Item 2. Management's Discussion and Analysis of Financial Condition and Results
 of Operations
Dollar amounts in this discussion are rounded to the nearest
$1,000.IntroductionThe consolidated financial statements include the accounts of
the Trust and the limited partnerships owning the Providence Project and the
California Pumping project. The Trust uses the equity method of accounting for
its investments in the Maine Hydro Projects, the Maine Biomass Projects and the
Santee River Rubber Project, which are owned 50% or less by the Trust.
Results of Operations
In the second quarter of 2001, the Trust had total revenue of $1,981,000, which
is comparable with total revenue of $1,963,000 in the same period in 2000. Total
revenues for the first six months of 2001 of $3,797,000 were also comparable
with total revenue of $3,829,000 in the same period in 2000. Cost of sales of
$1,520,000 in the second quarter of 2001 ($2,991,000 in the first six months of
2001) were also comparable with the cost of sales of $1,511,000 in the same
period in 2000 ($3,092,000 in the first six months of 2000).

General and administrative expenses in the second quarter of 2000 of $346,000
were higher than the $281,000 recorded in the same period for 2001, primarily
due to legal fees in 2000 related to a potential investment that was abandoned
in prior years. General and administrative expenses for the first six months of
2000 of $491,000 were also higher than the $448,000 recorded in the same period
in 2001 for the same reason. Management fees increased to $171,000 in the second
quarter of 2001 ($420,000 in the first six months of 2001) as compared to the
$107,000 for the same period in 2000 ($213,000 in the first six months of 2000),
as a result of the Managing Shareholder's decision to resume taking 100% of the
management fee effective January 1, 2001. In 2000, the Managing Shareholder had
waived 50% of the management fee.

Interest expense was reduced from $95,000 in the second quarter of 2000
($194,000 for the first six months of 2000) to $77,000 in the second quarter of
2001 ($159,000 for the first six months of 2001) due to lower borrowings
outstanding at the Providence Project.

Equity income from the Maine Hydro Projects for the first six months of 2001
decreased to $271,000 from $662,000 for the same period of 2000. Income for the
second quarter of 2001 was $252,000, a decrease of $154,000 as compared to
second quarter 2000 income of $406,000. The decrease in income is due to the
below average river flows for 2001.

The equity loss from the Maine Biomass Projects increased from $88,000 in the
second quarter of 2000 ($170,000 for the first six months of 2000) to $191,000
in the second quarter of 2001 ($414,000 for the first six months of 2001) due to
the expenses of staffing and preparing the West Enfield plant for full time
operation.

The equity loss in the Santee River Rubber project of $181,000 for the first six
months of 2000 did not recur due to the writedown of the project in the third
quarter of 2000.

Liquidity and Capital Resources

In 1997, the Trust and Fleet Bank, N.A. (the "Bank") entered into a revolving
line of credit agreement, whereby the Bank provides a committed line of credit
facility of $1,150,000. The line of credit facility expires in July 2002.
Outstanding borrowings bear interest at the Bank's prime rate or, at the Trust's
choice, at LIBOR plus 2.5%. The credit agreement requires the Trust to maintain
a ratio of total debt to tangible net worth of no more than 1 to 1 and a minimum
debt service coverage ratio of 2 to 1. The credit facility was obtained in order
to allow the Trust to operate using a minimum amount of cash, maximize the
amount invested in Projects and maximize cash distributions to shareholders. In
the first quarter of 2000, the Trust borrowed $500,000 under the credit
facility.

Obligations of the Trust are generally limited to payment of the management fee
to the Managing Shareholder, scheduled long-term debt payments related to the
Providence Project and payment of certain accounting and legal services to third
parties. The Trust ceased making distributions to shareholders in the first
quarter of 2000.

The Trust anticipates that its cash flow during 2001 will be adequate to fund
its obligations.

Forward-looking statement advisory

This Quarterly Report on Form 10-Q, as with some other statements made by the
Trust from time to time, contains forward-looking statements. These statements
discuss business trends and other matters relating to the Trust's future results
and the business climate and are found, among other places, in the notes to
financial statements and at Part I, Item 2, Management's Discussion and
Analysis. In order to make these statements, the Trust has had to make
assumptions as to the future. It has also had to make estimates in some cases
about events that have already happened, and to rely on data that may be found
to be inaccurate at a later time. Because these forward-looking statements are
based on assumptions, estimates and changeable data, and because any attempt to
predict the future is subject to other errors, what happens to the Trust in the
future may be materially different from the Trust's statements here.

The Trust therefore warns readers of this document that they should not rely on
these forward-looking statements without considering all of the things that
could make them inaccurate. The Trust's other filings with the Securities and
Exchange Commission and its Confidential Memorandum discuss many (but not all)
of the risks and uncertainties that might affect these forward-looking
statements.

Some of these are changes in political and economic conditions, federal or state
regulatory structures, government taxation, spending and budgetary policies,
government mandates, demand for electricity and thermal energy, the ability of
customers to pay for energy received, supplies of fuel and prices of fuels,
operational status of plant, mechanical breakdowns, availability of labor and
the willingness of electric utilities to perform existing power purchase
agreements in good faith. Some of the cautionary factors that readers should
consider are described in the Trust's most recent Annual Report on Form 10-K.

By making these statements now, the Trust is not making any commitment to revise
these forward-looking statements to reflect events that happen after the date of
this document or to reflect unanticipated future events.
