History is a great teacher. The Internet took decades to evolve and take shape.
Now upon us is a more critical challenge: how to build and sustain a smarter
power grid. The tech community is already starting to initiate significant
efforts to address this challenge, but here are some thoughts for how we can
learn from the history of how the Internet was built, which will help us move
into the fast-lane to tackle this massive task and monumental opportunity.

1. Scalable, Service-Driven Smart Grid Architecture: The smart grid needs to
develop architecture that can scale up quickly, driven by the same kind of
on-demand service-based models by which bandwidth is sold on the Internet. Like
the Internet, the smart grid represents a combination of systems at an
unprecedented scale: supporting millions of users demanding access to services
that must be responsive, robust and always available. The number of grid
communication sessions and grid access requests by interacting components
(producers, consumers and gateways) translates into a very high number of
network requests, placing an enormous demand on resources.

It is well-documented that power systems experience huge variations in service
load, with bursts coinciding with the times that the service has the most
value. In the early days of the Internet, the network relied upon the scaling
capabilities of the operating system UNIX. Later, several systems capable of
handling high-volume transactions were developed and coined as ?Internet
Servers.? Similar capabilities need to be provisioned for servers of the
smart grid.

2. Defined Communication Protocols: The smart grid needs to standardize around a
set of protocols and, importantly, define a key protocol for smart-grid
communications. It could even take a cue from, and if necessary re-architect,
the Open Systems Interconnection Reference Model to adapt to the ?Internet of
Things.? In the case of the Internet, the Internet Protocol Suite (also
referred to as TCP/IP) enabled a common inter-network protocol and, instead of
the network being responsible for reliability (as in the ARPANET), the hosts
became responsible. With the role of the network reduced to a bare minimum, it
became possible to connect almost any network, with any characteristics,
together. A similar protocol design will be essential for the smart grid, given
the immediate need to connect diverse component types.

3. Security & Encryption: The smart grid community needs to publish detailed
specifications for different levels of security and encryption standards. For
secure communication purposes, the Internet leveraged data encryption
standards, including variants of Digital Encryption Standard (DES) as endorsed
by the National Institute of Science & Technology (NIST). To ensure secure user
authentication and data integrity, techniques like digital signatures and the
network authentication protocol Kerberos were also created. Some of these
standards are openly available whereas certain encryption tools are patented
and require licensing.

Similarly, smart grid security needs to be thoroughly investigated to enable a
multi-tiered security model for the grid. Once this is done, startups should be
encouraged to build innovative tools that adhere to these standards. It?s
important to note that the smart grid?s cyber-security layer may need to be
more regulated (by federal policies) than the Internet?s has been, given the
potential direct impact on national security systems. (See more details in No.
9.)

4. Management & Communication Tools for Energy: Simple HTML pages publicized the
concept of the Internet to the common user back in the mid-1990s. A tool like
this that offers a rich user experience can help in connecting the customer to
the concept of the smart grid.

5. Open APIs: Companies building the next generation of the smart grid need to
regularly publish APIs through working-groups and to meet specification
requests. As they have done for the Internet, open APIs would ensure ease of
integration of the grid with different endpoints, like smart meters, advanced
metering infrastructure (AMI), programmable logic controllers (PLC), wireless
mesh networks and portal gateways.

6. Find the Killer App: The smart grid needs to clearly evangelize its first
killer app that could appeal across all grid user communities, including
customers, utilities, the federal government, local governments and business
sectors. Email did the trick for the Internet. So what will it be for the smart
grid? Demand response? Energy management?

7. Connect the Grid to Consumers: Extend the functionality of the smart grid
into a variety of always-on lifestyle interfaces, including meters, panels,
garages, vehicles, recharging stations and mobile devices. The Internet really
took off within universities (and then everywhere else) because of the concept
of the ?browser.? From that point on, Internet access wasn?t tied to an
IBM supercomputer or a Windows proprietary desktop. With that shift, the
tantalizing possibilities of open access invited strong investment, and we
continue to reap more benefits of such a model more than two decades later.

8. Make a Task Force: The smart grid?s standardized framework needs to be
driven by an engineering task force, similar to the Internet Engineering Task
Force. Like the IETF, the smart grid task force (SGTF) would produce high
quality, relevant technical and engineering documents that influence the way
people design, use and manage the smart grid in such a way as to make the smart
grid work better. These documents would include protocol standards, best current
practices, and other informational documents. When the informational tools are
dispersed, let application innovation (driven by businesses) drive the growth.

9. Allow for Secure Grid Layer: OK, this one is a little specific, but still
quite relevant given the Internet?s roots with the Department of Defense.
Because power grid security is so important, the smart grid needs to build
policies and procedures that allocate a limited percent of a grid layer to be
fully regulated and completely off limits for business access. This layer can
be used for Pentagon/DoD grade security for administering, monitoring and
controlling the resources and functions of the grid. It would basically be a
virtual nerve center with selective access. While the Internet doesn?t have a
nerve center per se, certain secure transmissions leverage the same distributed
collaboration-architectures, and are fully controlled for classified access
only ? e.g., command and control communications.

10. Recovery in a Disaster: In the event of an emergency or disaster, the smart
grid needs to have a fault-tolerant channel and ensure that all resources are
set up for collaboration to deliver an automated, self-healing recovery
operations process. This channel should not disrupt any other basic channels of
communications or utility services. In the early days of the Internet, the
network was successfully able to keep basic telephony services running during
network disasters.

11. Government Labs: Over the years, as the smart grid matures in the open
market, it is important for a smart grid governing body to still own and
maintain state-of-the art lab environments to focus on the technologies
involved. This ensures that the smart grid will still be current, open and
standardized and not influenced too greatly by specific vendor interests. In
the case of the Internet, the Department of Defense created ARPANET, which was
helpful in the development of early application-services like email, FTP and
protocols like NCP and TCP/IP.

12. Demonstrate the Value: Finally, but probably most importantly, the smart
grid needs to develop and clearly communicate and market its value proposition.
Basically: Why do we need the smart grid now? This should be demonstrated and
measured in terms of economics, lifestyle enhancements, energy conservation,
and renewable energy integration. The value proposition of the Internet ?
making the world smaller and connecting every one of us ? was more clear to
consumers, and the Internet was its own chief marketing officer in its early
days.
