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

In the second quarter of 2000, the Trust had total revenue of $1,963,000,  which
is comparable with total revenue of $1,878,000 in the same period in 1999. Total
revenues  for the first six months of 2000 of  $3,829,000  were also  comparable
with total revenue of  $3,671,000  in the same period in 1999.  Cost of sales of
$1,511,000 in the second quarter of 2000  ($3,092,000 in the first six months of
2000)  were also  comparable  with the cost of sales of  $1,564,000  in the same
period in 1999 ($3,086,000 in the first six months of 1999).

General and  administrative  expenses in the second  quarter of 2000 of $346,000
were higher than the $169,000 recorded in the same period in 1999, primarily due
to higher legal fees  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 $352,000  recorded in the same period
in 1999 for the same reason.  Management  fees of $107,000 in the second quarter
of 2000  ($213,000  in the first  six  months of 2000)  were  comparable  to the
$117,000 in the same period in 1999 ($234,000 in the first six months of 1999).

Interest  expense  was  reduced  from  $111,000  in the  second  quarter of 1999
($226,000 for the first six months of 1999) to $95,000 in the second  quarter of
2000  ($194,000  for the  first  six  months  of 2000)  due to lower  borrowings
outstanding at the Providence Project.

Although equity income from the Maine Hydro Projects for the first six months of
2000 of $662,000 was  comparable to $655,000 in the same period of 1999,  income
in the second  quarter of 2000 of  $406,000  was  substantially  higher than the
second  quarter  1999  income of  $118,000.  The river  flows were higher in the
second quarter of 2000 compared to the prior year but lower in the first quarter
of 2000 compared to the prior year.

The  equity  loss from the  shut-down  Maine  Biomass  Projects  decreased  from
$242,000  in the second  quarter of 1999  ($410,000  for the first six months of
1999) to  $88,000  in the second  quarter  of 2000  ($170,000  for the first six
months of 2000) due to higher energy revenues and reduced maintenance costs.

The Trust recorded losses from its equity interest in the Santee River Rubber in
2000  ($181,000  for the first six months and  $111,000  in the second  quarter)
compared to income in 1999  ($64,000 for the first six months and $71,000 in the
second  quarter)  because the project was under  construction  in 1999,  but was
fully staffed and undergoing testing in 2000.

The increase in the minority interest in the earnings of the Providence  Project
from $18,000 in the second  quarter of 1999 ($83,000 for the first six months of
1999) to  $51,000  in the second  quarter  of 2000  ($109,000  for the first six
months of 2000) is a result  of  higher  earnings  from the  Providence  Project
caused primarily by lower maintenance costs.

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  did not operate at full  capacity  because of design and
equipment performance problems.  The Project's general contractor,  as required,
began repairs and modifications at its own cost in January 2000, but the Project
has required  additional  capital in order to pay for normal operating costs and
to allow the contractor to finish pre-operating testing.

In late  May  2000,  Environmental  Processing  Services,  Inc.,  the  Project's
developer,  informed the Trust that the Project  needed  substantial  additional
money to pay for its  operating  expenses  while the repairs were  completed and
during the testing.  Intensive  negotiations  then began  between  Environmental
Processing,  Ridgewood  Power, the Project's  bondholders and potential  outside
funding sources.  While these negotiations  continued,  the Project informed the
Trust on July 30,  2000 that it had run out of money and would be unable to make
payroll. After further discussions,  the bondholders agreed to allow $275,000 to
be drawn from the debt service reserves for operating expenses and the Trust and
Ridgewood  Electric Power Trust V advanced  $92,000 and $183,000,  respectively,
for that purpose.  The Project is operating on an irregular  schedule because of
raw  material  and  operating   cost  delays,   but  it  is  possible  that  the
pre-operating  test will be completed  during the week of August 14,  2000.  The
Project  may  or  may  not  then  shut  down  for  an  indefinite  period  while
negotiations for further financing  continue.  Although Ridgewood Power has been
informally  advised  that the Project has obtained an extension of a payment due
date on its bonds, the Project may enter  bankruptcy or insolvency  proceedings.
Ridgewood Power,  the Project's  bondholders,  outside  financing and management
sources and principals of Environmental Processing continue to discuss potential
financing  alternatives.  Any new financing from sources other than the Trust or
the results of a bankruptcy reorganization might dilute, subordinate or possibly
eliminate the Trust's equity interest.  As of the date of this Quarterly Report,
the Trust  believes  that the  Project  can be  refinanced  on a basis that will
eventually allow the Trust to make a profit on the investment.

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 the
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, 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.

                           PART II - OTHER INFORMATION

Item 1. Legal Proceedings

On June 2,  2000,  Indeck  Maine  Energy  LLC,  the owner of the  Maine  Biomass
Projects,  brought a complaint before the Federal Energy  Regulatory  Commission
(Docket No. EL00-80-000)  requesting FERC to remove bid restrictions  imposed on
Indeck by ISO-New  England,  Inc.,  the operator of the New England  Power Pool.
Those restrictions capped the price that the ISO would pay for Indeck's electric
power output at approximately  $810 per  megawatt-hour,  substantially less than
Indeck's own bids. The complaint also  challenged the ISO's  authority to impose
those  restrictions.  On July 26,  2000 FERC  ordered the ISO "to remove the bid
restrictions  previously  imposed  on  Indeck."  FERC found that the ISO had not
provided  any  evidence to support  its  conclusion  that the Indeck  power bids
materially  affected the markets.  That conclusion was a necessary condition for
imposing the restrictions.

Because of their cost structure,  the Maine Biomass Projects  currently run only
during  power  shortages  in the summer  and  occasionally  at other  times when
transmission  constraints or local problems  require their use. Thus the lifting
of the bid  restrictions  will not  result in revenue  increases  unless a power
shortage or similar  situation  occurs in the future.  The Trust does not expect
any such situation to occur during the rest of the summer,  although the weather
in particular is unpredictable.

The FERC order does not expressly lift the bid restrictions for earlier dates in
2000 and certain  dates in 1999 on which the Projects  sold power to the ISO and
there is some  language in the order that could be read to say that FERC did not
invalidate the prior bid restrictions. The Trust believes that the order clearly
rejected  the reasons  given by the ISO for capping  Indeck's  prices on most of
those dates and also discredited the ISO's decision to impose caps retroactively
for the 1999 dates. The Trust intends to bring additional  complaints at FERC to
clarify the order,  to rescind the price caps for those prior dates on which the
Projects sold power and to recover additional compensation for those sales based
on the prices that Indeck had  submitted.  Until such  proceedings  are resolved
favorably to Indeck or unless a settlement with the ISO results,  the Trust will
receive no additional revenue from the ISO for those prior dates.

In addition,  the ISO has escrowed  approximately $287,000 of Indeck's revenues,
based on the ISO's  assertion  that an  overpayment  was made for a price-capped
event in October 1999.  The Trust  expects to bring an additional  proceeding in
the appropriate forum to recover the escrowed amount and to invalidate the caps.
