Safe Harbor Provisions

This presentation contains statements concerning NU’s expectations, beliefs, plans, objectives, goals, strategies, assumptions of future events, future financial performance or growth and other statements that are not historical facts. These statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, a listener or reader can identify these forward-looking statements through the use of words or phrases such as “estimate”, “expect”, “anticipate”, “intend”, “plan”, “project”, “believe”, “forecast”, “should”, “could”, and other similar expressions. Forward-looking statements are based on the current expectations, estimates, assumptions or projections of management and are not guarantees of future performance. These expectations, estimates, assumptions or projections may vary materially from actual results. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that could cause our actual results to differ materially from those contained in our forward-looking statements, including, but not limited to,actions or inaction of local, state and federal regulatory and taxing bodies; changes in business and economic conditions, including their impact on interest rates, bad debt expense and demand for our products and services; changes in weather patterns; changes in laws, regulations or regulatory policy; changes in levels and timing of capital expenditures; disruptions in the capital markets or other events that make our access to necessary capital more difficult or costly; developments in legal or public policy doctrines; technological developments; changes in accounting standards and financial reporting regulations; fluctuations in the value of our remaining competitive electricity positions; actions of rating agencies; and other presently unknown or unforeseen factors. Other risk factors are detailed from time to time in our reports to the Securities and Exchange Commission (SEC). Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to update the information contained in any forward-looking statements to reflect developments or circumstances occurring after the statement is made or to reflect the occurrence of unanticipated events.

This presentation references actual and projected EPS by business, a non-GAAP presentation, which management believes is useful to investors to evaluate the actual and projected financial performance and contribution of our businesses. This non-GAAP financial measure should not be considered as alternatives to our consolidated net income attributable to controlling interests, and EPS determined in accordance with GAAP as an indicator of operating performance.

Please refer to our reports to the SEC for further details concerning the matters described in this presentation.

New England Continues to be a First Mover in Resolving Transmission Reliability and Promoting Clean Energy Solutions

  • The ability to plan and deploy significant Transmission infrastructure has been proven

    • Each year (since 2000) ISO-NE provides a robust 10-year Regional System Plan

    • Over $4B of reliability work has been successfully completed through this process

    • Another $6B of transmission projects are part of the current Regional System Plan

    • Connecticut customers alone have already benefited by more than $500M since 2007

  • The commitment to clean energy is demonstrable at both state and regional levels

    • New England is a leader in the U.S. in promoting energy conservation and demand-side management

    • Each state has RPS targets and participates in the Regional Greenhouse Gas Initiative

    • Connecticut and Massachusetts are taking a pragmatic approach to smart grid deployment

  • The region’s clean energy objectives and resources are significant

    • The region is long on renewables through 2013; a shortfall widens by 2020

    • Substantial renewable potential exists in Northern New England, Canada and off-shore

    • This potential is large-scale but, in almost all instances, distant from regional load centers

  • Regional transmission solutions can integrate distant renewable resources with innovative power technologies to achieve clean energy objectives

New England’s Clean Energy Challenges

The Southwest Connecticut Projects Demonstrated Our Ability to Site, Permit, Construct and Operate Transmission Projects in Numerous Challenging Environments

Four southwest CT transmission projects completed at a cost of $1.6 billion; nearly $80 million under budget and one year ahead of schedule

Congestion cost savings to Connecticut customers, since 2007, in excess of $500M

  • Current Status

  • Following favorable FERC decision in May 2009, NU and NSTAR have been working to advance key agreements

    • JDA with HQ-TransEnergie

    • TSA with HQ-US for filing with FERC

    • PPA for review by states

  • Significant “project” work under way

    • Routing and early engineering

    • Determination of southern terminus and associated AC upgrades

    • Discussions with federal agencies regarding Presidential Permit and Special Use Permit from USFS

Renewable Energy Projections

Estimated Class I Renewable Energy Requirements for New England in 2020 is 22,800 GWh’s

6,600 GWh = Existing Available Renewables

3,500 GWh = Currently Planned or Under Development

12,700 GWh = Unplanned Renewables/Balance Shortfall

Class I Technologies include:

> Biomass/Biofuels > Fuel Cells (CT)

> Landfill Gas > Small Hydro

> Solar PV > On and Offshore Wind

Renewable Capacity Needed to Fill 2020 Shortfall

Wind (on-shore & off-shore)

Other Class I Technologies

~ 3,300 MW

~ 500 MW

This implies a significant amount of new projects, each requiring connection and integration with New England’s power delivery infrastructure

  • Our pursuit of New England’s clean energy objectives is a platform for continued investment, collaboration and technology innovation

What is congestion
What is Congestion? Initiatives Since 2006

  • Energy requirements in a region are met by a combination of the most economic generating resources being dispatched and energy imports into the region over transmission lines.

  • When the energy requirements in a region exceed the maximum level of energy imports over transmission lines, less economic generation in that region is dispatched.

  • Congestion is a measure of the expense of the uneconomic generation being dispatched compared against what could have been imported if more transmission import capability was available.

  • By increasing transmission import capability, congestion expense can be reduced along with the emissions associated with the uneconomic generation being dispatched.
