1. DESCRIPTION OF BUSINESS

Ridgewood Electric Power Trust IV (the “Trust”) is a Delaware trust formed on September 8, 1994. The Trust began offering shares in February 1995 and concluded its offering in September 1996. The Trust has 476.8 investor shares of beneficial interest (“Investor Shares”) outstanding. Prior to the adoption of the Trust’s Plan of Dissolution (described below), the objective of the Trust was to provide benefits to its shareholders through a combination of distributions of operating cash flow and capital appreciation. The Managing Shareholder of the Trust is Ridgewood Renewable Power LLC, a New Jersey limited liability company (the “Managing Shareholder” or “RRP”). Historically, the Trust focused primarily on power generation facilities located in the US.

The Trust’s accompanying condensed consolidated financial statements include the accounts of the Trust and its former investment. The Trust owned a 35.2% interest in Rhode Island LFG Genco, LLC (“RILG”), which was sold in November 2010.

On November 19, 2010, the Trust, Ridgewood Electric Power Trust I (“Trust I”) (through its 100% ownership of Ridgewood Olinda LLC), Ridgewood Electric Power Trust III (“Trust III”) and Ridgewood Power B Fund/Providence Expansion (“B Fund”, and together with the Trust, Trust I and Trust III, the “Trusts”) sold all of their respective limited liability company membership interests in RILG to Broadrock Biopower I LLC (the “Buyer”), an entity affiliated with Macquarie Group Limited, an Australian based international company, as further discussed in Note 4.

On November 19, 2010, the date of the sale of RILG, the Plan of Liquidation and Dissolution of Ridgewood Electric Power Trust IV (the “Plan of Dissolution”) became effective. Under the Plan of Dissolution, the business of the Trust shifted, and became limited to the disposal of its remaining assets and resolution of its remaining liabilities. Upon the completion of these activities, if successful, the Managing Shareholder expects to distribute any remaining cash to the Trust’s shareholders and then proceed to terminate the Trust and its reporting obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Trust is required to make adequate provisions to satisfy its known and unknown liabilities, which could substantially delay or limit the Trust’s ability to make future distributions to shareholders. The process of accounting for the Trust’s liabilities, including those that are presently unknown, may involve difficult valuation decisions, which could adversely impact the amount or timing of any future distributions by the Trust.

Under the Plan of Dissolution, the Managing Shareholder has sole authority to conduct the Trust’s dissolution, liquidation and termination without additional shareholder approval. As of April 26, 2011, the Trust has not been liquidated, primarily due to holdback amounts due from the Buyer of RILG (see Note 4). The Trust does not anticipate any distributions until the Trust has completed the liquidation process, at which time, the Trust’s remaining cash, if any, will be distributed to its shareholders.

For the purposes of the Trust’s estimates of fees and expenses to be incurred during liquidation, management has assumed that the liquidation of the Trust will be completed by September 30, 2011. If the liquidation of the Trust, including the resolution of the matter discussed in Note 4, is not completed by that date, the actual expenses that the Trust will incur will likely increase.

The Trust has evaluated subsequent events and transactions through the date of the issuance of its financial statements, and concluded that there were no such events or transactions that require adjustment to, or disclosure in the notes to, the condensed consolidated financial statements.

2. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements are unaudited and have been prepared pursuant to the rules of the United States Securities and Exchange Commission (the “SEC”) and, in the opinion of management, include all adjustments that are necessary for a fair presentation of the condensed consolidated financial statements for the periods presented. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to SEC rules. These condensed consolidated financial statements should be read in conjunction with the Trust’s Annual Report on Form 10-K for the year ended December 31, 2010, filed with the SEC on February 25, 2011 (the “2010 Form 10-K”). No significant changes have been made to the Trust’s accounting policies and estimates disclosed in its 2010 Form 10-K.

