3.  Summary of Significant Accounting Policies

New Accounting Standards and Disclosures

SFAS 143
In June  2001,  the FASB  issued  SFAS  143,  Accounting  for  Asset  Retirement
Obligations, on the accounting for obligations associated with the retirement of
long-lived  assets.  SFAS 143  requires  a  liability  to be  recognized  in the
consolidated  financial  statements for retirement  obligations meeting specific
criteria.  Measurement of the initial  obligation is to approximate  fair value,
with  an  equivalent  amount  recorded  as an  increase  in  the  value  of  the
capitalized  asset.  The asset will be  depreciated  in  accordance  with normal
depreciation  policy and the  liability  will be increased for the time value of
money, with a charge to the income  statement,  until the obligation is settled.
SFAS 143 is effective for fiscal years  beginning after June 15, 2002. The Trust
adopted  SFAS 143  effective  January 1, 2003,  with no  material  impact on the
consolidated financial statements.

SFAS 145
In April 2002, the FASB issued SFAS No. 145,  Rescission of FASB  Statements No.
4, 44, and 64,  Amendment of FASB  Statement No. 13, and  Technical  Correction.
SFAS No. 145 eliminates extraordinary accounting treatment for reporting gain or
loss  on  debt   extinguishment,   and  amends  other   existing   authoritative
pronouncements  to make various  technical  corrections,  clarify  meanings,  or
describe their applicability  under changed  conditions.  The Trust adopted SFAS
145  effective  January 1, 2003,  with no  material  impact on the  consolidated
financial statements.

SFAS 146
In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with
Exit or Disposal  Activities.  SFAS No. 146 requires  recording costs associated
with exit or disposal  activities at their fair values when a liability has been
incurred. The Trust adopted SFAS 146 effective January 1, 2003, with no material
impact on the consolidated financial statements.

FIN 45
In  November  2002,  the FASB  issued  FASB  Interpretation  No. 45 ("FIN  45"),
"Guarantor's  Accounting and Disclosure  Requirements for Guarantees,  Including
Indirect  Guarantees  and  Indebtedness  of Others."  FIN 45  elaborates  on the
disclosures  to be made by the  guarantor  in its interim  and annual  financial
statements about its obligations under certain guarantees that it has issued. It
also requires  that a guarantor  recognize,  at the inception of a guarantee,  a
liability  for the fair  value  of the  obligation  undertaken  in  issuing  the
guarantee.   The  initial   recognition  and  measurement   provisions  of  this
interpretation  are  applicable on a prospective  basis to guarantees  issued or
modified  after  December  31,  2002;  while the  provisions  of the  disclosure
requirements are effective for financial statements of interim or annual reports
ending after December 15, 2002.  The Trust adopted the disclosure  provisions of
FIN 45  during  the  fourth  quarter  of 2002  with no  material  impact  to the
consolidated financial statements.

FIN 46
In January 2003, the FASB issued FASB  Interpretation No. 46,  "Consolidation of
Variable  Interest  Entities" ("FIN 46") which changes the criteria by which one
company includes another entity in its consolidated financial statements. FIN 46
requires  a variable  interest  entity to be  consolidated  by a company if that
company is subject to a majority of the risk of loss from the variable  interest
entity's  activities or entitled to receive a majority of the entity's  residual
returns or both. The  consolidation  requirements of FIN 46 apply immediately to
variable  interest  entities  created after  January 31, 2003,  and apply in the
first  fiscal  period  beginning  after June 15,  2003,  for  variable  interest
entities  created prior to February 1, 2003.  The Trust  adopted the  disclosure
provisions of FIN 46 effective December 31, 2002, with no material impact to the
consolidated financial statements.  The Trust implemented the full provisions of
FIN 46 effective July 1, 2003.

SFAS 150
In May 2003,  the FASB  issued SFAS No. 150,  Accounting  for Certain  Financial
Instruments with  Characteristics  of both Liabilities and Equity.  SFAS No. 150
establishes   standards  for   classifying  and  measuring   certain   financial
instruments  with  characteristics  of both  liabilities  and equity.  The Trust
adopted  SFAS  150  effective  July 1,  2003,  with no  material  impact  on the
consolidated financial statements.

4. Qualification of the Providence Project

On  January  17,  2003,  the  Providence   Project   received  a  "Statement  of
Qualification"  from the  Massachusetts  Division of Energy  Resources  ("DOER")
pursuant to the renewable  portfolio standards ("RPS") adopted by Massachusetts.
In 1997,  Massachusetts  enacted  the  Electric  Restructuring  Act of 1997 (the
"Restructuring  Act").  Among other things,  the Restructuring Act requires that
all retail electricity suppliers in Massachusetts (i.e. those entities supplying
electric energy to retail end-use customers in Massachusetts) purchase a minimum
percentage of their electricity supplies from qualified new renewable generation
units  powered  by one of several  renewable  fuels,  such as solar,  biomass or
landfill.  Beginning in 2003, each such retail supplier must obtain at least one
(1%) percent of its supply from qualified new renewable  generation  units. Each
year  thereafter,  the requirement  increases  one-half of one percentage  point
until  2009,  when the  requirement  equals  four (4%)  percent  of each  retail
supplier's  sales  in  that  year.  Subsequent  to  2009,  the  increase  in the
percentage requirement will be determined and set by the DOER.

