade capital expenditures by targeting where they need DR implemented.

 

The benefits

The Nevada Energy project aims to face to peak loads by promoting Demand-Response. It is an effective way both to low the CO2 emissions and provide power quality while keeping the grid resilient and secure.

The platform eterraDRBizNet 3.0 provides a comprehensive end-to-end DRMS to be the command and control system that manages all activities and data related to Demand Response for NVE.  The DRMS is the:

• Single point of DR Program Management and Operations.
• Single point of registration for all DR programs including Residential, Commercial & Industrial programs.
• Single view of availability of DR resources across the network model down to the feeder view.
• Single Command and Control event management system.
• Single point of integration to back office systems as well as to legacy and new DR devices.
• Calculation engine to measure customer performance to calculate settlements.
• Single system of record for all data and transactions related to DR programs and events.

NVE’s estimated annual environmental benefit from its Demand Response programs for 2013 :

- Energy Savings (kWH): 11,170,000.
- Peak Year KW impacts: 223,000.
- Sulfur Dioxide (lbs): 14,409.
- Carbon Dioxide (lbs): 13,322,474.

Special features of the French offer

In Nevada project, the consumer is in the heart of the project. He can take part effectively to the DR and thus contribute to energy load reduction during times of peak demand. NVE’s DRMS now manages:

• 14 active DR Programs, 11 Residential, 2 Commercial and 1 Industrial program.
• 80,000 residential, and C&I devices.
• 200+ MW of available DR.
• Across 200+ substations & 1300 feeders.
• Managing 5+ device technology types.

Alstom provided the Project Management to manage the DRMS requirements gathering, software configuration, implementation, support of integration to back office systems, and DRMS testing.  Alstom also provided the Business Analysts to review the NVE programs, processes, data flows, integrations, user roles, and key functionality requirements.  Alstom also configured the DRMS and provided custom software development and support as needed.  Many innovations developed by Alstom R&D have been introduced as part of this project:

- Several modules that manage the entire lifecycle and operations of Demand Response programs work seamlessly together. Extensions available have been implemented to support Renewable Distributed Energy Resources such as batteries, solar inverters, and wind resources.

- The Retail DRMS can be configured to use all or only a subset of modules to meet the requirements of a more limited scope customer.  This modularity allows the Retail DRMS platform to scale down to a simple DRMS for pilots or small DR programs and without upgrading, just simple configuration, the system can be extended to turn on the additional modules as needed, when needed.  So Alstom’s Retail DRMS can be used to manage 1MW of DR up to 1GW of DR or more.
