"The US electric transmission and distribution network is a complex composition of lines that traverse around 365,000 circuit miles to supply electricity to the nation. The majority of the existing transmission infrastructure was put in place in the 1950's and 1960's and according to the US Department of Energy, around 70% of the power transformers are over 25 years old and around 60% of the circuit-breakers are 25 years old. This is causing bottlenecks for transmission operators to efficiently supply electricity to consumers.

Research and analysis highlights
Installed power generation capacity in the US grew at a CAGR of 1.9% from 783GW in 1990 to 1,104GW in 2008. The highest growth in additional capacity was recorded during 2000–2005 primarily due to an improved financial environment aiding the easy availability of credit, coupled with demand from an increase in industrial activities.
Generation from renewables in the US grew at a CAGR of 2% from 351,485GWh in 2004 to 381,044GWh in 2008, primarily driven by growth in Washington and California. The top 10 states in the US contribute 69.2% of the total renewable power generation in the country.
Implementing demand response that has an impact on reducing peak load requires support technology. Some of the key technologies enabling demand response include thermostats, interval meters, energy management systems, dynamic lighting controls and dynamic energy storage systems.

Integrating renewables- the race for smart grids
Just 10 states deliver over two-thirds of all renewable energy power generation in the United States, according to latest research form independent analyst, Business Insights.
Latest available figures show that electricity generation from renewables in the US grew at a compound annual growth rate (CAGR) of 2% from 351,485GWh in 2004 to 381,044GWh in 2008, primarily driven by growth in Washington and California
Paul Marshall, energy analyst at Business Insights, comments: “One of the largest challenges in integrating renewable power is that of intermittency associated with renewable energy sources such as wind and solar, which affects grid stability and security.
“Whilst renewable energy delivery is led by just a handful of states, states across the US are planning to increase the transmission and distribution infrastructure in order to accommodate an anticipated increase in renewable power capacity.”
The US renewable power generation capacity reached 139,485MW at the end of 2008, representing 12.6% of the total power generation capacity in the country. The renewable power generation capacity in the US grew at a CAGR of 4.3% from 117,760MW in 2004.
“Utilities and states across the US are investing in intelligent grid systems which can provide real-time intelligence and data to effectively integrate intermittent renewable power. According to a survey conducted by Capgemini and Platts, 48% of US utilities have adopted a smart grid strategy, while 52% have one under development,” concludes Paul.