The Trust’s condensed consolidated financial statements for periods prior to November 20, 2010 were prepared on the going concern basis of accounting, which contemplates realization of assets and satisfaction of liabilities in the normal course of business. Upon the effectiveness of the Trust’s Plan of Dissolution on November 20, 2010, the Trust began preparing its consolidated financial statements on the liquidation basis of accounting. This basis of accounting is considered appropriate when, among other things, liquidation of the Trust is probable. Under this basis of accounting, assets are valued at their estimated net realizable values and liabilities are valued at their estimated settlement amounts. The valuation of assets and liabilities requires management to make significant estimates and assumptions.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited, dollar amounts in thousands)

Upon conversion to the liquidation basis of accounting, the Trust accrued known estimated values of assets expected to be received and known estimated costs expected to be incurred in liquidation. On an ongoing basis, the Trust evaluates the estimates and assumptions that can have a significant impact on the Trust’s reported net assets in liquidation. Actual amounts may differ materially and adversely from these estimates. If there are delays in liquidating the Trust, actual costs incurred during the liquidation process would increase, reducing net assets available in liquidation and for future distributions to shareholders.

3. CASH AND CASH EQUIVALENTS

The Trust considers all highly liquid investments with maturities, when purchased, of three months or less as cash and cash equivalents. At March 31, 2011, cash and cash equivalents did not exceed federal insured limits.

4. INVESTMENT

On November 19, 2010, the Trusts sold all of their respective limited liability company membership interests in RILG to the Buyer for an initial aggregate gross sale price of $18,704, of which $6,584 was allocated to the Trust. The initial gross sale price included $1,010 in estimated net working capital of RILG, which was subject to adjustment within 90 days following the closing, to reflect the difference between estimated and actual net working capital at closing.

In connection with the indemnification obligations of the Trusts under the interest purchase agreement for the RILG sale, the Buyer held back $3,000 of the gross sale price of RILG, of which $1,056 was allocated to the Trust, for a period of 9 months after the closing of the sale. The holdback period is scheduled to end in August 2011. Subsequent to year-end, the estimated working capital calculation for RILG was finalized, resulting in $238 being owed to the Buyer, of which $84 was allocated to the Trust. The working capital adjustment resulted in a reduction of RILG’s portion of the Buyer’s holdback amount to $2,762, of which $972 is allocated to the Trust. In the absence of any claims for indemnification by the Buyer, the remaining holdback amount will be released to the Trusts in August 2011. As of the issuance of these financial statements, the Buyer has not notified the Trusts of any claims.

Summarized statements of operations data for RILG at March 31, 2010 was as follows:

Revenues	$	2,236

Gross loss		(1,198	)

Loss from operations		(2,091	)

Net loss		(2,091	)

Trust share of loss in RILG		(737	)

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This management’s discussion and analysis of the Trust as of March 31, 2011 is intended to help readers analyze the accompanying condensed consolidated financial statements, notes and other information contained in this document. This discussion and analysis should be read in conjunction with the accompanying condensed consolidated financial statements, notes and other information included elsewhere in this report as well as the consolidated financial statements, notes and other information and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the Trust’s 2010 Form 10-K.

Forward-Looking Statements

Certain statements discussed in this item and elsewhere in this Quarterly Report on Form 10-Q constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements generally relate to the Trust’s plans, objectives and expectations for future events and include statements about the Trust’s expectations, beliefs, plans, objectives, intentions, assumptions and other statements that are not historical facts. These statements are based upon management’s expectations, opinions and estimates as of the date they are made. Although management believes that the expectations, opinions and estimates reflected in these forward-looking statements are reasonable, such forward-looking statements are subject to known and unknown risks and uncertainties many of which may be beyond the Trust’s control, which could cause actual results, performance and achievements to differ materially from the results, performance and achievements projected, expected, expressed or implied by the forward-looking statements. Examples of events that could cause actual results to differ materially from historical results or those anticipated include:

possible contingent liabilities and risks associated with the dissolution and liquidation of the Trust, including, without limitation, settlement of the Trust’s liabilities and obligations,

costs incurred in connection with the carrying out of the plan of liquidation and dissolution of the Trust,

the actual timing of the completion of the liquidation process, and

the amount and timing of liquidating distributions, if any.