Now that the Providence Project has been qualified as new renewable  generation,
it receives RPS Attributes that it may sell to retail electric suppliers. Retail
electric suppliers may purchase RPS Attributes  associated with renewable energy
and  not  necessarily  the  energy  itself.  Thus,  electrical  energy  and  RPS
Attributes are separable products and need not be sold or purchased as a bundled
product.  Retail electric  suppliers in Massachusetts will then use the purchase
of such RPS Attributes to demonstrate  compliance with the Restructuring Act and
RPS Regulations.

In the first quarter of 2003, the Providence  Project  entered into a three year
agreement  to sell all its RPS  Attributes  to a retail  electric  supplier.  On
February 13, 2003, the  Providence  Project sold and recorded  revenue  totaling
$336,750  for the RPS  Attributes  derived  from the  power  produced  in fourth
quarter of 2002.

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 and the Maine Biomass Projects,  which are owned 50% by
the Trust.

Critical Accounting Policies and Estimates

For a complete discussion of critical accounting policies, refer to "Significant
Accounting Policies" in Item 7 of the Trust's 2002 Form 10-K. There have been no
substantive changes to those policies and estimates. Results of Operations

Three Months Ended June 30,2003, Compared to the Three Months Ended June 30,2002

Total  revenue  for the  second  quarter  of 2003 was  $2,058,000,  compared  to
$1,954,000  for the second quarter of 2002. The increase in revenue is primarily
due to the lower revenues  recorded in 2002 as a result of the failure of one of
the Providence Project's engines.

Gross profit  increased  $29,000 to $451,000 for the second quarter of 2003. The
increase is a result of the lower  maintenance  expenses recorded in the current
year as compared to 2002, when the Providence Project  experienced costly engine
repairs due to the failure of one of its engines.

General and  administrative  expenses decreased $48,000 in the second quarter of
2003 to $189,000.  The  management  fee  decreased  from  $156,000 in the second
quarter  of 2002 to  $142,000  for the same  period  in 2003 as a result  of the
Trust's lower net asset balance.

Interest  expense was reduced by $22,000 from  $58,000 in the second  quarter of
2002  to  $36,000  in  the  second  quarter  of  2003  due to  lower  borrowings
outstanding at the Providence Project.

Other income of $81,000 in the second quarter of 2002  decreased by $83,000,  to
an expense of $2,000 in the second quarter of 2003 primarily due to the proceeds
received from the  liquidation  of the Santee River Rubber  Company in the first
quarter of 2002.

Equity income from the Maine Hydro Projects  decreased by $112,000,  to $268,000
in the second  quarter of 2003.  The  decrease  is due to the  heavier  rainfall
experienced in the second quarter of 2002.

The equity income from the Maine Biomass  Projects  increased  $949,000,  from a
loss of $531,000 in the second quarter of 2002 to income of $418,000 in the same
period in 2003. The increase in equity income from the Maine Biomass Projects is
primarily  attributable to the $1,749,000 in revenues received from the transfer
of renewable energy credits.

Six Months Ended June 30, 2003, Compared to the Six Months Ended June 30, 2002

Total revenue for the first half of 2003 was $4,431,000,  compared to $3,931,000
for the first half of 2002.  The increase in revenue is  reflective of the lower
revenues  recorded in 2002 as a result of the  failure of one of the  Providence
Project's engines, offset by a decrease in the 2003 revenues from the California
Pumping projects due to the rainy weather experienced in Southern California. In
addition,  the  Providence  Project  recorded  the sale of $337,000 in the first
quarter of 2003 for the transfer of  renewable  energy  credits  produced in the
fourth quarter of 2002.

Gross profit increased  $531,000 to $1,225,000 for the first six months of 2003.
The  increase  is a result of the lower  maintenance  expenses  recorded  in the
current year as compared to 2002, when the Providence Project experienced costly
engine repairs due to the failure of one of its engines.

General and administrative expenses decreased $66,000 in the first six months of
2003 to $379,000.  The  management fee decreased from $312,000 in the first half
of 2002 to $284,000 for the same period in 2003 as a result of the Trust's lower
net asset balance.

Interest  expense  decreased  $46,000 from $124,000 in the first half of 2002 to
$78,000 in the second half of 2003 due to lower  borrowings  outstanding  at the
Providence Project.

Other income decreased by $203,000 in the first six months of 2003 primarily due
to the proceeds received from the liquidation of the Santee River Rubber Company
and the sale of obsolete equipment from the California Pumping project in 2002.

Equity income from the Maine Hydro Projects  decreased by $188,000,  to $210,000
in the  first  half  of  2003.  The  decrease  is due  to the  heavier  rainfall
experienced in 2002.

