In this consolidated criminal case, 1 defendants were charged with the manufacture, delivery and possession of a controlled substance. ORS 475.992. Before trial, defendants moved to suppress evidence seized pursuant to a search warrant. The court allowed the motion to suppress, finding that the affidavit in support of the search warrant did not establish probable cause. The state appeals, and we affirm.
On November 26, 1991, Washington County Sheriffs Deputy Allen received a telephone call from Peggy Stark reporting a marijuana growing operation. Stark told Allen that she was living with one of the defendants (Milks) who, she said, had set up the operation. She also said that she and Milks had fought the day before. She told Allen the address and telephone number of the apartment where the operation was located, and that the name on the apartment’s telephone bill was Brian Desales. Stark reported numerous details that Milks had told her about the operation. Stark also recalled seeing what she thought were two or three grow lights in the back of Milks’ truck shortly after Milks rented the apartment.
Allen investigated Stark and her allegations and found that Stark had been convicted twice for filing false police reports. Allen also discovered that police officers had gone to Stark’s and Milks’ residence earlier that day on a domestic disturbance civil standby call. While on that call, the officers had arrested Milks on an outstanding warrant. Milks was interviewed while in custody, and he denied involvement in any growing operation. In that interview, Milks admitted using marijuana and was unable to identify two keys on his key ring. Milks was then released.
Allen also called Portland General Electric (PGE) to check on the apartment’s power consumption. A PGE representative told Allen that the current subscriber was Brian *400 Desales. Allen calculated the current subscriber’s average monthly power usage for March through August, 1991, and compared that figure to a previous tenant’s average monthly power usage for March to August, 1990. That comparison showed that the current subscriber used, on average, 1007 more kilowatts per month than the previous tenant. Allen knew through training and experience that the typical grow light uses approximately 360 kilowatts per month. He concluded that the increased electric usage supported the use of approximately two or three grow lights.
Allen relayed all of the above information to a magistrate on the evening of November 26, and the magistrate approved a search warrant. Police officers executed the warrant and found evidence that led to the indictment of the two defendants in this case.
At a pretrial hearing on a motion to suppress, defendants challenged the sufficiency of the affidavit underlying the search warrant. The trial court granted their motion to suppress, finding that the informant was not reliable and that, without the informant’s statements, there was insufficient evidence for a finding of probable cause on which to base a search warrant. The state appeals.
Our review of whether an affidavit is sufficient to support the issuance of a search warrant is
“to determine whether a neutral and detached magistrate could conclude, based on the facts and circumstances shown by the affidavit, that there was probable cause to believe that the search would discover things specified in the affidavit in the places requested to be searched. See ORS 133.555(1), (2). We are to construe the supporting affidavit in a commonsense and realistic fashion.” State v. Farrar,309 Or 132 , 144-45,786 P2d 161 , cert den498 US 879 (1990).
The state first challenges the trial court’s conclusion that the informant was not reliable. Most of the information in the affidavit was supplied by a named informant; therefore, we look to “the totality of the circumstances disclosed in the affidavit” to determine if the information provided by the informant is sufficiently reliable to support issuance of a search warrant.
State v. Young,
Most of the information in the affidavit came from Stark. She had personal knowledge of the information she provided. Stark was named in the affidavit, which supports the veracity of the informant.
State v. Carlile,
Even if an informant is not credible, the circumstances may assure that the particular information is trustworthy, or reliable, on a specific occasion.
State v. Alvarez, supra,
The circumstances assuring trustworthiness also include whether the information provided by the informant was corroborated.
State v. Farrar, supra,
Stark also relayed to Allen details that she asserted Milks had told her about the marijuana growing operation. Those details included the number of plants, the number of harvests since the operation began, the amount of money Milks had spent on the operation and other similar information. Those details were not corroborated and, thus, do not support Stark’s reliability. The state argues that the details were admissions against penal interest by Milks and, thus, entitled to belief. However, without corroboration to independently verify the details,
see, e.g., State v. Strance, supra,
*403 The state next argues that, even viewing Stark’s statements with caution, enough information was provided from other sources to establish probable cause. The other information on which the state relies is the analysis of the apartment’s electric usage and the information obtained from Milks in the custodial interview.
Allen compared the current tenant’s electric usage over a six-month period to a previous subscriber’s usage over the same six months two years previously. That comparison revealed something, but not enough, about either tenant; it revealed only their usage relative to each other. The magistrate had no way of knowing whether the current tenant’s power consumption was abnormally high, the previous tenant’s was abnormally low or whether both were within the range of normal use.

The fact that electric usage increases when a new tenant occupies a residence may be a part of the totality of the circumstances,
State v. Brotherton,
While Milks was in custody, he admitted that he had used marijuana and he could not identify two keys on his key ring. The state is correct that the admission of marijuana use
*404
does lend some credence to the other information, but it is not enough, standing alone, to supply probable cause. The fact that Milks could not identify keys on his ring “merely supports an inference that some other fact is possible — as one among the range of many other and different possibilities.”
State v. Carter/Grant, supra
n 5,
When no piece of information in an affidavit by itself is sufficient to constitute probable cause, the combined effect of all the information may still support the issuance of a search warrant.
State v. Strance, supra,
Affirmed.
Notes
Defendants Milks and Sales were allegedly involved in the same marijuana growing operation and were charged with the same offenses. They both filed motions to suppress based on the insufficiency of the affidavit supporting the search warrant. The cases were consolidated because they present the same issue: was the affidavit in support of the search warrant sufficient to support probable cause. However, the affidavit supporting the search warrant was based solely on Milks’ activities. Thus, if the affidavit was insufficient to constitute probable cause as to Milks, it was also insufficient to constitute probable cause as to Sales.
That test was developed in two United States Supreme Court cases,
Aguilar v. Texas,
Credibility refers to a person’s ongoing character as a truth-teller; the informant’s “demonstrated history of truth speaking.”
State v. Alvarez, supra,
Notwithstanding the lack of credibility and reliability of those statements, we still consider them in our final analysis of “the totality of the circumstances confronting the magistrate.”
Allen did divide the average monthly differential, 1,007 kilowatts, by the amount of electricity used by a lypical grow light, 360 kilowatts. Allen asserted in the affidavit that this “shows an approximate two or three grow lights usage” at the apartment. However, “particular facts must be alleged which provide a basis” for such inferences.
State v. Carter/Grant,
Such comparisons might include a comparison made by a utility company official who states that the defendant’s electric usage was excessive,