Additional information concerning the factors that could cause actual results to differ materially from those in the forward-looking statements is contained elsewhere in this report and in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in the Trust’s 2010 Form 10-K. Any forward-looking statement that the Trust makes, speaks only as of the date of this report. The Trust undertakes no obligation to publicly update or revise any forward-looking statements or cautionary factors, as a result of new information, future events or otherwise, except as required by law.

Liquidation Basis of Accounting

Upon conversion to the liquidation basis of accounting, the Trust accrued known estimated values of assets expected to be received and known estimated costs expected to be incurred during liquidation. On an ongoing basis, the Trust evaluates the estimates and assumptions that could have a significant impact on the Trust’s reported net assets in liquidation. Actual amounts may differ materially and adversely from these estimates. If there are delays in liquidating the Trust, actual costs incurred during the liquidation process would increase, reducing net assets available in liquidation and for future distributions to shareholders.

Critical Accounting Policies and Estimates

The discussion and analysis of the Trust’s financial condition and results of operations are based upon the Trust’s condensed consolidated financial statements, which have been prepared in conformity with GAAP. In preparing these financial statements, the Trust is required to make certain estimates, judgments and assumptions that affect the reported amount of the Trust’s assets, liabilities, revenues and expenses, including the disclosure of contingent assets and liabilities, as well as the reported amounts of changes in net assets. The estimates also affect the reported estimated value of net realizable assets and settlement of liabilities. The Trust evaluates these estimates and assumptions on an ongoing basis. The Trust bases its estimates and assumptions on historical experience and on various other factors that the Trust believes to be reasonable at the time the estimates and assumptions are made. However, future events and their effects cannot be predicted with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results may differ from these estimates and assumptions under different circumstances or conditions, and such differences may be material to the condensed consolidated financial statements. No material changes have been made to the Trust’s critical accounting policies and estimates disclosed in its 2010 Form 10-K.

Table of Contents

Results of Operations and Changes in Financial Condition

As the Trust adopted the liquidation basis of accounting effective November 20, 2010, any costs incurred and income received since then will be included in the condensed consolidated statements of changes in net assets.

Net assets at March 31, 2011 was $1.2 million, unchanged from net assets at December 31, 2010 as the Trust’s estimates of total liquidation accruals did not change during the quarter. During the quarter, the Trust’s cash balances decreased $385,000 as a result of payment of Trust liabilities, including the payment of management fees to the Managing Shareholder of $14,000.

For the purposes of the Trust’s estimates of fees and expenses to be incurred during liquidation, management has assumed that the liquidation of the Trust will be completed by September 30, 2011. If the liquidation of the Trust, including the resolution of the matter discussed in Part I, Item 5, Note 4 “Investment” of this report, is not completed by that date, the actual expenses that the Trust will incur will likely increase.

The condensed consolidated statement of operations and the statement of cash flows are presented on a going concern basis of accounting and therefore only include results for the three months ended March 31, 2010 and as a result, no comparative discussion is presented.

Future Liquidity and Capital Resource Requirements

The Trust believes it has sufficient cash and cash equivalents to provide working capital for the next 12 months. The Trust intends to distribute excess cash, if any, to its shareholders after liquidating its assets and satisfying its liabilities.

For a discussion of the Buyer holdback receivable in connection with the sale of RILG, see Note 4 “Investment” in the notes to the condensed consolidated financial statements in Part I, Item 1 of this report.

Off-Balance Sheet Arrangements, Contractual Obligations, Commitments and Contingencies

None.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not required.

ITEM 4. CONTROLS AND PROCEDURES

In accordance with Rule 13a-15(b) of the Exchange Act, the Trust’s management, with the participation of the Trust’s Chief Executive and Financial Officer, has evaluated the effectiveness of the Trust’s disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e). Based on this evaluation, the Trust’s Chief Executive and Financial Officer concluded that the Trust’s disclosure controls and procedures were effective as of the end of the period covered by this report to ensure that information required to be disclosed by the Trust in reports filed pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that information required to be disclosed by the Trust is accumulated and communicated to senior management so as to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

The Trust’s Chief Executive and Financial Officer has concluded that there was no change in the Trust's internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2011 that has materially affected, or is reasonably likely to materially affect, the Trust’s internal control over financial reporting.