The equity income from the Maine Biomass Projects increased  $1,159,000,  from a
loss of  $912,000  in the first half of 2002 to income of  $247,000  in the same
period in 2003. The increase in equity income from the Maine Biomass Projects is
primarily  attributable to the $2,985,000 in revenues received from the transfer
of renewable energy credits.

Liquidity and Capital Resources

Cash provided by operating activities for the six months ended June 30, 2003 was
$1,408,000 compared to cash used by operating activities of $903,000 for the six
months ended June 30, 2002. The increase in cash flow from operating  activities
is primarily the result of the increase in net income and the proceeds  received
from an insurance claim.

Cash used in investing activities decreased by $367,000 during the first half of
2002 to $0 in the first half of 2003.  The decrease is due to the Trust making a
$325,000 investment in the Maine Biomass Projects in 2002.

Cash  provided  by  financing  activities  for the first six  months of 2002 was
$371,000  compared to a  $1,292,000  usage in the first six months of 2003.  The
decrease in cash flow from  financing  activities is due to the Trust  borrowing
$800,000  from  its  line  of  credit  in  2002,  as well  as the  Trust  making
distributions to shareholders of $722,000 in the current year.

On June 26, 2003, Ridgewood Renewable Power LLC, the Managing Shareholder of the
Trust,  entered into a $5,000,0000  Revolving Credit and Security Agreement with
Wachovia  Bank,  National   Association.   The  agreement  allows  the  Managing
Shareholder  to obtain loans and letters of credit for the benefit of the trusts
and funds that it manages.  The  agreement  expires on June 30, 2004. As part of
the  agreement,  the  Trust  agreed  to  limitations  on its  ability  to  incur
indebtedness and liens and make guarantees.

The Trust has historically  financed its operations from cash generated from its
subsidiaries  operations.  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 second quarter of 2000 but resumed making
distributions in the fourth quarter of 2002.

The Trust expects that its cash flows from operations, cash on hand and line of
credit will be sufficient to fund its obligations and any declared distributions
for the next twelve months.

Item 4. Controls and Procedures

Based on theirevaluation, as of a date within 90 days of the filing date of this
Form 10-Q, the Trust's Chief Executive  Officer and Chief Financial Officer have
concluded  that the Trust's  disclosure  controls and  procedures (as defined in
Rules  13a-14(c) and  15d-14(c)  under the  Securities  Exchange Act of 1934, as
amended)  are  effective.  There have been no  significant  changes in  internal
controls or in other  factors that could  significantly  affect  these  controls
subsequent to the date of their  evaluation,  including any  corrective  actions
with regard to significant deficiencies and material weaknesses.

Management has  identified  deficiencies  in the Trust's  ability to process and
summarize  financial  information  of  certain  individual  projects  and equity

address this deficiency.

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.

I, Robert E. Swanson,  Chief Executive Officer of Ridgewood Electric Power Trust
IV ("registrant"), certify that:

1. I have reviewed this quarterly report on Form 10-Q of the registrant;

2. Based on my  knowledge,  this  quarterly  report  does not contain any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made, not  misleading  with respect to the period covered by this quarterly
report;

3.  Based  on my  knowledge,  the  financial  statements,  and  other  financial
information  included in this quarterly  report,  fairly present in all material
respects the financial  condition,  results of operations  and cash flows of the

4.  The  registrant's  other  certifying  officer  and  I  are  responsible  for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we have:

    a)   designed such disclosure controls and procedures, or caused such
         disclosure control and procedures to be designed under our supervision,
         to ensure that material information relating to the registrant,
         including its consolidated subsidiaries, is made known to us by others
         within those entities, particularly during the period in which this
         quarterly report is being prepared;

    b)   evaluated the effectiveness of the registrant's disclosure controls and
         procedures and presented in this quarterly report our conclusions about
         the effectiveness of the disclosure controls and procedures, as of the
         end of the period covered by this quarterly report based on such
         evaluation; and

    c)   disclosed in this quarterly report any change in the registrant's
         internal control over financial reporting that occurred during the
         period covered by the report that has materially affected, or is
         reasonably likely to materially affect, the issuer's internal control
         over financial reporting; and


5. The registrant's other certifying officer and I have disclosed, based on our
most recent evaluation, to the registrant's auditors and senior management:

    a) all significant deficiencies in the design or operation of internal
       controls which could adversely affect the registrant's ability to record,
       process, summarize and report financial data and have identified for the
       registrant's auditors any material weaknesses in internal controls; and

    b) any fraud, whether or not material, that involves management or other
       employees who have a significant role in the registrant's internal
       controls; and

6. The  registrant's  other  certifying  officer  and I have  indicated  in this
quarterly  report  whether or not there  were  significant  changes in  internal
controls or in other factors that could  significantly  affect internal controls
subsequent to the date of our most recent  evaluation,  including any corrective
actions with regard to significant deficiencies and material weaknesses.
