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.

Introduction

The 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

     Quarter ended March 31, 2000 compared to quarter ended March 31, 1999

In the first quarter of 2000, the Trust had total revenue of  $1,866,000,  which
is a 4% increase from the total revenue of $1,794,000 in the same period in 1999
due to  increased  production  at the  Providence  plant.  Cost  of  sales  also
increased from $1,522,000 in the first quarter of 1999 to $1,581,000 in the same
period in 2000 as a result of higher engine  maintenance costs at the Providence
Project.

General and  administrative  expenses  in the first  quarter of 2000 of $145,000
were $38,000 lower than the $183,000  incurred with the same period in 1999, due
to lower  accounting  and  professional  fees. The management fee decreased from
$117,000 in the first  quarter of 1999 to $106,000 in the same period in 2000 as
a result of lower Trust net asset balances used to determine such fees.

Interest income declined by $15,000 from $24,000 in the first quarter of 1999 to
$9,000 in the first quarter of 2000 due to lower average cash balances. Interest
expense was  reduced by $16,000  from  $115,000 in the first  quarter of 1999 to
$99,000 in the first quarter of 2000 due to lower borrowings  outstanding at the
Providence project.

Equity income from the Maine Hydro Projects  decreased $281,000 from $537,000 in
the first  quarter of 1999 to $256,000 in the same period in 2000,  due to lower
production because the above-average  river flows in 1999 did not recur in 2000.
The  equity  loss from the  shut-down  Maine  Biomass  Projects  decreased  from
$168,000 in the first  quarter of 1999 to $70,000 in the same period in 2000 due
to cost  reductions  and sales of installed  capacity at the plants.  The equity
loss in the Santee  River  Rubber  project  increased  from  $7,000 in the first
quarter  of 1999 to  $82,000  in the  first  quarter  of 2000 due to the cost of
staffing  the  project for the current  testing  and  modification  stage of the
project.

     Quarter ended March 31, 1999 compared to quarter ended March 31, 1998.

In the first quarter of 1999, the Trust had total revenue of  $1,793,000,  which
is comparable  with total revenue of $1,795,000 in the same period in 1998. Cost
of sales increased to $1,522,000 in the first quarter of 1999 from $1,124,000 in
the same period in 1998 as a result of higher  engine  maintenance  costs at the
Providence Project.

General and  administrative  expenses  in the first  quarter of 1999 of $183,000
were  comparable with the same period in 1998. The management fee decreased from
$280,000  in the first  quarter of 1998 to  $117,000  in the same period in 1999
primarily  as a result of the  Managing  Shareholder's  decision to  voluntarily
waive one-half of its management fee for an indefinite period.

Interest  income declined by $140,000 from $164,000 in the first quarter of 1998
to $24,000  in the first  quarter of 1998 due to lower  average  cash  balances.
Interest  expense was reduced by $14,000 from  $129,000 in the first  quarter of
1998  to  $115,000  in  the  first  quarter  of  1999  due to  lower  borrowings
outstanding at the Providence project.

Equity income from the Maine Hydro Projects  increased $210,000 from $327,000 in
the first  quarter of 1998 to  $537,000 in the same period in 1999 due to higher
production  because of  above-average  river  flows.  The  equity  loss from the
shut-down Maine Biomass Projects decreased from $268,000 in the first quarter of
1998 to $168,000 in the same period in 1999 due to cost  reductions and sales of
installed capacity at the plants.

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 three year committed line
of credit  facility of $1,150,000.  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.

As disclosed in the Trust's  Annual  Report on Form 10-K for the year 1999,  the
Santee  River  Project  has   experienced   material   design  and   performance
inadequacies that will require additional sequential  alterations and additional
work to be paid for by the  Contractor.  The  Contractor  is  continuing to make
repairs and  modifications at its own cost, but the Project requires  additional
capital in order for it to remain open and available to the  Contractor for this
work. The Trust and Environmental  Processing Services, Inc., the developer, are
discussing  potential  financing  alternatives but no agreement has been reached
and there is no  assurance  that  agreement  will be reached  before the Project
exhausts its working capital.

The Contractor is currently  defraying debt service on the construction debt for
the Project and is  obligated  to do so until  August 9, 2000,  when  letters of
credit securing the debt will become available

The Managing Shareholder announced a cessation of distributions in April 2000.

Obligations of the Trust are generally  limited to payment of Project  operating
expenses, payment of a management fee to the Managing Shareholder,  payments for
certain accounting and legal services to third persons,  repayment of borrowings
under  the  line of  credit  and  distributions  to  shareholders  of  available
operating cash flow generated by the Trust's investments.  The Trust's policy is
to distribute as much cash as is prudent to shareholders. Accordingly, the Trust
has not found it necessary to retain a material amount of working  capital.  The
amount of working capital retained is further reduced by the availability of the
line of credit facility.

The Trust  anticipates that, during 2000, its cash flow from operations and line
of credit facility 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,  has  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.
