Duke & Cisco Team for Smart-Grids

Diversified utility Duke Energy (DUK - Snapshot Report), the 3rd largest electric utility in the U.S., announced a three-year partnership with Cisco Systems (CSCO - Analyst Report), the world's largest network communications company, to co-develop an advanced modern electric "smart grid."

What is a Smart-Grid?

"Smart-grids" deliver electricity from suppliers to consumers using digital technology to save energy, reduce costs and increase reliability. Many global governments are promoting such a modernized electricity network as a means of increasing energy independence and reducing global warming issues.

An electricity grid is not a single entity but an aggregate of multiple networks and multiple power generation companies with multiple operators employing varying levels of communication and coordination, most of which are manually controlled.

Smart grids increase the connectivity, automation and coordination between suppliers, consumers and networks, which perform either long distance transmission or local distribution tasks. Transmission networks move electricity in bulk over medium-to-long distances, are actively managed, and generally operate from 400kV to 800kV over AC and DC lines.

Local networks traditionally moved power in one direction, "distributing" the bulk power to consumers and businesses via lines operating at 132kV and lower. This paradigm is changing as businesses and homes begin generating more wind and solar electricity, enabling them to sell surplus energy back to their utilities.

Efficiency Through Technology

Modernization is necessary for energy consumption efficiency; real-time management of power flows; and to provide the bi-directional metering needed to compensate local producers of power. Although transmission networks are already controlled in real-time, many in the US and European countries are antiquated by world standards, and unable to handle modern challenges such as those posed by the intermittent nature of alternative electricity generation, or continental scale bulk energy transmission.

According to Deloitte, in 2009, smart grid providers may represent one of the largest and fastest growing sectors within the "clean," green energy industry. Deloitte forecasts that electricity, as a percentage of total energy consumption, will increase from 9% in 1973 to 16% through 2009.

Additionally, they estimate that modern smart-grids offer approximately twice the efficiency, at 60%, as the average efficiency of the world's legacy electricity grids at  approximately 33%.

Finally, Deloitte estimates that the annual cost  of power outages and power quality disturbances in the U.S. approximates $180 billion.

Likewise, a recent study by the U.S. Department of Energy study estimates that smart-grid modernization of U.S. electricity grids with would save between $46 to $117 billion over the next 20 years.

Among other conclusions, Deloitte deduces through its smart-grid analysis that "[M]ajor manufacturers and utilities should explore partnerships with, and consider acquisitions of, smart energy companies."  Such is the case we now see with Duke Energy and Cisco.

Both Companies Known as Trail-Blazers

At the risk of over-stating the significance of this relationship, particularly for the traditionally staid, 100+ year old electricity industry, both Duke Energy and Cisco rank as consensus innovative leaders in their respective industries. Under terms of the agreement, Cisco seeks to develop and deliver to Duke Energy a state-of-the-art, industry-leading, end-to-end, power plant-to-customer, smart-grid network communications infrastructure.

Empirically speaking, U.S. support for smart-grid technology became federal policy with passage of the Energy Independence and Security Act of 2007. Subsequently, smart-grids received additional support with the passage of the American Recovery and Reinvestment Act of 2009, which appropriated $11 billion for the creation of a smart-grid.

Support from the Federal Government

As recently as January 2009, in his National Address, President Obama requested Congress to pass legislation including the development of new electricity "smart-grids."  On March 19, 2009, The Federal Energy Regulatory Commission (FERC) issued a proposed policy statement and action plan for standards governing the development of a smart-grid. Successful progress toward national implementation of smart-grids continues.

Upon completion, the new, "internet protocol-based open standards" architecture will replace Duke's existing, antiquated analog electric grid with a long-overdue, secure digital backbone infrastructure.

The resultant smart-grid, widely thought to be replicated by other leading energy utilities, will modernize some the most outdated infrastructure in the U.S. – electricity delivery systems – with secure, reliable and efficient data, networks and communications.

The collaboration project will ultimately update the delivery to, and use of electricity by, Duke's 11 million customers served in five states: Ohio, Indiana, North Carolina, South Carolina and Kentucky. Throughout the term of the project, and in subsequent years, Duke will install large-scale new smart-grid technology, including millions of electric and natural gas "smart meters," in addition to hardware and software for distribution.

"Smart meters" replace analog mechanical meters with digital meters which record energy usage in real-time. Smart meters provide a communications pathway extending from generation plants to electrical outlets and other smart grid-enabled devices.

Manifold benefits await Duke Energy and its customers.

The proposed modernized electric grid will:

• Build an 'Energy Internet', which will enable decentralized power generation, so that customers may be both energy clients and suppliers; allow supplier selection of power consumption to offer flexibility to energy consumers;
• Integrate solar and other renewable energy sources into the electric grid;
• Encourage consumers to actively participate in operations of the grid; improve electricity delivery, improve systems efficiency and reliability, increase energy independence, decrease environmental impact, and help customers reduce their energy consumption, strengthen grid security and resist attack;
• Provide higher quality power that will save money wasted from outages;
• Incorporate two-way digital communication to detect power outages and be readily inter-operable, upgradeable and scalable to new emerging technologies.

Cisco has already begun sharing its networking expertise with leading utility providers around the world and is building innovative network solutions for them and their customers to monitor electricity utilization, optimize energy delivery, reduce energy usage and cost, improve system security, and lessen their impact on the environment.

Going forward, Cisco plans to continue to deliver products and services to support this initiative serving a growing smart grid communications infrastructure market projected by Cisco to reach $20 billion annually over the next five years.
